Tolvaptan has been used as a V2-selective antagonist for studying its effect on hypertension in mice.


5, 25 mg in glass bottle

Biochem/physiol Actions

Tolvaptan (OPC 41061) is a potent, orally active non-peptide vasopressin V2 selective antagonist. IC50 = 3 nM at the rat V2 receptor; 29 times more selective for the V2 than for V1a. Tolvaptan has also been shown to inhibit the development of polycystic kidney disease in several animal models.
