Mechanism of action

Sourced from openFDA

In contrast to sulfonylureas, miglitol tablets do not enhance insulin secretion. The antihyperglycemic action of miglitol results from a reversible inhibition of membrane-bound intestinal α-glucoside hydrolase enzymes.

alpha Glucosidase

Indications

Sourced from openFDA
  • Miglitol tablets are indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus.ICD-10: E11.9

Contraindications

Sourced from openFDA
  • Miglitol tablets are contraindicated in patients with: Diabetic ketoacidosis Inflammatory bowel disease, colonic ulceration, or partial intestinal obstruction, and in patients predisposed to intestinal obstruction Chronic intestinal diseases associated with marked disorders of digestion or absorption, or with conditions that may deteriorate as a result of increased gas formation in the intestine Hypersensitivity to the drug or any of its componentscontraindicated

Dosage & administration

Sourced from openFDA

There is no fixed dosage regimen for the management of diabetes mellitus with miglitol tablets or any other pharmacologic agent. Dosage of miglitol tablets must be individualized on the basis of both effectiveness and tolerance while not exceeding the maximum recommended dosage of 100 mg 3 times daily. Miglitol tablets should be taken three times daily at the start of each main meal. Miglitol tablets should be started at 25 mg, and the dosage gradually increased both to reduce gastrointestinal adverse effects and to permit identification of the minimum dose required for adequate glycemic control of the patient. During treatment initiation and dose titration, one-hour postprandial plasma glucose may be used to determine the therapeutic response to miglitol tablets and identify the minimum effective dose for the patient. Thereafter, glycosylated hemoglobin should be measured at intervals of approximately 3 months. The therapeutic goal should be to decrease both postprandial plasma glucose and glycosylated hemoglobin levels to normal or near normal by using the lowest effective dose of miglitol tablets, either as monotherapy or in combination with a sulfonylurea. Initial Dosage The recommended starting dosage of miglitol tablets is 25 mg, given orally three times daily at the start of each main meal. However, some patients may benefit by starting at 25 mg once daily to minimize gastrointestinal adverse effects, and gradually increasing the frequency of administration to 3 times daily.

Adverse reactions

Sourced from openFDA

Gastrointestinal Gastrointestinal symptoms are the most common reactions to miglitol tablets. In U.S. placebo-controlled trials, the incidences of abdominal pain, diarrhea, and flatulence were 11.7%, 28.7%, and 41.5% respectively in 962 patients treated with miglitol tablets, 25 mg to 100 mg 3 times daily, whereas the corresponding incidences were 4.7%, 10.0%, and 12.0% in 603 placebo-treated patients. The incidence of diarrhea and abdominal pain tended to diminish with continued treatment. Dermatologic Skin rash was reported in 4.3% of patients treated with miglitol tablets compared to 2.4% of placebo-treated patients. Rashes were generally transient and most were assessed as unrelated to miglitol tablets by physician investigators. Abnormal Laboratory Findings Low serum iron occurred more often in patients treated with miglitol tablets (9.2%) than in placebo-treated patients (4.2%) but did not persist in the majority of cases and was not associated with reductions in hemoglobin or changes in other hematologic indices. Postmarketing Experience The following adverse reactions have been reported during post-approval use of miglitol tablets. Because these reactions are reported voluntarily from a population of uncertain size, it is generally not possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Gastrointestinal Disorders: ileus (including paralytic ileus), subileus, gastrointestinal pain, nausea, abdominal distention.

Use in specific populations

Sourced from openFDA

Pregnancy Teratogenic Effects Pregnancy Category B The safety of miglitol tablets in pregnant women has not been established. Developmental toxicology studies have been performed in rats at doses of 50, 150 and 450 mg/kg, corresponding to levels of approximately 1.5, 4, and 12 times the maximum recommended human exposure based on body surface area. In rabbits, doses of 10, 45, and 200 mg/kg corresponding to levels of approximately 0.5, 3, and 10 times the human exposure were examined. These studies revealed no evidence of fetal malformations attributable to miglitol. Doses of miglitol up to 4 and 3 times the human dose (based on body surface area), for rats and rabbits respectively, did not reveal evidence of impaired fertility or harm to the fetus. The highest doses tested in these studies, 450 mg/kg in the rat and 200 mg/kg in the rabbit promoted maternal and/or fetal toxicity. Fetotoxicity was indicated by a slight but significant reduction in fetal weight in the rat study and slight reduction in fetal weight, delayed ossification of the fetal skeleton and increase in the percentage of non-viable fetuses in the rabbit study. In the peri-postnatal study in rats, the NOAEL (No Observed Adverse Effect Level) was 100 mg/kg (corresponding to approximately four times the exposure to humans, based on body surface area).

Pharmacokinetics

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

Overdosage

Sourced from openFDA

Unlike sulfonylureas or insulin, an overdose of miglitol tablets will not result in hypoglycemia. An overdose may result in transient increases in flatulence, diarrhea, and abdominal discomfort. Because of the lack of extra-intestinal effects seen with miglitol tablets, no serious systemic reactions are expected in the event of an overdose.
