Chlorambucil

[3] Other serious side effects include an increased long term risk of further cancer, infertility, and allergic reactions.

[6] It can be used for treating some types of non-Hodgkin lymphoma, Waldenström macroglobulinemia, polycythemia vera, trophoblastic neoplasms, and ovarian carcinoma.

Bone marrow suppression (anemia, neutropenia, thrombocytopenia) is the most commonly occurring side effect of chlorambucil.

A recent study has shown Chlorambucil to be detoxified by human glutathione transferase Pi (GST P1-1), an enzyme that is often found over-expressed in cancer tissues.

[13] This is important since Chlorambucil, as an electrophile, is made less reactive by conjugation with glutathione, thereby making the drug less toxic to the cell.

When heated to decomposition it emits very toxic fumes of hydrogen chloride and nitrogen oxides[12] Nitrogen mustards arose from the derivatization of sulphur mustard gas after military personnel exposed to it during World War I were observed to have decreased white blood cell counts.
