Calcium Acetate / Magnesium Carbonate
Calcium Acetate/Magnesium Carbonate is a combination phosphate binder used to treat elevated phosphorus levels in patients with chronic kidney disease, particularly those on dialysis. The medication works by binding to dietary phosphate in the gastrointestinal tract, preventing its absorption into the bloodstream.

Treatment of hyperphosphatemia (elevated blood phosphorus levels) in patients with end-stage renal disease on dialysis. It helps manage the mineral and bone disorder associated with chronic kidney disease (CKD-MBD).
Both calcium acetate and magnesium carbonate act as phosphate binders in the GI tract. They bind to dietary phosphate to form insoluble complexes that are excreted in feces, thereby reducing intestinal phosphate absorption and lowering serum phosphorus levels.
Should be taken with meals for maximum effectiveness. Regular monitoring of serum calcium, magnesium, and phosphorus levels is required. Contraindicated in patients with hypercalcemia or hypomagnesemia. May cause GI disturbances. Use with caution in patients with GI disorders. Not recommended for patients with severe renal failure who are not on dialysis due to risk of hypermagnesemia.
