The clearance of rHuTNF after iv administration was determined to be saturable over the dose range of 10-63 micrograms/kg. Multiple iv administration did not significantly change the clearance of rHuTNF. Nephrectomy significantly reduced but did not eliminate the clearance of rHuTNF. The data suggest that sites other than the kidney also contribute to the elimination of rHuTNF. Female rats showed significantly reduced clearance of rHuTNF compared to male rats at all doses after single and multiple iv administration in control and nephrectomized animals.
