RESUMO
Valdecoxib, a COX-2 inhibitor, has been introduced as a new treatment for osteo-arthritis (OA). The present study was conducted to evaluate the efficacy, safety and tolerability of valdecoxib, in OA patients in an Indian setting. The present 4-week study was a prospective, non-comparative, assessor blind, single group, multicentric trial with OA patients treated with valdecoxib, 10 mg once a day. Efficacy was assessed by analysing the changes in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), visual analogue scale (VAS), patient's and physician's global assessment of arthritis. The incidence of adverse events was monitored throughout the study. There was a clinical and statistical significant improvement in the mean pain score, stiffness score, physical function, composite WOMAC index score and VAS (p<0.05). Patient's and physician's global evaluation of valdecoxib treatment was very good to good in 84.1% and 83.6% of cases respectively. The present study has shown that valdecoxib, in a dose of 10 mg/day given over 4 weeks, is an effective and safe treatment for the signs and symptoms of OA of hip and knee joints.
