Clopidogrel mechanism involves which action?

• A. Competes with ADP, affecting Platelet Activation
• B. Inhibits COX-1
• C. Inhibits platelet production
• D. Enhances platelet aggregation

Answer: (A)

Clopidogrel works by blocking the ADP receptor on platelets, preventing ADP from activating them and promoting aggregation. It’s a prodrug that is metabolized in the liver to an active form that irreversibly binds to the P2Y12 receptor, so the inhibition lasts for the platelet’s lifetime. This mechanism is distinct from aspirin, which inhibits COX-1. It does not inhibit platelet production, nor does it enhance aggregation; it specifically dampens ADP-driven platelet activation to reduce clot formation.
