WebCytochrome P450 3A (including 3A4) inhibitors and inducers. For drug interaction purposes, the inhibitors and inducers of CYP3A metabolism listed above can alter serum concentrations of drugs that are dependent upon the CYP3A subfamily of liver enzymes, including CYP3A4, for elimination or activation. These classifications are based upon US ... WebInhibition of cytochrome P450 (CYP) and UGT enzymes is a major cause of clinically relevant drug-drug interactions. The inhibitory potential of a test article is assessed by determining its effect on the metabolism of selective probe substrates for human CYP enzymes in pooled human hepatic microsome-based incubations.
