Alclofenac: a review of its pharmacological properties and therapeutic efficacy in rheumatoid arthritis and allied rheumatic disorders

Alclofenac is a non-steroidal anti-inflammatory agent advocated for use in rheumatoid arthritis, degenerative joint disease and ankylosing spondylitis. Published data to date, suggest that alclofenac 3g daily is comparable in efficacy with aspirin 4.8g daily, phenylbutazone 300 to 600mg daily and indomethacin 150mg daily. In Welsh patients, gastro-intestinal side-effects have generally been less frequent and milder than with the standard comparison drugs, but in Other populations differences in the overall incidence of these side-effects have been less marked. Results of a long-term trial, as evidenced by alterations in certain biochemical indications of disease activity, suggest that alclofenac may possibly reduce the severity of the disease itself, but further studies will be needed to confirm this. However, at present alclofenac should be considered along with the Other drugs of its type in the initial treatment of the arthritic patient. Skin rash is the most frequent side-effect, which in a small proportion of affected patients may be associated with systemic effects. A cutaneous reaction appears to be more likely in patients with a history of previous allergy to penicillin and Other drugs.
