Abstract
In this double-blind, cross-over, placebo-controlled, randomized study, possible extraintestinal effects of miglitol, an absorbable α-glucosidase inhibitor, were investigated. Sixteen healthy male volunteers underwent two 75 g oral glucose tolerance tests with concomitant administration of miglitol or placebo. Peak and post-peak areas under the curve values for blood glucose, serum insulin and serum C-peptide after miglitol were not different from those found after placebo. The post-peak AUC-ratio (AUC (peak, 180 min) on miglitol/AUC (peak, 180 min) on placebo) was for glucose 1.15 (CI 0.94–1.40, P=0.16), for insulin 1.12 (CI 0.95–1.33, P=0.17) and for C-peptide 0.98 (CI 0.81–1.18, P=0.82). It is concluded that miglitol exerts no clinically relevant extraintestinal effects on glucose control.
