Glipizide is an ATP dependent K+ channels blocker in pancreatic B cells and brain GABA containing neurons resulting in insulin release.
Glipizide is an oral rapid- and short-acting anti-diabetic medication from the sulfonylurea class. It is classified as a second-generation sulfonylurea, which means that it undergoes enterohepatic circulation. Second-generation sulfonylureas are both more potent and have shorter half-lives than the first-generation sulfonylureas.
