Clopidogrel, sold under the brand name Plavix among others, is an antiplatelet medication used to reduce the risk of heart disease and stroke in those at high risk.[9] It is also used together with aspirin in heart attacks and following the placement of a coronary artery stent (dual antiplatelet therapy).[9] It is taken by mouth.[9] Its effect starts about two hours after intake and lasts for five days.[9]

Common side effects include headache, nausea, easy bruising, itching, and heartburn.[9] More severe side effects include bleeding and thrombotic thrombocytopenic purpura.[9] While there is no evidence of harm from use during pregnancy, such use has not been well studied.[3] Clopidogrel is in the thienopyridine-class of antiplatelets.[9] It works by irreversibly inhibiting a receptor called P2Y12 on platelets.[9]

Clopidogrel was patented in 1982, and approved for medical use in 1997.[6][10] It is on the World Health Organization's List of Essential Medicines.[11] In 2021, it was the 37th most commonly prescribed medication in the United States, with more than 16 million prescriptions.[12][13] It is available as a generic medication.[9]
