Description: Acarbose is an anti-diabetic drug used to treat diabetes mellitus type 2 and prediabetes. It is an inhibitor of alpha glucosidase, an intestinal enzyme that releases glucose from larger carbohydrates, and an inhibitor of pancreatic alpha-amylase, which hydrolyzes complex starches to oligosaccharides in the lumen of the small intestine. By this inhibition, acarbose reduces the rate of digestion of complex carbohydrates and acts as a starch blocker. It allows less glucose to be absorbed, decreasing blood glucose levels and reducing HbA1c level.
