Calcium Acetate

Calcium Acetate when taken with meals, combines with dietary phosphate to form insoluble Calcium Phosphate which is excreted in the feces. Maintenance of serum phosphorus below 6.0 mg/dl is generally considered as a clinically acceptable outcome of treatment with phosphate binders. Calcium Acetate is highly soluble at neutral pH, making the Calcium readily available for binding to phosphate in the proximal small intestine. Orally administered Calcium Acetate from pharmaceutical dosage forms has been demonstrated to be 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.
