Orforglipron
Orforglipron is a first-in-class oral non-peptide GLP-1 receptor agonist that eliminates the need for injections entirely. Unlike semaglutide (Rybelsus), which is a peptide requiring specific absorption-enhancing formulation, orforglipron is a small molecule that is readily absorbed orally without dietary restrictions. Phase 3 trials have demonstrated 8-14% body weight loss and significant improvements in glycemic control. Its oral convenience and lack of injection-related barriers could dramatically increase GLP-1 therapy adoption. Orforglipron can be taken daily as a simple pill, making it the most accessible GLP-1 agonist option.
