Arginine vasopressin (AVP), also known as argipressin or antidiuretic hormone (ADH), is a human hormonethat is released when the body is low on water; it causes the kidneysto conserve water, but not salt, by concentrating the urineand reducing urine volume. It also raises blood pressure by inducing moderate vasoconstriction. It has various effects in the brain.A very similar substance, lysine vasopressin (LVP) or lypressin, has the same function in pigsand is often used in human therapy.Vasopressin is a peptide hormone. It is derived from a preprohormoneprecursor that is synthesized in the hypothalamus, from which it is liberated during transport to the posterior pituitary. Most of it is stored in the posterior partof the pituitary glandto be released into the blood stream; some of it is also released directly into the brain.AVP allows water reabsorption by the introduction of additional water channels in cortical and inner medullary collecting ducts.
