Diabetes Oral Drugs – Alpha Glucosidase Inhibitors

Diabetes medications fall in two broad classes. Oral Pills and Injectables. Oral pills fall in different classes of drugs depending upon the mode of action and will be covering details about Alpha Glucosidase Inhibitors anti-hyperglycemic drugs here.


The first alpha glucosidase inhibitor to get FDA approval in USA was Acarbose in 1995. Miglitol followed in 1999. Voglibose is the latest addition.

Mode Of Action:

Alpha glucosidase inhibitors slow down the digestion and absorption of carbohydrates by blocking the enzyme alpha glucosidase, which helps in digesting carbohydrates in the small intestine. This slowing down of absorption causes the bloodsugar level to peak less after  a carbohydrate rich meal and therefore aids in a better bloodsugar control.
