Rofecoxib for rheumatoid arthritis.

Editor's note: The anti-inflammatory drug rofecoxib (Vioxx) was withdrawn from the market at the end of September 2004 after it was shown that long-term use (greater than 18 months) could increase the risk of heart attack and stroke. Further information is available at www.vioxx.com. Rheumatoid arthritis (RA) is a systemic auto-immune disorder, in which the synovial lining of many joints and tendon sheaths are persistently inflamed.
