Definition
A very toxic alkylating antineoplastic agent also used as an insect sterilant. It causes skin, gastrointestinal, CNS, and bone marrow damage. According to the Fourth Annual Report on Carcinogens (NTP 85-002, 1985), thiotepa may reasonably be anticipated to be a carcinogen (Merck Index, 11th ed).
Description

General Information
- Metabolism: Route of Elimination: Urinary excretion of 14C-labeled thiotepa and metabolites in a 34-year old patient with metastatic carcinoma of the cecum who received a dose of 0.3 mg/kg intravenously was 63%. Half Life: 1.5 to 4.1 hours
- Uses/Sources: ThioTEPA is used a as conditioning treatment prior to allogeneic or autologous haematopoietic progenitor cell transplantation (HPCT) in haematological diseases in adult and paediatric patients. Also, when high dose chemotherapy with HPCT support it is appropriate for the treatment of solid tumours in adult and paediatric patients.
