Abstract: Tolvaptan is a new type of non-peptide selective arginine vasopressin V2-receptor antagonist,which has the function of increasing renal solute-free water excretion and increasing serum sodium concentration. Due to the disorder of solute-free water excretion,decompensated cirrhotic patients are prone to hyponatremia. Application of tolvaptan in treatment of hyponatremia can effectively increase the concentration of sodium,reduce the risk of complications such as hepatic encephalopathy,hepatorenal syndrome,and refractory ascites. In this paper,we briefly summarized the mechanism of tolvaptan’s effects,the efficacy and safety in treatment of patients with hyponatremia.

Key words: Cirrhosis, Hyponatremia, Tolvaptan, Arginine vasopressin
