Механизм действия

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.

Histrelin

Continuous GnRH-agonist stimulation downregulates and desensitises the pituitary GnRH receptors — after the initial rise, LH, FSH and the sex hormones fall persistently.

Frequently asked questions

What is the difference between Buserelin and Histrelin?: Buserelin is classified as "Исследования (прочее)", while Histrelin is classified as "Исследования (прочее)". 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. Histrelin: Histrelin is a nonapeptide GnRH agonist delivered as a once-yearly implant. Approved for central precocious puberty in children (Supprelin LA) and advanced prostate cancer (Vantas). This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
Which peptide is better supported by science, Buserelin or Histrelin?: The highest available evidence level is "РКИ на людях" for Buserelin and "РКИ на людях" for Histrelin. 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 Histrelin in Germany and the United States?: Германия: Buserelin — Рецептурный, Histrelin — Рецептурный. США: Buserelin — Не одобрено, Histrelin — Рецептурный. These are factual summaries with source and review date on the individual pages.
