Tolvaptan 15mg Tablet contains Tolvaptan, a selective vasopressin V2 receptor antagonist. It works by blocking the action of antidiuretic hormone (ADH) in the kidneys, leading to increased excretion of free water without significant loss of sodium or other electrolytes. Tolvaptan is primarily indicated for: Treatment of Hyponatremia (low sodium levels in blood) Syndrome of Inappropriate Antidiuretic Hormone (SIADH) Fluid retention associated with heart failure Slowing progression of kidney function decline in Autosomal Dominant Polycystic Kidney Disease (ADPKD) It helps correct sodium imbalance by promoting aquaresis (excretion of water without electrolyte loss). The 15mg strength is usually the starting dose and may be adjusted based on clinical response and serum sodium levels. This medication should be used under strict medical supervision due to the risk of rapid sodium correction and liver-related side effects.
