An endogenous antidiuretic hormone in most mammalian species. Arginine Vasopressin Diacetate is released into the blood from nerve terminals in the posterior pituitary and median eminence. It is a neurotransmitter in the central nervous system and also implicated in a variety of physiological processes such as regulating water balance by antidiuretic action. Arginine Vasopressin Diacetate is a peptidic V1a receptor agonist that produces vasoconstrictio n via V1aR-mediated vascular smooth muscle cell contraction and is being used to increase blood pressure in septic shock, a form of vasodilatory hypotension.
