Glimepiride

Mechanism of action:
Glimepiride is a third-generation sulfonylurea derivative. Glimepiride binds to and inhibits sulfonylurea receptor 1 (SUR1) on the membrane of pancreatic β cells. This receptor is the regulatory subunit of the ATP-sensitive potassium channel. Once inhibited by glimepiride, potassium efflux decreases and the cell membrane undergoes depolarization. This depolarization opens calcium channels, increases calcium influx, and stimulates insulin release.
