Advantages of α-glucosidase inhibition as monotherapy in elderly type 2 diabetic patients

The objective of this study was to determine the safety, efficacy, and tolerability of the α-glucosidase inhibitor miglitol vs. the sulfonylurea glyburide in the treatment of elderly patients with type 2 diabetes mellitus, inadequately controlled by diet alone. This was a double-blind, randomized, placebo-controlled, 1-yr trial of miglitol 25 mg TID and 50 mg TID compared with placebo and a titrated dose of glyburide in a parallel group comparison study conducted in 30 outpatient sites across the United States. Four hundred eleven (411) diet-treated patients age 60 yr or greater were randomized to receive either placebo TID (n = 101), miglitol 25 mg TID (n = 104), miglitol 50 mg TID (n = 102), or a once-daily dose of glyburide titrated based on fasting plasma glucose (FPG) (n = 104), for a period of 56 weeks. Efficacy was assessed by glycated hemoglobin (HbA1c), fasting and post-meal glucose, insulin, and lipid levels, and by 24-h urinary excretion of glucose and albumin. Safety and tolerability were asse...
