1 The 1"-hydroxymidazolam-to-midazolam area under the plasma concentration-time curve ratio was also significantly lower in the CYP3A5*3/*3 group (0.58 +/- 0.35 versus 1.09 +/- 0.37 for the homozygous wild-type group, P =.026). 1-hydroxymethylmidazolam cytochrome P450 family 3 subfamily A member 5 Homo sapiens
2 However, during cytochrome P450 (CYP) 3A inhibition by itraconazole, individuals carrying the CYP3A5*1 allele were found to be less susceptible to changes in systemic clearance and showed higher 1"-hydroxymidazolam-to-midazolam area under the plasma concentration-time curve ratios, probably resulting from the relatively CYP3A4-specific inhibition caused by itraconazole. 1-hydroxymethylmidazolam cytochrome P450 family 3 subfamily A member 5 Homo sapiens
