About this product
Miglitol
Miglitol (CAS No. 72432-03-2) is an oral alpha-glucosidase inhibitor used to manage type 2 diabetes mellitus by reducing postprandial blood glucose spikes. With a molecular formula of C₈H₁₇NO₅ and a purity of 98%, it appears as an off-white to light yellow crystalline powder.
Chemical and Physical Properties
CAS Number : 72432-03-2
Molecular Formula : C₈H₁₇NO₅
Molecular Weight : 207.22 g/mol
Melting Point : 144.0–148.0°C
Boiling Point : 453.7°C at 760 mmHg
Density : 1.458 g/cm³
Optical Rotation : -7.0° to -9.0° (c=5 in H₂O)
Refractivity : 1.598
Mechanism of Action
Miglitol inhibits intestinal alpha-glucosidase enzymes, which are responsible for breaking down complex carbohydrates into absorbable monosaccharides like glucose. By delaying carbohydrate digestion, it reduces post-meal blood glucose levels and improves glycemic control .
Applications
Type 2 Diabetes Management : Used alongside diet and exercise to regulate blood sugar, particularly in patients unresponsive to dietary adjustments alone.
Combination Therapy : Often prescribed with sulfonylureas or insulin for enhanced glycemic control.
Dosage and Administration
Standard Dose : 25–100 mg taken orally three times daily, immediately before meals.
Forms : Available as 25 mg, 50 mg, and 100 mg tablets.
Storage
Store at 2–8°C for long-term stability.
Safety and Side Effects
Common Adverse Effects : Flatulence, abdominal pain, and diarrhea (typically mild and transient).
Hypoglycemia Risk : Low when used as monotherapy but possible when combined with other antidiabetic agents.
Contraindications : Severe renal impairment or inflammatory bowel disease.
Pharmacokinetics
Absorption/Excretion : Minimally absorbed systemically; excreted unchanged via the kidneys.
Special Populations : No dosage adjustments needed for elderly patients or those with mild-to-moderate renal/hepatic impairment.
In summary, Miglitol is a first-line or adjunct therapy for type 2 diabetes, offering targeted postprandial glucose control with a well-tolerated safety profile. Its molecular formula (C₈H₁₇NO₅) and pseudomonosaccharide structure make it distinct from other antidiabetic agents.
