Conivaptan (vaprisol®, YM 087) is a non-peptide inhibitor of antidiuretic hormone (vasopressin). It was approved in 2004 for hyponatremia (low blood sodium levels) caused by syndrome of inappropriate antidiuretic hormone (SIADH), and there is some evidence it may be effective in heart failure. It is marketed by Astellas Pharma Inc.

Conivaptan inhibits both isotypes of the vasopressin receptor (V1a and V2). Effectively, it causes iatrogenic nephrogenic diabetes insipidus.
