Acarbose (C0050393) |
|
|---|---|
| Definition (MSH) | An inhibitor of alpha glucosidase that retards the digestion and absorption of carbohydrates in the small intestine and hence reduces the increase in blood-glucose concentrations after a carbohydrate load. It is given orally to non-insulin dependent diabetes mellitus patients where diet modification or oral hypoglycemic agents do not control their condition. (From Martindale The Extra Pharmacopoeia, 31st ed) |
| Definition (PDQ) | A complex oligosaccharide used as a hypoglycemic agent in diabetes management. Acarbose inhibits enzymes required in catabolism of carbohydrates, specifically pancreatic alpha-amylase, which hydrolyzes complex starches to oligosaccharides in the lumen of the small intestine, and the membrane-bound intestinal alpha-glucosidases, which hydrolyze oligosaccharides, trisaccharides, and disaccharides to glucose and other monosaccharides in the small intestine. When acarbose is orally administered, less digestion of complex carbohydrates occur and less glucose is absorbed in the small intestine, thereby producing a smaller rise in postprandial blood glucose levels after a carbohydrate load. Check for "http://www.cancer.gov/Search/ClinicalTrialsLink.aspx?id=42140&idtype=1" active clinical trials or "http://www.cancer.gov/Search/ClinicalTrialsLink.aspx?id=42140&idtype=1&closed=1" closed clinical trials using this agent.
