Thienopyridine

Thienopyridines are a class of selective, irreversible^[1] ADP receptor/P2Y12 inhibitors used for their anti-platelet activity.

Examples

Drugs in this class are: prasugrel (Effient),^[2] ticlopidine (Ticlid), and clopidogrel (Plavix).

Alternatives

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.^[1]
