Long-term therapy with tolmetin in rheumatoid arthritis.

Abstract

Data from over 1000 patients with rheumatoid arthritis who received tolmetin sodium in double-blind and open studies have been pooled to assess long-term efficacy and safety. Duration of the studies was 12 weeks to 48 months. Mean age of patients was 54 years; ratio of males to females was 1:3. The results showed that tolmetin provided rapid onset of action and continuous progressive decrease in symptoms in all measurements of inflammation. Mean number of painful joints was reduced from 22 at baseline to 16 at one month, to 9 at one year, and to 6 at two years. Duration of morning stiffness was 155 minutes at baseline, 123 minutes at one month, 74 minutes at one year, and 78 minutes at two years. The final global evaluation by the investigators showed that 61 per cent of patients had a marked or moderate response. Mean erythrocyte sedimentation rates did not increase during therapy with tolmetin. Initial dose of tolmetin in the patients pooled for this analysis was generally 600 to 800 mg/day, and the mean dose throughout the study was 1256 mg/day. The drug was well tolerated overall. As anticipated, gastrointestinal symptoms were the most frequently reported; nausea was experienced by 13 per cent of the patients at some time during therapy, and gastrointestinal distress, dyspepsia, or abdominal pain was reported by approximately 8.6 per cent each. Only 12.7 per cent of patients discontinued tolmetin because of untoward reactions; 15.9 per cent of patients discontinued because of insufficient therapeutic response. The results of these long-term studies of patients with rheumatoid arthritis demonstrated that tolmetin is an effective antiinflammatory agent with an acceptable record of safety.
