Piroxicam in juvenile rheumatoid arthritis.

There is little consistency in drug treatment of children with juvenile rheumatoid arthritis, in part because there are few controlled studies of the use of nonsteroidal anti-inflammatory drugs (NSAIDs) in this disease. To determine the safety and efficacy of piroxicam in children with juvenile rheumatoid arthritis, 26 patients ranging in age from three to 25 years were randomly assigned to treatment with piroxicam or naproxen. The number of painful and swollen joints decreased significantly (p less than 0.05) in the piroxicam group. The overall assessment of the investigators was that 67% of the patients in the piroxicam group showed clinical improvement, in contrast to 38% of the naproxen-treated patients. Side effects in the piroxicam group were mild and transient, and no patient was removed from the study because of side effects. The recurrence of a cutaneous rash necessitated the removal of one naproxen-treated patient from the study. Although the results should be interpreted with caution because of the small sample size, piroxicam appears to be more effective and better tolerated than naproxen in this study.
