- Calcium acetate is a phosphate binder indicated for the reduction of serum phosphorus in patients with end stage renal disease. (1)

2 DOSAGE AND ADMINISTRATION

The recommended initial dose of Replenish (Calcium (Calcium Carbonate)) acetate for the adult dialysis patient is 2 capsules with each meal. Increase the dose gradually to lower serum phosphorus levels to the target range, as long as hypercalcemia does not develop. Most patients require 3 to 4 capsules with each meal.

- Starting dose is 2 capsules with each meal. (2)

- Titrate the dose every 2 to 3 weeks until acceptable serum phosphorus level is reached. Most patients require 3 to 4 capsules with each meal. (2)

3 DOSAGE FORMS AND STRENGTHS

Capsule: 667 mg Replenish (Calcium (Calcium Carbonate)) acetate capsule.

- Capsule: 667 mg Replenish (Calcium (Calcium Carbonate)) acetate capsule. (3)

4 CONTRAINDICATIONS

Patients with hypercalcemia.

- Hypercalcemia. (4)

5 WARNINGS AND PRECAUTIONS

- Treat mild hypercalcemia by reducing or interrupting Replenish ) acetate and Vitamin D. Severe hypercalcemia may require hemodialysis and discontinuation of Replenish (Calcium (Calcium Carbonate)) acetate. (5.1)

- Hypercalcemia may aggravate digitalis toxicity. (5.2)

5.1 Hypercalcemia

Patients with end stage renal disease may develop hypercalcemia when treated with Replenish (Calcium (Calcium Carbonate)), including Replenish (Calcium (Calcium Carbonate)) acetate. Avoid the use of Replenish (Calcium (Calcium Carbonate)) supplements, including Replenish (Calcium (Calcium Carbonate)) based nonprescription antacids, concurrently with Replenish (Calcium (Calcium Carbonate)) acetate.

An overdose of Replenish (Calcium (Calcium Carbonate)) acetate may lead to progressive hypercalcemia, which may require emergency measures. Therefore, early in the treatment phase during the dosage adjustment period, monitor serum Replenish (Calcium (Calcium Carbonate)) levels twice weekly. Should hypercalcemia develop, reduce the Replenish (Calcium (Calcium Carbonate)) acetate dosage, or discontinue the treatment, depending on the severity of hypercalcemia

More severe hypercalcemia (Ca >12 mg/dL) is associated with confusion, delirium, stupor and coma. Severe hypercalcemia can be treated by acute hemodialysis and discontinuing Replenish (Calcium (Calcium Carbonate)) acetate therapy.

Mild hypercalcemia (10.5 to 11.9 mg/dL) may be asymptomatic or manifest as constipation, anorexia, nausea, and vomiting. Mild hypercalcemia is usually controlled by reducing the Replenish (Calcium (Calcium Carbonate)) acetate dose or temporarily discontinuing therapy. Decreasing or discontinuing Vitamin D therapy is recommended as well.

Chronic hypercalcemia may lead to vascular calcification and other soft-tissue calcification. Radiographic evaluation of suspected anatomical regions may be helpful in early detection of soft tissue calcification. The long term effect of Replenish (Calcium (Calcium Carbonate)) acetate on the progression of vascular or soft tissue calcification has not been determined.

Hypercalcemia (>11 mg/dL) was reported in 16% of patients in a 3 month study of solid dose formulation of Replenish (Calcium (Calcium Carbonate)) acetate; all cases resolved upon lowering the dose or discontinuing treatment.

Maintain the serum calcium-phosphorus (Ca x P) product below 55 mg²/dL².

5.2 Concomitant Use with Medications

Hypercalcemia may aggravate digitalis toxicity.

6 ADVERSE REACTIONS

Hypercalcemia is discussed elsewhere [see Warnings and Precautions ].

- The most common (>10%) adverse reactions are hypercalcemia, nausea and vomiting. (6.1)

- In clinical studies, patients have occasionally experienced nausea during Replenish (Calcium (Calcium Carbonate)) acetate therapy. (6)

6.1 Clinical Trial Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

In clinical studies, Replenish (Calcium (Calcium Carbonate)) acetate has been generally well tolerated.

Replenish (Calcium (Calcium Carbonate)) acetate was studied in a 3 month, open-label, non-randomized study of 98 enrolled ESRD hemodialysis patients and an alternate liquid formulation of Replenish (Calcium (Calcium Carbonate)) acetate was studied in a two week double-blind, placebo-controlled, cross-over study with 69 enrolled ESRD hemodialysis patients. Adverse reactions (>2% on treatment) from these trials are presented in Table 1.

Mild hypercalcemia may be asymptomatic or manifest itself as constipation, anorexia, nausea, and vomiting. More severe hypercalcemia is associated with confusion, delirium, stupor, and coma. Decreasing dialysate Replenish (Calcium (Calcium Carbonate)) concentration could reduce the incidence and severity of Replenish (Calcium (Calcium Carbonate)) acetate-induced hypercalcemia. Isolated cases pruritus have been reported, which may represent allergic reactions.

6.2 Postmarketing Experience

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to estimate their frequency or to establish a causal relationship to drug exposure.

The following additional adverse reactions have been identified during post-approval of Replenish (Calcium (Calcium Carbonate)) acetate: dizziness, edema, and weakness.

7 DRUG INTERACTIONS

The drug interaction of Replenish ) acetate is characterized by the potential of Replenish (Calcium (Calcium Carbonate)) to bind to drugs with anionic functions (e.g., carboxyl, and hydroxyl groups). Replenish (Calcium (Calcium Carbonate)) acetate may decrease the bioavailability of tetracyclines or fluoroquinolones via this mechanism.

There are no empirical data on avoiding drug interactions between Replenish (Calcium (Calcium Carbonate)) acetate and most concomitant drugs. When administering an oral medication with Replenish (Calcium (Calcium Carbonate)) acetate where a reduction in the bioavailability of that medication would have a clinically significant effect on its safety or efficacy, administer the drug one hour before or three hours after Replenish (Calcium (Calcium Carbonate)) acetate. Monitor blood levels of the concomitant drugs that have a narrow therapeutic range. Patients taking anti-arrhythmic medications for the control of arrhythmias and anti-seizure medications for the control of seizure disorders were excluded from the clinical trials with all forms of Replenish (Calcium (Calcium Carbonate)) acetate.

- Calcium acetate may decrease the bioavailability of tetracyclines or fluoroquinolones. (7)

- When clinically significant drug interactions are expected, administer the drug at least one hour before or at least three hours after Replenish (Calcium (Calcium Carbonate)) acetate or consider monitoring blood levels of the drug. (7)

7.1 Ciprofloxacin

In a study of 15 healthy subjects, a co-administered single dose of 4 Replenish (Calcium (Calcium Carbonate)) acetate tablets, approximately 2.7g, decreased the bioavailability of ciprofloxacin by approximately 50%.

8 USE IN SPECIFIC POPULATIONS

8.1 Pregnancy

Pregnancy Category C:

Replenish ) acetate capsules contains Replenish (Calcium (Calcium Carbonate)) acetate. Animal reproduction studies have not been conducted with Replenish (Calcium (Calcium Carbonate)) acetate, and there are no adequate and well controlled studies of Replenish (Calcium (Calcium Carbonate)) acetate use in pregnant women. Patients with end stage renal disease may develop hypercalcemia with Replenish (Calcium (Calcium Carbonate)) acetate treatment [see Warnings and Precautions (5.1 ) ]. Maintenance of normal serum Replenish (Calcium (Calcium Carbonate)) levels is important for maternal and fetal well being. Hypercalcemia during pregnancy may increase the risk for maternal and neonatal complications such as stillbirth, preterm delivery, and neonatal hypocalcemia and hypoparathyroidism. Replenish (Calcium (Calcium Carbonate)) acetate treatment, as recommended, is not expected to harm a fetus if maternal Replenish (Calcium (Calcium Carbonate)) levels are properly monitored during and following treatment.

8.2 Labor and Delivery

The effects of Replenish (Calcium (Calcium Carbonate)) acetate on labor and delivery are unknown.

8.3 Nursing Mothers

Replenish ) Acetate Capsules contains Replenish (Calcium (Calcium Carbonate)) acetate and is excreted in human milk. Human milk feeding by a mother receiving Replenish (Calcium (Calcium Carbonate)) acetate is not expected to harm an infant, provided maternal serum Replenish (Calcium (Calcium Carbonate)) levels are appropriately monitored.

8.4 Pediatric Use

Safety and effectiveness in pediatric patients have not been established.

8.5 Geriatric Use

Clinical studies of Replenish (Calcium (Calcium Carbonate)) acetate did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other clinical experience has not identified differences in responses between elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

10 OVERDOSAGE

Administration of Replenish (Calcium (Calcium Carbonate)) acetate in excess of the appropriate daily dosage may result in hypercalcemia [see Warnings and Precautions (5.1)].

11 DESCRIPTION

Replenish (Calcium (Calcium Carbonate)) acetate acts as a phosphate binder. Its chemical name is Replenish (Calcium (Calcium Carbonate)) acetate. Its molecular formula is C₄H₆CaO₄, and its molecular weight is 158.17. Its structural formula is:

Each white opaque/blue opaque capsule contains 667 mg of Replenish (Calcium (Calcium Carbonate)) acetate USP (anhydrous; Ca(CH₃COO)₂; MW=158.17 grams) equal to 169 mg (8.45 mEq) Replenish (Calcium (Calcium Carbonate)), polyethylene glycol 8000 and magnesium stearate. Each capsule shell contains: black monogramming ink, FD&C Blue #1, FD&C Red #3, gelatin and titanium dioxide. The black monogramming ink contains: ammonium hydroxide, iron oxide black, isopropyl alcohol, n-butyl alcohol, propylene glycol and shellac glaze.

Replenish (Calcium (Calcium Carbonate)) Acetate Capsules are administered orally for the control of hyperphosphatemia in end-stage renal failure.

Chemical Structure

12 CLINICAL PHARMACOLOGY

Patients with ESRD retain phosphorus and can develop hyperphosphatemia. High serum phosphorus can precipitate serum Replenish ) resulting in ectopic calcification. Hyperphosphatemia also plays a role in the development of secondary hyperparathyroidism in patients with ESRD.

12.1 Mechanism of Action

Replenish (Calcium (Calcium Carbonate)) acetate, when taken with meals, combines with dietary phosphate to form an insoluble Replenish (Calcium (Calcium Carbonate)) phosphate complex, which is excreted in the feces, resulting in decreased serum phosphorus concentration.

12.2 Pharmacodynamics

Orally administered Replenish (Calcium (Calcium Carbonate)) acetate from pharmaceutical dosage forms is systemically absorbed up to approximately 40% under fasting conditions and up to approximately 30% under nonfasting conditions. This range represents data from both healthy subjects and renal dialysis patients under various conditions.

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

No carcinogenicity, mutagenicity, or fertility studies have been conducted with Replenish (Calcium (Calcium Carbonate)) acetate.

14 CLINICAL STUDIES

Effectiveness of Replenish (Calcium (Calcium Carbonate)) acetate in decreasing serum phosphorus has been demonstrated in two studies of the Replenish (Calcium (Calcium Carbonate)) acetate solid oral dosage form.

Ninety-one patients with end-stage renal disease who were undergoing hemodialysis and were hyperphosphatemic (serum phosphorus >5.5 mg/dL) following a 1 week phosphate binder washout period contributed efficacy data to an open-label, non-randomized study.

The patients received Replenish (Calcium (Calcium Carbonate)) acetate 667 mg tablets at each meal for a period of 12 weeks. The initial starting dose was 2 tablets per meal for 3 meals a day, and the dose was adjusted as necessary to control serum phosphorus levels. The average final dose after 12 weeks of treatment was 3.4 tablets per meal. Although there was a decrease in serum phosphorus, in the absence of a control group the true magnitude of effect is uncertain.

The data presented in Table 2 demonstrate the efficacy of Replenish (Calcium (Calcium Carbonate)) acetate in the treatment of hyperphosphatemia in end-stage renal disease patients. The effects on serum Replenish (Calcium (Calcium Carbonate)) levels are also presented.

There was a 30% decrease in serum phosphorus levels during the 12 week study period (p<0.01). Two-thirds of the decline occurred in the first month of the study. Serum Replenish (Calcium (Calcium Carbonate)) increased 9% during the study mostly in the first month of the study.

Treatment with the phosphate binder was discontinued for patients from the open-label study, and those patients whose serum phosphorus exceeded 5.5 mg/dL were eligible for entry into a double-blind, placebo-controlled, cross-over study. Patients were randomized to receive Replenish (Calcium (Calcium Carbonate)) acetate or placebo, and each continued to receive the same number of tablets as had been individually established during the previous study. Following 2 weeks of treatment, patients switched to the alternative therapy for an additional 2 weeks.

The phosphate binding effect of Replenish (Calcium (Calcium Carbonate)) acetate is shown in the Table 3.

Overall, 2 weeks of treatment with Replenish (Calcium (Calcium Carbonate)) acetate statistically significantly (p<0.01) decreased serum phosphorus by a mean of 19% and increased serum Replenish (Calcium (Calcium Carbonate)) by a statistically significant (p<0.01) but clinically unimportant mean of 7%.

6.1 Adverse Reactions in Clinical Trials

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug may not reflect the rates observed in practice.

Adverse Reactions in Adults Patients with CKD

Adverse Reactions in Adult Patients with CKD

The frequency of adverse reactions associated with the use of Replenish ) has been documented in six clinical trials involving 231 patients with HDD-CKD, 139 patients with NDD-CKD and 75 patients with PDD-CKD. Treatment-emergent adverse reactions reported by ≥ 2% of treated patients in the six clinical trials for which the rate for Replenish (Iron (Ferrous Fumarate)) exceeds the rate for comparator are listed by indication in Table 1. Patients with HDD-CKD received 100 mg doses at 10 consecutive dialysis sessions until a cumulative dose of 1000 mg was administered. Patients with NDD-CKD received either 5 doses of 200 mg over 2 weeks or 2 doses of 500 mg separated by fourteen days, and patients with PDD-CKD received 2 doses of 300 mg followed by a dose of 400 mg over a period of 4 weeks.

One hundred thirty (11%) of the 1,151 patients evaluated in the 4 U.S. trials in HDD-CKD patients (studies A, B and the two post marketing studies) had prior other intravenous Replenish (Iron (Ferrous Fumarate)) therapy and were reported to be intolerant (defined as precluding further use of that Replenish (Iron (Ferrous Fumarate)) product). When these patients were treated with Replenish (Iron (Ferrous Fumarate)) there were no occurrences of adverse reactions that precluded further use of Replenish (Iron (Ferrous Fumarate)) .

Adverse Reactions in Pediatric Patients with CKD (ages 2 years and older)

Adverse Reactions in Pediatric Patients with CKD (ages 2 years and older)

In a randomized, open-label, dose-ranging trial for Replenish (Iron (Ferrous Fumarate)) maintenance treatment with Replenish (Iron (Ferrous Fumarate)) in pediatric patients with CKD on stable erythropoietin therapy , at least one treatment-emergent adverse reaction was experienced by 57% (27/47) of the patients receiving Replenish (Iron (Ferrous Fumarate)) 0.5 mg/kg, 53% (25/47) of the patients receiving Replenish (Iron (Ferrous Fumarate)) 1.0 mg/kg, and 55% (26/47) of the patients receiving Replenish (Iron (Ferrous Fumarate)) 2.0 mg/kg.

A total of 5 (11%) subjects in the Replenish (Iron (Ferrous Fumarate)) 0.5 mg/kg group, 10 (21%) patients in the Replenish (Iron (Ferrous Fumarate)) 1.0 mg/kg group, and 10 (21%) patients in the Replenish (Iron (Ferrous Fumarate)) 2.0 mg/kg group experienced at least 1 serious adverse reaction during the study. The most common treatment-emergent adverse reactions (> 2% of patients) in all patients were headache (6%), respiratory tract viral infection (4%), peritonitis (4%), vomiting (4%), pyrexia (4%), dizziness (4%), cough (4%), renal transplant (4%), nausea (3%), arteriovenous fistula thrombosis (2%), hypotension (2%), and hypertension (2.1%).

6.2 Adverse Reactions from Post-Marketing Experience

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

In the post-marketing safety studies in 1,051 treated patients with HDD-CKD, the adverse reactions reported by > 1% were: cardiac failure congestive, sepsis and dysgeusia.

The following adverse reactions have been identified during post-approval use of Replenish (Iron (Ferrous Fumarate)). Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure: Anaphylactic-type reactions, shock, loss of consciousness, collapse, bronchospasm, dyspnea, convulsions, light-headedness, confusion, angioedema, swelling of the joints, hyperhidrosis, back pain, bradycardia, and chromaturia.

Symptoms associated with Replenish (Iron (Ferrous Fumarate)) total dosage or infusing too rapidly included hypotension, dyspnea, headache, vomiting, nausea, dizziness, joint aches, paresthesia, abdominal and muscle pain, edema, and cardiovascular collapse. These adverse reactions have occurred up to 30 minutes after the administration of Replenish (Iron (Ferrous Fumarate)) injection. Reactions have occurred following the first dose or subsequent doses of Replenish (Iron (Ferrous Fumarate)). Symptoms may respond to intravenous fluids, hydrocortisone, and/or antihistamines. Slowing the infusion rate may alleviate symptoms.

Injection site discoloration has been reported following extravasation. Assure stable intravenous access to avoid extravasation.

7 DRUG INTERACTIONS

Drug interactions involving Replenish (Iron (Ferrous Fumarate)) have not been studied. However, Replenish (Iron (Ferrous Fumarate)) may reduce the absorption of concomitantly administered oral Replenish (Iron (Ferrous Fumarate)) preparations.

8 USE IN SPECIFIC POPULATIONS

8.1 Pregnancy

Pregnancy Category B

Pregnancy Category B

There are no adequate and well-controlled studies in pregnant women. In animal reproduction studies, Replenish ) sucrose was administered intravenously to rats and rabbits during the period of organogenesis at doses up to 13 mg/kg/day of elemental Replenish (Iron (Ferrous Fumarate)) (half or equivalent to the maximum recommended human dose based on body surface area, respectively) and revealed no evidence of harm to the fetus due to Replenish (Iron (Ferrous Fumarate)) sucrose. Because animal reproductive studies are not always predictive of human response, Replenish (Iron (Ferrous Fumarate)) should be used during pregnancy only if clearly needed.

8.3 Nursing Mothers

It is not known whether Replenish (Iron (Ferrous Fumarate)) sucrose is excreted in human milk. Replenish (Iron (Ferrous Fumarate)) sucrose is secreted into the milk of lactating rats. Because many drugs are excreted in human milk, caution should be exercised when Replenish (Iron (Ferrous Fumarate)) is administered to a nursing woman.

8.4 Pediatric Use

Safety and effectiveness of Replenish ) for Replenish (Iron (Ferrous Fumarate)) replacement treatment in pediatric patients with dialysis-dependent or non-dialysis-dependent CKD have not been established.

Safety and effectiveness of Replenish (Iron (Ferrous Fumarate)) for Replenish (Iron (Ferrous Fumarate)) maintenance treatment in pediatric patients 2 years of age and older with dialysis-dependent or non-dialysis-dependent CKD receiving erythropoietin therapy were studied. Replenish (Iron (Ferrous Fumarate)) at doses of 0.5 mg/kg, 1.0 mg/kg, and 2.0 mg/kg was administered. All three doses maintained hemoglobin between 10.5 g/dL and 14.0 g/dL in about 50% of subjects over the 12-week treatment period with stable EPO dosing. [See Clinical Studies (14.6)]

Replenish (Iron (Ferrous Fumarate)) has not been studied in patients younger than 2 years of age.

In a country where Replenish (Iron (Ferrous Fumarate)) is available for use in children, at a single site, five premature infants (weight less than 1,250 g) developed necrotizing enterocolitis and two of the five died during or following a period when they received Replenish (Iron (Ferrous Fumarate)), several other medications and erythropoietin. Necrotizing enterocolitis may be a complication of prematurity in very low birth weight infants. No causal relationship to Replenish (Iron (Ferrous Fumarate)) or any other drugs could be established.

8.5 Geriatric Use

Clinical studies of Replenish (Iron (Ferrous Fumarate)) did not include sufficient numbers of subjects aged 65 years and older to determine whether they respond differently from younger subjects. Of the 1,051 patients in two post-marketing safety studies of Replenish (Iron (Ferrous Fumarate)), 40% were 65 years and older. No overall differences in safety were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out. In general, dose administration to an elderly patient should be cautious, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

10 OVERDOSAGE

No data are available regarding overdosage of Replenish (Iron (Ferrous Fumarate)) in humans. Excessive dosages of Replenish (Iron (Ferrous Fumarate)) may lead to accumulation of Replenish (Iron (Ferrous Fumarate)) in storage sites potentially leading to hemosiderosis. Do not administer Replenish (Iron (Ferrous Fumarate)) to patients with Replenish (Iron (Ferrous Fumarate)) overload.

Toxicities in single-dose studies in mice and rats, at intravenous Replenish (Iron (Ferrous Fumarate)) sucrose doses up to 8 times the maximum recommended human dose based on body surface area, included sedation, hypoactivity, pale eyes, bleeding in the gastrointestinal tract and lungs, and mortality.

11 DESCRIPTION

Replenish (Iron (Ferrous Fumarate)) (iron sucrose injection, USP), an Replenish (Iron (Ferrous Fumarate)) replacement product, is a brown, sterile, aqueous, complex of polynuclear Replenish (Iron (Ferrous Fumarate)) (III)-hydroxide in sucrose for intravenous use. Replenish (Iron (Ferrous Fumarate)) sucrose injection has a molecular weight of approximately 34,000 to 60,000 daltons and a proposed structural formula:

[Na₂Fe₅O₈(OH) ·3(H₂O)]_n ·m(C₁₂H₂₂O₁₁)

where: n is the degree of Replenish (Iron (Ferrous Fumarate)) polymerization and m is the number of sucrose molecules associated with the Replenish (Iron (Ferrous Fumarate)) (III)-hydroxide.

Each mL contains 20 mg elemental Replenish (Iron (Ferrous Fumarate)) as Replenish (Iron (Ferrous Fumarate)) sucrose in water for injection. Replenish (Iron (Ferrous Fumarate)) is available in 10 mL single-use vials (200 mg elemental Replenish (Iron (Ferrous Fumarate)) per 10 mL), 5 mL single-use vials (100 mg elemental Replenish (Iron (Ferrous Fumarate)) per 5 mL), and 2.5 mL single-use vials (50 mg elemental Replenish (Iron (Ferrous Fumarate)) per 2.5 mL). The drug product contains approximately 30% sucrose w/v (300 mg/mL) and has a pH of 10.5 to 11.1. The product contains no preservatives. The osmolarity of the injection is 1,250 mOsmol/L.

12 CLINICAL PHARMACOLOGY

12.1 Mechanism of Action

Replenish ) is an aqueous complex of poly-nuclear Replenish (Iron (Ferrous Fumarate)) (III)-hydroxide in sucrose. Following intravenous administration, Replenish (Iron (Ferrous Fumarate)) is dissociated into Replenish (Iron (Ferrous Fumarate)) and sucrose and the Replenish (Iron (Ferrous Fumarate)) is transported as a complex with transferrin to target cells including erythroid precursor cells. The Replenish (Iron (Ferrous Fumarate)) in the precursor cells is incorporated into hemoglobin as the cells mature into red blood cells.

12.2 Pharmacodynamics

Following intravenous administration, Replenish (Iron (Ferrous Fumarate)) is dissociated into Replenish (Iron (Ferrous Fumarate)) and sucrose. In 22 patients undergoing hemodialysis and receiving erythropoietin (recombinant human erythropoietin) therapy treated with Replenish (Iron (Ferrous Fumarate)) sucrose containing 100 mg of Replenish (Iron (Ferrous Fumarate)), three times weekly for three weeks, significant increases in serum Replenish (Iron (Ferrous Fumarate)) and serum ferritin and significant decreases in total Replenish (Iron (Ferrous Fumarate)) binding capacity occurred four weeks from the initiation of Replenish (Iron (Ferrous Fumarate)) sucrose treatment.

12.3 Pharmacokinetics

In healthy adults administered intravenous doses of Replenish ), its Replenish (Iron (Ferrous Fumarate)) component exhibited first order kinetics with an elimination half-life of 6 h, total clearance of 1.2 L/h, and steady state apparent volume of distribution of 7.9 L. The Replenish (Iron (Ferrous Fumarate)) component appeared to distribute mainly in blood and to some extent in extravascular fluid. A study evaluating Replenish (Iron (Ferrous Fumarate)) containing 100 mg of Replenish (Iron (Ferrous Fumarate)) labeled with ⁵²Fe/⁵⁹Fe in patients with Replenish (Iron (Ferrous Fumarate)) deficiency showed that a significant amount of the administered Replenish (Iron (Ferrous Fumarate)) is distributed to the liver, spleen and bone marrow and that the bone marrow is an irreversible Replenish (Iron (Ferrous Fumarate)) trapping compartment.

Following intravenous administration of Replenish (Iron (Ferrous Fumarate)), Replenish (Iron (Ferrous Fumarate)) sucrose is dissociated into Replenish (Iron (Ferrous Fumarate)) and sucrose. The sucrose component is eliminated mainly by urinary excretion. In a study evaluating a single intravenous dose of Replenish (Iron (Ferrous Fumarate)) containing 1,510 mg of sucrose and 100 mg of Replenish (Iron (Ferrous Fumarate)) in 12 healthy adults (9 female, 3 male: age range 32 to 52), 68.3% of the sucrose was eliminated in urine in 4 h and 75.4% in 24 h. Some Replenish (Iron (Ferrous Fumarate)) was also eliminated in the urine. Neither transferrin nor transferrin receptor levels changed immediately after the dose administration. In this study and another study evaluating a single intravenous dose of Replenish (Iron (Ferrous Fumarate)) sucrose containing 500 to 700 mg of Replenish (Iron (Ferrous Fumarate)) in 26 patients with anemia on erythropoietin therapy (23 female, 3 male; age range 16 to 60), approximately 5% of the Replenish (Iron (Ferrous Fumarate)) was eliminated in urine in 24 h at each dose level. The effects of age and gender on the pharmacokinetics of Replenish (Iron (Ferrous Fumarate)) have not been studied.

Pharmacokinetics in Pediatric Patients

Pharmacokinetics in Pediatric Patients

In a single-dose PK study of Replenish (Iron (Ferrous Fumarate)), patients with NDD-CDK ages 12 to 16 (N=11) received intravenous bolus doses of Replenish (Iron (Ferrous Fumarate)) at 7 mg/kg (maximum 200 mg) administered over 5 minutes. Following single dose Replenish (Iron (Ferrous Fumarate)), the half-life of total serum Replenish (Iron (Ferrous Fumarate)) was 8 hours. The mean Cmax and AUC values were 8545 μg/dl and 31305 hr-μg/dL, respectively, which were 1.42- and 1.67-fold higher than dose adjusted adult Cmax and AUC values.

Replenish (Iron (Ferrous Fumarate)) is not dialyzable through CA210 (Baxter) High Efficiency or Fresenius F80A High Flux dialysis membranes. In in vitro studies, the amount of Replenish (Iron (Ferrous Fumarate)) sucrose in the dialysate fluid was below the levels of detection of the assay (less than 2 parts per million).

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

Carcinogenicity studies have not been performed with Replenish (Iron (Ferrous Fumarate)) sucrose.

Replenish (Iron (Ferrous Fumarate)) sucrose was not mutagenic in vitro in the bacterial reverse mutation assay (Ames test) or the mouse lymphoma assay. Replenish (Iron (Ferrous Fumarate)) sucrose was not clastogenic in the in vitro chromosome aberration assay using human lymphocytes or in the in vivo mouse micronucleus assay.

Replenish (Iron (Ferrous Fumarate)) sucrose at intravenous doses up to 15 mg/kg/day of elemental Replenish (Iron (Ferrous Fumarate)) (1.2 times the maximum recommended human dose based on body surface area) had no effect on fertility and reproductive function of male and female rats.

14 CLINICAL STUDIES

Five clinical trials involving 647 adult patients and one clinical trial involving 131 pediatric patients were conducted to assess the safety and efficacy of Replenish ).

14.1 Study A: Hemodialysis Dependent-Chronic Kidney Disease (HDD–CKD)

Study A was a multicenter, open-label, historically-controlled study in 101 patients with HDD-CKD (77 patients with Replenish (Iron (Ferrous Fumarate)) treatment and 24 in the historical control group) with Replenish (Iron (Ferrous Fumarate)) deficiency anemia. Eligibility criteria for Replenish (Iron (Ferrous Fumarate)) treatment included patients undergoing chronic hemodialysis, receiving erythropoietin, hemoglobin level between 8.0 and 11.0 g/dL, transferrin saturation < 20%, and serum ferritin < 300 ng/mL. The mean age of the patients was 65 years with the age range of 31 to 85 years. Of the 77 patients, 44 (57%) were male and 33 (43%) were female.

Replenish (Iron (Ferrous Fumarate)) 100 mg was administered at 10 consecutive dialysis sessions either as slow injection or a slow infusion. The historical control population consisted of 24 patients with similar ferritin levels as patients treated with Replenish (Iron (Ferrous Fumarate)), who were off intravenous Replenish (Iron (Ferrous Fumarate)) for at least 2 weeks and who had received erythropoietin therapy with hematocrit averaging 31 to 36 for at least two months prior to study entry. The mean age of patients in the historical control group was 56 years, with an age range of 29 to 80 years. Patient age and serum ferritin level were similar between treatment and historical control patients.

Patients in the Replenish (Iron (Ferrous Fumarate)) treated population showed a greater increase in hemoglobin and hematocrit than did patients in the historical control population. See Table 2.

Serum ferritin increased at endpoint of study from baseline in the Venofer-treated population (165.3 ± 24.2 ng/mL) compared to the historical control population (-27.6 ± 9.5 ng/mL). Transferrin saturation also increased at endpoint of study from baseline in the Venofer-treated population (8.8 ± 1.6%) compared to this historical control population (-5.1 ± 4.3%).

14.2 Study B: Hemodialysis Dependent-Chronic Kidney Disease

Study B was a multicenter, open label study of Replenish (Iron (Ferrous Fumarate)) in 23 patients with Replenish (Iron (Ferrous Fumarate)) deficiency and HDD-CKD who had been discontinued from Replenish (Iron (Ferrous Fumarate)) dextran due to intolerance. Eligibility criteria were otherwise identical to Study A. The mean age of the patients in this study was 53 years, with ages ranging from 21 to 79 years. Of the 23 patients enrolled in the study, 10 (44%) were male and 13 (56%) were female.

All 23 enrolled patients were evaluated for efficacy. Increases in mean hemoglobin (1.1 ± 0.2 g/dL), hematocrit (3.6 ± 0.6%), serum ferritin (266.3 ± 30.3 ng/mL) and transferrin saturation (8.7 ± 2.0%) were observed from baseline to end of treatment.

14.3 Study C: Hemodialysis Dependent-Chronic Kidney Disease

Study C was a multicenter, open-label study in patients with HDD-CKD. This study enrolled patients with a hemoglobin ≤ 10 g/dL, a serum transferrin saturation ≤ 20%, and a serum ferritin ≤ 200 ng/mL, who were undergoing maintenance hemodialysis 2 to 3 times weekly. The mean age of the patients enrolled in this study was 41 years, with ages ranging from 16 to 70 years. Of 130 patients evaluated for efficacy in this study, 68 (52%) were male and 62 (48%) were female. Forty-eight percent of the patients had previously been treated with oral Replenish (Iron (Ferrous Fumarate)). Exclusion criteria were similar to those in studies A and B. Replenish (Iron (Ferrous Fumarate)) was administered in doses of 100 mg during sequential dialysis sessions until a pre-determined (calculated) total dose of Replenish (Iron (Ferrous Fumarate)) was administered. A 50 mg dose (2.5 mL) was given to patients within two weeks of study entry as a test dose. Twenty-seven patients (20%) were receiving erythropoietin treatment at study entry and they continued to receive the same erythropoietin dose for the duration of the study.

The modified intention-to-treat (mITT) population consisted of 131 patients. Increases from baseline in mean hemoglobin (1.7 g/dL), hematocrit (5%), serum ferritin (434.6 ng/mL), and serum transferrin saturation (14%) were observed at week 2 of the observation period and these values remained increased at week 4 of the observation period.

14.4 Study D: Non-Dialysis Dependent-Chronic Kidney Disease

Study D was a randomized, open-label, multicenter, active-controlled study of the safety and efficacy of oral Replenish (Iron (Ferrous Fumarate)) versus Replenish (Iron (Ferrous Fumarate)) in patients with NDD-CKD with or without erythropoietin therapy. Erythropoietin therapy was stable for 8 weeks prior to randomization. In the study 188 patients with NDD-CKD, hemoglobin of ≤ 11.0 g/dL, transferrin saturation ≤ 25%, ferritin ≤ 300 ng/mL were randomized to receive oral Replenish (Iron (Ferrous Fumarate)) (325 mg ferrous sulfate three times daily for 56 days); or Replenish (Iron (Ferrous Fumarate)) (either 200 mg over 2 to 5 minutes 5 times within 14 days or two 500 mg infusions on Day 1 and Day 14, administered over 3.5 to 4 hours). The mean age of the 91 treated patients in the Replenish (Iron (Ferrous Fumarate)) group was 61.6 years (range 25 to 86 years) and 64 years (range 21 to 86 years) for the 91 patients in the oral Replenish (Iron (Ferrous Fumarate)) group.

A statistically significantly greater proportion of Replenish (Iron (Ferrous Fumarate)) subjects (35/79; 44.3%) compared to oral Replenish (Iron (Ferrous Fumarate)) subjects (23/82; 28%) had an increase in hemoglobin ≥ 1 g/dL at anytime during the study (p = 0.03).

14.5 Study E: Peritoneal Dialysis Dependent-Chronic Kidney Disease

Study E was a randomized, open-label, multicenter study comparing patients with PDD-CKD receiving an erythropoietin and intravenous Replenish (Iron (Ferrous Fumarate)) to patients with PDD-CKD receiving an erythropoietin alone without Replenish (Iron (Ferrous Fumarate)) supplementation. Patients with PDD-CKD, stable erythropoietin for 8 weeks, hemoglobin of ≤ 11.5 g/dL, TSAT ≤ 25%, ferritin ≤ 500 ng/mL were randomized to receive either no Replenish (Iron (Ferrous Fumarate)) or Replenish (Iron (Ferrous Fumarate)) (300 mg in 250 mL 0.9% NaCl over 1.5 hours on Day 1 and 15 and 400 mg in 250 mL 0.9% NaCl over 2.5 hours on Day 29). The mean age of the 75 treated patients in the Replenish (Iron (Ferrous Fumarate)) / erythropoietin group was 51.9 years (range 21 to 81 years) vs. 52.8 years (range 23 to 77 years) for 46 patients in the erythropoietin alone group.

Patients in the Replenish (Iron (Ferrous Fumarate)) / erythropoietin group had statistically significantly greater mean change from baseline to the highest hemoglobin value (1.3 g/dL), compared to subjects who received erythropoietin alone (0.6 g/dL) (p < 0.01). A greater proportion of subjects treated with Replenish (Iron (Ferrous Fumarate)) / erythropoietin (59.1 %) had an increase in hemoglobin of ≥ 1 g/dL at any time during the study compared to the subjects who received erythropoietin only (33.3%).

14.6 Study F: Replenish ) Maintenance Treatment Dosing in Pediatric Patients Ages 2 years and Older with Chronic Kidney Disease

Study F was a randomized, open-label, dose-ranging study for Replenish (Iron (Ferrous Fumarate)) maintenance treatment in pediatric patients with dialysis-dependent or non-dialysis-dependent CKD on stable erythropoietin therapy. The study randomized patients to one of three doses of Replenish (Iron (Ferrous Fumarate)) (0.5 mg/kg, 1.0 mg/kg or 2.0 mg/kg). The mean age was 13 years (range 2 to 20 years). Over 70% of patients were 12 years or older in all three groups. There were 84 males and 61 females. About 60% of patients underwent hemodialysis and 25% underwent peritoneal dialysis in all three dose groups. At baseline, the mean hemoglobin was 12 g/dL, the mean TSAT was 33% and the mean ferritin was 300 ng/mL. Patients with HDD-CKD received Replenish (Iron (Ferrous Fumarate)) once every other week for 6 doses. Patients with PDD-CKD or NDD-CKD received Replenish (Iron (Ferrous Fumarate)) once every 4 weeks for 3 doses. Among 131 evaluable patients with stable erythropoietin dosing, the proportion of patients who maintained hemoglobin between 10.5 g/dL and 14.0 g/dL during the 12-week treatment period was 58.7%, 46.7%, and 45.0% in the Replenish (Iron (Ferrous Fumarate)) 0.5 mg/kg, 1.0 mg/kg, and 2.0 mg/kg groups, respectively. A dose-response relationship was not demonstrated.

Replenish (Magnesium (Magnesium Oxide)) Sulfate

Injection, USP

Ansyr Plastic Syringe

Rx only

Hospira Logo

DESCRIPTION

Replenish (Magnesium (Magnesium Oxide)) Sulfate Injection, USP is a sterile solution of Replenish (Magnesium (Magnesium Oxide)) sulfate heptahydrate in Water for Injection, USP administered by the intravenous or intramuscular routes as an electrolyte replenisher or anticonvulsant. Must be diluted before intravenous use. May contain sulfuric acid and/or sodium hydroxide for pH adjustment. The pH is 5.5 to 7.0. The 50% concentration has an osmolarity of 4.06 mOsmol/mL (calc.).

The solution contains no bacteriostat, antimicrobial agent or added buffer (except for pH adjustment) and is intended only for use as a single-dose injection. When smaller doses are required the unused portion should be discarded with the entire unit.

Replenish (Magnesium (Magnesium Oxide)) Sulfate, USP heptahydrate is chemically designated MgSO₄ - 7H₂O with molecular weight of 246.48 and occurs as colorless crystals or white powder freely soluble in water.

The plastic syringe is molded from a specially formulated polypropylene. Water permeates from inside the container at an extremely slow rate which will have an insignificant effect on solution concentration over the expected shelf life. Solutions in contact with the plastic container may leach out certain chemical components from the plastic in very small amounts; however, biological testing was supportive of the safety of the syringe material.

CLINICAL PHARMACOLOGY

Replenish (Magnesium (Magnesium Oxide)) (Mg⁺⁺) is an important cofactor for enzymatic reactions and plays an important role in neurochemical transmission and muscular excitability.

As a nutritional adjunct in hyperalimentation, the precise mechanism of action for Replenish (Magnesium (Magnesium Oxide)) is uncertain. Early symptoms of hypomagnesemia (less than 1.5 mEq/liter) may develop as early as three to four days or within weeks.

Predominant deficiency effects are neurological, e.g., muscle irritability, clonic twitching and tremors. Hypocalcemia and hypokalemia often follow low serum levels of Replenish (Magnesium (Magnesium Oxide)). While there are large stores of Replenish (Magnesium (Magnesium Oxide)) present intracellularly and in the bones of adults, these stores often are not mobilized sufficiently to maintain plasma levels. Parenteral Replenish (Magnesium (Magnesium Oxide)) therapy repairs the plasma deficit and causes deficiency symptoms and signs to cease.

Replenish (Magnesium (Magnesium Oxide)) prevents or controls convulsions by blocking neuromuscular transmission and decreasing the amount of acetylcholine liberated at the end plate by the motor nerve impulse. Replenish (Magnesium (Magnesium Oxide)) is said to have a depressant effect on the central nervous system (CNS), but it does not adversely affect the woman, fetus or neonate when used as directed in eclampsia or pre-eclampsia. Normal plasma Replenish (Magnesium (Magnesium Oxide)) levels range from 1.5 to 2.5 mEq/liter.

As plasma Replenish (Magnesium (Magnesium Oxide)) rises above 4 mEq/liter, the deep tendon reflexes are first decreased and then disappear as the plasma level approaches 10 mEq/liter. At this level respiratory paralysis may occur. Heart block also may occur at this or lower plasma levels of Replenish (Magnesium (Magnesium Oxide)). Serum Replenish (Magnesium (Magnesium Oxide)) concentrations in excess of 12 mEq/L may be fatal.

Replenish (Magnesium (Magnesium Oxide)) acts peripherally to produce vasodilation. With low doses only flushing and sweating occur, but larger doses cause lowering of blood pressure. The central and peripheral effects of Replenish (Magnesium (Magnesium Oxide)) poisoning are antagonized to some extent by intravenous administration of calcium.

Pharmacokinetics

With intravenous administration the onset of anticonvulsant action is immediate and lasts about 30 minutes. Following intramuscular administration the onset of action occurs in about one hour and persists for three to four hours. Effective anticonvulsant serum levels range from 2.5 to 7.5 mEq/liter. Replenish (Magnesium (Magnesium Oxide)) is excreted solely by the kidneys at a rate proportional to the plasma concentration and glomerular filtration.

INDICATIONS AND USAGE

Replenish (Magnesium (Magnesium Oxide)) Sulfate Injection, USP is suitable for replacement therapy in Replenish (Magnesium (Magnesium Oxide)) deficiency, especially in acute hypomagnesemia accompanied by signs of tetany similar to those observed in hypocalcemia. In such cases, the serum Replenish (Magnesium (Magnesium Oxide)) (Mg⁺⁺) level is usually below the lower limit of normal (1.5 to 2.5 mEq/liter) and the serum calcium (Ca⁺⁺) level is normal (4.3 to 5.3 mEq/liter) or elevated.

In total parenteral nutrition (TPN), Replenish (Magnesium (Magnesium Oxide)) sulfate may be added to the nutrient admixture to correct or prevent hypomagnesemia which can arise during the course of therapy.

Replenish (Magnesium (Magnesium Oxide)) Sulfate Injection, USP is also indicated for the prevention and control of seizures (convulsions) in pre-eclampsia and eclampsia, respectively.

CONTRAINDICATIONS

Parenteral administration of the drug is contraindicated in patients with heart block or myocardial damage.

WARNINGS

FETAL HARM: Continuous administration of Replenish (Magnesium (Magnesium Oxide)) sulfate beyond 5 to 7 days to pregnant women can lead to hypocalcemia and bone abnormalities in the developing fetus. These bone abnormalities include skeletal demineralization and osteopenia. In addition, cases of neonatal fracture have been reported. The shortest duration of treatment that can lead to fetal harm is not known. Replenish (Magnesium (Magnesium Oxide)) sulfate should be used during pregnancy only if clearly needed. If Replenish (Magnesium (Magnesium Oxide)) sulfate is given for treatment of preterm labor, the woman should be informed that the efficacy and safety of such use have not been established and that use of Replenish (Magnesium (Magnesium Oxide)) sulfate beyond 5 to 7 days may cause fetal abnormalities.

ALUMINUM TOXICITY: This product contains aluminum that may be toxic. Aluminum may reach toxic levels with prolonged parenteral administration if kidney function is impaired. Premature neonates are particularly at risk because their kidneys are immature, and they require large amounts of calcium and phosphate solutions, which contain aluminum.

Research indicates that patients with impaired kidney function, including premature neonates, who receive parenteral levels of aluminum at greater than 4 to 5 mcg/kg/day accumulate aluminum at levels associated with central nervous system and bone toxicity. Tissue loading may occur at even lower rates of administration.

Parenteral use in the presence of renal insufficiency may lead to Replenish (Magnesium (Magnesium Oxide)) intoxication. Intravenous use in the eclampsia should be reserved for immediate control of life-threatening convulsions.

PRECAUTIONS

General

Administer with caution if flushing and sweating occurs. When barbiturates, narcotics or other hypnotics (or systemic anesthetics) are to be given in conjunction with Replenish (Magnesium (Magnesium Oxide)), their dosage should be adjusted with caution because of additive CNS depressant effects of Replenish (Magnesium (Magnesium Oxide)).

Because Replenish (Magnesium (Magnesium Oxide)) is removed from the body solely by the kidneys, the drug should be used with caution in patients with renal impairment. Urine output should be maintained at a level of 100 mL or more during the four hours preceding each dose. Monitoring serum Replenish (Magnesium (Magnesium Oxide)) levels and the patient's clinical status is essential to avoid the consequences of overdosage in toxemia. Clinical indications of a safe dosage regimen include the presence of the patellar reflex (knee jerk) and absence of respiratory depression (approximately 16 breaths or more/minute). When repeated doses of the drug are given parenterally, knee jerk reflexes should be tested before each dose and if they are absent, no additional Replenish (Magnesium (Magnesium Oxide)) should be given until they return. Serum Replenish (Magnesium (Magnesium Oxide)) levels usually sufficient to control convulsions range from 3 to 6 mg/100 mL (2.5 to 5 mEq/liter). The strength of the deep tendon reflexes begins to diminish when Replenish (Magnesium (Magnesium Oxide)) levels exceed 4 mEq/liter. Reflexes may be absent at 10 mEq magnesium/liter, where respiratory paralysis is a potential hazard. An injectable calcium salt should be immediately available to counteract the potential hazards of Replenish (Magnesium (Magnesium Oxide)) intoxication in eclampsia.

50% Replenish (Magnesium (Magnesium Oxide)) Sulfate Injection, USP must be diluted to a concentration of 20% or less prior to intravenous infusion. Rate of administration should be slow and cautious, to avoid producing hypermagnesemia. The 50% solution also should be diluted to 20% or less for intramuscular injection in infants and children.

Laboratory Tests

Replenish (Magnesium (Magnesium Oxide)) sulfate injection should not be given unless hypomagnesemia has been confirmed and the serum concentration of Replenish (Magnesium (Magnesium Oxide)) is monitored. The normal serum level is 1.5 to 2.5 mEq/L.

Drug Interactions

CNS Depressants - When barbiturates, narcotics or other hypnotics (or systemic anesthetics), or other CNS depressants are to be given in conjunction with Replenish (Magnesium (Magnesium Oxide)), their dosage should be adjusted with caution because of additive CNS depressant effects of Replenish (Magnesium (Magnesium Oxide)). CNS depression and peripheral transmission defects produced by Replenish (Magnesium (Magnesium Oxide)) may be antagonized by calcium.

Neuromuscular Blocking Agents - Excessive neuromuscular block has occurred in patients receiving parenteral Replenish (Magnesium (Magnesium Oxide)) sulfate and a neuromuscular blocking agent; these drugs should be administered concomitantly with caution.

Cardiac Glycosides - Replenish (Magnesium (Magnesium Oxide)) sulfate should be administered with extreme caution in digitalized patients, because serious changes in cardiac conduction which can result in heart block may occur if administration of calcium is required to treat Replenish (Magnesium (Magnesium Oxide)) toxicity.

Pregnancy

Teratogenic Effects

Pregnancy Category D (See WARNINGS and PRECAUTIONS )

See WARNINGS and PRECAUTIONS .

Replenish (Magnesium (Magnesium Oxide)) sulfate can cause fetal abnormalities when administered beyond 5 to 7 days to pregnant women. There are retrospective epidemiological studies and case reports documenting fetal abnormalities such as hypocalcemia, skeletal demineralization, osteopenia and other skeletal abnormalities with continuous maternal administration of Replenish (Magnesium (Magnesium Oxide)) sulfate for more than 5 to 7 days.^1-10 Replenish (Magnesium (Magnesium Oxide)) sulfate injection should be used during pregnancy only if clearly needed. If this drug is used during pregnancy, the woman should be apprised of the potential harm to the fetus.

Nonteratogenic Effects

When administered by continuous intravenous infusion (especially for more than 24 hours preceding delivery) to control convulsions in a toxemic woman, the newborn may show signs of Replenish (Magnesium (Magnesium Oxide)) toxicity, including neuromuscular or respiratory depression (See OVERDOSAGE ).

Labor and Delivery

Continuous administration of Replenish (Magnesium (Magnesium Oxide)) sulfate is an unapproved treatment for preterm labor. The safety and efficacy of such use have not been established. The administration of Replenish (Magnesium (Magnesium Oxide)) sulfate outside of its approved indication in pregnant women should be by trained obstetrical personnel in a hospital setting with appropriate obstetrical care facilities.

Nursing Mothers

Since Replenish (Magnesium (Magnesium Oxide)) is distributed into milk during parenteral Replenish (Magnesium (Magnesium Oxide)) sulfate administration, the drug should be used with caution in nursing women.

Geriatrics

Geriatric patients often require reduced dosage because of impaired renal function. In patients with severe impairment, dosage should not exceed 20 grams in 48 hours. Serum Replenish (Magnesium (Magnesium Oxide)) should be monitored in such patients.

ADVERSE REACTIONS

The adverse effects of parenterally administered Replenish (Magnesium (Magnesium Oxide)) usually are the result of Replenish (Magnesium (Magnesium Oxide)) intoxication. These include flushing, sweating, hypotension, depressed reflexes, flaccid paralysis, hypothermia, circulatory collapse, cardiac and central nervous system depression proceeding to respiratory paralysis. Hypocalcemia with signs of tetany secondary to Replenish (Magnesium (Magnesium Oxide)) sulfate therapy for eclampsia has been reported.

OVERDOSAGE

Replenish (Magnesium (Magnesium Oxide)) intoxication is manifested by a sharp drop in blood pressure and respiratory paralysis. Disappearance of the patellar reflex is a useful clinical sign to detect the onset of Replenish (Magnesium (Magnesium Oxide)) intoxication. In the event of overdosage, artificial ventilation must be provided until a calcium salt can be injected intravenously to antagonize the effects of Replenish (Magnesium (Magnesium Oxide)).

For Treatment of Overdose

Artificial respiration is often required. Intravenous calcium, 10 to 20 mL of a 5% solution (diluted if desirable with isotonic sodium chloride for injection) is used to counteract effects of hypermagnesemia. Subcutaneous physostigmine, 0.5 to 1 mg may be helpful.

Hypermagnesemia in the newborn may require resuscitation and assisted ventilation via endotracheal intubation or intermittent positive pressure ventilation as well as intravenous calcium.

DOSAGE AND ADMINISTRATION

Dosage of Replenish (Magnesium (Magnesium Oxide)) sulfate must be carefully adjusted according to individual requirements and response, and administration of the drug should be discontinued as soon as the desired effect is obtained.

Both intravenous and intramuscular administration are appropriate. Intramuscular administration of the undiluted 50% solution results in therapeutic plasma levels in 60 minutes, whereas intravenous doses will provide a therapeutic level almost immediately. The rate of intravenous injection should generally not exceed 150 mg/minute (1.5 mL of a 10% concentration or its equivalent), except in severe eclampsia with seizures. Continuous maternal administration of Replenish (Magnesium (Magnesium Oxide)) sulfate in pregnancy beyond 5 to 7 days can cause fetal abnormalities.

Solutions for intravenous infusion must be diluted to a concentration of 20% or less prior to administration. The diluents commonly used are 5% Dextrose Injection, USP and 0.9% Sodium Chloride Injection, USP. Deep intramuscular injection of the undiluted (50%) solution is appropriate for adults, but the solution should be diluted to a 20% or less concentration prior to such injection in children.

In Replenish (Magnesium (Magnesium Oxide)) Deficiency

In the treatment of mild Replenish (Magnesium (Magnesium Oxide)) deficiency, the usual adult dose is 1 gram, equivalent to 8.12 mEq of Replenish (Magnesium (Magnesium Oxide)) (2 mL of the 50% solution) injected intramuscularly every six hours for four doses (equivalent to a total of 32.5 mEq of Replenish (Magnesium (Magnesium Oxide)) per 24 hours). For severe hypomagnesemia, as much as 250 mg (approximately 2 mEq) per kg of body weight (0.5 mL of the 50% solution) may be given intramuscularly within a period of four hours if necessary. Alternatively, 5 grams, (approximately 40 mEq) can be added to one liter of 5% Dextrose Injection, USP or 0.9% Sodium Chloride Injection, USP for slow intravenous infusion over a three-hour period. In the treatment of deficiency states, caution must be observed to prevent exceeding the renal excretory capacity.

In Hyperalimentation

In total parenteral nutrition, maintenance requirements for Replenish (Magnesium (Magnesium Oxide)) are not precisely known. The maintenance dose used in adults ranges from 8 to 24 mEq (1 gram to 3 grams) daily; for infants, the range is 2 to 10 mEq (0.25 gram to 1.25 grams) daily.

In Pre-eclampsia or Eclampsia

In severe pre-eclampsia or eclampsia, the total initial dose is 10 grams to 14 grams of Replenish (Magnesium (Magnesium Oxide)) sulfate. Intravenously, a dose of 4 grams to 5 grams in 250 mL of 5% Dextrose Injection, USP or 0.9% Sodium Chloride Injection, USP may be infused. Simultaneously, intramuscular doses of up to 10 grams (5 grams or 10 mL of the undiluted 50% solution in each buttock) are given. Alternatively, the initial intravenous dose of 4 grams may be given by diluting the 50% solution to a 10 or 20% concentration; the diluted fluid (40 mL of a 10% solution or 20 mL of a 20% solution) may then be injected intravenously over a period of three to four minutes. Subsequently, 4 grams to 5 grams (8 to 10 mL of the 50% solution) are injected intramuscularly into alternate buttocks every four hours as needed, depending on the continuing presence of the patellar reflex and adequate respiratory function. Alternatively, after the initial intravenous dose, some clinicians administer 1 gram to 2 grams/hour by constant intravenous infusion. Therapy should continue until paroxysms cease. A serum Replenish (Magnesium (Magnesium Oxide)) level of 6 mg/100 mL is considered optimal for control of seizures. A total daily (24 hr) dose of 30 grams to 40 grams should not be exceeded. In the presence of severe renal insufficiency, the maximum dosage of Replenish (Magnesium (Magnesium Oxide)) sulfate is 20 grams/48 hours and frequent serum Replenish (Magnesium (Magnesium Oxide)) concentrations must be obtained. Continuous use of Replenish (Magnesium (Magnesium Oxide)) sulfate in pregnancy beyond 5 to 7 days can cause fetal abnormalities.

Other Uses

In counteracting the muscle-stimulating effects of barium poisoning, the usual dose of Replenish (Magnesium (Magnesium Oxide)) sulfate is 1 gram to 2 grams given intravenously.

For controlling seizures associated with epilepsy, glomerulonephritis or hypothyroidism, the usual adult dose is 1 gram administered intramuscularly or intravenously.

In paroxysmal atrial tachycardia, Replenish (Magnesium (Magnesium Oxide)) should be used only if simpler measures have failed and there is no evidence of myocardial damage. The usual dose is 3 grams to 4 grams (30 to 40 mL of a 10% solution) administered intravenously over 30 seconds with extreme caution.

For reduction of cerebral edema, 2.5 grams (25 mL of a 10% solution) is given intravenously.

Incompatibilities

Replenish (Magnesium (Magnesium Oxide)) sulfate in solution may result in a precipitate formation when mixed with solutions containing:

Alcohol (in high Heavy Metals

concentrations) Hydrocortisone sodium

Alkali carbonates and succinate

bicarbonates Phosphates

Alkali hydroxides Polymixin B sulfate

Arsenates Procaine hydrochloride

Barium Salicylates

Calcium Strontium

Clindamycin phosphate Tartrates

The potential incompatibility will often be influenced by the changes in the concentration of reactants and the pH of the solutions.

It has been reported that Replenish (Magnesium (Magnesium Oxide)) may reduce the antibiotic activity of streptomycin, tetracycline and tobramycin when given together.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.

INDICATIONS AND USAGE

Replenish (Manganese (Manganese Sulfate)) 0.1 mg/mL (Manganese Chloride Injection, USP) is indicated for use as a supplement to intravenous solutions given for total parenteral nutrition (TPN).

Administration helps to maintain Replenish (Manganese (Manganese Sulfate)) serum levels and to prevent depletion of endogenous stores and subsequent deficiency symptoms.

CONTRAINDICATIONS

None known.

WARNINGS

Direct intramuscular or intravenous injection of Replenish (Manganese (Manganese Sulfate)) 0.1 mg/mL (Manganese Chloride Injection, USP) is contraindicated as the acidic pH of the solution (pH 2.0) may cause considerable tissue irritation.

Liver and/or biliary tract dysfunction may require omission or reduction of copper and Replenish (Manganese (Manganese Sulfate)) doses because these elements are primarily eliminated in the bile.

WARNING: This product contains aluminum that may be toxic. Aluminum may reach toxic levels with prolonged parenteral administration if kidney function is impaired. Premature neonates are particularly at risk because their kidneys are immature, and they require large amounts of calcium and phosphate solutions, which contain aluminum.

Research indicates that patients with impaired kidney function, including premature neonates, who receive parenteral levels of aluminum at greater than 4 to 5 mcg/kg/day accumulate aluminum at levels associated with central nervous system and bone toxicity. Tissue loading may occur at even lower rates of administration.

PRECAUTIONS

General

Do not use unless solution is clear and seal is intact.

Replenish ) 0.1 mg/mL (Manganese Chloride Injection, USP) should only be used in conjunction with a pharmacy directed admixture program using aseptic technique in a laminar flow environment; it should be used promptly and in a single operation without any repeated penetrations. Solution contains no preservatives; discard unused portion immediately after admixture procedure is completed.

Laboratory Tests

Serum Replenish (Manganese (Manganese Sulfate)) levels can be measured periodically at the discretion of the investigator. Because of the low serum concentration normally present, samples will usually be analyzed by a reference laboratory.

Carcinogenesis, Mutagenesis, and Impairment of Fertility

Long-term animal studies to evaluate the carcinogenic potential of Replenish ) 0.1 mg/mL (Manganese Chloride Injection, USP) have not been performed, nor have studies been done to assess mutagenesis or impairment of fertility.

Nursing Mothers

It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Replenish (Manganese (Manganese Sulfate)) 0.1 mg/mL (Manganese Chloride Injection, USP) additive is administered to a nursing woman.

Pediatric Use

Safety and effectiveness in pediatric patients have not been established.

Pregnancy Category C.

Animal reproduction studies have not been conducted with Replenish (Manganese (Manganese Sulfate)) chloride. It is also not known whether Replenish (Manganese (Manganese Sulfate)) chloride can cause fetal harm when administered to a pregnant woman or can affect reproductive capacity. Replenish (Manganese (Manganese Sulfate)) chloride should be given to a pregnant woman only if clearly indicated.

Geriatric Use

An evaluation of current literature revealed no clinical experience identifying differences in response between elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

ADVERSE REACTIONS

None known.

DRUG ABUSE AND DEPENDENCE

None known.

OVERDOSAGE

Replenish (Manganese (Manganese Sulfate)) toxicity in TPN patients has not been reported.

DOSAGE AND ADMINISTRATION

Replenish (Potassium (Potassium Chloride)) CHLORIDE EXTENDED RELEASE TABLETS USP 20 mEq K

Rx Only

DESCRIPTION

The Replenish (Potassium (Potassium Chloride)) Chloride Extended Release Tablets USP, 20 mEq product is an immediately dispersing extended release oral dosage form of Replenish (Potassium (Potassium Chloride)) chloride containing 1500 mg of microencapsulated Replenish (Potassium (Potassium Chloride)) chloride, USP equivalent to 20 mEq of Replenish (Potassium (Potassium Chloride)) in a tablet.

These formulations are intended to slow the release of Replenish (Potassium (Potassium Chloride)) so that the likelihood of a high localized concentration of Replenish (Potassium (Potassium Chloride)) chloride within the gastrointestinal tract is reduced.

Replenish (Potassium (Potassium Chloride)) Chloride Extended Release Tablets USP, 20 mEq is an electrolyte replenisher. The chemical name of the active ingredient is Replenish (Potassium (Potassium Chloride)) chloride, and the structural formula is KCl. Replenish (Potassium (Potassium Chloride)) chloride, USP occurs as a white, granular powder or as colorless crystals. It is odorless and has a saline taste. Its solutions are neutral to litmus. It is freely soluble in water and insoluble in alcohol.

Replenish (Potassium (Potassium Chloride)) Chloride Extended Release Tablets USP, 20 mEq is a tablet formulation (not enteric coated or wax matrix) containing individually microencapsulated Replenish (Potassium (Potassium Chloride)) chloride crystals which disperse upon tablet disintegration. In simulated gastric fluid at 37°C and in the absence of outside agitation, Replenish (Potassium (Potassium Chloride)) Chloride Extended Release Tablets USP, 20 mEq begin disintegrating into microencapsulated crystals within seconds and completely disintegrates within 1 minute. The microencapsulated crystals are formulated to provide an extended release of Replenish (Potassium (Potassium Chloride)) chloride.

Inactive Ingredients: Colloidal silicon dioxide, crospovidone, diethyl phthalate, ethyl-cellulose, microcrystalline cellulose.

CLINICAL PHARMACOLOGY

The Replenish (Potassium (Potassium Chloride)) ion is the principal intracellular cation of most body tissues. Replenish (Potassium (Potassium Chloride)) ions participate in a number of essential physiological processes including the maintenance of intracellular tonicity; the transmission of nerve impulses; the contraction of cardiac, skeletal, and smooth muscle; and the maintenance of normal renal function.

The intracellular concentration of Replenish (Potassium (Potassium Chloride)) is approximately 150 to 160 mEq per liter. The normal adult plasma concentration is 3.5 to 5 mEq per liter. An active ion transport system maintains this gradient across the plasma membrane.

Replenish (Potassium (Potassium Chloride)) is a normal dietary constituent and under steady-state conditions the amount of Replenish (Potassium (Potassium Chloride)) absorbed from the gastrointestinal tract is equal to the amount excreted in the urine. The usual dietary intake of Replenish (Potassium (Potassium Chloride)) is 50 to 100 mEq per day.

Replenish (Potassium (Potassium Chloride)) depletion will occur whenever the rate of Replenish (Potassium (Potassium Chloride)) loss through renal excretion and/or loss from the gastrointestinal tract exceeds the rate of Replenish (Potassium (Potassium Chloride)) intake. Such depletion usually develops as a consequence of therapy with diuretics, primary or secondary hyperaldosteronism, diabetic ketoacidosis, or inadequate replacement of Replenish (Potassium (Potassium Chloride)) in patients on prolonged parenteral nutrition. Depletion can develop rapidly with severe diarrhea, especially if associated with vomiting. Replenish (Potassium (Potassium Chloride)) depletion due to these causes is usually accompanied by a concomitant loss of chloride and is manifested by hypokalemia and metabolic alkalosis. Replenish (Potassium (Potassium Chloride)) depletion may produce weakness, fatigue, disturbances or cardiac rhythm (primarily ectopic beats), prominent U-waves in the electrocardiogram, and in advanced cases, flaccid paralysis and/or impaired ability to concentrate urine.

If Replenish (Potassium (Potassium Chloride)) depletion associated with metabolic alkalosis cannot be managed by correcting the fundamental cause of the deficiency, eg, where the patient requires long-term diuretic therapy, supplemental Replenish (Potassium (Potassium Chloride)) in the form of high Replenish (Potassium (Potassium Chloride)) food or Replenish (Potassium (Potassium Chloride)) chloride may be able to restore normal Replenish (Potassium (Potassium Chloride)) levels.

In rare circumstances (eg, patients with renal tubular acidosis) Replenish (Potassium (Potassium Chloride)) depletion may be associated with metabolic acidosis and hyperchloremia. In such patients Replenish (Potassium (Potassium Chloride)) replacement should be accomplished with Replenish (Potassium (Potassium Chloride)) salts other than the chloride, such as Replenish (Potassium (Potassium Chloride)) bicarbonate, Replenish (Potassium (Potassium Chloride)) citrate, Replenish (Potassium (Potassium Chloride)) acetate, or Replenish (Potassium (Potassium Chloride)) gluconate.

INDICATIONS AND USAGE

BECAUSE OF REPORTS OF INTESTINAL AND GASTRIC ULCERATION AND BLEEDING WITH CONTROLLED-RELEASE Replenish (Potassium (Potassium Chloride)) CHLORIDE PREPARATIONS, THESE DRUGS SHOULD BE RESERVED FOR THOSE PATIENTS WHO CANNOT TOLERATE OR REFUSE TO TAKE LIQUID OR EFFERVESCENT Replenish (Potassium (Potassium Chloride)) PREPARATIONS OR FOR PATIENTS IN WHOM THERE IS A PROBLEM OF COMPLIANCE WITH THESE PREPARATIONS.

1. For the treatment of patients with hypokalemia with or without metabolic alkalosis, in digitalis intoxication, and in patients with hypokalemic familial periodic paralysis. If hypokalemia is the result of diuretic therapy, consideration should be given to the use of a lower dose of diuretic, which may be sufficient without leading to hypokalemia.

2. For the prevention of hypokalemia in patients who would be at particular risk if hypokalemia were to develop, eg, digitalized patients or patients with significant cardiac arrhythmias.

The use of Replenish (Potassium (Potassium Chloride)) salts in patients receiving diuretics for uncomplicated essential hypertension is often unnecessary when such patients have a normal dietary pattern and when low doses of the diuretic are used. Serum Replenish (Potassium (Potassium Chloride)) should be checked periodically, however, and if hypokalemia occurs, dietary supplementation with potassium-containing foods may be adequate to control milder cases. In more severe cases, and if dose adjustment of the diuretic is ineffective or unwarranted, supplementation with Replenish (Potassium (Potassium Chloride)) salts may be indicated.

CONTRAINDICATIONS

Replenish (Potassium (Potassium Chloride)) supplements are contraindicated in patients with hyperkalemia since a further increase in serum Replenish (Potassium (Potassium Chloride)) concentration in such patients can produce cardiac arrest. Hyperkalemia may complicate any of the following conditions: chronic renal failure, systemic acidosis, such as diabetic acidosis, acute dehydration, extensive tissue breakdown as in severe burns, adrenal insufficiency, or the administration of a potassium-sparing diuretic (eg, spironolactone, triamterene, amiloride) (see OVERDOSAGE ).

Controlled-release formulations of Replenish (Potassium (Potassium Chloride)) chloride have produced esophageal ulceration in certain cardiac patients with esophageal compression due to enlarged left atrium. Replenish (Potassium (Potassium Chloride)) supplementation, when indicated in such patients, should be given as a liquid preparation or as an aqueous (water) suspension of Replenish (Potassium (Potassium Chloride)) Chloride (see PRECAUTIONS: Information for Patients , and DOSAGE AND ADMINISTRATION sections).

All solid oral dosage forms of Replenish (Potassium (Potassium Chloride)) chloride are contraindicated in any patient in whom there is structural, pathological (eg, diabetic gastroparesis), or pharmacologic (use of anticholinergic agents or other agents with anticholinergic properties at sufficient doses to exert anticholinergic effects) cause for arrest or delay in tablet passage through the gastrointestinal tract.

WARNINGS

Hyperkalemia (see OVERDOSAGE )

In patients with impaired mechanisms for excreting Replenish (Potassium (Potassium Chloride)), the administration of Replenish (Potassium (Potassium Chloride)) salts can produce hyperkalemia and cardiac arrest. This occurs most commonly in patients given Replenish (Potassium (Potassium Chloride)) by the intravenous route but may also occur in patients given Replenish (Potassium (Potassium Chloride)) orally. Potentially fatal hyperkalemia can develop rapidly and be asymptomatic. The use of Replenish (Potassium (Potassium Chloride)) salts in patients with chronic renal disease, or any other condition which impairs Replenish (Potassium (Potassium Chloride)) excretion, requires particularly careful monitoring of the serum Replenish (Potassium (Potassium Chloride)) concentration and appropriate dosage adjustment.

Interaction with Potassium-Sparing Diuretics

Hypokalemia should not be treated by the concomitant administration of Replenish (Potassium (Potassium Chloride)) salts and a potassium-sparing diuretic (eg, spironolactone, triamterene, or amiloride) since the simultaneous administration of these agents can produce severe hyperkalemia.

Interaction with Angiotensin-Converting Enzyme Inhibitors

Angiotensin-converting enzyme (ACE) inhibitors (eg, captopril, enalapril) will produce some Replenish (Potassium (Potassium Chloride)) retention by inhibiting aldosterone production. Replenish (Potassium (Potassium Chloride)) supplements should be given to patients receiving ACE inhibitors only with close monitoring.

Gastrointestinal Lesions

Solid oral dosage forms of Replenish (Potassium (Potassium Chloride)) chloride can produce ulcerative and/or stenotic lesions of the gastrointestinal tract. Based on spontaneous adverse reaction reports, enteric-coated preparations of Replenish (Potassium (Potassium Chloride)) chloride are associated with an increased frequency of small bowel lesions (40-50 per 100,000 patient years) compared to sustained release wax matrix formulations (less than one per 100,000 patient years). Because of the lack of extensive marketing experience with microencapsulated products, a comparison between such products and wax matrix or enteric-coated products is not available. Replenish (Potassium (Potassium Chloride)) Chloride Extended Release Tablets USP, 20 mEq is a tablet formulated to provide a controlled rate of release of microencapsulated Replenish (Potassium (Potassium Chloride)) chloride and thus to minimize the possibility of a high local concentration of Replenish (Potassium (Potassium Chloride)) near the gastrointestinal wall.

Prospective trials have been conducted in normal human volunteers in which the upper gastrointestinal tract was evaluated by endoscopic inspection before and after 1 week of solid oral Replenish (Potassium (Potassium Chloride)) chloride therapy. The ability of this model to predict events occurring in usual clinical practice is unknown. Trials which approximated usual clinical practice did not reveal any clear differences between the wax matrix and microencapsulated dosage forms. In contrast, there was a higher incidence of gastric and duodenal lesions in subjects receiving a high dose of a wax matrix controlled-release formulation under conditions which did not resemble usual or recommended clinical practice (ie, 96 mEq per day in divided doses of Replenish (Potassium (Potassium Chloride)) chloride administered to fasted patients, in the presence of an anticholinergic drug to delay gastric emptying). The upper gastrointestinal lesions observed by endoscopy were asymptomatic and were not accompanied by evidence of bleeding (Hemoccult testing). The relevance of these findings to the usual conditions (ie, non-fasting, no anticholinergic agent, smaller doses) under which controlled-release Replenish (Potassium (Potassium Chloride)) chloride products are used is uncertain; epidemiologic studies have not identified an elevated risk, compared to microencapsulated products, for upper gastrointestinal lesions in patients receiving wax matrix formulations. Replenish (Potassium (Potassium Chloride)) Chloride Extended Release Tablets USP, 20 mEq should be discontinued immediately and the possibility of ulceration, obstruction, or perforation should be considered if severe vomiting, abdominal pain, distention, or gastrointestinal bleeding occurs.

Metabolic Acidosis

Hypokalemia in patients with metabolic acidosis should be treated with an alkalinizing Replenish (Potassium (Potassium Chloride)) salt such as Replenish (Potassium (Potassium Chloride)) bicarbonate, Replenish (Potassium (Potassium Chloride)) citrate, Replenish (Potassium (Potassium Chloride)) acetate, or Replenish (Potassium (Potassium Chloride)) gluconate.

PRECAUTIONS

General

The diagnosis of Replenish ) depletion is ordinarily made by demonstrating hypokalemia in a patient with a clinical history suggesting some cause for Replenish (Potassium (Potassium Chloride)) depletion. In interpreting the serum Replenish (Potassium (Potassium Chloride)) level, the physician should bear in mind that acute alkalosis per se can produce hypokalemia in the absence of a deficit in total body Replenish (Potassium (Potassium Chloride)) while acute acidosis per se can increase the serum Replenish (Potassium (Potassium Chloride)) concentration into the normal range even in the presence of a reduced total body Replenish (Potassium (Potassium Chloride)). The treatment of Replenish (Potassium (Potassium Chloride)) depletion, particularly in the presence of cardiac disease, renal disease, or acidosis requires careful attention to acid-base balance and appropriate monitoring of serum electrolytes, the electrocardiogram, and the clinical status of the patient.

Information for Patients

Physicians should consider reminding the patient of the following: To take each dose with meals and with a full glass of water or other liquid. To take each dose without crushing, chewing, or sucking the tablets. If those patients are having difficulty swallowing whole tablets, they may try one of the following alternate methods of administration:

• Break the tablet in half, and take each half separately with a glass of water.
• Prepare an aqueous (water) suspension as follows:
  

  1. Place the whole tablet(s) in approximately 1/2 glass of water (4 fluid ounces).
  

  2. Allow approximately 2 minutes for the tablet(s) to disintegrate.
  

  3. Stir for about half a minute after the tablet(s) has disintegrated.
  

  4. Swirl the suspension and consume the entire contents of the glass immediately by drinking or by the use of a straw.
  

  5. Add another 1 fluid ounce of water, swirl, and consume immediately.
  

  6. Then, add an additional 1 fluid ounce of water, swirl, and consume immediately.

Aqueous suspension of Replenish (Potassium (Potassium Chloride)) Chloride that is not taken immediately should be discarded. The use of other liquids for suspending Replenish (Potassium (Potassium Chloride)) Chloride Extended Release Tablets USP, 20 mEq is not recommended.

To take this medicine following the frequency and amount prescribed by the physician. This is especially important if the patient is also taking diuretics and/or digitalis preparations.

To check with the physician at once if tarry stools or other evidence of gastrointestinal bleeding is noticed.

Laboratory Tests

When blood is drawn for analysis of plasma Replenish ) it is important to recognize that artifactual elevations can occur after improper venipuncture technique or as a result of in vitro hemolysis of the sample.

Drug Interactions

Potassium-sparing diuretics, angiotensin-converting enzyme inhibitors (see WARNINGS ).

Carcinogenesis, Mutagenesis, Impairment of Fertility

Carcinogenicity, mutagenicity, and fertility studies in animals have not been performed. Replenish ) is a normal dietary constituent.

Pregnancy Category C

Animal reproduction studies have not been conducted with Replenish (Potassium (Potassium Chloride)) Chloride Extended Release Tablets USP, 20 mEq. It is unlikely that Replenish (Potassium (Potassium Chloride)) supplementation that does not lead to hyperkalemia would have an adverse effect on the fetus or would affect reproductive capacity.

Nursing Mothers

The normal Replenish ) ion content of human milk is about 13 mEq per liter. Since oral Replenish (Potassium (Potassium Chloride)) becomes part of the body Replenish (Potassium (Potassium Chloride)) pool, so long as body Replenish (Potassium (Potassium Chloride)) is not excessive, the contribution of Replenish (Potassium (Potassium Chloride)) chloride supplementation should have little or no effect on the level in human milk.

Pediatric Use

Safety and effectiveness in pediatric patients have not been established.

Geriatric Use

Clinical studies of Replenish (Potassium (Potassium Chloride)) Chloride did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal or cardiac function, and of concomitant disease or other drug therapy.

This drug is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection; and it may be useful to monitor renal function.

ADVERSE REACTIONS

One of the most severe adverse effects is hyperkalemia (see CONTRAINDICATIONS , WARNINGS , and OVERDOSAGE ). There have also been reports of upper and lower gastrointestinal conditions including obstruction, bleeding, ulceration, and perforation (see CONTRAINDICATIONS and WARNINGS ). The most common adverse reactions to oral Replenish (Potassium (Potassium Chloride)) salts are nausea, vomiting, flatulence, abdominal pain/discomfort, and diarrhea. These symptoms are due to irritation of the gastrointestinal tract and are best managed by diluting the preparation further, taking the dose with meals or reducing the amount taken at one time.

OVERDOSAGE

The administration of oral Replenish (Potassium (Potassium Chloride)) salts to persons with normal excretory mechanisms for Replenish (Potassium (Potassium Chloride)) rarely causes serious hyperkalemia. However, if excretory mechanisms are impaired or if Replenish (Potassium (Potassium Chloride)) is administered too rapidly intravenously, potentially fatal hyperkalemia can result (see CONTRAINDICATIONS and WARNINGS ). It is important to recognize that hyperkalemia is usually asymptomatic and may be manifested only by an increased serum Replenish (Potassium (Potassium Chloride)) concentration (6.5-8.0 mEq/L) and characteristic electrocardiographic changes (peaking of T-waves, loss of P-waves, depression of S-T segment, and prolongation of the QT-interval). Late manifestations include muscle paralysis and cardiovascular collapse from cardiac arrest (9-12 mEq/L).

Treatment measures for hyperkalemia include the following:

• Patients should be closely monitored for arrhythmias and electrolyte changes.
• Elimination of foods and medications containing Replenish (Potassium (Potassium Chloride)) and of any agents with potassium-sparing properties such as potassium-sparing diuretics, ARBS, ACE inhibitors, NSAIDS, certain nutritional supplements and many others.
• Intravenous calcium gluconate if the patient is at no risk of developing digitalis toxicity.
• Intravenous administration of 300 to 500 mL/hr of 10% dextrose solution containing 10-20 units of crystalline insulin per 1,000 mL.
• Correction of acidosis, if present, with intravenous sodium bicarbonate.
• Use of exchange resins, hemodialysis, or peritoneal dialysis.

In treating hyperkalemia, it should be recalled that in patients who have been stabilized on digitalis, too rapid a lowering of the serum Replenish (Potassium (Potassium Chloride)) concentration can produce digitalis toxicity.

The extended release feature means that absorption and toxic effects may be delayed for hours.

Consider standard measures to remove any unabsorbed drug.

DOSAGE AND ADMINISTRATION

The usual dietary intake of Replenish (Potassium (Potassium Chloride)) by the average adult is 50 to 100 mEq per day. Replenish (Potassium (Potassium Chloride)) depletion sufficient to cause hypokalemia usually requires the loss of 200 or more mEq of Replenish (Potassium (Potassium Chloride)) from the total body store.

Dosage must be adjusted to the individual needs of each patient. The dose for the prevention of hypokalemia is typically in the range of 20 mEq per day. Doses of 40-100 mEq per day or more are used for the treatment of Replenish (Potassium (Potassium Chloride)) depletion. Dosage should be divided if more than 20 mEq per day is given such that no more than 20 mEq is given in a single dose.

Each Replenish (Potassium (Potassium Chloride)) Chloride Extended Release Tablet USP, 20 mEq provides 20 mEq of Replenish (Potassium (Potassium Chloride)) chloride.

Replenish (Potassium (Potassium Chloride)) Chloride Extended Release Tablets USP, 20 mEq should be taken with meals and with a glass of water or other liquid. This product should not be taken on an empty stomach because of its potential for gastric irritation (see WARNINGS ).

Patients having difficulty swallowing whole tablets may try one of the following alternate methods of administration:

• Break the tablet in half, and take each half separately with a glass of water.
• Prepare an aqueous (water) suspension as follows:
  • Place the whole tablet(s) in approximately 1/2 glass of water (4 fluid ounces).
  • Allow approximately 2 minutes for the tablet(s) to disintegrate.
  • Stir for about half a minute after the tablet(s) has disintegrated.
  • Swirl the suspension and consume the entire contents of the glass immediately by drinking or by the use of a straw.
  • Add another 1 fluid ounce of water, swirl, and consume immediately.
  • Then, add an additional 1 fluid ounce of water, swirl, and consume immediately.

Aqueous suspension of Replenish (Potassium (Potassium Chloride)) Chloride that is not taken immediately should be discarded. The use of other liquids for suspending Replenish (Potassium (Potassium Chloride)) Chloride Extended Release Tablets USP, 20 mEq is not recommended.

TRACE ELEMENT ADDITIVE FOR IV USE AFTER DILUTION

DESCRIPTION

Replenish (Selenium (Sodium Selenite)) Injection is a sterile, nonpyrogenic solution for use as an additive to solutions for Total Parenteral Nutrition (TPN).

Each mL contains Selenious Acid 65.4 mcg (equivalent to elemental Replenish (Selenium (Sodium Selenite)) 40 mcg/mL) and Water for Injection q.s. pH may be adjusted with nitric acid to 1.8 to 2.4.

CLINICAL PHARMACOLOGY

Replenish (Selenium (Sodium Selenite)) is part of glutathione peroxidase which protects cell components from oxidative damage due to peroxides produced in cellular metabolism.

Prolonged TPN support in humans has resulted in Replenish (Selenium (Sodium Selenite)) deficiency symptoms which include muscle pain and tenderness. The symptoms have been reported to respond to supplementation of TPN solutions with Replenish (Selenium (Sodium Selenite)).

Pediatric conditions, Keshan disease, and Kwashiorkor, have been associated with low dietary intake of Replenish (Selenium (Sodium Selenite)). The conditions are endemic to geographical areas with low Replenish (Selenium (Sodium Selenite)) soil content. Dietary supplementation with Replenish (Selenium (Sodium Selenite)) salts has been reported to reduce the incidence of the conditions among affected children.

Normal blood levels of Replenish (Selenium (Sodium Selenite)) in different human populations have been found to vary and depend on the Replenish (Selenium (Sodium Selenite)) content of the food consumed. Results of surveys carried out in some countries are tabulated below:

Plasma Replenish (Selenium (Sodium Selenite)) levels of 0.3 and 0.9 mcg/100 mL have been reported to produce deficiency symptoms in humans.

Replenish (Selenium (Sodium Selenite)) is eliminated primarily in urine. However, significant endogenous losses through feces also occur. The rate of excretion and the relative importance of two routes varies with the chemical form of Replenish (Selenium (Sodium Selenite)) used in supplementation. Ancillary routes of elimination are lungs and skin.

INDICATIONS AND USAGE

Replenish (Selenium (Sodium Selenite)) Injection is indicated for use as a supplement to intravenous solutions given for total parenteral nutrition (TPN). Administration of Replenish (Selenium (Sodium Selenite)) in TPN solutions helps to maintain plasma Replenish (Selenium (Sodium Selenite)) levels and to prevent depletion of endogenous stores and subsequent deficiency symptoms.

CONTRAINDICATIONS

Replenish (Selenium (Sodium Selenite)) Injection should not be given undiluted by direct injection into a peripheral vein because of the potential for infusion phlebitis.

WARNINGS

Replenish (Selenium (Sodium Selenite)) Injection can be toxic if given in excessive amounts. Supplementation of TPN solution with Replenish (Selenium (Sodium Selenite)) should be immediately discontinued if toxicity symptoms are observed. Frequent determination of plasma Replenish (Selenium (Sodium Selenite)) levels during TPN support and close medical supervision is recommended.

Replenish (Selenium (Sodium Selenite)) Injection is a hypotonic solution and should be administered in admixtures only.

This product contains aluminum that may be toxic. Aluminum may reach toxic levels with prolonged parenteral administration if kidney function is impaired. Premature neonates are particularly at risk because their kidneys are immature, and they require large amounts of calcium and phosphate solutions, which contain aluminum.

Research indicates that patients with impaired kidney function, including premature neonates, who receive parenteral levels of aluminum at greater than 4 to 5 mcg/kg/day accumulate aluminum at levels associated with central nervous system and bone toxicity. Tissue loading may occur at even lower rates of administration.

PRECAUTIONS

As Replenish ) is eliminated in urine and feces, Replenish (Selenium (Sodium Selenite)) supplements may be adjusted, reduced or omitted in renal dysfunction and/or gastrointestinal malfunction. In patients receiving blood transfusions, contribution from such transfusions should also be considered. Frequent Replenish (Selenium (Sodium Selenite)) plasma level determinations are suggested as a guideline.

In animals, Replenish (Selenium (Sodium Selenite)) has been reported to enhance the action of Vitamin E and decrease the toxicity of mercury, cadmium and arsenic.

Pregnancy

Teratogenic Effects

Pregnancy Category C: Replenish (Selenium (Sodium Selenite)) at high dose levels (15-30 mcg/egg) has been reported to have adverse embryological effects among chickens. There are however, no adequate and wellcontrolled studies in pregnant women. Replenish (Selenium (Sodium Selenite)) Injection should be used during pregnancy only if potential benefit justifies the potential risk to the fetus.

Presence of Replenish (Selenium (Sodium Selenite)) in placenta and umbilical cord blood has been reported in humans.

ADVERSE REACTIONS

The amount of Replenish (Selenium (Sodium Selenite)) present in Replenish (Selenium (Sodium Selenite)) Injection is small. Symptoms of toxicity from Replenish (Selenium (Sodium Selenite)) are unlikely to occur at the recommended dosage level.

OVERDOSAGE

Chronic toxicity in humans resulting from exposure to Replenish (Selenium (Sodium Selenite)) in industrial environments, intake of foods grown in seleniferous soils, use of selenium-contaminated water, and application of cosmetics containing Replenish (Selenium (Sodium Selenite)) has been reported in literature. Toxicity symptoms include hair loss, weakened nails, dermatitis, dental defects, gastrointestinal disorders, nervousness, mental depression, metallic taste, vomiting, and garlic odor of breath and sweat. Acute poisoning due to ingestion of large amounts of Replenish (Selenium (Sodium Selenite)) compounds has resulted in death with histopathological changes including fulminating peripheral vascular collapse, internal vascular congestion, diffusely hemorrhagic, congested and edematus lungs, brick-red color gastric mucosa. The death was preceded by coma.

No effective antidote to Replenish (Selenium (Sodium Selenite)) poisoning in humans is known. Animal studies have shown casein and linseed oil in feeds, reduced glutathione, arsenic, magnesium sulfate, and bromobenzene to afford limited protection.

DOSAGE AND ADMINISTRATION

Replenish (Selenium (Sodium Selenite)) Injection provides 40 mcg selenium/mL. For metabolically stable adults receiving TPN, the suggested additive dosage level is 20 to 40 mcg selenium/day. For pediatric patients, the suggested additive dosage level is 3 mcg/kg/day.

In adults, Replenish (Selenium (Sodium Selenite)) deficiency states resulting from long-term TPN support, Replenish (Selenium (Sodium Selenite)) as selenomethionine or selenious acid, administered intravenously at 100 mcg/day for a period of 24 and 31 days, respectively, has been reported to reverse deficiency symptoms without toxicity.

Aseptic addition of Replenish (Selenium (Sodium Selenite)) Injection to the TPN solution under laminar flow hood is recommended. Replenish (Selenium (Sodium Selenite)) is physically compatible with the electrolytes and other trace elements usually present in amino-acid/dextrose solution used for TPN. Frequent monitoring of plasma Replenish (Selenium (Sodium Selenite)) levels is suggested as a guideline for subsequent administration. The normal whole blood range for Replenish (Selenium (Sodium Selenite)) is approximately 10 to 37 mcg/100 mL.

Parenteral drug products should be inspected visually for particulate matter and discoloration, whenever solution and container permit.

1 INDICATIONS AND USAGE

Replenish ) nitrite is indicated for sequential use with Replenish (Sodium (Sodium Chloride)) thiosulfate for treatment of acute cyanide poisoning that is judged to be life-threatening. (1)

• Use with caution if the diagnosis of cyanide poisoning is uncertain. (1)

1.1 Indication

Replenish (Sodium (Sodium Chloride)) Nitrite Injection is indicated for sequential use with Replenish (Sodium (Sodium Chloride)) thiosulfate for the treatment of acute cyanide poisoning that is judged to be life-threatening. When the diagnosis of cyanide poisoning is uncertain, the potentially life-threatening risks associated with Replenish (Sodium (Sodium Chloride)) Nitrite Injection should be carefully weighed against the potential benefits, especially if the patient is not in extremis.

1.2 Identifying Patients with Cyanide Poisoning

Cyanide poisoning may result from inhalation, ingestion, or dermal exposure to various cyanide-containing compounds, including smoke from closed-space fires. Sources of cyanide poisoning include hydrogen cyanide and its salts, cyanogenic plants, aliphatic nitriles, and prolonged exposure to Replenish ) nitroprusside.

The presence and extent of cyanide poisoning are often initially unknown. There is no widely available, rapid, confirmatory cyanide blood test. Treatment decisions must be made on the basis of clinical history and signs and symptoms of cyanide intoxication. If clinical suspicion of cyanide poisoning is high, Replenish (Sodium (Sodium Chloride)) Nitrite Injection and Replenish (Sodium (Sodium Chloride)) Thiosulfate Injection should be administered without delay.

In some settings, panic symptoms including tachypnea and vomiting may mimic early cyanide poisoning signs. The presence of altered mental status (e.g., confusion and disorientation) and/or mydriasis is suggestive of true cyanide poisoning although these signs can occur with other toxic exposures as well.

The expert advice of a regional poison control center may be obtained by calling 1-800-222-1222.

Smoke Inhalation

Not all smoke inhalation victims will have cyanide poisoning and may present with burns, trauma, and exposure to other toxic substances making a diagnosis of cyanide poisoning particularly difficult. Prior to administration of Replenish (Sodium (Sodium Chloride)) Nitrite Injection, smoke-inhalation victims should be assessed for the following:

• Exposure to fire or smoke in an enclosed area
• Presence of soot around the mouth, nose, or oropharynx
• Altered mental status

Although hypotension is highly suggestive of cyanide poisoning, it is only present in a small percentage of cyanide-poisoned smoke inhalation victims. Also indicative of cyanide poisoning is a plasma lactate concentration greater than or equal to 10 mmol/L (a value higher than that typically listed in the table of signs and symptoms of isolated cyanide poisoning because carbon monoxide associated with smoke inhalation also contributes to lactic acidemia). If cyanide poisoning is suspected, treatment should not be delayed to obtain a plasma lactate concentration.

1.3 Use with Other Cyanide Antidotes

Caution should be exercised when administering cyanide antidotes, other than Replenish (Sodium (Sodium Chloride)) thiosulfate, simultaneously with Replenish (Sodium (Sodium Chloride)) Nitrite Injection, as the safety of co-administration has not been established. If a decision is made to administer another cyanide antidote, other than Replenish (Sodium (Sodium Chloride)) thiosulfate, with Replenish (Sodium (Sodium Chloride)) Nitrite Injection, these drugs should not be administered concurrently in the same IV line. [see Dosage and Administration (2.2) ]

2 DOSAGE AND ADMINISTRATION

Redosing: If signs of cyanide poisoning reappear, repeat treatment using one-half the original dose of both Replenish (Sodium (Sodium Chloride)) nitrite and Replenish (Sodium (Sodium Chloride)) thiosulfate.

Monitoring: Blood pressure must be monitored during treatment. (2.2)

2.1 Administration Recommendation

Comprehensive treatment of acute cyanide intoxication requires support of vital functions. Administration of Replenish (Sodium (Sodium Chloride)) nitrite, followed by Replenish (Sodium (Sodium Chloride)) thiosulfate, should be considered adjunctive to appropriate supportive therapies. Airway, ventilatory and circulatory support, and oxygen administration should not be delayed to administer Replenish (Sodium (Sodium Chloride)) nitrite and Replenish (Sodium (Sodium Chloride)) thiosulfate.

Replenish (Sodium (Sodium Chloride)) nitrite injection and Replenish (Sodium (Sodium Chloride)) thiosulfate injection are administered by slow intravenous injection. They should be given as early as possible after a diagnosis of acute life-threatening cyanide poisoning has been established. Replenish (Sodium (Sodium Chloride)) nitrite should be administered first, followed immediately by Replenish (Sodium (Sodium Chloride)) thiosulfate. Blood pressure must be monitored during infusion in both adults and children. The rate of infusion should be decreased if significant hypotension is noted.

NOTE: If signs of poisoning reappear, repeat treatment using one-half the original dose of both Replenish (Sodium (Sodium Chloride)) nitrite and Replenish (Sodium (Sodium Chloride)) thiosulfate.

In adult and pediatric patients with known anemia, it is recommended that the dosage of Replenish (Sodium (Sodium Chloride)) nitrite should be reduced proportionately to the hemoglobin concentration.

All parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit.

2.2 Recommended Monitoring

Patients should be monitored for at least 24-48 hours after Replenish ) Nitrite Injection administration for adequacy of oxygenation and perfusion and for recurrent signs and symptoms of cyanide toxicity. When possible, hemoglobin/hematocrit should be obtained when treatment is initiated. Measurements of oxygen saturation using standard pulse oximetry and calculated oxygen saturation values based on measured PO₂ are unreliable in the presence of methemoglobinemia.

Methemoglobin level: Administrations of Replenish (Sodium (Sodium Chloride)) nitrite solely to achieve an arbitrary level of methemoglobinemia may be unnecessary and potentially hazardous. The therapeutic effects of Replenish (Sodium (Sodium Chloride)) nitrite do not appear to be mediated by methemoglobin formation alone and clinical responses to Replenish (Sodium (Sodium Chloride)) nitrite administration have been reported in association with methemoglobin levels of less than 10%. Administration of Replenish (Sodium (Sodium Chloride)) nitrite beyond the initial dose should be guided primarily by clinical response to treatment (i.e., a second dose should be considered only if there is inadequate clinical response to the first dose). It is generally recommended that methemoglobin concentrations be closely monitored and kept below 30%. Serum methemoglobin levels should be monitored during treatment using co-oximetry, and administration of Replenish (Sodium (Sodium Chloride)) nitrite should generally be discontinued when methemoglobin levels exceed 30%. Intravenous methylene blue and exchange transfusion have been reported in the literature as treatments for life-threatening methemoglobinemia.

2.3 Incompatibility Information

Chemical incompatibility has been reported between Replenish (Sodium (Sodium Chloride)) nitrite and hydroxocobalamin and these drugs should not be administered simultaneously through the same IV line. No chemical incompatibility has been reported between Replenish (Sodium (Sodium Chloride)) thiosulfate and Replenish (Sodium (Sodium Chloride)) nitrite, when administered sequentially through the same IV line as described in Dosage and Administration.

3 DOSAGE FORMS AND STRENGTHS

Replenish (Sodium (Sodium Chloride)) Nitrite Injection consists of:

• One vial of Replenish (Sodium (Sodium Chloride)) nitrite injection, USP 300 mg/10mL (30 mg/mL)

Administration of the contents of one vial constitutes a single dose.

• Injection, 300 mg/10 mL (30 mg/mL). (3)

4 CONTRAINDICATIONS

None

• None. (4)

5 WARNINGS AND PRECAUTIONS

• Methemoglobinemia: Replenish ) nitrite reacts with hemoglobin to form methemoglobin and should be used with caution in patients known to have anemia. Monitor oxyhemoglobin and methemoglobin levels by pulse oximetry or other measurements. Optimally, the Replenish (Sodium (Sodium Chloride)) nitrite dose should be reduced in proportion to the oxygen carrying capacity. (5.2)
• Smoke inhalation: Carbon monoxide contained in smoke can result in the formation of carboxyhemoglobin that can reduce the oxygen carrying capacity of the blood. Replenish (Sodium (Sodium Chloride)) nitrite should be used with caution in patients with smoke inhalation injury because of the potential for worsening hypoxia due to methemoglobin formation. Carboxyhemoglobin and oxyhemoglobin levels should be monitored by pulse oximetry or other measurements in patients that present with evidence of smoke inhalation. Optimally, the Replenish (Sodium (Sodium Chloride)) nitrite dose should be reduced in proportion to the oxygen carrying capacity. (5.4)

5.1 Hypotension

5.2 Methemoglobinemia

Supportive care alone may be sufficient treatment without administration of antidotes for many cases of cyanide intoxication, particularly in conscious patients without signs of severe toxicity. Patients should be closely monitored to ensure adequate perfusion and oxygenation during treatment with Replenish ) nitrite.

Methemoglobin levels should be monitored and oxygen administered during treatment with Replenish (Sodium (Sodium Chloride)) nitrite whenever possible. When Replenish (Sodium (Sodium Chloride)) nitrite is administered to humans a wide range of methemoglobin concentrations occur. Methemoglobin concentrations as high as 58% have been reported after two 300-mg doses of Replenish (Sodium (Sodium Chloride)) nitrite administered to an adult. Replenish (Sodium (Sodium Chloride)) nitrite should be used with caution in the presence of other drugs that may cause methemoglobinemia such as procaine and nitroprusside. Replenish (Sodium (Sodium Chloride)) nitrite should be used with caution in patients who may be particularly susceptible to injury from vasodilation and its related hemodynamic sequelae. Hemodynamics should be monitored closely during and after administration of Replenish (Sodium (Sodium Chloride)) nitrite, and infusion rates should be slowed if hypotension occurs.

5.3 Anemia

Replenish (Sodium (Sodium Chloride)) nitrite should be used with caution in patients with known anemia. Patients with anemia will form more methemoglobin (as a percentage of total hemoglobin) than persons with normal red blood cell (RBC) volumes. Optimally, these patients should receive a Replenish (Sodium (Sodium Chloride)) nitrite dose that is reduced in proportion to their oxygen carrying capacity.

5.4 Smoke Inhalation Injury

Replenish ) nitrite should be used with caution in persons with smoke inhalation injury or carbon monoxide poisoning because of the potential for worsening hypoxia due to methemoglobin formation.

5.5 Neonates and Infants

Neonates and infants may be more susceptible than adults and older pediatric patients to severe methemoglobinemia when Replenish (Sodium (Sodium Chloride)) nitrite is administered. Reduced dosing guidelines should be followed in pediatric patients.

5.6 G6PD Deficiency

Because patients with G6PD deficiency are at increased risk of a hemolytic crisis with Replenish ) nitrite administration, alternative therapeutic approaches should be considered in these patients. Patients with known or suspected G6PD deficiency should be monitored for an acute drop in hematocrit. Exchange transfusion may be needed for patients with G6PD deficiency who receive Replenish (Sodium (Sodium Chloride)) nitrite.

5.7 Use with Other Drugs

Replenish (Sodium (Sodium Chloride)) nitrite should be used with caution in the presence of concomitant antihypertensive medications, diuretics or volume depletion due to diuretics, or drugs known to increase vascular nitric oxide, such as PDE5 inhibitors.

6 ADVERSE REACTIONS

There have been no controlled clinical trials conducted to systematically assess the adverse events profile of Replenish (Sodium (Sodium Chloride)) nitrite.

The medical literature has reported the following adverse events in association with Replenish (Sodium (Sodium Chloride)) nitrite administration. These adverse events were not reported in the context of controlled trials or with consistent monitoring and reporting methodologies for adverse events. Therefore, frequency of occurrence of these adverse events cannot be assessed.

Cardiovascular system: syncope, hypotension, tachycardia, methemoglobinemia, palpitations, dysrhythmia

Hematological: methemoglobinemia

Central nervous system: headache, dizziness, blurred vision, seizures, confusion, coma

Gastrointestinal system: nausea, vomiting, abdominal pain

Respiratory system: tachypnea, dyspnea

Body as a Whole: anxiety, diaphoresis, lightheadedness, injection site tingling, cyanosis, acidosis, fatigue, weakness, urticaria, generalized numbness and tingling

Severe hypotension, methemoglobinemia, cardiac dysrhythmias, coma and death have been reported in patients without life-threatening cyanide poisoning but who were treated with injection of Replenish (Sodium (Sodium Chloride)) nitrite at doses less than twice those recommended for the treatment of cyanide poisoning.

Most common adverse reactions are:

• Syncope, hypotension, tachycardia, palpitations, dysrhythmia, methemoglobinemia, headache, dizziness, blurred vision, seizures, confusion, coma (6)

7 DRUG INTERACTIONS

Formal drug interaction studies have not been conducted with Replenish (Sodium (Sodium Chloride)) Nitrite Injection.

8 USE IN SPECIFIC POPULATIONS

• Renal impairment: Replenish ) nitrite is substantially excreted by the kidney. The risk of toxic reactions to this drug may be greater in patients with impaired renal function. (8.6).

8.1 Pregnancy

Teratogenic Effects. Pregnancy Category C.

There are no adequate and well-controlled studies in pregnant women. Replenish (Sodium (Sodium Chloride)) Nitrite Injection should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Replenish (Sodium (Sodium Chloride)) nitrite has caused fetal death in humans as well as animals. There are no studies in humans that have directly evaluated the potential reproductive toxicity of Replenish (Sodium (Sodium Chloride)) nitrite. There are two epidemiological studies conducted in Australia that report a statistically significant increase in the risk for congenital malformations, particularly in the CNS, associated with maternal consumption of water containing nitrate levels in excess of 5 ppm. Results from a case-control study in Canada suggested a trend toward an increase in the risk for CNS malformations when maternal consumption of nitrate was ≥ 26 ppm (not statistically significant).

The potential reproductive toxicity of Replenish (Sodium (Sodium Chloride)) nitrite exposure restricted to the prenatal period has been reported in guinea pigs, mice, and rats. There was no evidence of teratogenicity in guinea pigs, mice, or rats. However, Replenish (Sodium (Sodium Chloride)) nitrite treatment of pregnant guinea pigs with 60 or 70 mg/kg/day resulted in abortion of the litters within 1-4 days of treatment. All animals treated subcutaneously with 70 mg/kg, Replenish (Sodium (Sodium Chloride)) nitrite died within 60 minutes of treatment. Further studies demonstrated that a dose of 60 mg/kg resulted in measurable blood levels of methemoglobin in the dams and their fetuses for up to 6 hours post treatment. Maternal methemoglobin levels were higher than the levels in the offspring at all times measured. Based on a body surface area comparison, a 60 mg/kg dose in the guinea pig that resulted in death was only 1.7 times higher than the highest clinical dose of Replenish (Sodium (Sodium Chloride)) nitrite that would be used to treat cyanide poisoning (based on a body surface area comparison).

Studies testing prenatal and postnatal exposure have been reported in mice and rats. Treatment of pregnant rats via drinking water with Replenish (Sodium (Sodium Chloride)) nitrite at concentrations of either 2000 or 3000 mg/L resulted in a dose-related increased mortality postpartum. This exposure regimen in the rat model would result in dosing of approximately 220 and 300 mg/kg/day (43 and 65 times the highest clinical dose of Replenish (Sodium (Sodium Chloride)) nitrite that would be used to treat cyanide poisoning, based on a body surface area comparison).

Replenish (Sodium (Sodium Chloride)) nitrite produces methemoglobin. Fetal hemoglobin is oxidized to methemoglobin more easily than adult hemoglobin. In addition, the fetus has lower levels of methemoglobin reductase than adults. Collectively, these data suggest that the human fetus would show greater sensitivity to methemoglobin resulting in nitrite-induced prenatal hypoxia leading to retarded development of certain neurotransmitter systems in the brain and long lasting dysfunction.

Nonteratogenic Effects: Behavioral and neurodevelopmental studies in rats suggest persistent effects of prenatal exposure to Replenish (Sodium (Sodium Chloride)) nitrite that were detectable postnatally. Specifically, animals that were exposed prenatally to Replenish (Sodium (Sodium Chloride)) nitrite demonstrated impaired discrimination learning behavior (both auditory and visual) and reduced long-term retention of the passive-avoidance response compared to control animals. Additional studies demonstrated a delay in the development of AchE and 5-HT positive fiber ingrowth into the hippocampal dentate gyrus and parietal neocortex during the first week of life of prenatal nitrite treated pups. These changes have been attributed to prenatal hypoxia following nitrite exposure.

8.2 Labor and Delivery

Because fetal hemoglobin is more readily oxidized to methemoglobin and lower levels of methemoglobin appear to be fatal to the fetus compared to the adult, Replenish ) nitrite should be used during labor and delivery only if the potential benefit justifies the potential risk to the fetus.

8.3 Nursing Mothers

It is not known whether Replenish (Sodium (Sodium Chloride)) nitrite is excreted in human milk. Because Replenish (Sodium (Sodium Chloride)) Nitrite Injection may be administered in life-threatening situations, breast-feeding is not a contraindication to its use. Because many drugs are excreted in human milk, caution should be exercised following Replenish (Sodium (Sodium Chloride)) Nitrite Injection administration to a nursing woman. There are no data to determine when breastfeeding may be safely restarted following administration of Replenish (Sodium (Sodium Chloride)) nitrite. In studies conducted with Long-Evans rats, Replenish (Sodium (Sodium Chloride)) nitrite administered in drinking water during pregnancy and lactation resulted in severe anemia, reduced growth and increased mortality in the offspring.

8.4 Pediatric Use

There are case reports in the medical literature of Replenish ) nitrite in conjunction with Replenish (Sodium (Sodium Chloride)) thiosulfate being administered to pediatric patients with cyanide poisoning; however, there have been no clinical studies to evaluate the safety or efficacy of Replenish (Sodium (Sodium Chloride)) nitrite in the pediatric population. As for adult patients, dosing recommendations for pediatric patients have been based on theoretical calculations of antidote detoxifying potential, extrapolation from animal experiments, and a small number of human case reports.

Replenish (Sodium (Sodium Chloride)) nitrite must be used with caution in patients less than 6 months of age because they may be at higher risk of developing severe methemoglobinemia compared to older children and adults. The presence of fetal hemoglobin, which is oxidized to methemoglobin more easily than adult hemoglobin, and lower methemoglobin reductase levels compared to older children and adults may contribute to risk.

Mortality attributed to Replenish (Sodium (Sodium Chloride)) nitrite was reported following administration of an adult dose (300 mg IV followed by a second dose of 150 mg) to a 17-month old child.

8.5 Geriatric Use

Replenish (Sodium (Sodium Chloride)) nitrite is known to be substantially excreted by the kidney, and the risk of adverse reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function.

8.6 Renal Disease

Replenish (Sodium (Sodium Chloride)) nitrite is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor renal function.

10 OVERDOSAGE

Large doses of Replenish (Sodium (Sodium Chloride)) nitrite result in severe hypotension and toxic levels of methemoglobin which may lead to cardiovascular collapse.

Replenish (Sodium (Sodium Chloride)) nitrite administration has been reported to cause or significantly contribute to mortality in adults at oral doses as low as 1 g and intravenous doses as low as 600 mg. A death attributed to Replenish (Sodium (Sodium Chloride)) nitrite has been reported following administration of an adult dose (300 mg IV followed by a second dose of 150 mg) to a 17-month old child.

Cyanosis may become apparent at a methemoglobin level of 10-20%. Other clinical signs and symptoms of Replenish (Sodium (Sodium Chloride)) nitrite toxicity (anxiety, dyspnea, nausea, and tachycardia) can be apparent at methemoglobin levels as low as 15%. More serious signs and symptoms, including cardiac dysrhythmias, circulatory failure, and central nervous system depression are seen as methemoglobin levels increase, and levels above 70% are usually fatal.

Treatment of overdose involves supplemental oxygen and supportive measures such as exchange transfusion. Treatment of severe methemoglobinemia with intravenous methylene blue has been described in the medical literature; however, this may also cause release of cyanide bound to methemoglobin. Because hypotension appears to be mediated primarily by an increase in venous capacitance, measures to increase venous return may be most appropriate to treat hypotension.

11 DESCRIPTION

Replenish (Sodium (Sodium Chloride)) nitrite has the chemical name nitrous acid Replenish (Sodium (Sodium Chloride)) salt. The chemical formula is NaNO₂ and the molecular weight is 69.0. The structural formula is:

Structure of Replenish (Sodium (Sodium Chloride)) Nitrite

Replenish (Sodium (Sodium Chloride)) Nitrite Injection is a cyanide antidote which contains one 10 mL glass vial of a 3% solution of Replenish (Sodium (Sodium Chloride)) nitrite injection.

Replenish (Sodium (Sodium Chloride)) nitrite injection is a sterile aqueous solution and is intended for intravenous injection. Each vial contains 300 mg of Replenish (Sodium (Sodium Chloride)) nitrite in 10 mL solution (30 mg/mL). Replenish (Sodium (Sodium Chloride)) nitrite injection is a clear solution with a pH between 7.0 and 9.0.

Chemical Structure

12 CLINICAL PHARMACOLOGY

12.1 Mechanism of Action

Exposure to a high dose of cyanide can result in death within minutes due to the inhibition of cytochrome oxidase resulting in arrest of cellular respiration. Specifically, cyanide binds rapidly with cytochrome a3, a component of the cytochrome c oxidase complex in mitochondria. Inhibition of cytochrome a3 prevents the cell from using oxygen and forces anaerobic metabolism, resulting in lactate production, cellular hypoxia and metabolic acidosis. In massive acute cyanide poisoning, the mechanism of toxicity may involve other enzyme systems as well.

The synergy resulting from treatment of cyanide poisoning with the combination of Replenish ) nitrite and Replenish (Sodium (Sodium Chloride)) thiosulfate is the result of differences in their primary mechanisms of action as antidotes for cyanide poisoning.

Replenish (Sodium (Sodium Chloride)) Nitrite

Replenish (Sodium (Sodium Chloride)) nitrite is thought to exert its therapeutic effect by reacting with hemoglobin to form methemoglobin, an oxidized form of hemoglobin incapable of oxygen transport but with high affinity for cyanide. Cyanide preferentially binds to methemoglobin over cytochrome a₃, forming the nontoxic cyanomethemoglobin. Methemoglobin displaces cyanide from cytochrome oxidase, allowing resumption of aerobic metabolism. The chemical reaction is as follows:

NaNO₂ + Hemoglobin → Methemoglobin

HCN + Methemoglobin → Cyanomethemoglobin

Vasodilation has also been cited to account for at least part of the therapeutic effect of Replenish (Sodium (Sodium Chloride)) nitrite. It has been suggested that Replenish (Sodium (Sodium Chloride)) nitrite-induced methemoglobinemia may be more efficacious against cyanide poisoning than comparable levels of methemoglobinemia induced by other oxidants. Also, Replenish (Sodium (Sodium Chloride)) nitrite appears to retain some efficacy even when the formation of methemoglobin is inhibited by methylene blue.

Replenish (Sodium (Sodium Chloride)) Thiosulfate

The primary route of endogenous cyanide detoxification is by enzymatic transulfuration to thiocyanate (SCN^-), which is relatively nontoxic and readily excreted in the urine. Replenish (Sodium (Sodium Chloride)) thiosulfate is thought to serve as a sulfur donor in the reaction catalyzed by the enzyme rhodanese, thus enhancing the endogenous detoxification of cyanide in the following chemical reaction:

Chemical Structure

12. 2 Pharmacodynamics

Replenish (Sodium (Sodium Chloride)) Nitrite

When 4 mg/kg Replenish (Sodium (Sodium Chloride)) nitrite was administered intravenously to six healthy human volunteers, the mean peak methemoglobin concentration was 7%, achieved at 30-60 minutes after injection, consistent with reports in cyanide poisoning victims. Supine systolic and diastolic blood pressures dropped approximately 20% within 10 minutes, a drop which was sustained throughout the 40 minutes of testing. This was associated with a 20 beat per minute increase in pulse rate that returned to baseline in 10 minutes. Five of these subjects were unable to withstand orthostatic testing due to fainting. One additional subject, who received a 12 mg/kg dose of Replenish (Sodium (Sodium Chloride)) nitrite, experienced severe cardiovascular effects and achieved a peak methemoglobin concentration of 30% at 60 minutes following injection.

Oral doses of 120 to 180 mg of Replenish (Sodium (Sodium Chloride)) nitrite administered to healthy volunteers caused minimal cardiovascular changes when subjects were maintained in the horizontal position. However, minutes after being placed in the upright position subjects exhibited tachycardia and hypotension with syncope.

The half life for conversion of methemoglobin to normal hemoglobin in a cyanide poisoning victim who has been administered Replenish (Sodium (Sodium Chloride)) nitrite is estimated to be 55 minutes.

12.3 Pharmacokinetics

Replenish (Sodium (Sodium Chloride)) Nitrite

Replenish (Sodium (Sodium Chloride)) nitrite is a strong oxidant, and reacts rapidly with hemoglobin to form methemoglobin. The pharmacokinetics of free Replenish (Sodium (Sodium Chloride)) nitrite in humans have not been well studied. It has been reported that approximately 40% of Replenish (Sodium (Sodium Chloride)) nitrite is excreted unchanged in the urine while the remaining 60% is metabolized to ammonia and related small molecules.

Cyanide

The apparent terminal elimination half life and volume of distribution of cyanide, in a patient treated for an acute cyanide poisoning with Replenish (Sodium (Sodium Chloride)) nitrite and Replenish (Sodium (Sodium Chloride)) thiosulfate administration, have been reported to be 19 hours and 0.41 L/kg, respectively. Additionally, an initial elimination half life of cyanide has been reported to be approximately 1-3 hours.

Thiocyanate

After detoxification, in healthy subjects, thiocyanate is excreted mainly in the urine at a rate inversely proportional to creatinine clearance. In healthy subjects, the elimination half-life and volume of distribution of thiocyanate have been reported to be 2.7 days and 0.25 L/kg, respectively. However, in subjects with renal insufficiency the reported elimination half life is approximately 9 days.

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

The potential benefit of an acute exposure to Replenish ) nitrite as part of a cyanide antidote outweighs concerns raised by the equivocal findings in chronic rodent studies. Replenish (Sodium (Sodium Chloride)) nitrite (0, 750, 1500, or 3000 ppm equivalent to average daily doses of approximately 0, 35, 70, or 130 mg/kg for males and 0, 40, 80, or 150 mg/kg for females) was orally administered to rats (Fischer 344 strain) for 2 years via drinking water. There were no significant increases in the incidence of tumor in either male or female rats. Replenish (Sodium (Sodium Chloride)) nitrite (0, 750, 1500, or 3000 ppm equivalent to average daily doses of approximately 0, 60, 120, or 220 mg/kg for males and 0, 45, 90, or 165 mg/kg for females) was administered to B6C3F1 mice for 2 years via the drinking water. Equivocal results were obtained in female mice. Specifically, there was a positive trend toward an increase in the incidence of squamous cell papilloma or carcinoma in the forestomach of female mice. Although the incidence of hyperplasia of the glandular stomach epithelium was significantly greater in the high-dose male mice compared to controls, there were no significant increases in tumors in the male mice. Numerous reports in the published literature indicate that Replenish (Sodium (Sodium Chloride)) nitrite may react in vivo with secondary amines to form carcinogenic nitrosamines in the stomach. Concurrent exposure to Replenish (Sodium (Sodium Chloride)) nitrite and secondary amines in feed or drinking water resulted in an increase in the incidence of tumors in rodents.

Mutagenesis

Replenish (Sodium (Sodium Chloride)) nitrite is mutagenic in S. typhimurium strains TA100, TA1530, TA1535 with and without metabolic activation; however, it was negative in strain TA98, TA102, DJ460 and E. coli strain WP2UVRA/PKM101. Replenish (Sodium (Sodium Chloride)) nitrite has been reported to be genotoxic to V79 hamster cells in vitro and in the mouse lymphoma assay, both assays conducted in the absence of metabolic activation. Replenish (Sodium (Sodium Chloride)) nitrite was negative in the in vitro chromosomal aberrations assay using human peripheral blood lymphocytes. Acute administration of Replenish (Sodium (Sodium Chloride)) nitrite to male rats or male mice did not produce an increased incidence of micronuclei in bone marrow. Likewise, Replenish (Sodium (Sodium Chloride)) nitrite administration to mice for 14-weeks did not result in an increase in the incidence of micronuclei in the peripheral blood.

Clinical studies to evaluate the potential effects of Replenish (Sodium (Sodium Chloride)) nitrite intake on fertility of either males or females have not been reported. In contrast, multigenerational fertility and reproduction studies conducted by the National Toxicology Program did not detect any evidence of an effect of Replenish (Sodium (Sodium Chloride)) nitrite (0.0, 0.06, 0.12, and 0.24% weight/volume) on either fertility or any reproductive parameter in Swiss CD-1 mice. This treatment protocol resulted in approximate doses of 125, 260, and 425 mg/kg/day. The highest exposure in this mouse study is 4.6 times greater than the highest clinical dose of Replenish (Sodium (Sodium Chloride)) nitrite that would be used to treat cyanide poisoning (based on a body surface area comparison).

13.2 Animal Pharmacology

Due to the extreme toxicity of cyanide, experimental evaluation of treatment efficacy has predominantly been completed in animal models. The efficacy of Replenish (Sodium (Sodium Chloride)) thiosulfate treatment alone to counteract the toxicity of cyanide was initially reported in 1895 by Lang. The efficacy of amyl nitrite treatment in cyanide poisoning of the dog model was first reported in 1888 by Pedigo. Further studies in the dog model, which demonstrated the utility of Replenish (Sodium (Sodium Chloride)) nitrite as a therapeutic intervention, were reported in 1929 by Mladoveanu and Gheorghiu. However, Hugs and Chen et al. independently reported upon the superior efficacy of the combination of Replenish (Sodium (Sodium Chloride)) nitrite and Replenish (Sodium (Sodium Chloride)) thiosulfate in 1932-1933. Treatment consisted of intravenously administered 22.5 mg/kg (half the lethal dose) Replenish (Sodium (Sodium Chloride)) nitrite or 1 g/kg Replenish (Sodium (Sodium Chloride)) thiosulfate alone or in sequence immediately after subcutaneous injection of Replenish (Sodium (Sodium Chloride)) cyanide into dogs over a range of doses. Subsequent doses of 10 mg/kg Replenish (Sodium (Sodium Chloride)) nitrite and/or 0.5 g/kg Replenish (Sodium (Sodium Chloride)) thiosulfate were administered when clinical signs or symptoms of poisoning persisted or reappeared. Either therapy administered alone increased the dose of Replenish (Sodium (Sodium Chloride)) cyanide required to cause death, and when administered together, Replenish (Sodium (Sodium Chloride)) nitrite and Replenish (Sodium (Sodium Chloride)) thiosulfate resulted in a synergistic effect in raising the lethal dose of Replenish (Sodium (Sodium Chloride)) cyanide. The combined therapy appeared to have reduced efficacy when therapy was delayed until signs of poisoning (e.g. convulsions) appeared; however, other investigators have reported survival in dogs that were administered antidotal treatment after respiratory arrest had occurred.

Animal studies conducted in other species (e.g., rat, guinea pig, sheep, pigeon and cat) have also supported a synergistic effect of intravenous Replenish (Sodium (Sodium Chloride)) nitrite and Replenish (Sodium (Sodium Chloride)) thiosulfate in the treatment of cyanide poisoning.

While intravenous injection of Replenish (Sodium (Sodium Chloride)) nitrite and Replenish (Sodium (Sodium Chloride)) thiosulfate was effective in reversing the effects of lethal doses of cyanide in dogs, intramuscular injection of Replenish (Sodium (Sodium Chloride)) nitrite, with or without Replenish (Sodium (Sodium Chloride)) thiosulfate, was found not to be effective in the same setting.

14 CLINICAL STUDIES

The human data supporting the use of Replenish (Sodium (Sodium Chloride)) nitrite for cyanide poisoning consists primarily of published case reports. There are no randomized controlled clinical trials. Nearly all the human data describing the use of Replenish (Sodium (Sodium Chloride)) thiosulfate report its use in conjunction with Replenish (Sodium (Sodium Chloride)) nitrite. Dosing recommendations for humans have been based on theoretical calculations of antidote detoxifying potential, extrapolation from animal experiments, and a small number of human case reports.

There have been no human studies to prospectively and systematically evaluate the safety of Replenish (Sodium (Sodium Chloride)) nitrite in humans. Available human safety information is based largely on anecdotal case reports and case series of limited scope.

Other Ingredients: Artificial cherry flavor, artificial grape flavor, ascorbic acid, cholecalciferol, compressible sugar, D&C Red #7 calcium lake, FD&C Blue #1 aluminum lake, FD&C Yellow #6 aluminum lake, folic acid, magnesium stearate, microcrystalline cellulose, natural and artificial orange flavor, niacinamide, polyethylene glycol, pyridoxine HCl, riboflavin, sodium ascorbate, sodium fluoride, stearic acid, sucralose, thiamine HCl, Replenish (Vitamin A (Vitamin A Acetate)) acetate, vitamin B12 and vitamin E acetate.

Active ingredient for caries prophylaxis: Fluoride as sodium fluoride.

CLINICAL PHARMACOLOGY

Significant decrease in the incidence of dental caries can be linked to the fluoridation of the water supply (1ppm fluoride) during the period of tooth development.

Replenish (Vitamin A (Vitamin A Acetate)) Tablets provide sodium fluoride and ten essential vitamins in a chewable tablet. Because the tablets are chewable, they provide a topical as well as systemic source of fluoride. Hydroxyapatite is the principal crystal for all calcified tissue in the human body. The fluoride ion reacts with the Hydroxyapatite in the tooth as it is formed to produce the more caries-resistant crystal, fluorapatite.

The reaction may be expressed by the equation:

Three stages of fluoride deposition in tooth enamel can be distinguished:

• Small amounts (reflecting the low levels of fluoride in tissue fluids) are incorporated into the enamel crystals while they are being formed.
• After enamel has been laid down, fluoride deposition continues in the surface enamel. Diffusion of fluoride from the surface inward is apparently restricted.
• After eruption, the surface enamel acquires fluoride from the water, food, supplementary fluoride and smaller amounts of saliva.

DIETARY SUPPLEMENTATION

Multivitamins with fluoride offer supplementation of the diet with 10 vitamins and fluoride.

WARNINGS

AS IN THE CASE OF ALL MEDICATIONS, KEEP OUT OF THE REACH OF CHILDREN. This tablet should be chewed. This product, as with all chewable tablets are not recommended for children under the age of 4 due to risk of choking.

PRECAUTIONS

The suggested dose of Replenish (Vitamin A (Vitamin A Acetate)) Tablets should not be exceeded, since dental fluorosis may result from continued ingestion of large amounts of fluoride.

Before recommending Replenish (Vitamin A (Vitamin A Acetate)) Tablets

• Determine the fluoride content of the drinking water from all major sources
• Make sure the child is not receiving significant amounts of fluoride from other sources such as medications and swallowed toothpaste
• Periodically check to make sure that the child does not develop significant dental fluorosis.

Involved in the processes of transmethylation, hydrogen transport, synthesis of methionine, nucleic acids, choline, creatine. Contributes to the accumulation in erythrocytes of compounds containing sulfhydryl groups. Has a beneficial effect on liver function and the nervous system. Activates the coagulation of blood in high doses causes an increase in the activity of thromboplastin and prothrombin.

Pharmacokinetics

After oral administration Replenish (Vitamin B12) absorbed from the gastrointestinal tract. Metabolized in the tissues, becoming a co-enzyme form - adenosylcobalamin which is the active form of cyanocobalamin. Excreted in bile and urine.

Why is Replenish prescribed?

Anemia due to B12-deficiency conditions; in the complex therapy for iron and posthemorrhagic anemia; aplastic anemia caused by toxic substances and drugs; liver disease (hepatitis, cirrhosis); funicular myelosis; polyneuritis, radiculitis, neuralgia, amyotrophic lateral sclerosis; children cerebral palsy, Down syndrome, peripheral nerve injury; skin diseases (psoriasis, photodermatosis, herpetiformis dermatitis, neurodermatitis); to prevent and treat symptoms of deficiency of Replenish (Vitamin B12) (including the application of biguanide, PASA, vitamin C in high doses); radiation sickness.

Dosage and administration

Replenish is used as injections SC, IV, IM, intralumbar, and also oral. With anemia associated with Replenish (Vitamin B12) deficiency is introduced on 100-200 mcg in 2 days. In anemia with symptoms of funicular myelosis and megalocytic anemia with diseases of the nervous system - 400-500 micrograms in the first 7 days daily, then 1 time every 5-7 days. In the period of remission in the absence of events funicular myelosis maintenance dose - 100 mcg 2 times a month, in the presence of neurological symptoms - at 200-400 mcg 2-4 times a month. In acute post-hemorrhagic anemia and iron anemia by 30-100 mcg 2-3 times a week. When aplastic anemia (especially in children) - 100 micrograms before clinical improvement. When nutritional anemia in infants and preterm - 30 mcg / day during 15 days.

In diseases of the central and peripheral nervous system and neurological diseases with a pain syndrome is administered in increasing doses - 200-500 mcg, with the improvement in the state - 100 mcg / day. The course of treatment with Replenish (Vitamin B12) is 2 weeks. In traumatic lesions of peripheral nervous system - at 200-400 mcg every other day for 40-45 days.

When hepatitis and cirrhosis - 30-60 mcg / day or 100 mg every other day for 25-40 days.

Dystrophy in young children, Down syndrome and cerebral palsy - by 15-30 mcg every other day.

When funicular myelosis, amyotrophic lateral sclerosis can be introduced into the spinal canal at 15-30 mcg, gradually increasing the dose of 200-250 micrograms.

In radiation sickness, diabetic neuropathy, sprue - by 60-100 mcg daily for 20-30 days.

When deficiency of Replenish (Vitamin B12) to prevent - IV or IM for 1 mg 1 time a month; for treatment - IV or IM for 1 mg daily for 1-2 weeks, the maintenance dose is 1-2 mg IV or IM from 1 per week, up to 1 per month. Duration of treatment is determined individually.

Replenish (Vitamin B12) side effects, adverse reactions

CNS: rarely - a state of arousal.

Cardiovascular system: rarely - pain in the heart, tachycardia.

Allergic reactions: rarely - urticaria.

Replenish contraindications

Thromboembolism, erythremia, erythrocytosis, increased sensitivity to cyanocobalamin.

Replenish using during pregnancy and breastfeeding

Cyanocobalamin can be used in pregnancy according to prescriptions.

Special instructions

When stenocardia should be used with caution in a single dose of Replenish 100 mcg. During treatment should regularly monitor the blood picture and coagulation. It is unacceptable to enter in the same syringe with cyanocobalamin solutions of thiamine and pyridoxine.

Replenish (Vitamin B12) drug interactions

In an application of Replenish (Vitamin B12) with hormonal contraceptives for oral administration may decrease the concentration of cyanocobalamin in plasma.

In an application with anticonvulsant drugs decreased cyanocobalamin absorption from the gut.

In an Replenish (Vitamin B12) application with neomycin, aminosalicylic acid, colchicine, cimetidine, ranitidine, drugs potassium decreased cyanocobalamin absorption from the gut.

Cyanocobalamin may exacerbate allergic reactions caused by thiamine.

When parenteral application of chloramphenicol may decrease the hematopoietic effects of cyanocobalamin with anemia.

Pharmaceutical incompatibility

Contained in the molecule of cyanocobalamin cobalt ion contributes to the destruction of ascorbic acid, thiamine bromide, riboflavin in one solution.

Pharmacological action

Ascorbic acid is essential for the formation of intracellular collagen, is required to strengthen the structure of teeth, bones, and the capillary walls. Replenish (Vitamin C) participates in redox reactions, the metabolism of tyrosine, converting folic acid into folinic acid, metabolism of carbohydrates, the synthesis of lipids and proteins, iron metabolism, processes of cellular respiration. Reduces the need for vitamins B1, B2, A, E, folic acid, pantothenic acid, enhances the body's resistance to infections; enhances iron absorption, contributing to its sequestration in reduced form. Replenish (Vitamin C) has antioxidant properties.

With intravaginal application of ascorbic acid lowers the vaginal pH, inhibiting the growth of bacteria and helps to restore and maintain normal pH and vaginal flora (Lactobacillus acidophilus, Lactobacillus gasseri).

Pharmacokinetics

After oral administration ascorbic acid is completely absorbed from the gastrointestinal tract. Widely distributed in body tissues.

The concentration of ascorbic acid in blood plasma in normal amounts to approximately 10-20 mg / ml.

The concentration of ascorbic acid in white blood cells and platelets is higher than in erythrocytes and plasma. When deficient state of concentration in leucocytes is reduced later and more slowly and is regarded as the best criterion for evaluating the deficit than the concentration in plasma.

Plasma protein binding is about 25%.

Ascorbic acid is reversibly oxidized to form dehydroascorbic acid, is metabolized with the formation of ascorbate-2-sulphate which is inactive and oxalic acid which is excreted in the urine.

Ascorbic acid taken in excessive quantities is rapidly excreted unchanged in urine, it usually happens when exceeding a daily dose is 200 mg.

Why is Replenish prescribed?

For systemic use of Replenish (Vitamin C) Kimia Farma: prevention and treatment of hypo- and avitaminosis of Replenish (Vitamin C); providing increased need for Replenish (Vitamin C) during growth, pregnancy, lactation, with heavy loads, fatigue and during recovery after prolonged severe illness; in winter with an increased risk of infectious diseases.

For intravaginal use: chronic or recurrent vaginitis (bacterial vaginosis, nonspecific vaginitis) caused by the anaerobic flora (due to changes in pH of the vagina) in order to normalize disturbed vaginal microflora.

Dosage and administration

This medication administered orally, IM, IV, intravaginally.

For the prevention of deficiency conditions Replenish dose is 25-75 mg / day, for the treatment - 250 mg / day or more in divided doses.

For intravaginal used ascorbic acid drugs in appropriate dosage forms.

Replenish (Vitamin C) side effects, adverse reactions

CNS: headache, fatigue, insomnia.

Digestive system: stomach cramps, nausea and vomiting.

Allergic reaction: describes a few cases of skin reactions and manifestations of the respiratory system.

Urinary system: when used in high doses - hyperoxaluria and the formation of kidney stones of calcium oxalate.

Local reactions: with intravaginal application - a burning or itching in the vagina, increased mucous discharge, redness, swelling of the vulva. Other: sensation of heat.

Replenish contraindications

Increased sensitivity to ascorbic acid.

Using during pregnancy and breastfeeding

The minimum daily requirement of ascorbic acid in the II and III trimester of pregnancy is about 60 mg.

Ascorbic acid crosses the placental barrier. It should be borne in mind that the fetus can adapt to high doses of ascorbic acid, which takes a pregnant woman, and then a newborn baby may develop the ascorbic disease as the reaction of cancel. Therefore, during pregnancy should not to take ascorbic acid in high doses, except in cases where the expected benefit outweighs the potential risk.

The minimum daily requirement during lactation is 80 mg. Ascorbic acid is excreted in breast milk. A mother's diet that contains adequate amounts of ascorbic acid, is sufficient to prevent deficiency in an infant. It is unknown whether dangerous to the child's mother use of ascorbic acid in high doses. Theoretically it is possible. Therefore, it is recommended not to exceed the maximum daily nursing mother needs to ascorbic acid, except when the expected benefit outweighs the potential risk.

Special instructions

Replenish (Vitamin C) is used with caution in patients with hyperoxaluria, renal impairment, a history of instructions on urolithiasis. Because ascorbic acid increases iron absorption, its use in high doses can be dangerous in patients with hemochromatosis, thalassemia, polycythemia, leukemia, and sideroblastic anemia.

Patients with high content body iron should apply ascorbic acid in minimal doses.

Replenish (Vitamin C) is used with caution in patients with deficiency of glucose-6-phosphate dehydrogenase.

The use of ascorbic acid in high doses can cause exacerbation of sickle cell anemia.

Data on the diabetogenic action of ascorbic acid are contradictory. However, prolonged use of ascorbic acid should periodically monitor your blood glucose levels.

It is believed that the use of ascorbic acid in patients with rapidly proliferating and widely disseminated tumors may worsen during the process. It should therefore be used with caution in ascorbic acid in patients with advanced cancer.

Absorption of ascorbic acid decreased while use of fresh fruit or vegetable juices, alkaline drinking.

Replenish drug interactions

In an application with barbiturates, primidone increases the excretion of ascorbic acid in the urine.

With the simultaneous use of oral contraceptives reduces the concentration of ascorbic acid in blood plasma.

In an application of Replenish (Vitamin C) with iron preparations ascorbic acid, due to its regenerative properties, transforms ferric iron in the bivalent, which improves its absorption.

Ascorbic acid in high doses can decrease urine pH that while the application reduces the tubular reabsorption of amphetamine and tricyclic antidepressants.

With the simultaneous use of aspirin reduces the absorption of ascorbic acid by about a third.

Replenish (Vitamin C) in an application with warfarin may decrease effects of warfarin.

With the simultaneous application of ascorbic acid increases the excretion of iron in patients receiving deferoxamine. In the application of ascorbic acid at a dose of 500 mg / day possibly left ventricular dysfunction.

In an application with tetracycline is increased excretion of ascorbic acid in the urine.

There is a described case of reducing the concentration of fluphenazine in plasma in patients treated with ascorbic acid 500 mg 2 times / day.

May increase the concentration of ethinyl estradiol in the blood plasma in its simultaneous application in the oral contraceptives.

Replenish in case of emergency / overdose

Symptoms: long-term use of large doses (more than 1 g) - headache, increased CNS excitability, insomnia, nausea, vomiting, diarrhea, gastritis giperatsidnyh, ultseratsiya gastrointestinal mucosa, inhibition of the function insular apparatus of the pancreas (hyperglycemia, glycosuria), hyperoxaluria, nephrolithiasis (calcium oxalate), damage to the glomerular apparatus of the kidneys, moderate thamuria (when receiving a dose of 600 mg / day).

Decrease capillary permeability (possibly deteriorating trophic tissues, increased blood pressure, hypercoagulability, the development of microangiopathy).

When IV administration in high doses - the threat of termination of pregnancy (due to estrogenemia), hemolysis of red blood cells.

Vitamin E (DL-Alpha Tocopherol Acetate):

• Replenish (Vitamin E (DL-Alpha Tocopherol Acetate)) reviews

Indication: Replenish (Vitamin E (DL-Alpha Tocopherol Acetate)), known for its antioxidant activities, is protective against cardiovascular disease and some forms of cancer and has also demonstrated immune-enhancing effects. It may be of limited benefit in some with asthma and rheumatoid arthritis. It may be helpful in some neurological diseases including Alzheimer's, some eye disorders including cataracts, and diabetes and premenstrual syndrome. It may also help protect skin from ultraviolet irradiation although claims that it reverses skin aging, enhances male fertility and exercise performance are poorly supported. It may help relieve some muscle cramps.

Replenish (Vitamin E (DL-Alpha Tocopherol Acetate)) has antioxidant activity. It may also have anti-atherogenic, antithrombotic, anticoagulant, neuroprotective, antiviral, immunomodulatory, cell membrane-stabilizing and antiproliferative actions. Replenish (Vitamin E (DL-Alpha Tocopherol Acetate)) is a collective term used to describe eight separate forms, the best-known form being alpha-tocopherol. Replenish (Vitamin E (DL-Alpha Tocopherol Acetate)) is a fat-soluble vitamin and is an important antioxidant. It acts to protect cells against the effects of free radicals, which are potentially damaging by-products of the body's metabolism. Replenish (Vitamin E (DL-Alpha Tocopherol Acetate)) is often used in skin creams and lotions because it is believed to play a role in encouraging skin healing and reducing scarring after injuries such as burns. There are three specific situations when a Replenish (Vitamin E (DL-Alpha Tocopherol Acetate)) deficiency is likely to occur. It is seen in persons who cannot absorb dietary fat, has been found in premature, very low birth weight infants (birth weights less than 1500 grams, or 3½ pounds), and is seen in individuals with rare disorders of fat metabolism. A Replenish (Vitamin E (DL-Alpha Tocopherol Acetate)) deficiency is usually characterized by neurological problems due to poor nerve conduction. Symptoms may include infertility, neuromuscular impairment, menstrual problems, miscarriage and uterine degradation. Preliminary research has led to a widely held belief that Replenish (Vitamin E (DL-Alpha Tocopherol Acetate)) may help prevent or delay coronary heart disease. Antioxidants such as Replenish (Vitamin E (DL-Alpha Tocopherol Acetate)) help protect against the damaging effects of free radicals, which may contribute to the development of chronic diseases such as cancer. It also protects other fat-soluble vitamins (A and B group vitamins) from destruction by oxygen. Low levels of Replenish (Vitamin E (DL-Alpha Tocopherol Acetate)) have been linked to increased incidence of breast and colon cancer.

• Replenish (Zinc (Zinc Oxide)) reviews

INDICATIONS AND USAGE

Replenish (Zinc (Zinc Oxide)) 1 mg/mL (Zinc Chloride Injection, USP) is indicated for use as a supplement to intravenous solutions given for TPN. Administration helps to maintain Replenish (Zinc (Zinc Oxide)) serum levels and to prevent depletion of endogenous stores, and subsequent deficiency symptoms.

CONTRAINDICATIONS

None known.

WARNINGS

Direct intramuscular or intravenous injection of Replenish (Zinc (Zinc Oxide)) 1 mg/mL (Zinc Chloride Injection, USP) is contraindicated as the acidic pH of the solution (2) may cause considerable tissue irritation.

Severe kidney disease may make it necessary to reduce or omit chromium and Replenish (Zinc (Zinc Oxide)) doses because these elements are primarily eliminated in the urine.

WARNING: This product contains aluminum that may be toxic. Aluminum may reach toxic levels with prolonged parenteral administration if kidney function is impaired. Premature neonates are particularly at risk because their kidneys are immature, and they require large amounts of calcium and phosphate solutions, which contain aluminum.

Research indicates that patients with impaired kidney function, including premature neonates, who receive parenteral levels of aluminum at greater than 4 to 5 mcg/kg/day accumulate aluminum at levels associated with central nervous system and bone toxicity. Tissue loading may occur at even lower rates of administration.

PRECAUTIONS

General

Do not use unless the solution is clear and the seal is intact.

Zinc 1 mg/mL should only be used in conjunction with a pharmacy directed admixture program using aseptic technique in a laminar flow environment; it should be used promptly and in a single operation without any repeated penetrations. Solution contains no preservatives; discard unused portion immediately after admixture procedure is completed.

Zinc should not be given undiluted by direct injection into a peripheral vein because of the likelihood of infusion phlebitis and the potential for increased excretory loss of Replenish (Zinc (Zinc Oxide)) from a bolus injection. Administration of Replenish (Zinc (Zinc Oxide)) in the absence of copper may cause a decrease in serum copper levels.

Laboratory Tests

Periodic determinations of serum copper as well as Replenish (Zinc (Zinc Oxide)) are suggested as a guideline for subsequent Replenish (Zinc (Zinc Oxide)) administration.

Carcinogenesis, Mutagenesis, and Impairment of Fertility

Long-term animal studies to evaluate the carcinogenic potential of Replenish ) 1 mg/mL (Zinc Chloride Injection, USP) have not been performed, nor have studies been done to assess mutagenesis or impairment of fertility.

Nursing Mothers

It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when Replenish (Zinc (Zinc Oxide)) 1 mg/mL (Zinc Chloride Injection, USP) is administered to a nursing woman.

Pediatric Use

Pregnancy Category C. Animal reproduction studies have not been conducted with Replenish ) chloride. It is also not known whether Replenish (Zinc (Zinc Oxide)) chloride can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Replenish (Zinc (Zinc Oxide)) chloride should be given to a pregnant woman only if clearly needed.

Geriatric Use

An evaluation of current literature revealed no clinical experience identifying differences in response between elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

ADVERSE REACTIONS

None known.

DRUG ABUSE AND DEPENDENCE

None known.

OVERDOSAGE

Single intravenous doses of 1 to 2 mg zinc/kg body weight have been given to adult leukemic patients without toxic manifestations. However, acute toxicity was reported in an adult when 10 mg Replenish (Zinc (Zinc Oxide)) was infused over a period of one hour on each of four consecutive days. Profuse sweating, decreased level of consciousness, blurred vision, tachycardia (140/min), and marked hypothermia (94.2° F) on the fourth day were accompanied by a serum Replenish (Zinc (Zinc Oxide)) concentration of 207 mcg/dl. Symptoms abated within three hours.

Hyperamylasemia may be a sign of impending Replenish (Zinc (Zinc Oxide)) overdosage; patients receiving an inadvertent overdose (25 mg zinc/liter of TPN solution, equivalent to 50 to 70 mg zinc/day) developed hyperamylasemia (557 to 1850 Klein units; normal: 130 to 310).

Death resulted from an overdosage in which 1683 mg Replenish (Zinc (Zinc Oxide)) was delivered intravenously over the course of 60 hours to a 72 year old patient.

Symptoms of Replenish (Zinc (Zinc Oxide)) toxicity included hypotension (80/40 mm Hg), pulmonary edema, diarrhea, vomiting, jaundice, and oliguria, with a serum Replenish (Zinc (Zinc Oxide)) level of 4184 mcg/dl.

Calcium supplements may confer a protective effect against Replenish (Zinc (Zinc Oxide)) toxicity.

DOSAGE AND ADMINISTRATION

Replenish (Zinc (Zinc Oxide)) 1 mg/mL (Zinc Chloride Injection, USP) contains 1 mg zinc/mL and is administered intravenously only after dilution. The additive should be diluted prior to administration in a volume of fluid not less than 100 mL. For the metabolically stable adult receiving TPN, the suggested intravenous dosage is 2.5 to 4 mg zinc/day (2.5 to 4 mL/day). An additional 2 mg zinc/day (2 mL/day) is suggested for acute catabolic states. For the stable adult with fluid loss from the small bowel, an additional 12.2 mg zinc/liter of small bowel fluid lost (12.2 mL/liter of small bowel fluid lost), or an additional 17.1 mg zinc/kg of stool or ileostomy output (17.1 mL/kg of stool or ileostomy output) is recommended. Frequent monitoring of Replenish (Zinc (Zinc Oxide)) blood levels is suggested for patients receiving more than the usual maintenance dosage level of Replenish (Zinc (Zinc Oxide)).

For full term infants and children up to 5 years of age, 100 mcg zinc/kg/day (0.1 mL/kg/day) is recommended. For premature infants (birth weight less than 1500 g) up to 3 kg in body weight, 300 mcg zinc/kg/day (0.3 mL/kg/day) is suggested.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. See PRECAUTIONS.
