Efficacy and tolerance of naproxen versus pirprofen in the treatment of patients with osteoarthritis.

A double-blind, double-dummy study design was used to compare the efficacy and tolerance of naproxen with that of pirprofen in the treatment of osteoarthritis. Sixty patients were assigned randomly to receive either 500 mg naproxen twice daily or 400 mg pirprofen twice daily for 4 weeks. Both groups were similar in all respects except age, which was significantly greater in the naproxen-treated patients than in the pirprofen-treated patients.

Meclofenamate sodium in the treatment of ankylosing spondylitis. Report of a European double-blind controlled multicenter study.

98 patients with reversible, definite, active ankylosing spondylitis were selected for this study. 49 patients were treated with N-(2,6-dichloro-m-tolyl)anthranilic acid, sodium salt (meclofenamate sodium, Meclomen) and 49 patients with indometacin. Following a single-blind baseline period on placebo, patients received either 200 mg meclofenamate sodium per day or 100 mg indometacin per day for one week, in the second week the doses were increased to 250 mg meclofenamate sodium and 125 mg indometacin and from the third through the eight week 300 mg meclofenamate sodium and 150 mg indometacin were given.

Double-blind multicenter study comparing meclofenamate sodium with indomethacin and placebo in the treatment of extra-articular rheumatic disease.

161 patients with extra-articular or non-articular disorders as acute shoulder syndrome, periarthritis humero scapularis, syndrome of the angular of the scapula, acute olecranon bursitis, acute epicondylitis and/or epitrochleitis or periarthritis of the hip were treated in this double-blind multicenter study. 53 patients received 300 mg N-(2,6-dichloro-m-tolyl)anthranilic acid, sodium salt (meclofenamate sodium, Meclomen) per day for a maximum of 3 weeks, 54 received 150 mg indomethacin per day and 54 received placebo. Meclofenamate sodium was significantly superior to placebo in the treatment of such symptoms as spontaneous pain, pain on motion, tenderness on pressure associated with acute episodes of extra- or non-articular rheumatism as demonstrated by earlier and superior improvement.

A double-blind study of erbium169 synoviorthesis in rheumatoid digital joints. Results after one year.

A double-blind study was made on the effectivenss of erbium169 synoviorthesis in the digital joints of 7 patients with erosive, seropositive rheumatoid arthritis. The study involved 70 joints observed over a 12-month period: 20 pairs of metacarpophalangeal joints (MCP) and 15 pairs of proximal interphalangeal joints (PIP) were injected with erbium169 in one joint and saline in the other one. All joints had radiological lesions corresponding to State I and II of the Steinbroker classification.
