Механизм действия
Leuprorelin
Leuprorelin is a GnRH-receptor agonist. After binding to pituitary GnRH receptors, it first causes a transient surge in luteinizing hormone (LH) and follicle-stimulating hormone (FSH) release — the so-called flare. With continuous, non-pulsatile exposure the receptors are downregulated and desensitized, suppressing gonadotropin secretion and consequently lowering sex steroids (testosterone or estradiol) to low levels. This mechanism underlies the literature-described use in hormone-dependent conditions.
Plecanatid
Plecanatide is structurally analogous to the body's own uroguanylin and, like it, activates the GC-C receptor at the gut surface, raising cGMP and fluid secretion. Its pH-dependent activity shifts the effect toward the proximal small intestine.

Frequently asked questions
- What is the difference between Leuprorelin and Plecanatid?
- Leuprorelin is classified as "Исследования (прочее)", while Plecanatid is classified as "Исследования (прочее)". Leuprorelin: Leuprorelin (also leuprolide) is a synthetic nonapeptide analogue of gonadotropin-releasing hormone (GnRH/LHRH). It is an approved prescription medicine in several jurisdictions, including for advanced prostate cancer, endometriosis, uterine fibroids and central precocious puberty. This page neutrally summarizes the evidence base and legal status and is not a usage or dosing recommendation. Plecanatid: Plecanatide is a 16-amino-acid analog of the body's own uroguanylin and a guanylate cyclase-C (GC-C) agonist. It is approved for chronic idiopathic constipation (CIC) and IBS with constipation (IBS-C). This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Leuprorelin or Plecanatid?
- The highest available evidence level is "РКИ на людях" for Leuprorelin and "РКИ на людях" for Plecanatid. 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 Leuprorelin and Plecanatid in Germany and the United States?
- Германия: Leuprorelin — Рецептурный, Plecanatid — Не одобрено. США: Leuprorelin — Рецептурный, Plecanatid — Рецептурный. These are factual summaries with source and review date on the individual pages.
