Thiotepa is an alkylating agent of the ethyleneimine type, used primarily as an antineoplastic chemotherapy drug. It has been indicated for use in the treatment of various cancers including breast cancer, ovarian cancer, and bladder cancer. Thiotepa is approved for use as a conditioning treatment prior to hematopoietic stem cell transplantation and for high-dose chemotherapy settings.
Pharmacokinetics
Pharmacokinetic parameters reported for adult cancer patients receiving intravenous thiotepa as part of high-dose chemotherapy for stem cell transplantation.
