DescriptionGliquidone is an anti-diabetic drug in the sulfonylurea class. It is used in the treatment of diabetes mellitus type 2. It is an ATP-dependent K+ (KATP) channel blocker. This block causes a depolarization which leads to activation of voltage-dependent Ca channels and Ca2+ influx, and eventually increases insulin release.

General function:
Involved in inward rectifier potassium channel activity
Specific function:
This potassium channel is controlled by G proteins. Inward rectifier potassium channels are characterized by a greater tendency to allow potassium to flow into the cell rather than out of it. Their voltage dependence is regulated by the concentration of extracellular potassium; as external potassium is raised, the voltage range of the channel opening shifts to more positive voltages. The inward rectification is mainly due to the blockage of outward current by internal magnesium. Can be blocked by external barium
