1 BACKGROUND: Polymorphisms in cytochrome P450 2B6 (CYP2B6) affect the steady state plasma concentration of nevirapine. Nevirapine cytochrome P450 family 2 subfamily B member 6 Homo sapiens
2 BACKGROUND: Polymorphisms in cytochrome P450 2B6 (CYP2B6) affect the steady state plasma concentration of nevirapine. Nevirapine cytochrome P450 family 2 subfamily B member 6 Homo sapiens
3 RESULTS: Women with CYP2B6 516TT genotype (n=9) had higher mean nevirapine plasma levels (14.33 mug/mL) compared to those with heterozygous 516GT (9.18 mug/mL; n=25) and wild- type 516GG (7.95 mug/mL; n=32) genotypes (P=0.01). Nevirapine cytochrome P450 family 2 subfamily B member 6 Homo sapiens
4 Women heterozygous for the CYP2B6 983TC genotype (n=13) had higher mean nevirapine plasma levels (12.94 mug/mL), compared to women with the homozygous 983TT (8.35 mug/mL; n=53) genotype (P=0.007). Nevirapine cytochrome P450 family 2 subfamily B member 6 Homo sapiens
5 CONCLUSIONS: CYP2B6 516G>T and CYP2B6 983T>C genotypes were strongly associated with plasma nevirapine concentration, which predicted immunologic response in women on nevirapine-based antiretroviral therapy. Nevirapine cytochrome P450 family 2 subfamily B member 6 Homo sapiens
6 CONCLUSIONS: CYP2B6 516G>T and CYP2B6 983T>C genotypes were strongly associated with plasma nevirapine concentration, which predicted immunologic response in women on nevirapine-based antiretroviral therapy. Nevirapine cytochrome P450 family 2 subfamily B member 6 Homo sapiens
