What role does calcium acetate play as an excipient in pharmaceuticals?
Calcium acetate functions primarily as a buffering agent, binding agent, or electrolyte replenisher in drug formulations. It is used to stabilize pH, improve drug stability, or facilitate controlled release. Its solubility in water and favorable safety profile make it suitable for oral, injectable, and topical formulations.
How is calcium acetate utilized in pharmaceutical formulations?
Calcium acetate's applications include:
- Dialysis solutions: Acts as a phosphate binder to reduce serum phosphate in patients with chronic kidney disease.
- Oral medications: Forms part of antacids or phosphate binder formulations used to manage hyperphosphatemia.
- Injectable preparations: Used in calcium supplementation or in electrolyte therapy.
- Topicals and creams: Serves as a pH stabilizer or buffering agent.
What is calcium acetate’s current market landscape?
Global demand estimates reached approximately 2,000 metric tons in 2022, driven mainly by medical indications such as dialysis and phosphate control.
