Werkingsmechanisme
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.
Maridebart Cafraglutide
MariTide combines GLP-1 receptor agonism with GIP receptor antagonism in an antibody-peptide conjugate. Its long duration of action allows infrequent (monthly) dosing.

Frequently asked questions
- What is the difference between Glucagon and Maridebart Cafraglutide?
- Glucagon is classified as "Metabool", while Maridebart Cafraglutide is classified as "Metabool". 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. Maridebart Cafraglutide: Maridebart cafraglutide (MariTide, Amgen) is a bispecific molecule: a GLP-1 receptor agonist combined with a GIP receptor antagonist, designed for monthly dosing; in phase 3 for obesity. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Glucagon or Maridebart Cafraglutide?
- The highest available evidence level is "Humane RCT" for Glucagon and "Humane RCT" for Maridebart Cafraglutide. 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 Glucagon and Maridebart Cafraglutide in Germany and the United States?
- Duitsland: Glucagon — Op recept, Maridebart Cafraglutide — Niet goedgekeurd. Verenigde Staten: Glucagon — Op recept, Maridebart Cafraglutide — Niet goedgekeurd. These are factual summaries with source and review date on the individual pages.
