A double-blind cross-over evaluation of ketoprofen and aspirin in rheumatoid arthritis.

Thirty rheumatoid patients participated in a 6-week double-blind cross-over assessment of ketoprofen (200 mg daily) and aspirin (3.6 g daily). Regular clinical and laboratory assessments were conducted and revealed that at the dosages employed, the two drugs exerted a statistically comparable therapeutic effect. Side-effects were more frequent with aspirin. Ketoprofen was preferred more often by the patients while the investigator found it acceptable as often as aspirin.
