N2 - The prevalence and incidence of congestive heart failure continues to increase. The two hallmarks of this syndrome, sodium and water retention, are frequently a therapeutic challenge. Most conventional diuretics act primarily as saluretics by inhibiting renal tubular electrolyte reabsorption, which, due to osmotic pressure, promotes excretion of isotonic fluid. The peptide hormone arginine vasopressin vasoconstricts at the V1A receptor and promotes water reabsorption via the V2 receptor in the renal collecting duct by inserting aquaporin-2 water channels into the luminal membrane. Tolvaptan, the first orally available non-pepticle V2 receptor antagonist, acts as a potent aquaretic. In this paper, the authors review the pharmacology of tolvaptan and discuss the results of the initial clinical trials with this potent new drug.
