Clopidogrel, sold under the brand name Plavix among others, is an antiplatelet medication used to reduce the risk of heart disease and stroke in those at high risk. [10] It is also used together with aspirin in heart attacks and following the placement of a coronary artery stent ( dual antiplatelet therapy ). [ 10 ]
Due to drug-drug interactions, patients taking clopidogrel, an antiplatelet drug, should not take PPI except rabeprazole. [72] Since PPI changes the acidity of the gastric content, patients taking ketoconazole, atazanavir, iron, erlotinib, and MMF should not take PPI at the same time. [72] [73]
Metabolism of ticlopidine, clopidogrel and prasugrel to an active metabolite. Clopidogrel is a prodrug that is metabolized by two pathways. In one of the pathway most of the dose of clopidogrel (85%) is hydrolyzed by esterases to an inactive carboxylic acid derivate and rapidly cleared via glucoridination followed by renal excretion.

Since platelets are involved in the clotting process, patients must take dual antiplatelet therapy starting immediately before or after stenting: usually an ADP receptor antagonist (e.g. clopidogrel or ticagrelor) for up to one year and aspirin indefinitely. [26] [1]
Platelet storage pool deficiency is a family of clotting disorders characterized by deficient granules in platelets.Individuals with these disorders have too few or abnormally functioning alpha granules, delta granules, or both alpha and delta granules and are therefore unable to form effective clots, which leads to prolonged bleeding.
[3] [4] CYP2C19 is a liver enzyme that acts on at least 10% of drugs in current clinical use, [5] most notably the antiplatelet treatment clopidogrel (Plavix), drugs that treat pain associated with ulcers, such as omeprazole, antiseizure drugs such as mephenytoin, the antimalarial proguanil, and the anxiolytic diazepam. [6]
Antiplatelet drugs like clopidogrel and prasugrel irreversibly inhibit the ADP receptor P2Y12, leading to a decreased ADP-induced platelet aggregation. Drugs that inhibit the GPIIb/IIIa receptor, e.g. eptifibatide , can also reduce or eliminate the ADP-induced platelet response.
