1 Although methadone N-demethylation is catalyzed in vitro by cytochrome P4502B6 (CYP2B6) and CYP3A4, and clearance in vivo depends on CYP2B6, mechanism(s) of autoinduction are incompletely understood. Methadone cytochrome P450 family 3 subfamily A member 4 Homo sapiens
2 CONCLUSIONS: Methadone caused concentration-dependent autoinduction of methadone N-demethylation in human hepatocytes, related to induction of CYP2B6 and CYP3A4 mRNA expression, protein expression, and catalytic activity. Methadone cytochrome P450 family 3 subfamily A member 4 Homo sapiens
