Mechanism of action
CagriSema
CagriSema combines two satiety pathways in one weekly injection: the amylin analogue cagrilintide and the GLP-1 agonist semaglutide. Both suppress appetite and food intake — together more than either component alone.
Petrelintide
As an amylin analogue, petrelintide acts through amylin receptors, promoting satiety and slowed gastric emptying — a satiety pathway independent of the GLP-1 axis.

Frequently asked questions
- What is the difference between CagriSema and Petrelintide?
- CagriSema is classified as "Metabolic", while Petrelintide is classified as "Metabolic". CagriSema: CagriSema is a fixed-dose combination of the amylin analogue cagrilintide and the GLP-1 agonist semaglutide (Novo Nordisk), in late-stage development for obesity and type 2 diabetes. Petrelintide: Petrelintide is a long-acting amylin analogue (Zealand Pharma, with Roche) for once-weekly subcutaneous use — developed for weight management with a focus on strong tolerability. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, CagriSema or Petrelintide?
- The highest available evidence level is "Human RCT" for CagriSema and "Human RCT" for Petrelintide. 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 CagriSema and Petrelintide in Germany and the United States?
- Germany: CagriSema — Unapproved, Petrelintide — Unapproved. United States: CagriSema — Unapproved, Petrelintide — Unapproved. These are factual summaries with source and review date on the individual pages.
