Meccanismo d'azione
Degarelix
Degarelix is a competitive GnRH receptor antagonist. It binds reversibly and immediately to the pituitary GnRH receptors and blocks their activation. This rapidly suppresses the release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which in turn lowers testosterone production in the testes. Unlike GnRH agonists (e.g., leuprorelin), which first cause a transient stimulation with a testosterone surge (flare), this direct antagonism lacks the initial stimulation phase, so testosterone declines without a preceding rise. This mechanism underlies the literature-described use in hormone-dependent prostate cancer.
Ganirelix
Ganirelix competitively and reversibly binds the pituitary GnRH receptor, rapidly suppressing LH (and, less so, FSH) release — without the initial hormone 'flare' of GnRH agonists.

Frequently asked questions
- What is the difference between Degarelix and Ganirelix?
- Degarelix is classified as "Ricerca (altro)", while Ganirelix is classified as "Ricerca (altro)". Degarelix: Degarelix (trade name Firmagon) is a synthetic decapeptide and a gonadotropin-releasing hormone (GnRH) receptor antagonist. Unlike GnRH agonists, it blocks the receptor directly and does not trigger an initial testosterone surge (flare). It is an approved prescription medicine for the treatment of advanced, hormone-dependent prostate cancer. This page neutrally summarizes the evidence base and legal status and is not a usage or dosing recommendation. Ganirelix: Ganirelix is a synthetic decapeptide and GnRH antagonist. In assisted reproduction (IVF) it prevents the premature LH surge during controlled ovarian stimulation. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Degarelix or Ganirelix?
- The highest available evidence level is "RCT sull'uomo" for Degarelix and "RCT sull'uomo" for Ganirelix. 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 Degarelix and Ganirelix in Germany and the United States?
- Germania: Degarelix — Su prescrizione, Ganirelix — Su prescrizione. Stati Uniti: Degarelix — Su prescrizione, Ganirelix — Su prescrizione. These are factual summaries with source and review date on the individual pages.
