Pharmacological Category : Antidiabetic Drug (Alpha Glucosidase Inhibitor)
Mechanism of Action (MOA)
DIABAY (Acarbose) is a competitive inhibitor of intestinal alpha-glucosidases with maximum specific inhibitory activity against sucrose. DIABAY also blocks the activity of pancreatic alpha amylase. DIABAY dose-dependently delays the digestion of starch and sucrose into absorbable monosaccharides in the small intestine.
- Absorption : 35% is absorbed in the form of metabolites
- Metabolism : By intestinal enzyme and by the microbial flora
- Excretion : Urine and faeces

- Initial dose : One tablet of DIABAY 25 mg three times a day with the first bite of each main meal.
- Maximum dose :

Warnings / Precautions
- Use oral glucose (dextrose) instead of sucrose (cane sugar) in treatment of mild to moderate hypoglycaemia.
- Elevated serum transaminase levels, fulminant hepatitis, and hyperbilirubinemia reported. Reduce dose or discontinue if elevated serum transaminases persist.
- A temporary loss of control of blood glucose may occur when exposed to stress; temporary insulin therapy may be necessary.
- Pneumatosis cystoides intestinalis reported. Reduce dose temporarily or permanently if strongly distressing symptoms develop in spite of adherence to the diabetic diet.
- Acarbose may inhibit the absorption of digoxin.
- With other antidiabetics including insulin reduction in dose may be needed.
- Gastrointestinal adsorbents and digestive enzyme preparations can diminish the effects of acarbose and should be avoided.
- Neomycin and cholestyramine may enhance the effects of acarbose.
- Closely observe for loss of blood glucose control with thiazides and other diuretics, corticosteroids, phenothiazines, thyroid products, estrogens, oral contraceptives, phenytoin, nicotinic acid, sympathomimetics, calcium channel blockers, and isoniazid.
