1 Recombinant CYP3A4 and CYP3A5 (rCYP3A4 and rCYP3A5) both produced 1-OH and 4-OH metabolites from midazolam and triazolam, 6 beta-hydroxytestosterone from testosterone, and oxidized nifedipine from nifedipine. Triazolam cytochrome P450 family 3 subfamily A member 5 Homo sapiens
2 Thus, CYP3A4 and CYP3A5 both contribute to midazolam, triazolam, testosterone, and nifedipine biotransformation in HLMs, with CYP3A5 being metabolically less active than CYP3A4 in general. Triazolam cytochrome P450 family 3 subfamily A member 5 Homo sapiens
