What is calcium acetate-oral, and how does it work (mechanism of action)?

  • Calcium acetate helps reduce phosphate levels in people with advanced kidney disease.
  • People with advanced kidney failure retain phosphate leading to too much phosphate in their bodies (hyperphosphatemia). High phosphate levels cause hyperparathyroidism, which leads to abnormal bone formation and calcium deposits in tissues.
  • Calcium acetate is a phosphate binder. Calcium acetate, when taken with meals, combines with phosphate in food to form calcium phosphate, which is poorly absorbed into the body and is excreted in the feces.
  • Binding phosphate in the intestines reduces absorption of phosphate into the body.
  • The FDA approved calcium acetate in December 1990.
