Chlorambucil (marketed as Leukeran by GlaxoSmithKline) is a chemotherapy drug that has been mainly used in the treatment of chronic lymphocytic leukemia. It is a nitrogen mustard alkylating agent[1] and can be given orally.

It is on the World Health Organization's List of Essential Medicines, a list of the most important medication needed in a basic health system.[2]

Medical uses[edit]

Chlorambucil's current use is mainly in chronic lymphocytic leukemia, as it is well tolerated by most patients, though chlorambucil has been largely replaced by fludarabine as first-line treatment in younger patients.[3] It can be used for treating some types of non-Hodgkin lymphoma, Waldenström macroglobulinemia, polycythemia vera, trophoblastic neoplasms, and ovarian carcinoma. Moreover, it also has been used as an immunosuppressive drug for various autoimmune and inflammatory conditions, such as nephrotic syndrome.

Side effects[edit]

Bone marrow suppression (anemia, neutropenia, thrombocytopenia) is the most commonly occurring side effect of chlorambucil. Withdrawn from the drug, this side effect is typically reversible. Like many alkylating agents, chlorambucil has been associated with the development of other forms of cancer.

Less commonly occurring side effects include:
