Mode Of Action. A mode of action (MoA) describes a functional or anatomical change, at the cellular level, resulting from the exposure of a living organism to a substance. In comparison, a mechanism of action (MOA) describes such changes at the molecular level. A mode of action is important in classifying chemicals as it represents an intermediate level of complexity in between molecular

Vasopressin (Antidiuretic Hormone) Vasopressin (arginine vasopressin, AVP; antidiuretic hormone, ADH) is a peptide hormone formed in the hypothalamus, then transported via axons to the posterior pituitary, which releases it into the blood. AVP has two principle sites of action: the kidney and blood vessels. 2013-08-28 · Vasopressin Drug Class: Vasoconstrictor & Anti-Diuretic Hormone (ADH) Mechanism of Action: Supraphysiologic concentrations: vasopressin constricts arterial blood vessels by binding to Supraphysiologic concentrations: vasopressin constricts arterial blood vessels by binding to vascular V 1 Vasopressin on multiple receptors (GPCRs; g protein coupled receptors) (Holmes et al, 2003) V1 vascular smooth muscle of the systemic, splanchnic, renal, and coronary circulations -> potent vasoconstriction vasoconstriction of renal efferent arterioles -> increased GFR Vasopressin binding to cause vasoconstriction (source) Vasopressin binds to receptors of it's target cells in the kidney tubules and vascular smooth muscle. Vasopressin can bind with 3 different receptors V1A, V1B, and V2.[4].

Vasopressin mechanism of action

Vasopressin binding to cause vasoconstriction (source) Vasopressin binds to receptors of it's target cells in the kidney tubules and vascular smooth muscle. Vasopressin can bind with 3 different receptors V1A, V1B, and V2.[4]. Vasopressin-V1 binding is caused by decreased vessel tone, decreased vascular resistance and decreased blood pressure[1,2].

[Article in Russian] Artem'ev IIu, Darinskiĭ IuA, Sologub MI, Lozhkina TK. It is shown in this work that vasopressin at the concentrations of 1 x 10(-16) to 1 x 10(-6) or shock states, a relative deficiency of vasopressin has been found in prolonged vasodilatory shock, such as is seen in severe sepsis. In this circumstance, exogenous vasopressin has marked vasopressor effects, even at doses that would not affect blood pressure in healthy individuals. These two findings provide the rationale for the use of vasopressin in the treatment of septic shock.
