Pramlintide vs Cagrilintide

The first amylin analog — native amylin with its self-aggregation edited out. A long-acting amylin analog built for once-weekly dosing and GLP-1 pairing. 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 Pramlintide and Cagrilintide?
Pramlintide is an engineered analog based on Amylin; Cagrilintide is an engineered analog based on Amylin. Pramlintide signals at Amylin receptors (calcitonin receptor + RAMP); Cagrilintide signals at Amylin receptors (calcitonin receptor + RAMP).
How do the half-lives of Pramlintide and Cagrilintide compare?
The reported circulating half-life of Pramlintide is ~48 min; Cagrilintide is ~7 days (159-195 h). These are reference values for the native or representative form — educational only, not dosing advice.
Is Pramlintide the same as Symlin?
Symlin is a brand name of Pramlintide. This comparison describes the molecules, not branded products.
