Such precise control of body water and solute concentrations is a function of several hormones acting on both the kidneys and vascular system, but there is no doubt that antidiuretic hormone is a key player in this process. Antidiuretic hormone, also known commonly as arginine vasopressin , is a nine amino acid peptide secreted from the posterior pituitary. Within hypothalamic neurons, the hormone is packaged in secretory vesicles with a carrier protein called neurophysin, and both are released upon hormone secretion. The single most important effect of antidiuretic hormone is to conserve body water by reducing the loss of water in urine. A diuretic is an agent that increases the rate of urine formation. Injection of small amounts of antidiuretic hormone into a person or animal results in antidiuresis or decreased formation of urine, and the hormone was named for this effect.
Inappropriate antidiuretic hormone secretion-in premature newborn.
ADH: Antidiuretic Hormone - Assignment Point
It is one of only two hormones secreted by the posterior pituitary gland. In this article, we will discuss the synthesis, storage, release and action of ADH, and consider its clinical relevance. The synthesis of ADH occurs in the supraoptic and paraventricular nuclei in the hypothalamus. It is then transported to the posterior pituitary gland via the neurohypophysial capillaries.

There are several categories of diuretics. All diuretics increase the excretion of water from bodies, although each class does so in a distinct way.
