Werkingsmechanisme
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.
Vasopressin
Vasopressin binds V1 receptors (vasoconstriction, raising vascular resistance) and V2 receptors (renal water reabsorption via aquaporin channels). This raises blood pressure and acts antidiuretically. Desmopressin is the V2-selective synthetic analog.

Frequently asked questions
- What is the difference between Leuprorelin and Vasopressin?
- Leuprorelin is classified as "Onderzoek (overig)", while Vasopressin is classified as "Onderzoek (overig)". 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. Vasopressin: Vasopressin (arginine vasopressin, antidiuretic hormone/ADH) is a cyclic nonapeptide hormone that regulates water balance and vascular tone. As Vasostrict it is approved to raise blood pressure in vasodilatory shock. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
- Which peptide is better supported by science, Leuprorelin or Vasopressin?
- The highest available evidence level is "Humane RCT" for Leuprorelin and "Humane RCT" for Vasopressin. 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 Vasopressin in Germany and the United States?
- Duitsland: Leuprorelin — Op recept, Vasopressin — Op recept. Verenigde Staten: Leuprorelin — Op recept, Vasopressin — Op recept. These are factual summaries with source and review date on the individual pages.
