Cyp450 inhibitor and inducer
WebCYP3A inhibitors, such as azole antifungals, can increase imatinib concentrations; CYP3A inducers, such as rifampin, can decrease imatinib levels, leading to either supra- or subtherapeutic levels of imatinib, respectively (Haouala et al., 2011; Novartis Pharmaceuticals, 2012; FDA, 2011; The Medical Letter of Drugs and Therapeutics, 2011). WebHuman cytochrome P450 (CYP) 3A4 is the most abundant hepatic and intestinal phase I enzyme that metabolizes approximately 50% marketed drugs. The crystal structure of bound and unbound CYP3A4 has been recently constructed, and a small active site and a peripheral binding site are identified.
