Abstract Cytochrome P450 (CYP)-mediated metabolism is the most important mechanism involved in drug clearance, drug-drug interactions, and adverse drug reactions. Mechanism-based inhibition (MBI), also known as time-dependent inhibition (TDI), is a common cause of clinically significant drug interactions and is associated with the formation of reactive metabolites. MBI is characterized by time-, concentration-, and NADPH-dependent inactivation of CYPs, which occurs when a parent drug is bioactivated by the CYP enzyme into a reactive intermediate that then covalently binds to the heme moiety or apoprotein, resulting in irreversible enzyme inactivation. At low substrate concentrations, metabolite formation increases with increasing substrate concentration because enzyme inactivation is minimal. However, at higher substrate concentrations, extensive formation of reactive intermediates leads to rapid and near-complete inactivation of the available |
