Pasireotide vs Somatostatin
A broader-spectrum somatostatin analog hitting more receptor subtypes. The brake on the growth-hormone axis — and much else. 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 Pasireotide and Somatostatin?
- Pasireotide is an engineered analog based on Somatostatin; Somatostatin is an endogenous hormone. Pasireotide signals at Somatostatin receptors (SSTR1, 2, 3, and 5); Somatostatin signals at Somatostatin receptors SSTR1–SSTR5.
- How do the half-lives of Pasireotide and SST compare?
- The reported circulating half-life of Pasireotide is ~12 h; Somatostatin is ~1–3 min (very short). These are reference values for the native or representative form — educational only, not dosing advice.
- Is Pasireotide the same as Signifor?
- Signifor is a brand name of Pasireotide. This comparison describes the molecules, not branded products.
