Enhanced clearance of highly protein-bound drugs by albumin-supplemented dialysate during modeled continuous hemodialysis

摘要

Background. In 2006, there were 16 796 toxic exposures attributed to valproic acid (VPA), carbamazepine (CBZ) and phenytoin (PHT) reported to the US Toxic Exposure Surveillance System. Of these, 30% (5046) were treated in a health care facility with 12 cases resulting in death. These drugs are highly protein bound and poorly dialyzable; however, it has been suggested that albumin-supplemented dialysate may enhance dialytic clearance. We investigated whether the addition of albumin to dialysate affects dialytic clearance of VPA, CBZ and PHT.
