vasoactive

 [vas″o-ak´tiv]
exerting an effect upon the caliber of blood vessels.
vasoactive intestinal polypeptide (VIP) a peptide hormone that, in addition to its vasoactive properties, stimulates intestinal secretion of water and electrolytes, inhibits gastric secretion, promotes glycogenesis, causes hyperglycemia, and stimulates production of pancreatic juice. See also vipoma.

a peptide hormone that, in addition to its vasoactive properties, stimulates intestinal secretion of water and electrolytes, inhibits gastric secretion, promotes glycogenesis, causes hyperglycemia and stimulates secretion of pancreatic juice.
vasoactive substances
substances which cause constriction of blood vessels; substances which actively dilate vessels, rather than relax an existing vasoconstriction, should be included. See vasoconstrictor agents and vasodilator agents.
vasoactive substances, endothelium-derived
includes nitrous oxide, prostacyclin and other prostanoids, unnamed relaxing or constricting factors released as a result of a tissue insult, e.g. hypoxia or excessive stretch.
