  • Adenosine diphosphate receptor inhibitor - Wikipedia

    Adenosine diphosphate receptor inhibitors are a drug class of antiplatelet agents, used in the treatment of acute coronary syndrome (ACS) or in preventive treatment for patients who are in risk of thromboembolism, myocardial infarction or a stroke.These drugs antagonize the P2Y 12 platelet receptors and therefore prevent the binding of ADP to the P2Y 12 receptor.
