N-Acetylcysteine (NAC) is an active antioxidant proved to be safe and beneficial in hemodialysis patents [19]. In our recent study, NAC effectively reduced the ototoxic effect of gentamicin in chronic hemodialysis patients [20, 21]. Cheap and safe drug therapy may appear more cost effective than such resource consuming therapies as CPAP and not readily available treatments as prolong every night hemodialysis or kidney transplantation.
