Ifosfamide enantiomers: pharmacokinetics in children.

Journal Article (Journal Article)

Ifosfamide, like other oxazaphosphorine drugs, is chiral and there is some evidence, mainly from animal studies, of stereo-selective differences in metabolism, excretion and cytotoxic activity between the two enantiomers. The pharmacokinetics of racemic ifosfamide (RAC-IFO), R-ifosfamide (R-IFO) and S-ifosfamide (S-IFO) were studied in five children who received intravenous therapy with racemic ifosfamide on 3 consecutive days. The clearance of S-IFO was greater than that of R-IFO. The clearance value at the end of the infusion was faster than the respective rate measured at the beginning of or during the ifosfamide regimens in four children and, therefore, suggests autoinduction of elimination of both enantiomers.
