Used primarily as an antiplatelet medication to prevent blood clots in patients with conditions such as heart disease, stroke, and peripheral artery disease. It is often prescribed after heart attacks, stents, or bypass surgery to reduce the risk of further cardiovascular events. Works by inhibiting platelet aggregation, making it effective in preventing thrombotic disorders. Commonly administered in combination with aspirin for enhanced efficacy in certain cases. Also used in the management of acute coronary syndrome and to prevent clot formation in patients with atrial fibrillation who cannot take anticoagulants.
