Non-peptide GLP-1 agonist
What a GLP-1 receptor agonist actually does: which receptors it reaches, how it slows gastric emptying, and the satiety pathway it runs through.
Definition
A small organic molecule that switches on the GLP-1 receptor without being built from a peptide chain, so it survives stomach acid intact and needs none of the absorption scaffolding oral peptides require. Foundayo (orforglipron) was the first FDA-approved one, in April 2026.
