Mechanism of action
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.
Pemvidutide
The GLP-1 component suppresses appetite while the glucagon component raises energy expenditure and acts directly on hepatic fat metabolism — the combination is intended to mimic the complementary effects of diet and exercise.

Frequently asked questions
- What is the difference between Glucagon and Pemvidutide?
- Glucagon is classified as "Metabolic", while Pemvidutide is classified as "Metabolic". 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. Pemvidutide: Pemvidutide is a 29-amino-acid GLP-1/glucagon dual receptor agonist (Altimmune) under investigation for obesity and the fatty-liver disease MASH. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Glucagon or Pemvidutide?
- The highest available evidence level is "Human RCT" for Glucagon and "Human trial" for Pemvidutide. 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 Pemvidutide in Germany and the United States?
- Germany: Glucagon — Prescription, Pemvidutide — Unapproved. United States: Glucagon — Prescription, Pemvidutide — Unapproved. These are factual summaries with source and review date on the individual pages.
