ObjectiveTo evaluate the analgesic efficacy of high-dose celecoxib in the treatment of moderate to extreme pain and inflammation associated with acute gouty arthritis.MethodsA multinational, randomized, double-blind, double-dummy, active-controlled trial was done with patients (aged≥18 years) with acute gouty monoarthritis or oligoarthritis (onset of pain≤48 h before enrollment). Patients were treated for 8 days with 1 week followup and were randomized 1:1:1:1 to receive celecoxib 50 mg bid, celecoxib 400 mg (followed by 200 mg later on Day 1 and then 200 mg bid for 7 days), celecoxib 800 mg (followed by 400 mg later on Day 1 and then 400 mg bid for 7 days), or indomethacin 50 mg tid.ResultsOf 443 patients screened, 402 were randomized and 400 received treatment. Baseline demographics were comparable among treatments. Patients receiving high-dose celecoxib (800/400 mg) experienced a significantly greater reduction in pain intensity on Day 2 compared with low-dose celecoxib 50 mg bid [least squares (LS) mean difference -0.46; p=0.0014]. For high-dose celecoxib 800/400 mg, the change in pain scores from baseline to Day 2 was comparable with indomethacin 50 mg tid (LS mean difference 0.11; p=0.4331). There were significant differences in adverse events when the combined celecoxib groups (29.5%) were compared with patients taking indomethacin (43.1%; p=0.0116). There was no change in median serum creatinine levels for any treatment. There were more discontinuations due to adverse events (8.8% vs 3%; p=0.0147) with indomethacin than with the combined celecoxib groups.ConclusionHigh-dose celecoxib (800/400 mg) was significantly more effective than low-dose celecoxib (50 mg bid) and comparable to indomethacin in the treatment of moderate to extreme pain in patients with acute gouty arthritis. Further, celecoxib was well tolerated.
