An Assessment of Pharmacokinetic Gemigliptin and Metformin Interactions in Healthy Mexican Volunteers

Summary

This is an open, randomized (randomization ratio: 1:1), multiple dose, three way, three period cross over study to assess the potential for drug drug interactions between gemigliptin (a DPP-IV inhibitor mainly metabolized by CYP3A4) and metformin in a sample of healthy Mexican volunteers, aimed to determine whether the observed lack of drug-drug interactions between gemigliptin and metformin in the Korean population is reproducible in an ethnically different population characterized by a significant difference in the frequency of CYP3A4 polymorphisms associated with decreased enzymatic activity, such as CYP3A4\*1b, in comparison with Asian populations.
