Meccanismo d'azione
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.
Pramlintid
Pramlintide mimics the beta-cell hormone amylin, which is co-secreted with insulin. It slows gastric emptying, suppresses postprandial glucagon release and promotes satiety — thereby blunting post-meal blood-glucose spikes.

Frequently asked questions
- What is the difference between Glucagon and Pramlintid?
- Glucagon is classified as "Metabolico", while Pramlintid is classified as "Metabolico". 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. Pramlintid: Pramlintide is a synthetic analog of the hormone amylin. It is used as an adjunct to mealtime insulin therapy in type 1 and type 2 diabetes and, among other things, slows gastric emptying. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Glucagon or Pramlintid?
- The highest available evidence level is "RCT sull'uomo" for Glucagon and "RCT sull'uomo" for Pramlintid. 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 Pramlintid in Germany and the United States?
- Germania: Glucagon — Su prescrizione, Pramlintid — Non approvato. Stati Uniti: Glucagon — Su prescrizione, Pramlintid — Su prescrizione. These are factual summaries with source and review date on the individual pages.
