A non-peptide, small-molecule GLP-1 receptor agonist developed by Eli Lilly. Unlike semaglutide and tirzepatide which are peptides requiring injection, orforglipron is a fully oral pill taken once daily with no fasting requirement. Phase 3 trials are underway, potentially making it the first truly convenient oral GLP-1 option.
A dual GIP and GLP-1 receptor agonist developed by Eli Lilly. Represents the next generation of incretin-based therapies with potentially superior efficacy to semaglutide for weight loss.
Activates GLP-1 receptors through a non-peptide chemical scaffold, producing the same downstream effects as injectable GLP-1 agonists — appetite suppression, insulin secretion, and slowed gastric emptying. The oral bioavailability is achieved through its small-molecule structure, unlike oral semaglutide (Rybelsus) which requires strict fasting protocols.
Activates both GIP (glucose-dependent insulinotropic polypeptide) and GLP-1 receptors, producing enhanced insulin secretion, appetite suppression, and metabolic improvements beyond what single-agonist drugs achieve.

Currently in Phase 3 clinical trials for obesity and type 2 diabetes. Phase 2 results showed ~14.7% weight loss at 36 weeks — comparable to injectable semaglutide. If approved, would be the first non-peptide oral GLP-1 agonist, removing the injection barrier for many patients. Potential approval 2026-2027.
FDA-approved as Mounjaro (diabetes, 2022) and Zepbound (weight management, 2023).
