Description
Glipizide is a second generation sulfonylurea that exhibits anti-diabetic activity. Glipizide inhibits ATP-dependent K+ channels in β cells, forcing cells to remain depolarized, increasing Ca2+ influx and insulin secretion. Glipizide also decreases the metabolic clearance rate of insulin.
