What Is Methotrexate?
Methotrexate is a chemotherapy and immunosuppressant drug commonly used in cancer therapy. It belongs to a class of medications called antimetabolites, which interfere with DNA synthesis and cell replication.
How Methotrexate Works in Cancer Treatment
Methotrexate works by targeting rapidly dividing cells, which is a hallmark of cancer. It inhibits an enzyme called dihydrofolate reductase, preventing cancer cells from producing DNA and proteins necessary for growth.
Key Actions:
Stops cancer cell growth
Slows tumor progression
Enhances effectiveness of combination chemotherapy
