Abstract

To evaluate the long-term efficacy, safety, and tolerability of the alpha-glucosidase inhibitor miglitol in the treatment of African-American patients with type 2 diabetes. A total of 345 African-American type 2 diabetic patients (mean age 55.6 years, BMI 31.9 kg/m2, duration of diabetes 4.9 years, baseline HbA1C 8.7%) treated with either diet alone or sulfonylurea were randomized to 1 year of double-blind treatment with either placebo (n = 117) or miglitol (n = 228) at doses of 50 or 100 mg t.i.d., titrated based on tolerability. The primary efficacy criterion was change from baseline in HbA1C at the 6-month visit. Secondarily efficacy parameters included changes from baseline in plasma glucose and serum insulin (both fasting and 120 min after a standardized test meal), fasting lipids, and urinary albumin-to-creatinine ratio. Safety and tolerability evaluations were primarily based on reporting of adverse events and symptoms and on periodic laboratory analyses. Miglitol treatment was associated with a mean placebo-subtracted reduction in HbA1C from baseline of 1.19% at 6 months. Fasting and 120-min postprandial plasma glucose levels were reduced in parallel to HbA1C, in association with miglitol treatment. Significant reductio...Continue Reading
