Clinical notes
Applications:
- Testicular cancer
Indication Notes:
Ifosfamide is indicated for use in combination with certain other approved antineoplastic agents for third-line chemotherapy of germ cell testicular cancer. It should be used in combination with Mesna for prophylaxis of hemorrhagic cystitis.
Avoid In:
N/A
Contraindication Notes:
Hypersensitivity; severe bone-marrow depression. Pregnancy, lactation.
Ifosfamide is converted to its active metabolites via hepatic microsomal enzymes. These active metabolites act as alkylating agents, disrupting DNA and protein synthesis of the target cells. It is routinely given with mesna to reduce urothelial toxicity.
Causes enhanced toxicity with allopurinol, cisplatin. Ifosfamide enhances the anticoagulant effect of warfarin. CYP2A6 inducers (e.g. amobarbital, pentobarbital, phenobarbital, rifampin and secobarbital) may reduce serum levels of ifosfamide while the inhibitors (e.g. isoniazid, methoxsalen and miconazole) may increase its serum levels. CYP3A4 inducers (e.g. aminoglutethimide, carbamazepine, nafcillin, nevirapine, phenobarbital, phenytoin, and rifamycins) may reduce serum levels of ifosfamide while the inhibitors (e.g. azole antifungals, clarithromycin, diclofenac, doxycycline, erythromycin, imatinib, isoniazid) may increase its serum levels.
Confusion, alopoecia, nausea, vomiting, phloebitis, somnolence, depression, hallucinations. Wound healing may be impaired during ifosfamide use.Potentially Fatal: Severe myelosuppression, haemorrhagic cystitis, nephrotoxicity, cardiotoxicity, coma.
Category D: There is positive evidence of human fetal risk, but the benefits from use in pregnant women may be acceptable despite the risk (e.g., if the drug is needed in a life-threatening situation or for a serious disease for which safer drugs cannot be used or are ineffective).
Hepatic or renal dysfunction, compromised bone marrow reserve. Use with mesna and ensure high oral/IV fluid intake to reduce urotoxic effects.
Renal Impairment: CrCl <10: Administer 75% of dose.
