Werkingsmechanisme
Degarelix
Degarelix is a competitive GnRH receptor antagonist. It binds reversibly and immediately to the pituitary GnRH receptors and blocks their activation. This rapidly suppresses the release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which in turn lowers testosterone production in the testes. Unlike GnRH agonists (e.g., leuprorelin), which first cause a transient stimulation with a testosterone surge (flare), this direct antagonism lacks the initial stimulation phase, so testosterone declines without a preceding rise. This mechanism underlies the literature-described use in hormone-dependent prostate cancer.
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 Degarelix and Plecanatid?
- Degarelix is classified as "Onderzoek (overig)", while Plecanatid is classified as "Onderzoek (overig)". Degarelix: Degarelix (trade name Firmagon) is a synthetic decapeptide and a gonadotropin-releasing hormone (GnRH) receptor antagonist. Unlike GnRH agonists, it blocks the receptor directly and does not trigger an initial testosterone surge (flare). It is an approved prescription medicine for the treatment of advanced, hormone-dependent prostate cancer. 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, Degarelix or Plecanatid?
- The highest available evidence level is "Humane RCT" for Degarelix and "Humane RCT" 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 Degarelix and Plecanatid in Germany and the United States?
- Duitsland: Degarelix — Op recept, Plecanatid — Niet goedgekeurd. Verenigde Staten: Degarelix — Op recept, Plecanatid — Op recept. These are factual summaries with source and review date on the individual pages.
