Disposition of ifosfamide in patients receiving ifosfamide infusion therapy for the treatment of cervical carcinoma.

The disposition of ifosfamide was investigated in nine patients receiving a total of 23 72-h infusions. There was no linear relationship between steady-state plasma concentrations and either vomiting or CNS toxicity. The steady-state plasma concentrations were reproducible within patients, but there was a wide variation between patients. The progress of the disease did not affect the disposition of ifosfamide.
