Cagrilintide
Cagrilintide binds amylin receptors (AMY1, AMY3, formed by the calcitonin receptor plus RAMP proteins). Activation delays gastric emptying, inhibits postprandial glucagon secretion and modulates central satiety signalling via area postrema neurons. An acyl modification enables albumin binding and thereby weekly dosing.
Glucagon
Glucagon is produced in the alpha cells of the pancreas (islets of Langerhans) and released when blood sugar is low. Glucagon binds the glucagon receptor (GCGR), a G-protein-coupled receptor expressed predominantly on hepatocytes. Activation stimulates adenylate cyclase, raises cyclic AMP and activates protein kinase A. This drives glycogenolysis (breakdown of hepatic glycogen into glucose) and gluconeogenesis (de novo glucose synthesis), which raises blood glucose. Glucagon also promotes lipolysis. As the counterpart to insulin it contributes to glucose homeostasis. It transiently relaxes gastrointestinal smooth muscle, which is the basis of its diagnostic use in imaging.

Frequently asked questions
- What is the difference between Cagrilintide and Glucagon?
- Cagrilintide is classified as "Metabool", while Glucagon is classified as "Metabool". Cagrilintide: Synthetic long-acting amylin analog being developed in combination with semaglutide (CagriSema). Phase 3 trials for obesity and type 2 diabetes are ongoing. No marketing approval yet. Glucagon: Glucagon is a 29-amino-acid pancreatic hormone produced by the alpha cells of the islets of Langerhans. It is the physiological counterpart to insulin and raises blood glucose via hepatic glycogenolysis and gluconeogenesis. It is approved as an emergency treatment for severe hypoglycaemia and as a diagnostic aid; its receptor is also a target of modern dual and triple incretin agonists. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Cagrilintide or Glucagon?
- The highest available evidence level is "Humane RCT" for Cagrilintide and "Humane RCT" for Glucagon. A higher evidence level means more robust data, but says nothing about suitability for an individual. The full body of evidence is on each peptide's own page.
- What is the legal status of Cagrilintide and Glucagon in Germany and the United States?
- Duitsland: Cagrilintide — Niet goedgekeurd, Glucagon — Op recept. Verenigde Staten: Cagrilintide — Niet goedgekeurd, Glucagon — Op recept. These are factual summaries with source and review date on the individual pages.
