ABSTRACT
A series of double-blind, parallel, clinical trials was carried out to assess the analgesic and anti-inflammatory effects of tenoxicam and to compare the efficacy and tolerance of this compound with those of piroxicam in patients suffering from osteoarthrosis, rheumatoid arthritis and ankylosing spondylitis. In equivalent once-daily dosage (20 mg), tenoxicam was found to be at least as effective as piroxicam in combating the symptoms of the above arthritic disorders and, even in relatively high dosages of 30 and 40 mg exhibited excellent tolerance, producing fewer adverse reactions than piroxicam. It is concluded that tenoxicam represents a valuable addition to the spectrum of anti-inflammatory agents.

Piroxicam and diclofenac were compared for 4 weeks in an open parallel study in 20 rheumatoid arthritis patients each. Both preparations showed good efficacy and were well tolerated, piroxicam appearing to be slightly superior in both respects. Piroxicam exercised a significant action on the inflammation-specific parameters (reduction of BSR by 6.15 mm maximum and of the alpha 2-globulin fraction by 0.75%), whereas diclofenac did not. Another advantage of piroxicam is its low effective dosage level achieved by a single daily dose.
