Vasopressin may preferentially cause vasoconstriction of post-glomerular arterioles in the kidney, causing improvement in renal function. It may cause some pulmonary vasodilation, which can be helpful in the context of pulmonary hypertension. Vasopressin shouldn't generally be given peripherally (if it extravasates, there is no antidote). 2020-01-22 Vasopressin levels ≥ 20 pg.ml −1 cause maximal increase in urine osmolality. The half‐life of vasopressin is 10–35 min.
This precursor circulates along axons of magnocellular neurons, through the pituitary stalk, to the post-pituitary gland. Vasopressin is stored in the post-pituitary gland, mostly in the intracellular compartment. Vasopressin levels ≥ 20 pg.ml −1 cause maximal increase in urine osmolality. The half‐life of vasopressin is 10–35 min. It is rapidly metabolised by liver and kidney vasopressinases .
Se hela listan på academic.oup.com Vasopressin has gained wide support as an adjunct vasopressor in patients with septic shock. This agent exerts its vasoconstriction effects through smooth muscle V 1 receptors and also has antidiuretic activity via renal V 2 receptors.

1,2,5 It is also Summary: There is growing evidence that vasopressin infusion in septic shock is safe and effective. Several studies published this year support the hypothesis that vasopressin should be used as a continuous low-dose infusion (between 0.01 and 0.04 U/min in adults) and not titrated as a single vasopressor agent. So, normally, we all have vasopressin or anti-diuretic hormone present in our body but the level is not that high that it will cause vasoconstriction. But let’s say if someone having a low blood pressure then you would put them on vasopressin drips.
It is antidiuretic hormone (ADH), which is a vasoconstrictor without the inotopic or chronotropic effects. It acts on the kidneys and blood vessels and retains fluid within the body. By increasing the fluid retained, this subsequently increases the patient’s blood pressure.
