Cagrilintide vs Semaglutide
A long-acting amylin analog built for once-weekly dosing and GLP-1 pairing. A long-acting GLP-1 receptor agonist engineered for once-weekly dosing. Side by side: type, evidence tier, receptor, molecular weight, and half-life — the same fields as each monograph, rearranged so the engineering difference is visible.

Common questions
- What is the difference between Cagrilintide and Semaglutide?
- Cagrilintide is an engineered analog based on Amylin; Semaglutide is an engineered analog based on Glucagon-like peptide-1. Cagrilintide signals at Amylin receptors (calcitonin receptor + RAMP); Semaglutide signals at GLP-1 receptor (GLP-1R).
- How do the half-lives of Cagrilintide and Semaglutide compare?
- The reported circulating half-life of Cagrilintide is ~7 days (159-195 h); Semaglutide is ~7 days (~165 h). These are reference values for the native or representative form — educational only, not dosing advice.
