|Description||OPC 31260 is a Vasopressin receptor antagonist marketed by Otsuka. It is a benzazepine derivative that antagonizes the binding of arginine vasopressin (AVP) to vasopressin receptors located in the liver (V1; IC50 = 1.2 µM) and kidney (V2; IC50 = 14 nM). In Japan, OPC 31260 was approved in October 2006 for hyponatremia (low blood sodium levels) caused by syndrome of inappropriate antidiuretic hormone (SIADH) due to ADH producing tumors.|
