What is the excipient profile of BONJESTA?
BONJESTA (zoledronic acid) is a prescription medication used for osteoporosis and Paget’s disease. Its formulation includes specific excipients to enhance stability, bioavailability, and patient compliance. The composition typically involves stabilizers, buffers, and solubilizers to facilitate intravenous administration.
Common excipients in BONJESTA formulations:
- Mannitol: Acts as a stabilizer and diluent.
- Water for injections: Solvent.
- Sodium citrate: Buffers the solution to maintain pH.
- Edetate disodium: Chelating agent to stabilize the solution.
Given the intravenous route, excipient toxicity, compatibility, and stability are critical in formulation development.
