详细说明

DrugBank - DB00284

• Drug Groups: approved; investigational
• Description: 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)
• Indication: For treatment and management of diabetes type II (used in combination therapy as a second or third line agent)
• Pharmacology: Used to reduce blood gluose in patients with type 2 diabetes. Acarbose is a complex oligosaccharide that delays the digestion of ingested carbohydrates, thereby resulting in a smaller rise in blood glucose concentration following meals. Acarbose binds to and inhibits alpha amylase and alpha-gluocside hydrolases. In diabetic patients, this enzyme inhibition results in a delayed glucose absorption and a lowering of postprandial hyperglycemia.
• Affected Organisms: Humans and other mammals
• Absorption: Extremely low bioavailability.
• Half Life: 2 hours
• Elimination: The fraction of acarbose that is absorbed as intact drug is almost completely excreted by the kidneys.
