Carbetocin
Carbetocin is an oxytocin receptor agonist with prolonged duration. It triggers a sustained contraction of the uterus after birth, preventing atonic hemorrhage — unlike oxytocin, without a multi-hour infusion.
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.

Frequently asked questions
- What is the difference between Carbetocin and Gonadorelin?
- Carbetocin is classified as "Исследования (прочее)", while Gonadorelin is classified as "Исследования (прочее)". Carbetocin: Carbetocin is a long-acting synthetic oxytocin analog (half-life ~40 minutes). It prevents postpartum hemorrhage as a single injection. Approved in Canada and the UK among others, NOT in the US. 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. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Carbetocin or Gonadorelin?
- The highest available evidence level is "РКИ на людях" for Carbetocin and "Исследование на людях" for Gonadorelin. 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 Carbetocin and Gonadorelin in Germany and the United States?
- Германия: Carbetocin — Рецептурный, Gonadorelin — Рецептурный. США: Carbetocin — Не одобрено, Gonadorelin — Рецептурный. These are factual summaries with source and review date on the individual pages.
