As knowledge of pathophysiologic mechanisms of diabetes mellitus has increased, clinical attention has shifted to the incretin system. Incretin hormones, including glucagon-like peptide-1, or GLP-1, and glucose-dependent insulinotropic polypeptide, are vital to the control of glucose homeostasis and pancreatic β-cell preservation. Novel strategies for the treatment of patients with type 2 diabetes mellitus (T2DM) engage the incretin system. Glucagon-like peptide-1 receptor agonists provide robust glycemic control as well as beneficial reductions in body weight. Dipeptidyl peptidase-4, or DPP-4, inhibitors exhibit beneficial glycemic effects and are weight-neutral. Incretin-based medications are becoming increasingly recognized in guidelines as early treatment options because of their efficacy and well-tolerated profiles. The author reviews the safety and efficacy of currently approved incretin-based agents, as well as the role of these medications in treatment paradigms for patients with T2DM. He also discusses investigational incretin-based agents.
