Glucagon-like peptide 1 (GLP-1) receptor agonists are a class of medications known as themost widely used drugs for the treatment of T2DM because of their cardiovascular and metabolic benefits, such as improved cardiac capacity and significant weight loss.[4] These medications include metformin, which is still regarded as first-line therapy for treating T2DM. Here, GCG is linked to type 2 diabetes mellitus.
