Meccanismo d'azione

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.

Triptorelin

Triptorelin binds with high affinity to the GnRH receptor in the pituitary. After initial stimulation of LH and FSH secretion (flare phase, about 1-2 weeks), receptor desensitisation follows with consecutive gonadotropin suppression. This results in a reversible chemical castration: in men testosterone, in women oestrogen suppression to the postmenopausal range.

Frequently asked questions

What is the difference between Nafarelin and Triptorelin?: Nafarelin is classified as "Ricerca (altro)", while Triptorelin is classified as "Ricerca (altro)". 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. Triptorelin: Synthetic decapeptide GnRH agonist with increased affinity over native gonadotropin-releasing hormone. FDA- and EMA-approved since the 1980s for prostate cancer, endometriosis and precocious puberty. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
Which peptide is better supported by science, Nafarelin or Triptorelin?: The highest available evidence level is "RCT sull'uomo" for Nafarelin and "RCT sull'uomo" for Triptorelin. 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 Triptorelin in Germany and the United States?: Germania: Nafarelin — Su prescrizione, Triptorelin — Su prescrizione. Stati Uniti: Nafarelin — Su prescrizione, Triptorelin — Su prescrizione. These are factual summaries with source and review date on the individual pages.
