Witryna10 lip 2012 · It is well established that genetic polymorphisms that exist within drug transporters and drug metabolizing enzymes have a role in determining the … WitrynaConclusion: Genetic variation in a combination of SULT1A1*2 and SULT1A1 copy number may contribute to variability in EFV metabolism and thereby may impact drug response. The influence of a combination between the SULT1A1 and CYP2B6 genotype on EFV pharmacokinetics should be further investigated in a larger study population.
