Tolvaptan 15mg is an oral vasopressin V2-receptor antagonist containing Tolvaptan as the active ingredient. It is primarily indicated for the treatment of clinically significant hyponatremia (low sodium levels in blood), especially in conditions such as SIADH (Syndrome of Inappropriate Antidiuretic Hormone Secretion), heart failure, and liver cirrhosis. Tolvaptan works by selectively blocking vasopressin receptors in the kidneys, leading to increased free water excretion without significant loss of electrolytes. This process helps correct sodium imbalance safely and effectively. It is also used in selected cases of autosomal dominant polycystic kidney disease (ADPKD) under specialist supervision. Tolvaptan 15mg tablets are administered under strict medical supervision due to the need for sodium monitoring and liver function assessment during therapy.
