摘要

OBJECTIVE: To compare the efficacy and safety of S-etodolac with etodolac in the treatment of osteoarthritis in Indian patients. MATERIALS AND METHODS: This was a double-blind, multicentric, comparative clinical trial conducted in 108 Indian patients with osteoarthritis. All patients received either S-etodolac ER 300 mg or etodolac ER 600 mg tablets once daily. Assessment was done on the basis of WOMAC score and VAS pain score, patient's and physician's global assessment of the arthritic condition. All patients were evaluated after every 2 weeks for 4 weeks for efficacy and safety variables. RESULTS AND DISCUSSION: Total 49 patients in the test group and 52 patients in the reference group completed the study. There was significant improvement (p < 0.0001) in all WOMAC subscales (pain, stiffness and physical function), WOMAC total score and VAS pain score in both the groups. Patient's and physician's global assessment of the arthritic condition also improved significantly (p < 0.0001). All patients showed improvement in WOMAC and VAS pain score by (3) 20%. There was no significant difference between the groups for the efficacy parameters. The adverse events reported were few and no serious adverse events were reported. Total 5 patients in S-etodolac group and 2 patients in etodolac group dropped out of the study. Only 1 patient dropped out because of the side effects of burning sensation, palpitations and anxiety in the test group. CONCLUSION: The present study has established the efficacy, tolerability and safety of S-etodolac extended release tablets in the treatment of osteoarthritis in Indian patients.
