Pidogrel 75 mg is a medication that contains clopidogrel, an antiplatelet agent used to prevent blood clots in patients at risk of cardiovascular events such as heart attack, stroke, or peripheral arterial disease. Clopidogrel works by inhibiting the aggregation of platelets, which are components in the blood that help form clots. By preventing platelets from clumping together, Pidogrel reduces the risk of harmful clot formation in blood vessels, especially in patients who have had recent heart attacks, strokes, or have been diagnosed with coronary artery disease. It is often prescribed in combination with other medications like aspirin, particularly after procedures such as angioplasty or stent placement.
