Abstract
Elimination by hemofiltration of gentamicin, doxycyclin, ampicillin, sulfamethoxazole and clofibrate was measured in patients with chronic renal insufficiency. Clearance values of ampicillin and clofibrate were roughly in the range that might be expected according to the reported protein binding values of these drugs, whereas doxycyclin and sulfamethoxazole were eliminated to a much higher degree. Gentamicin clearances during a 6-hour hemofiltration treatment were lower than should be expected from reported protein binding values. For gentamicin and doxycyclin the filtered fraction linearly increased with time, a phenomenon which may be explained by membrane polarization.
