Mechanism of action
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.
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 Plecanatid and Vasopressin?
- Plecanatid is classified as "Research other", while Vasopressin is classified as "Research other". 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). 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, Plecanatid or Vasopressin?
- The highest available evidence level is "Human RCT" for Plecanatid and "Human 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 Plecanatid and Vasopressin in Germany and the United States?
- Germany: Plecanatid — Unapproved, Vasopressin — Prescription. United States: Plecanatid — Prescription, Vasopressin — Prescription. These are factual summaries with source and review date on the individual pages.
