Vasopressin antagonists effective in treating hyponatremia

This meta-analysis found vasopressin receptor antagonists are effective at raising serum sodium levels in patients with euvolemic and hypervolemic hyponatremia. Normalization of serum sodium occurred significantly earlier with these agents than without, and were more effective in euvolemic than hypervolemic patients. There was also no increase risk of adverse events or hypernatremia, and no reported demyelination syndromes. Although these agents seem to be still finding their role in clinical medicine, they do appear to be safe and moderately effective based on this meta-analysis (abstract)
