Calcium Acetate Product Labeling Information

The product labeling information includes all published material associated to a drug. Product labeling documents include information like generic names, active ingredients, ingredient strength dosage, routes of administration, appearance, usage, warnings, inactive ingredients, etc.

Product Labeling Index

1  Indications & Usage

Calcium Acetate Capsules are a phosphate binder indicated to reduce serum phosphorus in patients with end stage renal disease (ESRD).

2  Dosage & Administration

The recommended initial dose of Calcium Acetate Capsules 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 3-4 capsules with each meal.

3  Dosage Forms & Strengths

Capsule:  667 mg calcium acetate per capsules.

4  Contraindications

Patients with hypercalcemia.

5.1 Hypercalcemia

Patients with end stage renal disease may develop hypercalcemia when treated with calcium, including calcium acetate (Calcium Acetate Capsules).  Avoid the use of calcium supplements, including calcium-based nonprescription antacids, concurrently with Calcium Acetate Capsules.An overdose of Calcium Acetate Capsules may lead to progressive hypercalcemia, which may require emergency measures.  Therefore, early in the treatment phase during the dosage adjustment period, monitor serum calcium levels twice weekly.  Should hypercalcemia develop, reduce the Calcium Acetate Capsules 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 Calcium Acetate Capsules 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 Calcium Acetate Capsules 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 Calcium Acetate Capsules 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 a solid dose formulation of calcium acetate; all cases resolved upon lowering the dose or discontinuing treatment.Maintain the serum calcium-phosphorus (Ca x P) product below 55 mg


2/dL

5.2 Concomitant Use With Medications

Hypercalcemia may aggravate digitalis toxicity.

6  Adverse Reactions

Hypercalcemia is discussed elsewhere


[see Warnings and Precautions (5.1)].

6.1 Clinical Trials 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, calcium acetate has been generally well tolerated.Calcium Acetate Capsules were studied in a 3-month, open-label, non-randomized study of 98 enrolled ESRD hemodialysis patients and 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.

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 calcium acetate:  dizziness, edema, and weakness.

7  Drug Interactions

The drug interaction of Calcium Acetate Capsules is characterized by the potential of calcium to bind to drugs with anionic functions (e.g., carboxyl and hydroxyl groups).  Calcium Acetate Capsules may decrease the bioavailability of tetracyclines or fluoroquinolones via this mechanism.There are no empirical data on avoiding drug interactions between calcium acetate or Calcium Acetate Capsules and most concomitant drugs.  When administering an oral medication with Calcium Acetate Capsules 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 Calcium Acetate Capsules or 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 calcium acetate.

7.1 Ciprofloxacin

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

8.1 Pregnancy

Pregnancy Category CCalcium Acetate Capsules contains calcium acetate.  Animal reproduction studies have not been conducted with Calcium Acetate Capsules, and there are no adequate and well controlled studies of Calcium Acetate Capsules use in pregnant women.  Patients with end stage renal disease may develop hypercalcemia with calcium acetate treatment


[see Warnings and Precautions (5.1)].  Maintenance of normal serum 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.  Calcium Acetate Capsules treatment, as recommended, is not expected to harm a fetus if maternal calcium levels are properly monitored during and following treatment.

8.2  Labor & Delivery

The effects of Calcium Acetate Capsules on labor and delivery are unknown.

8.3  Nursing Mothers

Calcium Acetate Capsules contains calcium acetate and is excreted in human milk.  Human milk feeding by a mother receiving Calcium Acetate Capsules is not expected to harm an infant, provided maternal serum 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 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 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.

10  Overdosage

Administration of Calcium Acetate Capsules in excess of the appropriate daily dosage may result in hypercalcemia


[see Warnings and Precautions (5.1)].

12  Clinical Pharmacology

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

12.1  Mechanism Of Action

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

12.2  Pharmacodynamics

Orally administered calcium acetate from pharmaceutical dosage forms is systemically absorbed up to approximately 40% under fasting conditions and up to approximately 30% under non-fasting conditions.  This range represents data from both healthy subjects and renal dialysis patients under various conditions.

13.1  Carcinogenesis & Mutagenesis & Impairment Of Fertility

No carcinogenicity, mutagenicity, or fertility studies have been conducted with calcium acetate.

14  Clinical Studies

Effectiveness of calcium acetate in decreasing serum phosphorus has been demonstrated in two studies of the 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 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 calcium acetate in the treatment of hyperphosphatemia in end-stage renal disease patients.  The effects on serum calcium levels are also presented.
