The P-glycoprotein á Intestinal elimination plasma area under the curve (AUC) of conjugated etoposide represented 12% of the total (conjugated plus unchanged etoposide) AUC. Table 1 shows the per- centages of the delivered dose recovered in bile and urine. The observed clearance of this patient coincides with the mean value previously reported (30.2 ml/min [2]). Numerous pharmacokinetics studies of etoposide have The plasma unbound fraction was twice that of the been performed during the last decade (see Joel [1] for review). However, the respective parts played by me- mean value observed in cancer patients (8.4% [2]). This was due more likely to her low plasma albumin level tabolism and biliary secretion in the nonrenal elimina- (i.e., 27 g/l) than to the high bilirubin level, since the tion pathways are not yet clear.
