Mechanism of action

Thienopyridines are antiplatelet agents that irreversibly bind to the P2Y12 receptor, preventing adenosine diphosphate (ADP)-induced platelet activation and aggregation. This mechanism reduces thrombotic events by inhibiting platelet clumping and clot formation. They are commonly used to prevent stent thrombosis and reduce cardiovascular events in patients with acute coronary syndromes or undergoing percutaneous coronary intervention.
