Glibenclamide

Glibenclamide is an oral sulfonylurea medication that lowers blood glucose by stimulating insulin release from pancreatic beta cells. It is also known as glyburide.

Sulfonylurea receptor 1: A regulatory subunit of ATP-sensitive potassium channels in pancreatic beta cells that binds sulfonylurea drugs. Glibenclamide binds this receptor to close beta-cell potassium channels.
Type 2 diabetes: A chronic metabolic disease characterized by insulin resistance and progressive impairment of insulin production. Glibenclamide is used to improve glycemic control in this form of diabetes.
Gliclazide: A sulfonylurea medication that stimulates insulin release to treat type 2 diabetes. It is a related alternative with different pharmacokinetic and hypoglycemia considerations.
Sulfonylurea-induced hypoglycemia: Low blood glucose caused by insulin secretion stimulated by a sulfonylurea medication. Glibenclamide is associated with prolonged episodes, especially in older adults and renal impairment.
Sulfonylurea: A class of medicines that lowers blood glucose by stimulating insulin release from pancreatic beta cells. Glibenclamide is a member of this insulin-secretagogue drug class.
ATP-sensitive potassium channel: A potassium channel whose opening responds to cellular energy levels and helps regulate cell electrical activity. Glibenclamide closes these channels, initiating insulin secretion.
Glycemic control: The management of blood glucose within a target range to reduce symptoms and complications. Glibenclamide is prescribed to improve this outcome when diet and activity are insufficient.
Glimepiride: A long-acting sulfonylurea used to lower blood glucose in type 2 diabetes. It offers another insulin-stimulating option with a different dosing and safety profile.
Renal impairment: Reduced kidney function that alters the elimination of some medicines and their metabolites. Impaired clearance can increase glibenclamide-associated hypoglycemia risk.
Pancreatic islets: Clusters of hormone-producing cells in the pancreas that regulate blood glucose. Their beta cells produce the insulin whose release glibenclamide stimulates.
