Methadone 102-111 cytochrome P450 family 2 subfamily B member 6 Homo sapiens 19-25 28723731-2 2017 The aim of this study was to clarify the impact of the reduced function CYP2B6*6 variant allele together with variants in other candidate genes on a steady-state methadone concentration in a naturalistic setting. Methadone 162-171 cytochrome P450 family 2 subfamily B member 6 Homo sapiens 72-78 28723731-6 2017 The estimated mean methadone C/D ratios was 17.8 nmol L mg for homozygous carriers of CYP2B6*6, which was significantly (P < 0.001) higher than noncarriers (9.2 nmol L mg). Methadone 19-28 cytochrome P450 family 2 subfamily B member 6 Homo sapiens 86-92 28723731-9 2017 CONCLUSIONS: Patients homozygous for CYP2B6*6 had a >90% higher methadone C/D ratio. Methadone 67-76 cytochrome P450 family 2 subfamily B member 6 Homo sapiens 37-43 28723731-10 2017 Genotyping of CYP2B6 may therefore be of value when assessing dose requirements in methadone maintenance treatment.
