instructions for use

Vasopressin, or Antidiuretic Hormone (ADH) is a cyclic nanopeptide with a molecular weight of 1083. Its structure is very similar to that of oxytocin, differing in only two amino acids. Endogenous ADH has antidiuretic and pressor activity, both approaching 400 units per mg, with an antidiuretic-to-vasopressin ratio of 1, and a biphasic plasma half-life of 2.5 and 14.5 minutes. ADH is synthesized in the hypothalamic supraoptic nucleus and paraventricular nucleus of primates and transported via exonal flow to the posterior pituitary for storage and eventual release. The clinical application of a vasopressin radioimmunoassay is in diabetes insipidus, psychogenic water intoxication, hyponatraemia, stress conditions, ADH as a neurotransmitter and hypertension studies. ADH values can be influenced by cigarettes, tea, coffee, alcohol and some drugs.
