Mechanism of action

Acarbose is an alpha-glucosidase inhibitor that competitively binds to enzymes in the brush border of the small intestine, delaying the breakdown of disaccharides and complex carbohydrates into monosaccharides. This delays glucose absorption and results in lower postprandial glucose levels in patients with type 2 diabetes. The drug does not stimulate insulin secretion and works through a local gastrointestinal mechanism.
