Механизм действия

Goserelin

As a GnRH agonist, goserelin binds to the GnRH receptors of the pituitary gland. Initial stimulation transiently raises luteinizing hormone (LH) and follicle-stimulating hormone (FSH). With continuous receptor occupancy, however, the receptors become desensitized and down-regulated, which reduces LH and FSH secretion and consequently the production of testosterone or estrogen. This mechanistic relationship is documented in the pharmacological literature.

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 Goserelin and Nafarelin?: Goserelin is classified as "Исследования (прочее)", while Nafarelin is classified as "Исследования (прочее)". Goserelin: Goserelin is a synthetic decapeptide and an agonist of gonadotropin-releasing hormone (GnRH). The medical literature describes it as a hormonal agent that suppresses the release of sex hormones through sustained receptor stimulation. Regulatory-approved indications include prostate cancer, advanced breast cancer, endometriosis, and endometrial thinning, among others. 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, Goserelin or Nafarelin?: The highest available evidence level is "РКИ на людях" for Goserelin and "РКИ на людях" 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 Goserelin and Nafarelin in Germany and the United States?: Германия: Goserelin — Рецептурный, Nafarelin — Рецептурный. США: Goserelin — Рецептурный, Nafarelin — Рецептурный. These are factual summaries with source and review date on the individual pages.
