Glibenclamide, also known as glyburide, is a medication used to treat diabetes mellitus type 2.[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 diabetes mellitus type 1.[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.[2] 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.[3][1] It is available as a generic medication.[2] In 2018, it was the 203rd most commonly prescribed medication in the United States, with more than 2 million prescriptions.[4][5]
Medical uses[]
It is used in the treatment of type 2 diabetes.
It is not as good as either metformin or insulin in those who have gestational diabetes.[6]
Side effects[]
Frequently reported side effects include: nausea, heartburn, weight gain, and bloating.[7] The medication is also a major cause of medication-induced hypoglycemia. The risk is greater than with other sulfonylureas.[8] Cholestatic jaundice is noted.
Glibenclamide may be not recommended in those with G6PD deficiency, as it may cause acute hemolysis.[9]
Pregnancy and breastfeeding[]
It is generally not recommended during pregnancy but can be used during breastfeeding.[2]
Mechanism of action[]
The medication works by binding to and inhibiting the ATP-sensitive potassium channels (KATP) inhibitory regulatory subunit sulfonylurea receptor 1 (SUR1)[10] in pancreatic beta cells. This inhibition causes cell membrane depolarization, opening voltage-dependent calcium channels. This results in an increase in intracellular calcium in the pancreatic beta cell and subsequent stimulation of insulin release.
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.[11] Moreover, under ischemic conditions SUR1, the regulatory subunit of the KATP- and the NCCa-ATP-channels, is expressed in neurons, astrocytes, oligodendrocytes, endothelial cells[12] and by reactive microglia.[11]
As per the research papers, this sulphonyl urea 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.[13][14] Tolbutamine also has a similar effect.
History[]
It was developed in 1966 in a cooperative study between Boehringer Mannheim (now part of Roche) and Hoechst (now part of Sanofi-Aventis).[15]
Trade names[]
Glibenclamide is available as a generic, is manufactured by many pharmaceutical companies and is sold in doses of 1.25, 2.5 and 5 mg under many brand names including Gliben-J, Daonil, Diabeta, Euglucon, Gilemal, Glidanil, Glybovin, Glynase, Maninil, Micronase and Semi-Daonil. It is also available in a fixed-dose combination drug with metformin that is sold under various trade names, e.g. Bagomet Plus, Benimet, Glibomet, Gluconorm, Glucored, Glucovance, Metglib and many others.[citation needed]
