Liraglutide
Established GLP-1 with long history (15+ years) but requires daily injection. Cheaper than newer GLP-1s.

Both are metabolic but target different receptors. Liraglutide is first-generation GLP-1 (Saxenda/Victoza, FDA 2010). Cagrilintide is a long-acting amylin analog — a new mechanism category, developed as a Semaglutide partner (CagriSema).

| FDA status | Approved (Saxenda 2014, Victoza 2010) | Phase 3 (REDEFINE trials) |
| Dosing | 1.8-3.0 mg s.c. daily | 2.4 mg s.c. 1× weekly |
| Half-life | ~13 hours | ~7 days |

| In combination | Doesn't stack with other GLP-1s | CagriSema (+ Semaglutide) → 22% / 32 weeks |

Novel mechanism category. The real strength is the Semaglutide stack (CagriSema) — strongest Phase 2 weight loss to date.

Liraglutide is an aging classic; Cagrilintide is the new addition, especially when stacked with GLP-1. Not direct substitutes — different receptors.
