methotrexate

methotrexate
n.
a drug that interferes with cell growth and is used to treat many types of cancer, including leukaemia in children and various solid tumours (see antimetabolite, dihydrofolate reductase inhibitor). It also affects the immune response and may be used in the treatment of rheumatoid arthritis and severe psoriasis (see disease-modifying antirheumatic drug). Methotrexate is administered by mouth or injection; common side-effects include mouth sores, digestive upsets, skin rashes, and hair loss.
