Vasopressin agonists are used therapeutically in various conditions, and its long-acting synthetic analogue desmopressin is used in conditions featuring low vasopressin secretion, as well as for control of bleeding (in some forms of von Willebrand disease and in mild haemophilia A) and in extreme cases of bedwetting by children.
Selective vasopressin V2 antagonist (sometimes called aquaretics) tolvaptan , [ 15 ] conivaptan Competitive vasopressin antagonism leads to decreased number of aquaporin channels in the apical membrane of the renal collecting ducts in kidneys, causing decreased water reabsorption.
An antidiuretic is a substance that helps to control fluid balance in an animal's body by reducing urination, [1] opposing diuresis. [2] Its effects are opposite that of a diuretic.

Vasopressin analogues are synthetic peptides structurally and functionally similar to arginine vasopressin (AVP), a naturally occurring hormone in mammals. These compounds have been developed to target specific vasopressin receptors ( V1 , V2 , and V3 ) with varying affinities, allowing for more tailored therapeutic applications.
Vasopressin receptor antagonists (VRAs) are drugs that block vasopressin receptors. Most commonly VRAs are used to treat hyponatremia caused by syndrome of inappropriate antidiuretic hormone secretion (SIADH), congestive heart failure (CHF) and cirrhosis. [2] Somatostatin is a competitive inhibitor. [5]
Desmopressin (1-deamino-8-D-arginine vasopressin) is a synthetic form of the normal human hormone arginine vasopressin (the antidiuretic hormone, or ADH), a peptide containing nine amino acids. Compared to vasopressin, desmopressin's first amino acid has been deaminated , and the arginine at the eighth position is in the dextro rather than the ...
An antihypotensive, also known as vasopressor, is an agent that raises blood pressure by constricting blood vessels, thereby increasing systemic vascular resistance.This is different from inotropes which increase the force of cardiac contraction.
