Population Estimation of the Effects of Cytochrome P450 2C9 and 2C19 Polymorphisms on Phenobarbital Clearance in Japanese
1 Feb 2007
Abstract excerpt
A nonlinear mixed-effect modeling (NONMEM) program was used to evaluate the effects of cytochrome P450 (CYP) 2C9 and CYP2C19 polymorphisms on the phenobarbital (PB) population clearance for Japanese epileptics.

The covariates...
