Механизм действия
Gonadorelin
Gonadorelin acts as an agonist at the GnRH receptor on the gonadotroph cells of the pituitary and triggers release of the gonadotropins luteinizing hormone (LH) and follicle-stimulating hormone (FSH). The temporal pattern of receptor exposure is decisive: pulsatile administration mimics the natural hypothalamic secretory rhythm and sustains LH/FSH release, whereas continuous exposure leads to receptor internalisation and desensitisation with subsequent paradoxical suppression of gonadotropins. The latter principle is exploited therapeutically by longer-acting GnRH agonists.
Teduglutid
Teduglutide activates the GLP-2 receptor, promoting growth and regeneration of small-intestinal villi, increasing nutrient and fluid absorption and thereby reducing dependence on parenteral nutrition. The glycine substitution at position 2 makes it resistant to rapid breakdown by DPP-4.

Frequently asked questions
- What is the difference between Gonadorelin and Teduglutid?
- Gonadorelin is classified as "Исследования (прочее)", while Teduglutid is classified as "Исследования (прочее)". Gonadorelin: Gonadorelin is the synthetic decapeptide with an amino-acid sequence identical to endogenous gonadotropin-releasing hormone (GnRH/LHRH). Historically approved in several countries for diagnostic testing of pituitary function and for fertility indications (pump systems). A defining feature is the opposite effect of pulsatile versus continuous administration: pulsatile stimulates, continuous leads to receptor desensitisation. Teduglutid: Teduglutide is a DPP-4-resistant analog of GLP-2 (glucagon-like peptide-2). It promotes growth and function of the intestinal mucosa and is approved for treating short bowel syndrome. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Gonadorelin or Teduglutid?
- The highest available evidence level is "Исследование на людях" for Gonadorelin and "РКИ на людях" for Teduglutid. 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 Gonadorelin and Teduglutid in Germany and the United States?
- Германия: Gonadorelin — Рецептурный, Teduglutid — Рецептурный. США: Gonadorelin — Рецептурный, Teduglutid — Рецептурный. These are factual summaries with source and review date on the individual pages.
