Clopidogrel is used to prevent heart attacks and strokes in persons with heart disease (recent heart attack), recent stroke, or blood circulation disease (peripheral vascular disease).
It is also used with aspirin to treat new/worsening chest pain (new heart attack, unstable angina) and to keep blood vessels open and prevent blood clots after certain procedures (such as cardiac stent, coronary artery bypass graft-CABG, balloon angioplasty).
It works by blocking certain blood cells called platelets and prevents them from forming harmful blood clots. This "anti-platelet" effect helps keep blood flowing smoothly in your body.
