Glipizide is an oral sulfonylurea medication used to manage type 2 diabetes mellitus. It works by stimulating pancreatic beta cells to release insulin, helping lower blood glucose levels, particularly after meals. Glipizide is typically used alongside dietary modifications and exercise and may be combined with other antidiabetic agents when additional glycemic control is needed. It should be taken 30 minutes before meals, as taking it with food can delay absorption and increase the risk of delayed hypoglycemia. Patients with G6PD deficiency are at increased risk of hemolytic anemia and should be evaluated before starting therapy.
