Clopidogrel is an essential antiplatelet medicine used in acute coronary syndromes and stroke prevention. This article describes its API characteristics for formulators.
What is Clopidogrel Bisulphate API?

Mechanism and Uses
Clopidogrel is a prodrug that irreversibly inhibits the P2Y12 ADP receptor on platelets, reducing platelet aggregation for the lifespan of the platelet. It is commonly used in dual antiplatelet therapy with aspirin following stent implantation and in various acute coronary settings.
Quality and Compliance
Critical quality attributes include control of enantiomeric purity, process‑related impurities, and polymorphic form. Stringent GMP, validated analytical procedures, and comprehensive stability data are required to support marketing in regulated territories.
