Proquazone is a non-steroidal anti-inflammatory agent (NSAID) which, unlike most other NSAIDs, does not have a free acid group in its structure. It is advocated for use in rheumatoid arthritis, ankylosing spondylitis, osteoarthritis, musculoskeletal disorders, acute inflammatory conditions and acute pain states such as dysmenorrhoea, postoperative pain and headache. Published data in small groups of patients indicate that proquazone 300 to 900 mg/day in 3 divided doses is a possible alternative to aspirin, ibuprofen, indomethacin, and naproxen in rheumatoid arthritis, and to indomethacin and ibuprofen in ankylosing spondylitis. Similarly, proquazone 300 to 900 mg/day is as effective as aspirin, diclofenac, ibuprofen, indomethacin and naproxen in patients with osteoarthritis. Preliminary studies have confirmed the efficacy of proquazone in acute inflammatory disorders, and shown that it provides useful analgesic relief in acute pain states such as dysmenorrhoea, headache and after minor surgery. Evidence from small groups of patients with rheumatoid arthritis treated for a year or more suggests that proquazone may inhibit or arrest progression of bone erosions. However, these encouraging findings clearly need confirmation in a larger number of patients studied under well-controlled conditions. The overall impression from clinical trials to date is that proquazone at dosages of greater than or equal to 900 mg/day produces a high incidence of gastrointestinal symptoms such as diarrhoea (in approximately 30% of patients). However, these effects were usually of mild to moderate severity and transient in nature and in most comparative studies the overall tolerability of proquazone was assessed as being comparable to that of other NSAIDs tested. Similarly, withdrawal from therapy due to side effects was no greater with proquazone than with other NSAIDs evaluated. Initial experience with lower dosages of proquazone (300 to 450 mg/day) suggest that efficacy is maintained and tolerability markedly improved. Thus, at present, proquazone would seem to be as effective as other NSAIDs used in the management of rheumatoid arthritis and osteoarthritis. However, further studies are needed to fully evaluate the efficacy and tolerability of this agent, especially at the lower daily dosages currently recommended, and to clarify whether it does have significant 'disease modifying' potential.

The efficacy and agreeability of a supportive drug therapy at doses of 300 mg of proquazone (Biarison) administered thrice daily was tested in an open study of 4 weeks' duration in 10 male patients suffering of clinically verified ankylosing spondylitis. The minimum duration of suffering was 15 years, the maximum 50 years. The major goal of therapy during clinical treatment was individually oriented physical therapy suited to the enhancement of residual mobility, removal of postural abnormalities and abnormalities of weight-loading as well as the maintenance of functionality for afflicted skeletal regions. In the course of this additional therapy with proquazone the functional index and activity index both displayed significant improvement (2 p less than 0.01), as compared with the control subjects. Improvement was attained as soon as 2 weeks following begin of therapy. In the course of treatment the following parameters also displayed significant improvement (2 p less than 0.05): morning stiffness, fatigue, patient's self-evaluation, Westergren one-hour-value, physician's over-all assessment, night pain, articular pain, thoracic and lumbar pain. There were only insignificant changes in other, regularly tested laboratory values during this drug therapy. No side effects or disagreeability signs of proquazone were noted. Proquazone can be recommended for the symptomatic additional treatment of patients suffering from ankylosing spondylitis.
