Used as an antiplatelet medication to prevent blood clots in patients with acute coronary syndrome, especially those undergoing percutaneous coronary intervention (PCI). It reduces the risk of heart attack, stroke, and cardiovascular death by inhibiting platelet activation and aggregation. Commonly prescribed for patients with unstable angina, myocardial infarction, or those receiving stents. Its rapid onset and consistent effect make it preferred over other antiplatelet drugs in certain high-risk cases.
