Механизм действия

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.

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 Cetrorelix and Triptorelin?: Cetrorelix is classified as "Исследования (прочее)", while Triptorelin is classified as "Исследования (прочее)". 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. 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, Cetrorelix or Triptorelin?: The highest available evidence level is "РКИ на людях" for Cetrorelix and "РКИ на людях" 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 Cetrorelix and Triptorelin in Germany and the United States?: Германия: Cetrorelix — Рецептурный, Triptorelin — Рецептурный. США: Cetrorelix — Рецептурный, Triptorelin — Рецептурный. These are factual summaries with source and review date on the individual pages.
