⚡ Quick Answer — What is Mignar?
Mignar is a brand of miglitol (25 mg or 50 mg), an alpha-glucosidase inhibitor used for type 2 diabetes and prediabetes. It works in the gut: it slows the breakdown of complex carbohydrates into glucose, blunting the post-meal blood-sugar spike. It does not cause hypoglycaemia on its own. HbA1c reduction: 0.5–0.8 percentage points — modest but particularly useful for people with high post-meal glucose (and normal fasting glucose). Take the tablet with the very first bite of each main meal. Most completely absorbed of the alpha-glucosidase inhibitors — some systemic effect, not just local gut action. Main side effects are entirely GI: flatulence, bloating, diarrhoea (improves after 2–4 weeks on gradual up-titration). Avoid in inflammatory bowel disease, chronic intestinal disorders, severe renal impairment, and pregnancy.

What Is Mignar?
Mignar is an oral antidiabetic medicine containing miglitol (25 mg or 50 mg), manufactured by Glenmark Pharmaceuticals. Available in packs of 30, 60, 90 or 180 tablets. miglitol is an alpha-glucosidase inhibitor — a class that acts locally in the small intestine to slow carbohydrate digestion. First approved in 1996 (EU) / 1999 (US). Approved in US and EU but less widely used than acarbose.
Alpha-glucosidase inhibitors are a good fit for patients whose main problem is post-meal glucose spikes (especially on carbohydrate-heavy diets) while fasting glucose is close to normal — a pattern common in Asian populations.
How Does Mignar Work?
When you eat a carbohydrate meal, enzymes in the small intestine (alpha-amylase and alpha-glucosidases at the brush border) break complex carbohydrates into simple sugars (glucose) that can then be absorbed into the bloodstream.
miglitol competitively inhibits those enzymes. The effect is:
- Delayed carbohydrate digestion — glucose is released more gradually over the 2–3 hours after a meal
- Lower post-meal glucose peak (by 40–60 mg/dL on average)
- Reduced demand for post-meal insulin release — may preserve beta-cell function over time
- No direct effect on fasting glucose or insulin release — so no hypoglycaemia as monotherapy
Because the drug acts entirely within the gut lumen (systemic absorption is minimal for acarbose and voglibose), it has very few systemic side effects. Typical HbA1c reduction: 0.5–0.8 percentage points. Fasting glucose is essentially unchanged.
Dosage and Administration
Dose: 25 mg three times daily with the first bite of each main meal. Titrate to 50 mg three times daily after 4–8 weeks. Max 100 mg three times daily.
- Take with the first bite of the meal. Taking after the meal is much less effective — the enzymes are already acting.
- Start low, titrate slowly. The commonest reason for stopping is GI side effects. Starting at the lowest dose and titrating over 4–8 weeks dramatically improves tolerability.
- Skip the dose if you skip the meal.
- Hypoglycaemia rescue: if hypoglycaemia occurs on combination therapy (with sulfonylurea or insulin), use pure glucose (dextrose) — not sucrose, bread, or fruit juice. Alpha-glucosidase inhibitors block sucrose breakdown, so table sugar acts too slowly.
- Renal: avoid if eGFR < 25–30.
Side Effects
Almost all side effects are GI and due to unabsorbed carbohydrates fermenting in the colon:
Common (up to 30% in first weeks; improves to < 10% with slow titration):
- Flatulence
- Bloating, abdominal discomfort
- Soft stools or diarrhoea
- Borborygmi (audible gut rumbling)
Uncommon: transient liver-enzyme elevations (mostly with acarbose at high doses), rash, hypersensitivity.
Because miglitol does not stimulate insulin release, it does not cause hypoglycaemia on its own. Hypoglycaemia risk only appears when combined with a sulfonylurea, meglitinide, or insulin.
Drug Interactions
- Digestive enzyme preparations (pancreatin, amylase) — counteract the drug’s effect; do not combine.
- Sulfonylureas, meglitinides, insulin — additive glucose-lowering with hypoglycaemia risk. Use glucose (dextrose), not cane sugar, to treat a hypo.
- Thiazide diuretics, corticosteroids, thyroid hormones — may reduce glucose-lowering effect.
- Digoxin — acarbose may reduce digoxin absorption; separate by 2 hours.
- Neomycin, antibiotics affecting gut flora — may worsen GI side effects.
Who Should Not Take Mignar?
- Inflammatory bowel disease (Crohn’s, ulcerative colitis)
- Chronic intestinal disorders, partial intestinal obstruction
- Malabsorption syndromes
- Large hiatus hernias or conditions worsened by increased gas formation
- Severe renal impairment (eGFR < 25–30)
- Severe hepatic impairment
- Pregnancy and breastfeeding
- Children (safety not established)
- Diabetic ketoacidosis
- Known hypersensitivity
Storage
Store Mignar below 25°C in a dry place, in the original blister. Keep out of reach of children.
Frequently Asked Questions
Is miglitol different from acarbose?
Miglitol is structurally similar but better absorbed, so some activity is systemic as well as luminal. Clinical effect on HbA1c is similar to acarbose; GI side-effect burden is slightly lower. Miglitol does not interfere with starch digestion quite as much as acarbose, so it is sometimes better tolerated in Western diets.
Why do I have so much gas on Mignar?
Because unabsorbed carbohydrates travel to the colon, where gut bacteria ferment them into gases (hydrogen, methane, CO2). This is expected and usually improves within 2–4 weeks if you titrate slowly. Eating fewer concentrated sweets and sugars during the adjustment period also helps.
Can Mignar help me lose weight?
Modestly, if at all — alpha-glucosidase inhibitors are weight-neutral or result in mild weight loss (0.5–1.5 kg). SGLT-2 inhibitors and GLP-1 agonists are much stronger weight-loss agents.
Does Mignar cause hypoglycaemia?
Not on its own. When combined with a sulfonylurea or insulin, the combination can cause hypoglycaemia — and then it is important to use glucose tablets or dextrose, not table sugar, because miglitol blocks sucrose digestion.
Can Mignar be used for prediabetes?
Acarbose has good evidence in prediabetes (the STOP-NIDDM trial showed a 36% reduction in progression to type 2 diabetes), and it is used off-label for this indication in some regions. Metformin is the usual first choice.
