Cyfos
Cyfos - General Information
Positional isomer of cyclophosphamide which is active as an alkylating agent and an immunosuppressive agent. [PubChem]
Pharmacology of Cyfos
Cyfos selectively inhibits the synthesis of deoxyribonucleic acid (DNA). The guanine and cytosine content correlates with the degree of ifosfamide-induced cross-linking. At high concentrations of the drug, cellular RNA and protein synthesis are also suppressed.
Cyfos for patients
Cyfos Interactions
The physician should be alert for possible combined drug actions, desirable or undesirable, involving ifosfamide even though ifosfamide has been used successfully concurrently with other drugs, including other cytotoxic drugs.
Cyfos Contraindications
Continued use of IFEX is contraindicated in patients with severely depressed bone marrow function. IFEX is also contraindicated in patients who have demonstrated a previous hypersensitivity to it.
Additional information about Cyfos
Cyfos Indication: For third line chemotherapy of germ cell testicular cancer. It should ordinarily be used in combination with a prophylactic agent for hemorrhagic cystitis, such as mesna.
Mechanism Of Action: After metabolic activation, active metabolites of ifosfamide alkylate or bind with many intracellular molecular structures, including nucleic acids. The cytotoxic action is primarily due to cross-linking of strands of DNA and RNA, as well as inhibition of protein synthesis.
