[Comparative study of piroxicam and indomethacin retard in arthroses].

Indomethacin retard and piroxicam (Felden) were compared in an open, randomized parallel study in the treatment of osteoarthritis. Improvement of the symptoms of the disease was highly significant for both drugs. A statistical difference in the efficacy was not proved. Number and duration of the side effects were significantly lower with piroxicam than with indomethacin retard. Piroxicam was only applied once a day. Indomethacin retard was always (43% of the cases) or sometimes (14%) applied twice daily.
