Clinical evaluation of two daily doses of naproxen and indomethacin: result of a double-blind crossover trail.

ABSTRACT

A double-blind crossover clinical trial is reported on the effects of naproxen in two doses, 500 mg. and 750 mg. daily, and 100 mg. indomethacin daily in 23 patients with classical rheumatoid arthritis, each drug being given for 1 week. The results show that there was little to choose between the drugs and that there was clinical equivalence between the two doses of naproxen. Radioactive pertechnetate (99mTc) joint uptakes were depressed by both naproxen and indomethacin, indicating anti-inflammatory effect.
