Glibenclamide, also known as glyburide, is an antidiabetic medication used to treat type 2 diabetes.[1] It is recommended that it be taken together with diet and exercise.[1] It may be used with other antidiabetic medication.[1] It is not recommended for use by itself in type 1 diabetes.[1] It is taken by mouth.[1]

Common side effects include nausea and heartburn.[1] Serious side effects may include angioedema and low blood sugar.[1] It is generally not recommended during pregnancy but can be used during breastfeeding.[3] It is in the sulfonylureas class of medications and works by increasing the release of insulin from the pancreas.[1]

Glibenclamide was discovered in 1969 and approved for medical use in the United States in 1984.[4][1] It is available as a generic medication.[3] In 2021, it was the 214th most commonly prescribed medication in the United States, with more than 2 million prescriptions.[5][6]

Medical uses

Glibenclamide is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes.[2]

It is not as good as either metformin or insulin in those who have gestational diabetes.[7]

Side effects

Frequently reported side effects include: nausea, heartburn, weight gain, and bloating.[8] The medication is also a major cause of medication-induced hypoglycemia. The risk is greater than with other sulfonylureas.[9]


Glibenclamide may be not recommended in those with G6PD deficiency, as it may cause acute hemolysis.[10]

Pregnancy and breastfeeding

It is generally not recommended during pregnancy but can be used during breastfeeding.[3]

Mechanism of action

The medication, a sulfonylurea, works by binding to and inhibiting the ATP-sensitive potassium channels (KATP) inhibitory regulatory subunit sulfonylurea receptor 1 (SUR1)[11] in pancreatic beta cells. This inhibition causes cell membrane depolarization, opening voltage-dependent calcium Channels.[12]

This results in an increase in intracellular calcium in the pancreatic beta cell and subsequent stimulation of insulin release.[13]

After a cerebral ischemic insult, the blood–brain barrier is broken and glibenclamide can reach the central nervous system. Glibenclamide has been shown to bind more efficiently to the ischemic hemisphere.[14] Moreover, under ischemic conditions SUR1, the regulatory subunit of the KATP- and the NCCa-ATP-channels, is expressed in neurons, astrocytes, oligodendrocytes, endothelial cells[15] and by reactive microglia.[14]

As per the research papers, this sulphonylurea drugs also has extra hepatic effects. It works by inhibiting the enzyme Carnityl Acyl Transferase I (CAT-I) indirectly which is present in the mitochondria. This prevents the transport of long chain fatty acids into the mitochondria for beta-oxidation. This prevents hyperglycemia for which it is prescribed.[16][17]


It was developed in 1966 in a cooperative study between Boehringer Mannheim (now part of Roche) and Hoechst (now part of Sanofi-Aventis).[18]
