Abstract excerpt
Interindividual variability of cytochrome P450 (CYP) 3A inhibition by grapefruit juice was investigated in relation to CYP3A5 and multidrug resistance gene (MDR) 1 genetic polymorphisms in Chinese Han, Uygur, and Kazakh healthy subjects. The measurement of urinary 6 beta-hydroxycortisol/cortisol ratio was used to evaluate CYP3A activity in vivo by high-performance liquid chromatography. CYP3A5*3 and MDR1 C1236T,...
