Biochem/physiol Actions

OPC-21268 is a vasopressin V1a selective antagonist.
OPC-21268 is one of 2 non-peptide V1a selective antagonists, along with SR-49059. Arginine vasopressin (AVP) is a hormone that plays an important part in circulatory and water homoeostasis and is important in renal hemodynamic alterations, water retention, and cardiac remodeling in congestive heart failure (CHF). There are three AVP receptor subtypes-V1a, V1b, and V2 - all belong to the large rhodopsin-like G-protein-coupled receptor family. V(1a) antagonists improve water balance and cardiac hypertrophy in CHF and might be beneficial for the treatment of water retention and cardiac remodeling in CHF.
