OBJECTIVE: Osteoarthritis (OA) is a chronic progressive degenerative disease of weight-bearing joints and the leading cause of disability in elderly. Current medical management of OA is mostly palliative with nonsteroidal anti-inflammatory drugs (NSAIDs) being the mainstay of therapy. Reports of gastrointestinal adverse effects with traditional NSAIDs and cardiovascular adverse effects associated with selective cyclooxygenase-2 (COX-2) inhibitors have prompted the hunt for a better NSAID with no or minimal adverse effects. This study compares the clinical effectiveness and safety of newer NSAIDS etodolac and lornoxicam to diclofenac which has been a standard therapy in patients of OA of knee joint. MATERIALS AND METHODS: It was a randomized, prospective, open-label, parallel-group study conducted in 90 patients of OA of knee joint diagnosed according to the American College of Rheumatology criteria. After obtaining the informed consent, they were randomized in three groups of 30 patients each who received tablet etodolac 400 mg b.i.d, tablet lornoxicam 8 mg b.i.d, and tablet diclofenac sodium 50 mg t.i.d, respectively. The duration of the study was 12 weeks. Data were tabulated and analyzed using analysis of variance (ANOVA) test, and level of significance was determined by its P value. RESULTS: After 12 weeks of treatment, pain intensity and functional indices in terms of visual analog scale and Western Ontario and McMaster Universities Osteoarthritis score were significantly better (P < 0.05) in lornoxicam group as compared to etodolac or diclofenac group along with lesser rate of adverse effects. CONCLUSION: It was concluded that lornoxicam was more effective and better tolerated NSAID than etodolac and diclofenac in treatment of knee joint OA.
