Effects of different dialysis membranes on serum concentrations of epoetin alfa, darbepoetin alfa, enoxaparin, and iron sucrose during dialysis.

Background: Numerous substances are administered during dialysis for anticoagulation and the treatment of anemia and iron deficiency. The availability of current dialysis membranes is diverse, but assessment of the effects of different membranes on these routinely administered substances is lacking. This prospective study appraises specific effects of 7 dialysis membranes (4 low-flux membranes, 3 high-flux membranes) on the handling of 4 commonly administered agents (epoetin alfa, darbepoetin alfa, enoxaparin, and iron sucrose) during dialysis.
