Sitagliptin, an dipeptidyl peptidase-4 inhibitor, does not alter the pharmacokinetics of the sulphonylurea, glyburide, in healthy subjects.

AIMS: Sitagliptin, a dipeptidyl peptidase-4 inhibitor, is an incretin enhancer that is approved for the treatment of Type 2 diabetes. Sitagliptin is mainly renally eliminated and not an inhibitor of CYP450 enzymes in vitro. Glyburide, a sulphonylurea, is an insulin sensitizer and mainly metabolized by CYP2C9. Since both agents may potentially be co-administered, the purpose of this study was to examine the effects of sitagliptin on glyburide pharmacokinetics. METHODS: In this open-label, randomized, two-period crossover study, eight healthy normoglycaemic subjects, 22-44 years old, received single 1.25-mg doses of glyburide alone in one period and co-administered with sitagliptin on day 5 following a multiple-dose regimen for sitagliptin (200-mg q.d. x 6 days) in the other period. RESULTS: The geometric mean ratios and 90% confidence intervals [(glyburide + sitagliptin)/glyburide] for AUC(0-infinity) and C(max) were 1.09 (0.96, 1.24) and 1.01 (0.84, 1.23), respectively. CONCLUSION: Sitagliptin does not alter the pharmacokinetics of glyburide in healthy subjects.[1]
