Brief Summary:
The aims of this study were to investigate the effects of CYP2C9 and CYP2C19 polymorphisms on the pharmacokinetics and pharmacodynamics of glipizide in healthy Chinese subjects.

Condition or disease

Detailed Description:
Compared with CYP2C19, CYP2C9 polymorphism appears to have a dominant role in glipizide pharmacokinetics and pharmacodynamics in vivo. This indicated that dose adjustment based on CYP2C9 genotype may improve antidiabetic treatment.
