Abstract
Purpose
The pharmacokinetics of etoposide were studied in cancer patients with brain metastases treated with high-dose etoposide in order to determine if the pharmacokinetics were altered by the use of dexrazoxane as a rescue agent to reduce the extracerebral toxicity of etoposide.
Methods
Etoposide plasma levels were determined by HPLC.
Results
The etoposide pharmacokinetics described by a monophasic first-order elimination model were found to be similar to other reported data in other settings and at similar doses.
Conclusions
The pharmacokinetics of etoposide were unaffected by dexrazoxane rescue.
