Tolvaptan

Tolvaptan is a vasopressin receptor antagonist used to treat low sodium levels in the blood (hyponatremia) and autosomal dominant polycystic kidney disease (ADPKD). It helps balance water levels in the body by promoting urine production and preventing excessive water retention. Tolvaptan is typically prescribed for patients with conditions like heart failure, liver disease, or kidney disorders that cause fluid imbalances. By increasing sodium levels, it helps improve symptoms like confusion, weakness, and swelling. It is available in tablet form and should be used under medical supervision to monitor kidney function and electrolyte levels.

Uses of Tolvaptan

  • Treatment of low sodium levels (hyponatremia)
  • Management of autosomal dominant polycystic kidney disease (ADPKD)
  • Helps control fluid balance in heart failure
  • Used in liver cirrhosis with fluid overload
  • Prevents excessive water retention in the body

How Tolvaptan Works

Tolvaptan works by blocking vasopressin, a hormone responsible for water retention in the kidneys. This increases urine production and helps the body eliminate excess fluid, thereby raising sodium levels in the blood. It also slows the growth of kidney cysts in patients with ADPKD, preserving kidney function over time.
