Efficacy of tolvaptan

Tolvaptan has demonstrated significant efficacy in the treatment of hyponatremia and fluid retention caused by heart failure. By antagonizing vasopressin V2 receptors, it improves free water clearance and urinary excretion, thereby effectively increasing serum sodium concentration and reducing body fluid retention.

Efficacy of Hyponatremia

Clinical trials have shown that tolvaptan can significantly increase the serum sodium concentration and improve related symptoms in patients with hyponatremia. Patients in the tolvaptan group experienced more significant increases in serum sodium concentrations and fewer patients required fluid restriction compared with placebo. In addition, tolvaptan can effectively maintain the patient's fluid balance and reduce the risk of recurrence of hyponatremia.

Efficacy in heart failure

Tolvaptan also shows good efficacy in treating fluid retention caused by heart failure. Clinical trial results show that tolvaptan can significantly reduce patients' weight and fluid retention, and improve related symptoms such as jugular venous distention, hepatomegaly, and lower limb edema.

In addition, tolvaptan can also increase the patient's urine output and promote the excretion of excess fluid in the body.
