G6PD is an enzyme that mediates the production of NADPH (nicotinamide adenine dinucleotide phosphate hydrogen) and ribose-5-phosphate. Individuals with polymorphic G6PD variants and haplotypes have been associated with variable drug response, and those with G6PD deficiency may experience an increased risk of adverse effects.

Based on studies, glibenclamide may induce acute haemolysis in diabetic patients who are carriers of the A-Haplotype 202A/376G (rs1050828 and rs1050829) variants, and the Mediterranean 563T (rs5030868) variant. The A-Haplotype variant has 10-60% deficiency in G6PD enzyme activity while the Mediterranean variant has <10% severely deficient activity.

EMA- and FDA-approved drug labels for glibenclamide cited that glibenclamide administration should be used in caution in patients carrying a G6PD enzyme deficiency due to the risk of acute haemolytic anaemia. The use of non-sulfonylurea alternative treatment is strongly recommended.

Pharmacogenetic testing in G6PD deficient individuals prior to glibenclamide administration has not yet been addressed by currently available references.

Thông tin tư vấn bệnh nhân
This drug may cause hypoglycaemia and reduced alertness, if affected, do not drive or operate machinery.
Monitor urine glucose test, fasting blood glucose, HbA1c (at least twice yearly in patients with stable glycaemic control, and quarterly in patients who do not meet treatment goals or with treatment change); signs and symptoms of hypoglycaemia during treatment.
Quá liều
Symptoms: Hypoglycaemia. Management: Symptomatic and supportive treatment. Administer activated charcoal. For mild hypoglycaemia without loss of consciousness or neurological findings, may give oral glucose, or adjust dosage and meal patterns. For hypoglycaemic coma, administer 50% glucose solution via rapid IV inj, followed by continuous infusion of 10% glucose solution to maintain blood glucose levels above 100 mg/dL.
Tương tác
Enhanced hypoglycaemic effect with azapropazone, phenylbutazone, chloramphenicol, ciprofloxacin, co-trimoxazole, sulfonamides, tetracyclines, anticoagulants, disopyramide, TCAs, MAOIs, allopurinol, sulphinpyrazone, probenecid, ACE inhibitors, testosterone, anabolic steroids. Enhanced hypoglycaemic effect and mask the symptoms of hypoglycaemia with β-blockers. Reduced hypoglycaemic effect with rifampicin, barbiturates, diazoxide, chlorpromazine, loop and thiazide diuretics, oestrogens, progesterone, oral contraceptives, corticosteroids, thyroid hormones. Increased plasma concentrations with miconazole, fluconazole. Additive effect with clofibrate. May increase plasma levels of ciclosporin. May alter anticoagulant effects of warfarin. Reduced plasma concentration and exposure with colesevelam.
Potentially Fatal: Increased risk of hepatotoxicity with bosentan.
Food Interaction
Alcohol may enhance hypoglycaemic effect or cause rare disulfiram-like reactions.
Tác dụng
Description: Glibenclamide lowers blood glucose concentration by stimulating the secretion of insulin from the pancreatic β-cells. It also reduces glucose output from and the liver and increases insulin sensitivity at peripheral target sites.
Synonym: Glyburide
Onset: Increase in serum insulin levels: 15-60 minutes.
Duration: ≤24 hours.
Absorption: Readily absorbed from the gastrointestinal tract. Time to peak plasma concentration: 2-4 hours.
Distribution: Crosses placenta. Plasma protein binding: 99% (extensive), mainly to albumin.
Metabolism: Almost completely metabolised in the liver into weakly active metabolites.
Excretion: Via urine (50%) and faeces (50%), as metabolites. Elimination half-life: 10 hours (conventional tab); approx 4 hours (modified-release tab).
