Abstract:
Two glucagon-like peptide-1 (GLP-1) receptor agonists are currently approved for use in patients with type 2 diabetes mellitus: exenatide and liraglutide. Both of these injectable agents improve glycemic control as monotherapy or as combination therapy with oral agents. Overall, GLP-1 receptor agonists provide additive effects in dual and triple therapy regimens. In a clinical trial, the use of liraglutide resulted in greater improvements in glycosylated hemoglobin and fasting plasma glucose levels compared to exenatide, although the effects of exenatide on postprandial plasma glucose levels were greater. Clinical trials have also demonstrated statistically significant weight reduction, small beneficial effects on blood pressure, and unchanged lipid profiles with GLP-1 receptor agonists. The author reviews clinical trial data on the use of GLP-1 receptor agonists for patients with type 2 diabetes mellitus, outlines potential contraindications of these agents, and discusses the role of GLP-1 receptor agonists in algorithms for the initiation and advancement of treatment.

GLP-1, when administered in high doses intravenously, triggers insulin secretion, inhibits glucagon release, slows gastric emptying, reduces food intake, and restores normal insulin secretion. However, its rapid inactivation by the...
