The drug methotrexate belongs to the group of drugs known as antimetabolites. By reducing the growth of cancer cells, methotrexate treats cancer. In order to prevent the development of scales, methotrexate slows the growth of skin cells in psoriasis. Methotrexate may treat rheumatoid arthritis by reducing immune system activation.
Methotrexate obstructs the creation of DNA. This prevents cell division and growth, which slows or stops the growth of cancer. Cancer cells are more vulnerable to this harm because they divide more quickly and with less error-correcting than healthy cells do.
Acute lymphoblastic leukaemia (ALL), especially ALL that has progressed to the central nervous system, can be treated with methotrexate sodium alone or in combination with other medications.
