Meccanismo d'azione
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).
Vasopressin
Vasopressin binds V1 receptors (vasoconstriction, raising vascular resistance) and V2 receptors (renal water reabsorption via aquaporin channels). This raises blood pressure and acts antidiuretically. Desmopressin is the V2-selective synthetic analog.

Frequently asked questions
- What is the difference between Octreotide and Vasopressin?
- Octreotide is classified as "Ricerca (altro)", while Vasopressin is classified as "Ricerca (altro)". 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. Vasopressin: Vasopressin (arginine vasopressin, antidiuretic hormone/ADH) is a cyclic nonapeptide hormone that regulates water balance and vascular tone. As Vasostrict it is approved to raise blood pressure in vasodilatory shock. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Octreotide or Vasopressin?
- The highest available evidence level is "RCT sull'uomo" for Octreotide and "RCT sull'uomo" for Vasopressin. 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 Vasopressin in Germany and the United States?
- Germania: Octreotide — Su prescrizione, Vasopressin — Su prescrizione. Stati Uniti: Octreotide — Su prescrizione, Vasopressin — Su prescrizione. These are factual summaries with source and review date on the individual pages.
