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 ...
V 1 receptors (V 1 Rs) are found in high density on vascular smooth muscle and cause vasoconstriction by an increase in intracellular calcium via the phosphatidyl–inositol-bisphosphate cascade. [1] Cardiac myocytes also possess V 1 R. Additionally V 1 R are located in brain , testis , superior cervical ganglion , liver , blood vessels , and ...
The "vaptan" drugs act by directly blocking the action of vasopressin at its receptors (V 1A, V 1B and V 2).These receptors have a variety of functions, with the V 1A and V 2 receptors are expressed peripherally and involved in the modulation of blood pressure and kidney function respectively, while the V 1A and V 1B receptors are expressed in the central nervous system.
A fluid or water deprivation test is a medical test [1] which can be used to determine whether the patient has diabetes insipidus as opposed to other causes of polydipsia (a condition of excessive thirst that causes an excessive intake of water). The patient is required, for a prolonged period, to forgo intake of water completely, to determine ...

AVPR2 is also expressed outside the kidney in vascular endothelium. [6] Stimulation causes the release of von Willebrand factor and factor VIII from the endothelial cells. [ 6 ] Because von Willebrand factor helps stabilize circulating levels of factor VIII, the vasopressin analog desmopressin can be used to stimulate the AVPR2 receptor and ...
