Cytoxan

Cytoxan is a chemotherapy medication that is used for treating nephrotic syndrome in children and various types of cancer in adults. Leukemia, breast cancer, and multiple myeloma are among the types of cancer that Cytoxan may be used to treat. Cytoxan, which is available by prescription, comes as an injection and in tablet form. Side effects of Cytoxan can include loss of appetite, hair loss, mouth sores, and diarrhea.

How Does Cytoxan Work?

Cytoxan is part of a group of medications called alkylating agents. Cytoxan itself is not active against cancer, but it is metabolized by the liver into its active form. The active form causes "cross-linking" of DNA cells. When DNA is cross-linked, it can no longer function properly. Since DNA is essential for cells to grow and multiply, alkylating medications prevent cell growth and multiplication and may cause cell death.
 
While Cytoxan can kill both healthy and cancerous cells, it has a greater effect on cells that are multiplying rapidly. Generally, cancer cells multiply more rapidly than healthy cells and are, therefore, more affected by Cytoxan.
 
Cytoxan also suppresses the immune system, which is probably how it works to treat nephrotic syndrome.
