Tolvaptan
Tolvaptan is a selective vasopressin V2 receptor antagonist (vaptans class) that blocks the antidiuretic action of arginine vasopressin (AVP) in the renal collecting duct, preventing water reabsorption and promoting free water excretion (aquaresis) without significant sodium or potassium loss. It is approved for hyponatremia in syndrome of inappropriate ADH secretion (SIADH), congestive heart failure, and cirrhosis, and for slowing kidney cyst growth in autosomal dominant polycystic kidney disease (ADPKD). Its aquaretic mechanism corrects hyponatremia and reduces cyst expansion without the electrolyte disturbances of conventional diuretics.
