A small dose of Cyclophosphamide crated some side effects like low white blood cell counts, appetite, vomiting, hair loss, and bleeding from the bladder.
The molecular formula of Cyclophosphamide is C7H15Cl2N2O2P and the molecular structure is given above the picture. It was adopted in 1959 for use in medicine in the United States. World Health Organization’s listed it as an essential medicine for life. It is prepared by the interaction of bis (2-chloroethyl) phosphamide dichloride with propanolamine. Like other alkylating agents, it is a nitrogen mustard family of medications and works with the duplication of DNA and the creation of RNA.
Uses in Medicine
Cyclophosphamide is effective against acute leukemia, chronic lymphocytic leukemia, and multiple myeloma. In combination with other chemotherapy agents, it is found to cause a radial cure in acute lymphoblastic leukemia in children. It has a positive advantage over other alkylating agents because of its activity (parenterally and orally). It tolerant over a prolonged period in divided doses.

It used by different types of trade names like Lyophilized Cytoxan, Endoxan, Cytoxan, Neosar, Procytox, Revimmune, Cycloblastin. Different types of the dose of cyclophosphamide we used to treat different types of diseases.
|Therapy||Amount of dose||Period of dose|
|IV (intermittent therapy)||40-50 mg/kg or 400-1800 mg/m2||divided over 2-5 days|
|IV (continuous daily therapy)||60-120 mg/m2||per day|
|PO (intermittent therapy)||400-1000 mg/m2||divided over 4-5 days|
|PO (continuous daily therapy)||50-100 mg/m2 or 1-5 mg/kg||per day|
- For Nephrotic Syndrome, the doctor used 2-3 mg/kg/day for up to 12 weeks when corticosteroids unsuccessful.
- For Non-Hodgkin Lymphoma, the doctor used 600-1500 mg/m2 IV with other antineoplastics.
- For Breast Cancer, the doctor used 600 mg/m² IV with other antineoplastics.
- For Juvenile Idiopathic Arthritis/Vasculitis, the doctor used 10 mg/kg during the period of 2 weeks.
