An endogenous antidiuretic hormone used clinically as a non-adrenergic vasopressor to increase mean arterial pressure via V1a-mediated vasoconstriction and promote renal water reabsorption via V2 receptors. In hospital practice, it is most commonly used as a fixed-dose adjunct to norepinephrine in septic or vasodilatory shock, particularly in catecholamine-refractory hypotension, with key risks including ischemia and hyponatremia.
