Plagrin 75 mg Tablet contains Clopidogrel Bisulfate, an antiplatelet medication that helps prevent blood clots in individuals at high risk of cardiovascular events. It works by irreversibly inhibiting the P2Y12 ADP receptor on platelets, thereby reducing platelet aggregation. This action lowers the risk of heart attacks and strokes, especially in patients with a history of myocardial infarction (MI), stroke, or established peripheral arterial disease
