Pathway Description
Clopidogrel Metabolic Pathway
Homo sapiens
Metabolic Pathway
85-90% of an oral dose undergoes first pass metabolism by carboxylesterase 1 in the liver to an inactive carboxylic acid metabolite. About 2% of clopidogrel is oxidized to 2-oxoclopidogrel. This conversion is 35.8% by CYP1A2, 19.4% by CYP2B6, and 44.9% by CYP2C194 though other studies suggest CYP3A4, CYP3A5, and CYP2C9 also contribute. 2-oxoclopidogrel is further metabolized to the active metabolite. This conversion is 32.9% by CYP2B6, 6.79% by CYP2C9, 20.6% by CYP2C19, and 39.8% by CYP3A4.
