Information about Ifosfamide
Ifosfamide is a parenterally administered alkylating agent similar to cyclophosphamide that is used in the treatment of several forms of cancer including lymphomas, sarcoma and advanced forms of solid organ cancer such as breast, testicular, ovarian, gastric and lung cancer. Ifosfamide therapy is associated with minor transient serum enzyme elevations and has been linked to cases of acute liver injury, including acute cholestatic hepatitis and veno-occlusive disease.
Mechanism of action of Ifosfamide
Ifosfamide (eye fos' fa mide) is an analogue of cyclophosphamide and thus a nitrogen mustard-like alkylating agent that is used in the therapy of several forms of leukemia, lymphoma and solid organ cancer. Like cyclophosphamide, ifosfamide requires activation in the liver to form its active intermediaries which act by modifying and cross linking purine bases in DNA, thus inhibiting DNA, RNA and protein synthesis and leading to programmed cell death (apoptosis) in rapidly dividing cells.
FDA approval information for Ifosfamide
Ifosfamide was approved for use in the United States in 1988 and its major indication is for germ cell testicular cancer, but it is also used in combination with other agents in the treatment of breast, lung, bladder, cervical, and ovarian cancer, Hodgkin's and non-Hodgkin’s lymphoma, and soft tissue and osteogenic sarcomas. Ifosfamide is given intravenously and is available in liquid formulations (1 and 3 gram vials), generically and under the trade name Ifex.
Dosage and administration for Ifosfamide
Recommended doses vary by body weight and malignant condition.
Side effects of Ifosfamide
- Common side effects include alopecia, nausea, vomiting, diarrhea, gastrointestinal upset, cystitis, oral ulcers and bone marrow suppression. It is commonly given with mesna to reduce the risk of hemorrhagic cystitis.
