Механизм действия
Octreotide
Octreotide is a cyclic octapeptide that selectively binds somatostatin-receptor subtypes SSTR2 and SSTR5. Via G-protein-coupled signalling, adenylyl cyclase is inhibited, reducing the secretion of multiple hormones (growth hormone, IGF-1, glucagon, insulin, VIP, serotonin). Structural stabilisation via a disulfide bridge and D-amino acids extends the half-life relative to natural somatostatin (minutes to several hours).
Terlipressin
Terlipressin is slowly converted in the body to lysine-vasopressin by cleavage of the three N-terminal glycyl residues (reservoir effect) and activates V1 receptors. The splanchnic vasoconstriction improves renal perfusion in hepatorenal syndrome.

Frequently asked questions
- What is the difference between Octreotide and Terlipressin?
- Octreotide is classified as "Исследования (прочее)", while Terlipressin is classified as "Исследования (прочее)". Octreotide: Synthetic octapeptide somatostatin analog with a longer half-life than endogenous somatostatin. FDA- and EMA-approved since the 1980s for acromegaly and neuroendocrine tumours. Terlipressin: Terlipressin is a 12-amino-acid vasopressin analog and prodrug of lysine-vasopressin. As a V1 receptor agonist it is vasoconstrictive and is approved for hepatorenal syndrome (FDA 2022, Terlivaz). This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Octreotide or Terlipressin?
- The highest available evidence level is "РКИ на людях" for Octreotide and "РКИ на людях" for Terlipressin. A higher evidence level means more robust data, but says nothing about suitability for an individual. The full body of evidence is on each peptide's own page.
- What is the legal status of Octreotide and Terlipressin in Germany and the United States?
- Германия: Octreotide — Рецептурный, Terlipressin — Рецептурный. США: Octreotide — Рецептурный, Terlipressin — Рецептурный. These are factual summaries with source and review date on the individual pages.
