What is Tolvaptan?
Tolvaptan is a selective vasopressin V2-receptor antagonist. It is primarily used to treat:
- Hyponatremia (low blood sodium levels), especially associated with conditions like heart failure and syndrome of inappropriate antidiuretic hormone (SIADH).
- Autosomal Dominant Polycystic Kidney Disease (ADPKD) – a genetic disorder causing kidney cysts and gradual renal failure.
The drug helps restore sodium balance and slow the progression of kidney damage by reducing fluid accumulation.
Mechanism of Action
Tolvaptan works by blocking the vasopressin V2 receptors in the kidneys. Vasopressin is a hormone that promotes water reabsorption. By blocking its action, Tolvaptan allows the kidneys to excrete excess water without losing essential electrolytes like sodium. This process, known as aquaretic effect, helps correct hyponatremia and manage fluid overload.
In ADPKD, Tolvaptan reduces the rate of cyst growth and kidney enlargement, effectively slowing disease progression.
Medical Uses of Tolvaptan

- Cirrhosis of the liver
2. ADPKD (Autosomal Dominant Polycystic Kidney Disease)
Tolvaptan is the first FDA-approved treatment for ADPKD, shown to:
- Slow kidney volume growth
- Delay the decline in kidney function
- Improve quality of life for ADPKD patients
Benefits of Tolvaptan
- Improves sodium levels safely without causing significant fluid loss
- Slows kidney function decline in ADPKD patients
- Reduces hospitalization in patients with chronic heart failure
