^NY (what is this?)

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.

Originally available in 1984, it is marketed by Pfizer under the brand name Glucotrol in the USA, where Pfizer sells Glucotrol in doses of 5 and 10 milligrams and Glucotrol XL (an extended release form of glipizide) in doses of 2.5, 5, and 10 milligrams. Other companies also market glipizide, most commonly extended release tablets of 5 and 10 milligrams.

Glipizide acts by partially blocking potassium channels among beta cells of pancreatic islets of Langerhans. By blocking potassium channels, the cell depolarizes which results in the opening of voltage-gated calcium channels. The resulting calcium influx encourages insulin release from beta cells.
