[Naproxen versus indomethacin as night-time medication for patients with rheumatoid arthritis]

The investigation consisted of a double-blind cross-over study of the effect of 75 mg indometacin, 500 mg naproxen or a placebo in 63 patients with rheumatoid arthritis accompanied by night pain and morning stiffness. All the patients received day treatment with 250 mg naproxen b.i.d. Only a few patients benefitted from the treatment at night and no differences in the effect of indometacin and naproxen were observed. Naproxen was better tolerated than indometacin. Day treatment with naproxen, which has a relatively long half life time decrease the need for supplementary treatment at night.
