DRUGS & SUPPLEMENTS
Osex Forte usesOsex Forte consists of Calcium, Phosphorus, Zinc Sulfate.
1 INDICATIONS AND USAGE
Osex Forte (Calcium) acetate is a phosphate binder indicated to reduce serum phosphorus in patients with end stage renal disease (ESRD).
- 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 Osex Forte (Calcium) 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 Osex Forte (Calcium) acetate capsule.
- Capsule: 667 mg Osex Forte (Calcium) acetate capsule. (3)
Patients with hypercalcemia.
- Hypercalcemia. (4)
5 WARNINGS AND PRECAUTIONS
- Treat mild hypercalcemia by reducing or interrupting Osex Forte acetate and Vitamin D. Severe hypercalcemia may require hemodialysis and discontinuation of Osex Forte (Calcium) acetate. (5.1)
- Hypercalcemia may aggravate digitalis toxicity. (5.2)
Patients with end stage renal disease may develop hypercalcemia when treated with Osex Forte (Calcium), including Osex Forte (Calcium) acetate. Avoid the use of Osex Forte (Calcium) supplements, including Osex Forte (Calcium) based nonprescription antacids, concurrently with Osex Forte (Calcium) acetate.
An overdose of Osex Forte (Calcium) acetate may lead to progressive hypercalcemia, which may require emergency measures. Therefore, early in the treatment phase during the dosage adjustment period, monitor serum Osex Forte (Calcium) levels twice weekly. Should hypercalcemia develop, reduce the Osex Forte (Calcium) 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 Osex Forte (Calcium) 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 Osex Forte (Calcium) 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 Osex Forte (Calcium) 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 Osex Forte (Calcium) 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 Osex Forte (Calcium) 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, Osex Forte (Calcium) acetate has been generally well tolerated.
Osex Forte (Calcium) acetate was studied in a 3 month, open-label, non-randomized study of 98 enrolled ESRD hemodialysis patients and an alternate liquid formulation of Osex Forte (Calcium) 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 Osex Forte (Calcium) concentration could reduce the incidence and severity of Osex Forte (Calcium) 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 Osex Forte (Calcium) acetate: dizziness, edema, and weakness.
7 DRUG INTERACTIONS
The drug interaction of Osex Forte acetate is characterized by the potential of Osex Forte (Calcium) to bind to drugs with anionic functions (e.g., carboxyl, and hydroxyl groups). Osex Forte (Calcium) acetate may decrease the bioavailability of tetracyclines or fluoroquinolones via this mechanism.
There are no empirical data on avoiding drug interactions between Osex Forte (Calcium) acetate and most concomitant drugs. When administering an oral medication with Osex Forte (Calcium) 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 Osex Forte (Calcium) 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 Osex Forte (Calcium) 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 Osex Forte (Calcium) acetate or consider monitoring blood levels of the drug. (7)
In a study of 15 healthy subjects, a co-administered single dose of 4 Osex Forte (Calcium) acetate tablets, approximately 2.7g, decreased the bioavailability of ciprofloxacin by approximately 50%.
8 USE IN SPECIFIC POPULATIONS
Pregnancy Category C:
Osex Forte acetate capsules contains Osex Forte (Calcium) acetate. Animal reproduction studies have not been conducted with Osex Forte (Calcium) acetate, and there are no adequate and well controlled studies of Osex Forte (Calcium) acetate use in pregnant women. Patients with end stage renal disease may develop hypercalcemia with Osex Forte (Calcium) acetate treatment [see Warnings and Precautions (5.1 ) ]. Maintenance of normal serum Osex Forte (Calcium) 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. Osex Forte (Calcium) acetate treatment, as recommended, is not expected to harm a fetus if maternal Osex Forte (Calcium) levels are properly monitored during and following treatment.
8.2 Labor and Delivery
The effects of Osex Forte (Calcium) acetate on labor and delivery are unknown.
8.3 Nursing Mothers
Osex Forte Acetate Capsules contains Osex Forte (Calcium) acetate and is excreted in human milk. Human milk feeding by a mother receiving Osex Forte (Calcium) acetate is not expected to harm an infant, provided maternal serum Osex Forte (Calcium) 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 Osex Forte (Calcium) 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.
Administration of Osex Forte (Calcium) acetate in excess of the appropriate daily dosage may result in hypercalcemia [see Warnings and Precautions (5.1)].
Osex Forte (Calcium) acetate acts as a phosphate binder. Its chemical name is Osex Forte (Calcium) 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 Osex Forte (Calcium) acetate USP (anhydrous; Ca(CH3COO)2; MW=158.17 grams) equal to 169 mg (8.45 mEq) Osex Forte (Calcium), 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.
Osex Forte (Calcium) Acetate Capsules are administered orally for the control of hyperphosphatemia in end-stage renal failure.
12 CLINICAL PHARMACOLOGY
Patients with ESRD retain phosphorus and can develop hyperphosphatemia. High serum phosphorus can precipitate serum Osex Forte resulting in ectopic calcification. Hyperphosphatemia also plays a role in the development of secondary hyperparathyroidism in patients with ESRD.
12.1 Mechanism of Action
Osex Forte (Calcium) acetate, when taken with meals, combines with dietary phosphate to form an insoluble Osex Forte (Calcium) phosphate complex, which is excreted in the feces, resulting in decreased serum phosphorus concentration.
Orally administered Osex Forte (Calcium) 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 Osex Forte (Calcium) acetate.
14 CLINICAL STUDIES
Effectiveness of Osex Forte (Calcium) acetate in decreasing serum phosphorus has been demonstrated in two studies of the Osex Forte (Calcium) 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 Osex Forte (Calcium) 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 Osex Forte (Calcium) acetate in the treatment of hyperphosphatemia in end-stage renal disease patients. The effects on serum Osex Forte (Calcium) 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 Osex Forte (Calcium) 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 Osex Forte (Calcium) 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 Osex Forte (Calcium) acetate is shown in the Table 3.
Overall, 2 weeks of treatment with Osex Forte (Calcium) acetate statistically significantly (p<0.01) decreased serum phosphorus by a mean of 19% and increased serum Osex Forte (Calcium) by a statistically significant (p<0.01) but clinically unimportant mean of 7%.

INDICATIONS AND USAGE
Osex Forte (Zinc Sulfate) 1 mg/mL (Zinc Chloride Injection, USP) is indicated for use as a supplement to intravenous solutions given for TPN. Administration helps to maintain Osex Forte (Zinc Sulfate) serum levels and to prevent depletion of endogenous stores, and subsequent deficiency symptoms.
Direct intramuscular or intravenous injection of Osex Forte (Zinc Sulfate) 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 Osex Forte (Zinc Sulfate) 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.
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 Osex Forte (Zinc Sulfate) from a bolus injection. Administration of Osex Forte (Zinc Sulfate) in the absence of copper may cause a decrease in serum copper levels.
Periodic determinations of serum copper as well as Osex Forte (Zinc Sulfate) are suggested as a guideline for subsequent Osex Forte (Zinc Sulfate) administration.
Carcinogenesis, Mutagenesis, and Impairment of Fertility
Long-term animal studies to evaluate the carcinogenic potential of Osex Forte 1 mg/mL (Zinc Chloride Injection, USP) have not been performed, nor have studies been done to assess mutagenesis or impairment of fertility.
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 Osex Forte (Zinc Sulfate) 1 mg/mL (Zinc Chloride Injection, USP) is administered to a nursing woman.
Pregnancy Category C. Animal reproduction studies have not been conducted with Osex Forte chloride. It is also not known whether Osex Forte (Zinc Sulfate) chloride can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Osex Forte (Zinc Sulfate) chloride should be given to a pregnant woman only if clearly needed.
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.
DRUG ABUSE AND DEPENDENCE
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 Osex Forte (Zinc Sulfate) 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 Osex Forte (Zinc Sulfate) concentration of 207 mcg/dl. Symptoms abated within three hours.
Hyperamylasemia may be a sign of impending Osex Forte (Zinc Sulfate) 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 Osex Forte (Zinc Sulfate) was delivered intravenously over the course of 60 hours to a 72 year old patient.
Symptoms of Osex Forte (Zinc Sulfate) toxicity included hypotension (80/40 mm Hg), pulmonary edema, diarrhea, vomiting, jaundice, and oliguria, with a serum Osex Forte (Zinc Sulfate) level of 4184 mcg/dl.
Calcium supplements may confer a protective effect against Osex Forte (Zinc Sulfate) toxicity.
DOSAGE AND ADMINISTRATION
Osex Forte (Zinc Sulfate) 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 Osex Forte (Zinc Sulfate) blood levels is suggested for patients receiving more than the usual maintenance dosage level of Osex Forte (Zinc Sulfate).
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.
Osex Forte (Zinc Sulfate) 1 mg/mL (Zinc Chloride Injection, USP) is supplied in 10 mL Plastic Vials (List No. 4090).
