APPLICATIONS: It is generally supplied in prills or crystals/grains. We matched urea only-treated patients to a group of patients with hyponatremia who did not receive urea (urea untreated) and compared changes in plasma sodium at 24 hours and the end of therapy as well as the proportion of patients who achieved plasma sodium ≥135 mEq/L. We abstracted data on adverse events and reported side effects of urea.

The current proposal is a pilot study that seeks to establish the feasibility of recruiting ambulatory patients with chronic hyponatremia into a study of urea, determine the acceptability of urea to patients, and explore the effect of this agent on plasma sodium level (PNa), neurocognitive function, and postural stability.

The syndrome of inappropriate secretion of antidiuretic hormone (SIADH) is a condition characterized by hypotonic and euvolemic hyponatremia along with urinary hyperosmolarity, resulting from antidiuretic hormone (ADH) release in the absence of adequate stimuli. This term was first used in 1957, when Schwartz et al described hyponatremia caused.
