Antiplatelet drugs - P2Y12 inhibitors
Platelets are small cells in your blood that your body uses to form clots and stop bleeding. If you have too many platelets or your platelets stick together too much, you are more likely to form clots. This clotting can take place on the inside of your arteries and lead to heart attack or stroke.
Antiplatelet drugs work to make your platelets less sticky and thereby help prevent blood clots from forming in your arteries.
Blood thinners - clopidogrel; Antiplatelet therapy - clopidogrel; Thienopyridines
