Somatostatin vs Lanreotide

The brake on the growth-hormone axis — and much else. A depot somatostatin analog, similar in action to octreotide. 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 Somatostatin and Lanreotide?
Somatostatin is an endogenous hormone; Lanreotide is an engineered analog based on Somatostatin. Somatostatin signals at Somatostatin receptors SSTR1–SSTR5; Lanreotide signals at Somatostatin receptors (SSTR2 and SSTR5 preferential).
How do the half-lives of SST and Lanreotide compare?
The reported circulating half-life of Somatostatin is ~1–3 min (very short); Lanreotide is depot-dominant (autogel acts over weeks). These are reference values for the native or representative form — educational only, not dosing advice.
