Description
11 DESCRIPTION Calcium acetate acts as a phosphate binder. Its chemical name is calcium acetate. Its molecular formula is C 4 H 6 CaO 4 , and its molecular weight is 158.17. Its structural formula is: Each opaque capsule with a blue cap and white body is spin printed in blue and white ink with “SUVEN” printed on the cap and “667” printed on the body. Each capsule contains 667 mg calcium acetate, USP (anhydrous; Ca(CH 3 COO) 2 ; MW=158.17 grams) equal to 169 mg (8.45 mEq) calcium, and water as the inert binder, crospovidone and sodium stearyl fumarate . The gelatin cap and body have the following inactive ingredients: FD&C blue 1, D&C red 28, titanium dioxide and gelatin. Imprinting ink on capsule body contains shellac and FD&C 2 Aluminum Lake and imprinting ink on capsule cap contains shellac, titanium dioxide and potassium hydroxide. Calcium acetate capsules are administered orally for the control of hyperphosphatemia in end-stage renal failure. FDA approved dissolution test specifications differs from the USP. Structure
What Is Calcium Acetate Capsules 667 Mg Used For?
1 INDICATIONS AND USAGE Calcium acetate is a phosphate binder indicated to reduce serum phosphorus in patients with end stage renal disease (ESRD).
Dosage and Administration
2 DOSAGE AND 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 to 4 capsules with each meal.
Side Effects (Adverse Reactions)
6 ADVERSE REACTIONS Hypercalcemia is discussed elsewhere [see Warnings and Precautions (5.1)] 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, calcium acetate has been generally well tolerated. 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 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. Table 1: Adverse Reactions in Patients with End-Stage Renal Disease Undergoing Hemodialysis Preferred Term Total adverse reactions reported for calcium acetate n=167 n (%) 3-mo, open- label study of calcium acetate n=98 n (%) Double blind, placebo-controlled, cross-over study of liquid calcium acetate n=69 Calcium acetate n (%) Placebo n (%) Nausea 6 (3.6) 6 (6.1) 0 (0.0) 0 (0.0) Vomiting 4 (2.4) 4 (4.1) 0 (0.0) 0 (0.0) Hypercalcemia 21 (12.6) 16 (16.3) 5 (7.2) 0 (0.0) 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 calcium concentration could reduce the incidence and severity of calcium acetate-induced hypercalcemia. Isolated cases pruritus have been reported, which may represent allergic reactions. 6.2 Post marketing 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.
Drug Interactions
7 DRUG INTERACTIONS The drug interaction of calcium acetate is characterized by the potential of calcium to bind to drugs with anionic functions (e.g., carboxyl, and hydroxyl groups). Calcium acetate 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 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 2.7g, decreased the bioavailability of ciprofloxacin by approximately 50%.
Contraindications
4 CONTRAINDICATIONS Patients with hypercalcemia.
Overdosage
10 OVERDOSAGE Administration of calcium acetate in excess of the appropriate daily dosage may result in hypercalcemia [see Warnings and Precautions (5.1)].

What are side effects?
Side effects are unwanted reactions that can occur when taking a medication. They range from mild (headache, nausea) to severe (allergic reactions, organ damage). Not everyone experiences side effects, and severity varies. Report any concerning side effects to your doctor.
What are drug interactions?
Drug interactions occur when a medication is affected by another drug, food, or supplement. Interactions can make medications less effective or cause dangerous side effects. Always tell your doctor about all medications and supplements you take.
