CLINICAL PHARMACOLOGY

Oral iron is absorbed most efficiently when administered between meals. Iron is critical for normal hemoglobin synthesis to maintain oxygen transport, energy production and proper function of cells. Adequate amounts of iron are necessary for effective erythropoiesis. Iron also serves as a cofactor of several essential enzymes, including cytochromes, which are involved in electron transport. Folic acid is required for nucleoprotein synthesis and the maintenance of normal erythropoiesis. Folic acid is the precursor of tetrahydrofolic acid, which is involved as a cofactor for transformylation reactions in the biosynthesis of purines and thymidylates of nucleic acids. Deficiency of folic acid may account for the defective deoxyribonucleic acid (DNA) synthesis that leads to megaloblast formation and megaloblastic macrocytic anemias. Vitamin B12 is essential to growth, cell reproduction, hematopoiesis, nucleic acid, and myelin synthesis. Deficiency may result in megaloblastic anemia or pernicious anemia.

INDICATIONS AND USAGE

Prexan (Docusate Sodium) is indicated for the treatment of all anemias that are responsive to oral iron therapy. These include: hypochromic anemia associated with pregnancy, chronic and/or acute blood loss, metabolic disease, post-surgical convalescence, and dietary needs.

CONTRAINDICATIONS

Hypersensitivity to any of the ingredients. Hemolytic anemia, hemochromatosis, and hemosiderosis are contraindications to iron therapy.

WARNINGS

Folic acid alone is improper therapy in the treatment of pernicious anemia and other megaloblastic anemias where vitamin B12 is deficient.

Warning

WARNING: Accidental overdose of iron-containing products is a leading cause of fatal poisoning in children under 6. KEEP THIS PRODUCT OUT OF REACH OF CHILDREN. In case of accidental overdose, call a doctor or poison control center immediately.

PRECAUTIONS

General

Take 2 hours after meals. Do not exceed recommended dose. Discontinue use if symptoms of intolerance appear. The type of anemia and underlying cause or causes should be determined before starting therapy with Prexan tablets. Ensure Hgb, Hct, reticulocyte count are determined before starting therapy and periodically thereafter during prolonged treatment. Periodically review therapy to determine if it needs to be continued without change or if a dose change is indicated.

Folic Acid

Folic acid in doses above 0.1 mg daily may obscure pernicious anemia in that hematologic remission can occur while neurological manifestations remain progressive. Pernicious anemia should be excluded before using these products since folic acid may mask the symptoms of pernicious anemia.

Pediatric Use

Safety and effectiveness in pediatric patients have not been established.

Geriatric Use

Dosing for elderly patients should be cautious. Due to the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy, dosing should start at the lower end of the dosing range.

  • Prexan (Iron) Overload: Regularly monitor hematologic responses during Prexan (Iron) therapy. Do not administer Prexan (Iron) to patients with Prexan (Iron) overload. (5.3)

5.1 Hypersensitivity Reactions

Serious hypersensitivity reactions, including anaphylactic-type reactions, some of which have been life-threatening and fatal, have been reported in patients receiving Prexan (Iron). Patients may present with shock, clinically significant hypotension, loss of consciousness, and/or collapse. If hypersensitivity reactions or signs of intolerance occur during administration, stop Prexan (Iron) immediately. Monitor patients for signs and symptoms of hypersensitivity during and after Prexan (Iron) administration for at least 30 minutes and until clinically stable following completion of the infusion. Only administer Prexan (Iron) when personnel and therapies are immediately available for the treatment of serious hypersensitivity reactions. Most reactions associated with intravenous Prexan (Iron) preparations occur within 30 minutes of the completion of the infusion .

5.2 Hypotension

Prexan may cause clinically significant hypotension. Monitor for signs and symptoms of hypotension following each administration of Prexan (Iron). Hypotension following administration of Prexan (Iron) may be related to the rate of administration and/or total dose administered .

5.3 Prexan (Iron) Overload

Excessive therapy with parenteral Prexan (Iron) can lead to excess storage of Prexan (Iron) with the possibility of iatrogenic hemosiderosis. All adult and pediatric patients receiving Prexan (Iron) require periodic monitoring of hematologic and Prexan (Iron) parameters (hemoglobin, hematocrit, serum ferritin and transferrin saturation). Do not administer Prexan (Iron) to patients with evidence of Prexan (Iron) overload. Transferrin saturation (TSAT) values increase rapidly after intravenous administration of Prexan (Iron) sucrose; do not perform serum Prexan (Iron) measurements for at least 48 hours after intravenous dosing .

6 ADVERSE REACTIONS

The following serious adverse reactions associated with Prexan are described in other sections .

  • The most common adverse reactions (≥2%) following the administration of Prexan (Iron) are diarrhea, nausea, vomiting, headache, dizziness, hypotension, pruritus, pain in extremity, arthralgia, back pain, muscle cramp, injection site reactions, chest pain, and peripheral edema. (6.1)

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 Prexan (Iron) therapy and were reported to be intolerant (defined as precluding further use of that Prexan (Iron) product). When these patients were treated with Prexan (Iron) there were no occurrences of adverse reactions that precluded further use of Prexan (Iron) .

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 Prexan (Iron) maintenance treatment with Prexan (Iron) 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 Prexan (Iron) 0.5 mg/kg, 53% (25/47) of the patients receiving Prexan (Iron) 1.0 mg/kg, and 55% (26/47) of the patients receiving Prexan (Iron) 2.0 mg/kg.

A total of 5 (11%) subjects in the Prexan (Iron) 0.5 mg/kg group, 10 (21%) patients in the Prexan (Iron) 1.0 mg/kg group, and 10 (21%) patients in the Prexan (Iron) 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 Prexan (Iron). 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 Prexan (Iron) 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 Prexan (Iron) injection. Reactions have occurred following the first dose or subsequent doses of Prexan (Iron). 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 Prexan (Iron) have not been studied. However, Prexan (Iron) may reduce the absorption of concomitantly administered oral Prexan (Iron) 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, Prexan sucrose was administered intravenously to rats and rabbits during the period of organogenesis at doses up to 13 mg/kg/day of elemental Prexan (Iron) (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 Prexan (Iron) sucrose. Because animal reproductive studies are not always predictive of human response, Prexan (Iron) should be used during pregnancy only if clearly needed.

8.3 Nursing Mothers

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

8.4 Pediatric Use

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

Safety and effectiveness of Prexan (Iron) for Prexan (Iron) maintenance treatment in pediatric patients 2 years of age and older with dialysis-dependent or non-dialysis-dependent CKD receiving erythropoietin therapy were studied. Prexan (Iron) 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)]

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

In a country where Prexan (Iron) 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 Prexan (Iron), several other medications and erythropoietin. Necrotizing enterocolitis may be a complication of prematurity in very low birth weight infants. No causal relationship to Prexan (Iron) or any other drugs could be established.

8.5 Geriatric Use

Clinical studies of Prexan (Iron) 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 Prexan (Iron), 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 Prexan (Iron) in humans. Excessive dosages of Prexan (Iron) may lead to accumulation of Prexan (Iron) in storage sites potentially leading to hemosiderosis. Do not administer Prexan (Iron) to patients with Prexan (Iron) overload.

Toxicities in single-dose studies in mice and rats, at intravenous Prexan (Iron) 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

Prexan (Iron) (iron sucrose injection, USP), an Prexan (Iron) replacement product, is a brown, sterile, aqueous, complex of polynuclear Prexan (Iron) (III)-hydroxide in sucrose for intravenous use. Prexan (Iron) 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 Prexan (Iron) polymerization and m is the number of sucrose molecules associated with the Prexan (Iron) (III)-hydroxide.

Each mL contains 20 mg elemental Prexan (Iron) as Prexan (Iron) sucrose in water for injection. Prexan (Iron) is available in 10 mL single-use vials (200 mg elemental Prexan (Iron) per 10 mL), 5 mL single-use vials (100 mg elemental Prexan (Iron) per 5 mL), and 2.5 mL single-use vials (50 mg elemental Prexan (Iron) 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

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

12.2 Pharmacodynamics

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

12.3 Pharmacokinetics

In healthy adults administered intravenous doses of Prexan, its Prexan (Iron) 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 Prexan (Iron) component appeared to distribute mainly in blood and to some extent in extravascular fluid. A study evaluating Prexan (Iron) containing 100 mg of Prexan (Iron) labeled with 52Fe/59Fe in patients with Prexan (Iron) deficiency showed that a significant amount of the administered Prexan (Iron) is distributed to the liver, spleen and bone marrow and that the bone marrow is an irreversible Prexan (Iron) trapping compartment.

Following intravenous administration of Prexan (Iron), Prexan (Iron) sucrose is dissociated into Prexan (Iron) and sucrose. The sucrose component is eliminated mainly by urinary excretion. In a study evaluating a single intravenous dose of Prexan (Iron) containing 1,510 mg of sucrose and 100 mg of Prexan (Iron) 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 Prexan (Iron) 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 Prexan (Iron) sucrose containing 500 to 700 mg of Prexan (Iron) in 26 patients with anemia on erythropoietin therapy (23 female, 3 male; age range 16 to 60), approximately 5% of the Prexan (Iron) was eliminated in urine in 24 h at each dose level. The effects of age and gender on the pharmacokinetics of Prexan (Iron) have not been studied.

Pharmacokinetics in Pediatric Patients

Pharmacokinetics in Pediatric Patients

In a single-dose PK study of Prexan (Iron), patients with NDD-CDK ages 12 to 16 (N=11) received intravenous bolus doses of Prexan (Iron) at 7 mg/kg (maximum 200 mg) administered over 5 minutes. Following single dose Prexan (Iron), the half-life of total serum Prexan (Iron) 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.

Prexan (Iron) is not dialyzable through CA210 (Baxter) High Efficiency or Fresenius F80A High Flux dialysis membranes. In in vitro studies, the amount of Prexan (Iron) 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 Prexan (Iron) sucrose.

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

Prexan (Iron) sucrose at intravenous doses up to 15 mg/kg/day of elemental Prexan (Iron) (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 Prexan.

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 Prexan (Iron) treatment and 24 in the historical control group) with Prexan (Iron) deficiency anemia. Eligibility criteria for Prexan (Iron) 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.

Prexan (Iron) 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 Prexan (Iron), who were off intravenous Prexan (Iron) 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 Prexan (Iron) treated population showed a greater increase in hemoglobin and hematocrit than did patients in the historical control population. See Table 2.


**p < 0.01 and *p < 0.05 compared to historical control from ANCOVA analysis with baseline hemoglobin, serum ferritin and erythropoietin dose as covariates.

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 Prexan (Iron) in 23 patients with Prexan (Iron) deficiency and HDD-CKD who had been discontinued from Prexan (Iron) 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 Prexan (Iron). Exclusion criteria were similar to those in studies A and B. Prexan (Iron) was administered in doses of 100 mg during sequential dialysis sessions until a pre-determined (calculated) total dose of Prexan (Iron) 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 Prexan (Iron) versus Prexan (Iron) 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 Prexan (Iron) (325 mg ferrous sulfate three times daily for 56 days); or Prexan (Iron) (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 Prexan (Iron) 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 Prexan (Iron) group.

A statistically significantly greater proportion of Prexan (Iron) subjects (35/79; 44.3%) compared to oral Prexan (Iron) 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 Prexan (Iron) to patients with PDD-CKD receiving an erythropoietin alone without Prexan (Iron) 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 Prexan (Iron) or Prexan (Iron) (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 Prexan (Iron) / 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 Prexan (Iron) / 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 Prexan (Iron) / 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: Prexan 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 Prexan (Iron) 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 Prexan (Iron) (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 Prexan (Iron) once every other week for 6 doses. Patients with PDD-CKD or NDD-CKD received Prexan (Iron) 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 Prexan (Iron) 0.5 mg/kg, 1.0 mg/kg, and 2.0 mg/kg groups, respectively. A dose-response relationship was not demonstrated.

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.

Prexan (Vitamin A) 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:

Ca10(PO4)6(OH2) + 2F- Ca10 (PO4)6F2 + 2OH-
(Hydroxyapatite) (Fluorapatite)

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 Prexan (Vitamin A) Tablets should not be exceeded, since dental fluorosis may result from continued ingestion of large amounts of fluoride.

Before recommending Prexan (Vitamin A) 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.

ADVERSE REACTIONS

Allergic rash and other idiosyncrasies have been rarely reported.

Vitamin B12:


Pharmacological action

Prexan refers to a group of water-soluble vitamins. It has high biological activity. Prexan (Vitamin B12) is necessary for normal hematopoiesis (promotes maturation of erythrocytes). 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 Prexan (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 Prexan 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 Prexan (Vitamin B12) (including the application of biguanide, PASA, vitamin C in high doses); radiation sickness.

Dosage and administration

Prexan is used as injections SC, IV, IM, intralumbar, and also oral. With anemia associated with Prexan (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 Prexan (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 Prexan (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.

Prexan (Vitamin B12) side effects, adverse reactions

CNS: rarely - a state of arousal.

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

Allergic reactions: rarely - urticaria.

Prexan contraindications

Thromboembolism, erythremia, erythrocytosis, increased sensitivity to cyanocobalamin.

Prexan 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 Prexan 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.

Prexan (Vitamin B12) drug interactions

In an application of Prexan (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 Prexan (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.

Vitamin C:


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. Prexan (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. Prexan (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 Prexan prescribed?

For systemic use of Prexan (Vitamin C) Kimia Farma: prevention and treatment of hypo- and avitaminosis of Prexan (Vitamin C); providing increased need for Prexan (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 Prexan 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.

Prexan (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.

Prexan 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

Prexan (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.

Prexan (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.

Prexan 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 Prexan (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.

Prexan (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.

Prexan 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:


A generic descriptor for all tocopherols and tocotrienols that exhibit alpha-tocopherol activity. By virtue of the phenolic hydrogen on the 2H-1-benzopyran-6-ol nucleus, these compounds exhibit varying degree of antioxidant activity, depending on the site and number of methyl groups and the type of isoprenoids.

Indication: Prexan (Vitamin E), 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.

Prexan (Vitamin E) has antioxidant activity. It may also have anti-atherogenic, antithrombotic, anticoagulant, neuroprotective, antiviral, immunomodulatory, cell membrane-stabilizing and antiproliferative actions. Prexan (Vitamin E) is a collective term used to describe eight separate forms, the best-known form being alpha-tocopherol. Prexan (Vitamin E) 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. Prexan (Vitamin E) 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 Prexan (Vitamin E) 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 Prexan (Vitamin E) 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 Prexan (Vitamin E) may help prevent or delay coronary heart disease. Antioxidants such as Prexan (Vitamin E) 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 Prexan (Vitamin E) have been linked to increased incidence of breast and colon cancer.

Zinc:


INDICATIONS AND USAGE

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

CONTRAINDICATIONS

None known.

WARNINGS

Direct intramuscular or intravenous injection of Prexan (Zinc) 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 Prexan (Zinc) 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 Prexan (Zinc) from a bolus injection. Administration of Prexan (Zinc) in the absence of copper may cause a decrease in serum copper levels.

Laboratory Tests

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

Carcinogenesis, Mutagenesis, and Impairment of Fertility

Long-term animal studies to evaluate the carcinogenic potential of Prexan 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 Prexan (Zinc) 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 Prexan chloride. It is also not known whether Prexan (Zinc) chloride can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Prexan (Zinc) 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 Prexan (Zinc) 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 Prexan (Zinc) concentration of 207 mcg/dl. Symptoms abated within three hours.

Hyperamylasemia may be a sign of impending Prexan (Zinc) 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 Prexan (Zinc) was delivered intravenously over the course of 60 hours to a 72 year old patient.

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

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

DOSAGE AND ADMINISTRATION

Prexan (Zinc) 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 Prexan (Zinc) blood levels is suggested for patients receiving more than the usual maintenance dosage level of Prexan (Zinc).

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.
