Efficacy of vildagliptin on glucose fluctuation in Japanese type 2 diabetic patients with ongoing sulfonylurea based oral glycemic agent therapy.

Aim: To investigate whether vildagliptin, one of the dipeptidylpeptide-4 (DDP-4) inhibitors, improves not only glycemic control but also glycemic fluctuation when added to ongoing sulfonylurea (SU) based oral hypoglycemic agents (OHA) therapy in patients with type 2 diabetes mellitus (T2DM).

Methods: A total of 19 patients with T2DM were recruited from outpatients. Vildagliptin was initiated with a dose of 100mg per day in the patients who had inadequate glycemic control and glycemic fluctuation with ongoing SU based OHA therapy.
