Vasopressin is a cyclic nonapeptide that is synthesized centrally in the hypothalamus. Vasopressin participates in the hypothalamic-pituitary-adrenal axis, and regulates pituitary corticotropin secretion by potentiating the stimulatory effects of corticotropin releasing factor. Vasopressin also can act as a neurotransmitter, exerting its action by binding to specific G protein-coupled receptors^[1][2][3].

AVP (0.01 nM-1 μM) induces Ca²⁺ increase in Chinese hamster ovary cells expressing rat or human V_1b receptors^[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Vasopressin (0.03-0.3 μg/kg; i.p.) potentiates corticotropin release provoked by exogenous corticoliberin and increases corticotropin secretion subsequent to body water loss^[2].
Vasopressin (0.001-0.1 mg/kg; i.p.) potently increases adjacent lying, where rats meeting for the first time lie passively next to each other^[3].
