Werkingsmechanisme

Nafarelin

Nafarelin is a potent GnRH agonist: after an initial stimulation ('flare'), continuous receptor occupancy leads to downregulation and thereby suppression of LH, FSH and the downstream sex hormones.

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).

Frequently asked questions

What is the difference between Nafarelin and Octreotide?: Nafarelin is classified as "Onderzoek (overig)", while Octreotide is classified as "Onderzoek (overig)". Nafarelin: Nafarelin is a GnRH agonist and the only member of this class delivered as a nasal spray. It is approved for treating endometriosis and central precocious puberty. 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. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
Which peptide is better supported by science, Nafarelin or Octreotide?: The highest available evidence level is "Humane RCT" for Nafarelin and "Humane RCT" for Octreotide. 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 Nafarelin and Octreotide in Germany and the United States?: Duitsland: Nafarelin — Op recept, Octreotide — Op recept. Verenigde Staten: Nafarelin — Op recept, Octreotide — Op recept. These are factual summaries with source and review date on the individual pages.
