Exenatide Extended-Release: An Updated Review of Its Use in Type 2 Diabetes Mellitus

Drugs. 2015 Jul;75(10):1141-52. doi: 10.1007/s40265-015-0420-z.


Exenatide extended-release (exenatide ER) [Bydureon(®)] is a glucagon-like peptide-1 receptor agonist, approved for the treatment of type 2 diabetes mellitus. It is injected subcutaneously by patients once weekly, with no dose titration required. This article updates an earlier review of exenatide ER in the management of type 2 diabetes, focusing on recently published data. In randomized, controlled trials, adjunctive exenatide ER 2 mg once weekly for 24-30 weeks significantly improved glycaemic control and reduced bodyweight in patients with inadequately controlled type 2 diabetes despite diet plus exercise and/or oral antihyperglycaemic drugs (OADs). These beneficial effects of exenatide ER were maintained after up to 6 years of treatment. In patients receiving one or more OADs, addition of exenatide ER provided better glycaemic control than an immediate-release formulation of exenatide (exenatide twice daily), sitagliptin, pioglitazone, insulin glargine or insulin detemir, and was slightly less effective than liraglutide. In patients treated with diet plus exercise alone, adjunctive exenatide ER was noninferior to metformin and superior to sitagliptin, but was not noninferior to pioglitazone. Exenatide ER was generally well tolerated, with a low inherent risk of hypoglycaemia. The most common adverse events were mild to moderate gastrointestinal events, injection-site reactions and headache. Thus, exenatide ER is a useful treatment option in the management of type 2 diabetes. It offers a convenient, once-weekly regimen and can be administered by patients via a pen injection system or syringes and needles.
