Miglitol is a desoxynojirimycin derivative and inhibitor of alpha-glucosidase with antihyperglycemic activity. Miglitol binds to and inhibits alpha-glucosidase, an enteric enzyme found in the brush border of the small intestines that hydrolyzes oligosaccharides and disaccharides into glucose and other monosaccharides. This prevents the breakdown of larger carbohydrates into glucose and decreases the rise in postprandial blood glucose levels. Compared to acarbose, miglitol is systemically absorbed.
Miglitol is an alpha-Glucosidase Inhibitor. The mechanism of action of miglitol is as an alpha Glucosidase Inhibitor.

4.3 Drug Warning

Miglitol is contraindicated in patients with known hypersensitivity to the drug or diabetic ketoacidosis. The drug is also contraindicated in patients with inflammatory bowel disease, colonic ulceration, partial intestinal obstruction or predisposition to this condition, chronic intestinal diseases associated with marked disorders of digestion or absorption, and coexisting conditions that may deteriorate as a result of increased intestinal gas formation.

American Society of Health-System Pharmacists 2011; Drug Information 2011. Bethesda, MD. 2011


Miglitol should not cause hypoglycemia when administered alone in the fasting or postprandial state. There is an increased risk of hypoglycemia when miglitol is used concomitantly with insulinor a sulfonylurea antidiabetic agent. If hypoglycemia occurs, dosage of these agents should be adjusted appropriately.

American Society of Health-System Pharmacists 2011; Drug Information 2011. Bethesda, MD. 2011


Oral glucose (dextrose) should be used for the treatment of mild to moderate hypoglycemia instead of sucrose (table sugar, a disaccharide); absorption of oral glucose (a monosaccharide) is not delayed by miglitol. Severe hypoglycemia may require the use of either iv glucose infusion or parenteral glucagon.

American Society of Health-System Pharmacists 2011; Drug Information 2011. Bethesda, MD. 2011


There is a risk of possible loss of glycemic control in patients receiving miglitol during periods of stress (e.g., fever, trauma, infection, surgery); temporary administration of insulin may be required.

4.4 Drug Indication

For use as an adjunct to diet to improve glycemic control in patients with non-insulin-dependent diabetes mellitus (NIDDM) whose hyperglycemia cannot be managed with diet alone.


5 Pharmacology and Biochemistry
5.1 Pharmacology

Miglitol, an oral alpha-glucosidase inhibitor, is a desoxynojirimycin derivative that delays the digestion of ingested carbohydrates, thereby resulting in a smaller rise in blood glucose concentration following meals. As a consequence of plasma glucose reduction, miglitol reduce levels of glycosylated hemoglobin in patients with Type II (non-insulin-dependent) diabetes mellitus. Systemic nonenzymatic protein glycosylation, as reflected by levels of glycosylated hemoglobin, is a function of average blood glucose concentration over time. Because its mechanism of action is different, the effect of miglitol to enhance glycemic control is additive to that of sulfonylureas when used in combination. In addition, miglitol diminishes the insulinotropic and weight-increasing effects of sulfonylureas. Miglitol has minor inhibitory activity against lactase and consequently, at the recommended doses, would not be expected to induce lactose intolerance.

5.5 Absorption, Distribution and Excretion

Absorption

Absorption of miglitol is saturable at high doses with 25 mg being completely absorbed while a 100-mg dose is only 50-70% absorbed. No evidence exists to show that systemic absorption of miglitol adds to its therapeutic effect.


Route of Elimination

Miglitol is not metabolized in man or in any animal species studied. It is eliminated by renal excretion as an unchanged drug.


Volume of Distribution

0.18 L/kg


Absorption of miglitol is saturable at high doses: a dose of 25 mg is completely absorbed, whereas a dose of 100 mg is only 50% - 70% absorbed. For all doses, peak concentrations are reached in 2-3 hours.

5.8 Mechanism of Action

In contrast to sulfonylureas, miglitol does not enhance insulin secretion. The antihyperglycemic action of miglitol results from a reversible inhibition of membrane-bound intestinal a-glucoside hydrolase enzymes. Membrane-bound intestinal a-glucosidases hydrolyze oligosaccharides and disaccharides to glucose and other monosaccharides in the brush border of the small intestine. In diabetic patients, this enzyme inhibition results in delayed glucose absorption and lowering of postprandial hyperglycemia.


Miglitol is a desoxynojirimycin derivative that delays the digestion of ingested carbohydrates, thereby resulting in a smaller rise in blood glucose concentration following meals. As a consequence of plasma glucose reduction, miglitol tablets reduce levels of glycosylated hemoglobin in patients with Type II (non-insulin-dependent) diabetes mellitus. Systemic nonenzymatic protein glycosylation, as reflected by levels of glycosylated hemoglobin, is a function of average blood glucose concentration over time.

Miglitol inhibits alpha-glucosidase enzymes (e.g., sucrase, glucoamylase, maltase, isomaltase) that hydrolyze oligosaccharides, trisaccharides, and disaccharides to glucose and other monosaccharides in the small intestinal brush border. The drug has little or no inhibitory effect on trehalase, lactase, or pancreatic alpha-amylase; it is not expected to produce lactose intolerance. Miglitol delays carbohydrate breakdown and glucose absorption and reduces postprandial hyperglycemia in diabetic patients; fasting blood glucose concentrations are mildly decreased.

American Society of Health-System Pharmacists 2011; Drug Information 2011. Bethesda, MD. 2011


In contrast to sulfonylurea antidiabetic agents, miglitol does not enhance insulin secretion. The drug does not produce hypoglycemia when given as monotherapy in the fasted or postprandial state. When used in combination with sulfonylurea antidiabetic agents, miglitol reduces the insulinotropic and weight-increasing effects of sulfonylureas. Miglitol does not produce clinically important weight loss.

American Society of Health-System Pharmacists 2011; Drug Information 2011. Bethesda, MD. 2011


Oral administration of miglitol has been reported to produce glucagon-like peptide 1 (GLP-1). /The authors/ hypothesized that p.o. administration of miglitol, an absorbable antidiabetic drug, reduces myocardial infarct size by stimulating GLP-1 receptors and inhibiting glycogenolysis in the myocardium. The effects of p.o. and i.v. administration of miglitol on myocardial infarct size were compared in a rabbit model of ischemia induced by 30 min of coronary occlusion and 48 hr of reperfusion. The levels of phospho(p)-PI3kinase and p-Akt were measured in cardiac tissue by use of Western blot analysis. Both p.o. and i.v. administration of miglitol reduced the infarct size, and this effect was greater after p.o. than after i.v. administration under similar plasma miglitol concentrations. The reduction in infarct size induced by p.o. miglitol but not that induced by i.v. miglitol was partially inhibited by treatment with exendin(9-39), a GLP-1 receptor blocker. Both p.o. and i.v. miglitol improved ejection fraction and +/-dP/dt after myocardial infarction. Miglitol administered p.o. but not i.v. up-regulated the myocardial expression of phospho(p)-PI3kinase and p-Akt following myocardial infarction; an effect that was inhibited by exendin(9-39). Administration of miglitol p.o. reduces myocardial infarct size through stimulation of GLP-1 receptors and activation of PI3kinase-Akt pathway in addition to the inhibition of glycogenolysis. These findings may have clinical implications for the p.o. administration of miglitol for the treatment of patients with diabetes mellitus combined with coronary artery disease.

Imino sugars are used to treat type 2 diabetes mellitus (miglitol (Glyset)) and lysosomal storage disorders (miglustat (Zavesca)) based on the inhibition of alpha-glucosidases and glucosyltransferases. In this substrate specificity study, /investigators/ examined the interactions of imino sugars with a novel human glucose sensor, sodium/glucose cotransporter type 3 (hSGLT3), using expression in Xenopus laevis oocytes and electrophysiology. The results for hSGLT3 are compared with those for alpha-glucosidases and human SGLT type 1 (hSGLT1), a well characterized sodium/glucose cotransporter of the SGLT family. In general, substrates have lower apparent affinities (K0.5) for hSGLT3 than hSGLT1 (D-glucose, alpha-methyl-D-glucose, 1-deoxy-D-glucose, and 4-deoxy-4-fluoro-D-glucose exhibit K0.5 values of 19, 21, 43, and 17 mM, respectively, for hSGLT3, and 0.5, 0.7, 10, and 0.07 mM, respectively, for hSGLT1). However, specificity of hSGLT3 binding is greater (D-galactose and 4-deoxy-4-fluoro-D-galactose are not hSGLT3 substrates, but have hSGLT1 K0.5 values of 0.6 and 1.3 mM). An important deviation from this trend is potent hSGLT3 activation by the imino sugars 1-deoxynojirimycin (DNJ), N-hydroxylethyl-1-deoxynojirimycin (miglitol), N-butyl-1-deoxynojirimycin (miglustat), N-ethyl-1-deoxynojirimycin, and 1-deoxynojirimycin-1-sulfonic acid, with K0.5 values of 0.5 to 9 microM. The diastereomer 1-deoxygalactonojirimycin activates hSGT3 with a K0.5 value of 11 mM, a 3000-fold less potent interaction than is observed for DNJ (4 microM). These imino sugar binding characteristics are similar to those for alpha-glucosidases, but there are no interactions with hSGLT1. This work provides insights into hSGLT3 and -1 substrate binding interactions, establishes a pharmacological profile to study endogenous hSGLT3, and may have important ramifications for the clinical application of imino sugars.
