Methotrexate in the treatment of rheumatoid arthritis

Methotrexate is an effective agent for the treatment of rheumatoid arthritis. It is now widely prescribed for patients who have not tolerated or responded to gold compounds or penicillamine. Minor adverse reactions are common, and fatal pulmonary toxicity or cirrhosis can occur. The drug does not produce disease remissions, but continued administration helps reduce pain, stiffness and swelling. Within the past year, the Food and Drug Administration has approved methotrexate for use in treating rheumatoid arthritis.
