Biospecimen Retention:   Samples With DNA

The whole blood samples of each person are stored at -80℃.


Enrollment: 36
Study Start Date: August 2008
Study Completion Date: December 2008
Groups/Cohorts
1
CYP2C9*1/*1 and CYP2C19*1/*1 alleles carrier
2
CYP2C19 PMs (CYP2C19*2/*2, CYP2C19*2/*3 or CYP2C19*3/*3)
3
CYP2C9*1/*3 and CYP2C19*1/*1 alleles carrier

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.
