Effects of Antidiabetic Medications on the Postprandial State in Prediabetes

Completed · Phase 4 · Has a placebo group

Conditions studied: Prediabetes, Obesity

In brief

This project addresses cardiovascular disease risk in patients with prediabetes. Levels of lipids after eating a meal ("postprandial lipids") are strong independent predictors of cardiovascular risk. Newer anti-diabetic agents - exenatide and saxagliptin - impact lipid metabolism. These medications will be studied for their effect in reducing both postprandial lipid levels and arterial dysfunction.
