02 — How they work

Understanding the mechanisms.

GLP-1

Glucagon-like peptide-1 reduces appetite and slows gastric emptying. The foundation of this drug class.

GLP-1/GIP

Adding GIP (glucose-dependent insulinotropic polypeptide) enhances insulin secretion and may reduce nausea.

GLP-1/Glucagon

Glucagon component increases energy expenditure and may improve liver fat metabolism.

Triple Agonist

Combines GLP-1, GIP, and Glucagon for maximum metabolic impact across multiple pathways.

Amylin

Amylin analogs work on different satiety pathways, complementing GLP-1 effects.

Combination

CagriSema combines amylin (Cagrilintide) with GLP-1 (Semaglutide) for dual-pathway action.
