Dulaglutide
Dulaglutide consists of two modified GLP-1(7-37) sequences covalently linked to a human IgG4-Fc. The Fc fusion increases molecular weight substantially (~60 kDa), reduces renal filtration and extends the half-life to several days. GLP-1 receptor activation glucose-dependently stimulates insulin secretion, inhibits glucagon, delays gastric emptying and modulates central satiety signalling.
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 Dulaglutide and Glucagon?
- Dulaglutide is classified as "Metabolico", while Glucagon is classified as "Metabolico". Dulaglutide: GLP-1 receptor agonist designed as a fusion protein of two modified GLP-1(7-37) sequences covalently linked to a human IgG4-Fc fragment. FDA-approved 2014 (Trulicity) for type 2 diabetes; EMA approval 2014. 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, Dulaglutide or Glucagon?
- The highest available evidence level is "RCT sull'uomo" for Dulaglutide and "RCT sull'uomo" 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 Dulaglutide and Glucagon in Germany and the United States?
- Germania: Dulaglutide — Su prescrizione, Glucagon — Su prescrizione. Stati Uniti: Dulaglutide — Su prescrizione, Glucagon — Su prescrizione. These are factual summaries with source and review date on the individual pages.
