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).
