Thienopyridines are a class of selective, irreversibleADP receptor/P2Y12 inhibitors used for their anti-platelet activity.
Drugs in this class are: clopidogrel (Plavix),prasugrel (Effient), and ticlopidine (Ticlid).
Ticagrelor (Brilinta) is often listed with thienopyridine inhibitors and has similar indications for use but is not a thienopyridine. It is a cyclo-pentyltriazolo-pyrimidine that reversibly inhibits the P2Y12 receptor.
