Mechanism of action
Pharmacology class
GLP-1 receptor agonist
Semaglutide selectively binds the GLP-1 receptor with 94% homology to native human GLP-1, augmenting glucose-dependent insulin secretion from pancreatic beta-cells, suppressing inappropriate glucagon release, slowing gastric emptying, and reducing appetite via central pathways.

- T-max
- 1–3 days
- Metabolism

- Excretion
- Renal and fecal
- Bioavailability
