Meccanismo d'azione

Cetrorelix

Cetrorelix competitively and immediately blocks the pituitary GnRH receptor, rapidly suppressing LH and FSH release — without the initial hormone surge ('flare') of GnRH agonists.

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.

Frequently asked questions

What is the difference between Cetrorelix and Nafarelin?: Cetrorelix is classified as "Ricerca (altro)", while Nafarelin is classified as "Ricerca (altro)". Cetrorelix: Cetrorelix is a synthetic decapeptide and GnRH antagonist. It is used in assisted reproduction (IVF) to prevent a premature LH surge during controlled ovarian stimulation. 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. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
Which peptide is better supported by science, Cetrorelix or Nafarelin?: The highest available evidence level is "RCT sull'uomo" for Cetrorelix and "RCT sull'uomo" for Nafarelin. 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 Cetrorelix and Nafarelin in Germany and the United States?: Germania: Cetrorelix — Su prescrizione, Nafarelin — Su prescrizione. Stati Uniti: Cetrorelix — Su prescrizione, Nafarelin — Su prescrizione. These are factual summaries with source and review date on the individual pages.
