- Sulfonylurea
- A class of oral hypoglycemic agents (pills and capsules taken to lower the level of blood glucose) by people with type 2 diabetes. The sulfonylureas increase the secretion of insulin by the pancreas. There are two generations of sulfonylureas. The main difference between the first- and second-generation sulfonylureas is in the way they are eliminated from the body. As a consequence, second-generation sulfonylureas are usually taken less frequently each day than first-generation sulfonylureas and generally are preferred when there is poor function of the kidneys. The first-generation sulfonylureas are Dymelor (acetohexamide), Diabinese (chlorpropamide), Tolinase (tolazamide), and Orinase (tolbutamide). The second-generation sulfonylureas include Glucotrol and Glucotrol XL (glipizide), DiaBeta, Micronase, and Glynase PresTab (glyburide)and Amaryl (glimepiride).
