Sulfonylureas
Historically, increasing insulin output by the pancreas has been the major area targeted by medications used to treat type 2 diabetes. Medications that increase the output of insulin belong to a class of drugs called sulfonylureas. Sulfonylureas primarily lower blood glucose levels by increasing the release of insulin from the pancreas. Older generations of these drugs include chlorpropamide and tolbutamide, while newer drugs include glyburide (DiaBeta), glipizide (Glucotrol), and glimepiride (Amaryl). These drugs are effective in rapidly lowering blood sugar but run the risk of causing hypoglycemia (abnormally low and dangerous levels of blood sugar). In addition, they are sulfa-containing drugs and should be avoided by patients who are allergic to sulfa .
