Comparison of Acarbose and Voglibose in Diabetes Patients Who Are Inadequately Controlled with Basal Insulin Treatment: Randomized, Parallel, Open-Label, Active-Controlled Study

초록

We studied the efficacy and safety of acarbose in comparison with voglibose in type 2 diabetes patients whose blood glucose levels were inadequately controlled with basal insulin alone or in combination with metformin (or a sulfonylurea). This study was a 24-week prospective, open-label, randomized, active-controlled multi-center study. Participants were randomized to receive either acarbose (n= 59, 300 mg/day) or voglibose (n = 62, 0.9 mg/day). The mean HbA(1c) at week 24 was significantly decreased approximately 0.7% from baseline in both acarbose (from 8.43% +/- 0.71% to 7.71% +/- 0.93%) and voglibose groups (from 8.38% +/- 0.73% to 7.68% +/- 0.94%). The mean fasting plasma glucose level and self-monitoring of blood glucose data from 1 hr before and after each meal were significantly decreased at week 24 in comparison to baseline in both groups. The levels 1 hr after dinner at week 24 were significantly decreased in the acarbose group (from 233.54 +/- 69.38 to 176.80 +/- 46.63 mg/dL) compared with the voglibose group (from 224.18 +/- 70.07 to 193.01 +/- 55.39 mg/dL). In conclusion, both acarbose and voglibose are efficacious and safe in patients with type 2 diabetes who are inadequately controlled with basal insulin.
