Drug Mode of Action ::  

Cyclophosphamide is a prodrug which is converted in the body to the active metabolites. It acts at any stage of the cell cycle but its main action is blockage at the G2 stage. It arrests cell division by alkylating the DNA in a dose-dependent manner. It also exerts immunosuppressive effects possibly due to a cytotoxic effect on lymphocytes.

Drug Interactions ::

Chronic high-dose administration of phenobarbital can increase the metabolism and leukopaenic activity of cyclophosphamide. Doxorubicin and daunorubicin increase risk of cardiotoxicity. Allopurinol may increase risk of bone marrow toxicity while chloramphenicol may increase the serum T1/2 of cyclophosphamide. Potentially Fatal: Serious toxicity when combined with other myelotoxic drugs or radiotherapy.
