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.

Octreotide

Octreotide is a cyclic octapeptide that selectively binds somatostatin-receptor subtypes SSTR2 and SSTR5. Via G-protein-coupled signalling, adenylyl cyclase is inhibited, reducing the secretion of multiple hormones (growth hormone, IGF-1, glucagon, insulin, VIP, serotonin). Structural stabilisation via a disulfide bridge and D-amino acids extends the half-life relative to natural somatostatin (minutes to several hours).

Frequently asked questions

What is the difference between Cetrorelix and Octreotide?: Cetrorelix is classified as "Исследования (прочее)", while Octreotide 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. Octreotide: Synthetic octapeptide somatostatin analog with a longer half-life than endogenous somatostatin. FDA- and EMA-approved since the 1980s for acromegaly and neuroendocrine tumours. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
Which peptide is better supported by science, Cetrorelix or Octreotide?: The highest available evidence level is "РКИ на людях" for Cetrorelix and "РКИ на людях" for Octreotide. 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 Octreotide in Germany and the United States?: Германия: Cetrorelix — Рецептурный, Octreotide — Рецептурный. США: Cetrorelix — Рецептурный, Octreotide — Рецептурный. These are factual summaries with source and review date on the individual pages.
