1. pertaining to or causing suppression of urine production.
2. an agent that causes suppression of urine production.

antidiuretic hormone
vasopressin; a polypeptide hormine from the posterior lobe of the pituitary that suppresses the production of urine; it has a specific effect on the epithelial cells of the renal tubules, stimulating the reabsorption of water independently of solids, and resulting in concentration of urine. Stored and released by the posterior lobe of the pituitary gland, it also has vasopressor activity. Called also ADH.
antidiuretic hormone response test
measures urine specific gravity or osmolality before and after the administration of vasopressin to determine whether a polyuric condition is caused by a deficiency or reduced responsiveness to antidiuretic hormone. Called also Pitressin tannate test, Pitressin concentration test.
syndrome of inappropriate secretion of antidiuretic hormone (SIADH)
one in which there is abnormal production of ADH leading to hyponatremia (see also syndrome of inappropriate secretion of antidiuretic hormone).

The likely mechanism of hyponatremia is that quinolones cross the blood-brain barrier and stimulate the y-aminobutyric acid and N-methyl-D-aspartate receptors, which leads to the synthesis and release of antidiuretic hormone [8, 9].

He cautions, however, that the medication--an antidiuretic hormone (Vasopressin)--also can cause insufficient urine production, which can upset the patient's serum electrolyte balance.
18) The onset of NED may be immediate (eg, in diabetes insipidus [DI] or syndrome of inappropriate antidiuretic hormone [SIADH], which are very rare in mTBI) and potentially life-threatening (eg, in sodium and potassium imbalances), or may be nonspecific and take years to manifest.
10) found that antidiuretic hormone release induced hyponatermia may originate in a nonosmotic, cardiovascular mechanism in acutely ill children, including children with pneumonia.
The neuropeptides, which include antidiuretic hormone and oxytocin, travel down the long axons of the cells and are released from the posterior pituitary gland.
Causes of hyponatremia include extrarenal sodium loss in diarrhea, vomiting, pancreatitis, renal loss induced by diuretics, Addison disease, salt-wasting nephropathy, an increased volume of extracellular fluid in congestive heart failure, cirrhosis, nephrotic syndrome, acute or chronic renal failure, syndrome of inappropriate secretion of antidiuretic hormone (SIADH), [2] hypothyroidism, and excess water intake, a relatively uncommon cause (1).
