Rheumatoid arthritis: a pharmacologic overview.

Numerous drugs are available for the treatment of rheumatoid arthritis. The nonsteroidal anti-inflammatory drugs differ in structure and pharmacokinetics, and they rarely act synergistically. The disease-modifying antirheumatic drugs include gold compounds, penicillamine, hydroxychloroquine and sulfasalazine. Useful immunosuppressive and cytotoxic agents include methotrexate, azathioprine and cyclophosphamide. Costicosteroids find their greatest use in short courses.
