aspirin + thienopyridine

Aspirin + thienopyridine refers to the combination of aspirin, an antiplatelet agent that irreversibly inhibits cyclooxygenase-1 (COX-1) and thus thromboxane A2 production, with a member of the thienopyridine class (such as clopidogrel or ticlopidine), which irreversibly inhibit the adenosine diphosphate (ADP) P2Y12 receptor on platelets. This dual antiplatelet therapy is widely used to prevent thrombotic events in patients with acute coronary syndromes and after percutaneous coronary intervention with stent placement. The combination targets two key pathways in platelet activation—arachidonate/thromboxane A2 and ADP-mediated aggregation—providing superior protection against clot formation compared to either agent alone[2][3][5]. Commonly used thienopyridines include clopidogrel and ticlopidine.
