Clopidogrel is used to prevent blood clots (thrombi) forming in hardened blood vessels (arteries), a process known as atherothrombosis, which can lead to atherothrombotic events such as stroke, heart attack, or death.
Clopidogrel belongs to a class of medicines called antiplatelet. It’s a “blood thinner”. 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.
