GENERIC NAME: exenatide


DRUG CLASS AND MECHANISM: Exenatide is an injectable drug that reduces the level of sugar (glucose) in the blood. It is used for treating type 2 diabetes. Exenatide belongs in a class of drugs called incretin mimetics because these drugs mimic the effects of incretins. Incretins, such as human-glucagon-like peptide-1 (GLP-1), are hormones that are produced and released into the blood by the intestine in response to food. GLP-1 increases the secretion of insulin from the pancreas, slows absorption of glucose from the gut, and reduces the action of glucagon. (Glucagon is a hormone that increases glucose production by the liver.) All three of these actions reduce levels of glucose in the blood. In addition, GLP-1 reduces appetite. Exenatide is a synthetic (man-made) hormone that resembles and acts like GLP-1. In studies, exenatide-treated patients achieved lower blood glucose levels and experienced weight loss. Exenatide was approved by the FDA in May 2005.



PREPARATIONS: Multiple dose pre-filled pen: 1.2 mL, 5 mcg per dose (60 doses) or 2.4 mL, 10 mcg per dose (60 doses)

STORAGE: Exenatide should be refrigerated between 2-8 C (36-46 F) and protected from light. After first use, it may be stored at room temperature and should not be frozen or used if frozen. The pen should be discarded 30 days after its first use.
