Clopidogrel is an antiplatelet drug that blocks platelet aggregation. Coagulation occurs due to the adhesion of platelets.

Mode of Action of Clopidogrel Tablet
Clopidogrel is metabolized in our liver, where an enzyme called CYP2C19 activates it in the liver.
Clopidogrel is known to be the active metabolite of thiol.
The thiol metabolite binds to a receptor called P2Y12 that is present on the surface of platelets.
P2Y12 receptor itself signals for platelets to bind, and an enzyme called ADP plays an important role in signaling to this receptor.When clopidogrel binds to this P2Y12 receptor, ADP cannot bind to it and blood clotting does not occur.
One thing to note here is that platelets are not capable of regenerating these receptors.
Therefore, the effect of clopidogrel lasts until the new platelets replace the old platelets.
Therefore, the effect of Clopidogrel lasts 7-10 days. It takes 7-10 days for new platelets to be created.
Therefore, when you stop taking clopidogrel, the effects of clopidogrel persist for several days.
Dosage of Clopidogrel
Patients complaining of heart attack, stroke or angina were given 75 mg once daily, i.e. the OD dose.
