 [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.

vasoactive intestinal peptide (VIP), vasoactive intestinal polypeptide
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.

The trigeminovascular theory is one of the most persuasive theories in the pathogenesis of migraine, excessive internal and external stimulation can lead to vascular dilatation or vasomotor dysfunction, and the noxious stimulation accelerates the peripheral branch of trigeminal nerve releasing vasoactive substances and neurotransmitters, such as calcitonin gene-related peptide, P substance and 5-hydroxytryptamine, all of these will cause neurogenic inflammation, further lead to headache (Buzzi 1992; Welch et al.

These changes are caused by the release of spasmogens and vasoactive substances, including leukotrienes.
The paper, "Remodeling of an acellular collagen graft into a physiologically responsive neovessel", shows that the Company's non-living vascular graft is converted in the body into a living, cellularized vessel able to constrict and dilate in response to vasoactive substances.
Current treatments consist of penile prosthetic implants, use of vacuum devices or needle injection of vasoactive substances into the penis, including alprostadil (prostaglandin E1), a medication which increases penile blood flow.
