Monitoring Parameters

Drug Interactions
Concomitant use w/ insulin increases the risk of hypoglycaemia. Intestinal adsorbents (e.g. charcoal) and carbohydrate-splitting digestive enzyme supplements (e.g. amylase, pancreatin) may reduce glycaemic effects. May significantly reduce the bioavailability of ranitidine and propranolol.
Mechanism of Action: Miglitol reversibly inhibits membrane-bound intestinal α-glucosidase enzymes which hydrolyse oligosaccharides and disaccharides to glucose and other monosaccharides in the small intestinal brush border. It delays carbohydrate breakdown, glucose absorption and reduces postprandial hyperglycaemia.
Absorption: Absorption from GI tract is saturable at high doses. Bioavailability: 50-70% (100 mg); 100% (25 mg). Time to peak plasma concentration: W/in 2-3 hr.
Distribution: It crosses the placenta and enters breast milk (small amounts). Volume of distribution: 0.18 L/kg. Plasma protein binding: <4%.
Metabolism: Not metabolised.
Excretion: Via urine (95%) as unchanged drug. Elimination half-life: Approx 2 hr.
