Study Summary

The SUGAR-MGH investigators are studying the influence of inherited gene variants on the response to two commonly prescribed type 2 diabetes medications, metformin and glipizide. They hypothesize that variants in genes that are associated with type 2 diabetes or related traits may impact the effect of anti-diabetic medications. In addition, physiological responses to an insulin secretagogue or an insulin sensitizer may shed light on the mechanism of action of reported genetic associations.

Primary Outcome

Investigators will measure glucose levels at 0,30,60,90,120,180 and 240 minutes post 5mg Glipizide administration on Visit 1(Day1), and compare them by genotype at selected loci.
