Meccanismo d'azione

Buserelin

Buserelin is a potent GnRH agonist: after an initial stimulatory surge ('flare'), continuous receptor occupancy causes downregulation and thereby suppression of LH, FSH and the downstream sex hormones.

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.

Frequently asked questions

What is the difference between Buserelin and Cetrorelix?: Buserelin is classified as "Ricerca (altro)", while Cetrorelix is classified as "Ricerca (altro)". Buserelin: Buserelin is a synthetic GnRH agonist (including as a nasal spray). It is used in endometriosis, hormone-dependent prostate cancer and assisted reproduction; approved in Europe (Suprefact), not in the US. 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. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
Which peptide is better supported by science, Buserelin or Cetrorelix?: The highest available evidence level is "RCT sull'uomo" for Buserelin and "RCT sull'uomo" for Cetrorelix. 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 Buserelin and Cetrorelix in Germany and the United States?: Germania: Buserelin — Su prescrizione, Cetrorelix — Su prescrizione. Stati Uniti: Buserelin — Non approvato, Cetrorelix — Su prescrizione. These are factual summaries with source and review date on the individual pages.
