Pharmacology
Tolvaptan is a selective vasopressin V2-receptor antagonist that blocks vasopressin's renal effect, promoting free water excretion (aquaresis) and raising serum sodium concentrations without significantly affecting urinary sodium or potassium excretion.
ACE inhibitor; enalapril is hydrolyzed to enalaprilat, which inhibits angiotensin-converting enzyme, suppressing the renin-angiotensin-aldosterone system and thereby reducing plasma angiotensin II, vasopressor activity, and aldosterone secretion.
