Chlorambucil
Chlorambucil is a chemotherapy drug used to treat cancer, including leukemia, lymphoma, and Hodgkins's lymphoma. It also can be used to treat certain autoimmune disorders and Crohn’s disease. As a chemotherapy drug, chlorambucil works by destroying cancer cells, stopping cancer cell growth, and keeping cancer from spreading. Chlorambucil belongs to a class of medications called alkylating agents.
Uses For
Chlorambucil is used to:
- Treat certain types of leukemia, lymphoma, and Hodgkin's lymphoma (HLA).
- Treat certain autoimmune disorders, such as rheumatoid arthritis or Crohn’s disease.

Mechanism Of Action
Chlorambucil works by crosslinking DNA strands in cancer cells to disrupt their replication and cell division processes. It is thought to work by inhibiting DNA and RNA synthesis and interrupting the process of cell replication, which eventually leads to cell death. It is also believed to work by influencing cell-signalling pathways.
