{{/items}} {{^items}}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)
Mechanism of Action
Acarbose reversibly bind to pancreatic alpha-amylase and membrane-bound intestinal alpha-glucoside hydrolases. These enzymes inhibit hydrolysis of complex starches to oligosaccharides in the lumen of the small intestine and hydrolysis of oligosaccharides, trisaccharides, and disaccharides to glucose and other monosaccharides in the brush border of the small intestine.
Pharmacokinetics
- Absorption
- Extremely low bioavailability. Less than 2% of an oral dose of acarbose was absorbed as active drug. Peak plasma concentrations of the active drug were achieved 1 hour after dosing. Drug accumulation does not occur with multiple doses.
- Distribution
- Metabolism
- Acarbose is only metabolized within the gastrointestinal tract by intestinal bacteria and also digestive enzymes to a lesser extent. 4-methylpyrogallol derivatives (sulfate, methyl, and glucuronide conjugates) are the major metabolites. One metabolite (formed by cleavage of a glucose molecule from acarbose) also has alpha-glucosidase inhibitory activity.
- Elimination
Toxicity
Gastrointestinal symptoms are the most common reactions to acarbose.
