Choosing GLP-1 Receptor Agonists or DPP-4 Inhibitors: Weighing the Clinical Trial Evidence

Abstract

IN BRIEF Comparative trials show that there are important differences between and among the glucagon-like peptide-1 (GLP-1) receptor agonists and dipeptidyl peptidase-4 (DPP-4) inhibitors with respect to glycemic lowering, weight effects, and effects on systolic blood pressure and the lipid profile. Nausea, diarrhea, headaches, and dizziness are common with both of the available GLP-1 receptor agonists. Upper respiratory tract infections, nasopharyngitis, and headaches are common with the DPP-4 inhibitors. Ongoing safety evaluations should provide a clear picture regarding long-term safety.
