Effects of the disaccharidase inhibitor acarbose on meal and intravenous glucose tolerance in normal man.
To determine whether the effects of the disaccharidase inhibitor Acarbose on glucose tolerance could be solely explained via an action on intestinal nutrient absorption, the effects of this agent and placebo (100 mg p.o.) on intravenous and postprandial glucose tolerance were compared in six normal subjects. Acarbose significantly diminished plasma glucose, insulin, and gastrointestinal inhibitory polypeptide responses following meal ingestion without affecting plasma glucagon and pancreatic polypeptide responses, but had no effect on plasma glucose and insulin responses following intravenous injection of glucose. These results suggest that the acute effects of Acarbose on glucose tolerance can be explained on the basis of its ability to alter intestinal nutrient absorption.
