Vasopressin: A synthetic analog of the pituitary hormone, ARGIPRESSIN. Its action is mediated by the vasopressin receptor V2. It has prolonged antidiuretic activity, but little pressor effects. It also modulates levels of circulating FACTOR VIII and VON WILLEBRAND FACTOR.

Vasopressin: octapeptide antidiuretic hormones released by the neurohypophysis of vertebrates; they control water metabolism and balance, contract smooth muscles, and may also be neurotransmitters.

Vasopressin: Antidiuretic hormones released by the NEUROHYPOPHYSIS of all vertebrates (structure varies with species) to regulate water balance and OSMOLARITY. In general, vasopressin is a nonapeptide consisting of a six-amino-acid ring with a cysteine 1 to cysteine 6 disulfide bridge or an octapeptide containing a CYSTINE. All mammals have arginine vasopressin except the pig with a lysine at position 8. Vasopressin, a vasoconstrictor, acts on the KIDNEY COLLECTING DUCTS to increase water reabsorption, increase blood volume and blood pressure.

Vasopressin (organ): Vasopressin is one of the pituitary hormones, chemical substances made and/or stored by the three lobes of the pituitary gland. Vasopressin is produced by the hypothalamus and stored in the posterior lobe of the pituitary gland. Its function is to increase water reabsorption in the kidney and decrease sweating, helping to regulate water levels in the body. Vasopressin also causes vasoconstriction of small arteries in response to low blood pressure.
Vasopressin release is stimulated by the hypothalamus. Conditions that can afflict vasopressin include ADH deficiency, empty sella syndrome, adenoma, hypopituitarism, and head trauma.
Vasopressin (organ): See Vasopressin (organ information).
