Safety and efficacy of etodolac compared with piroxicam in patients with degenerative joint disease of the knee.
The efficacy and safety of etodolac and piroxicam were compared in a double-blind, randomized, parallel-group outpatient study at four sites. Patients with active osteoarthritis of the knee were assigned to receive etodolac 600 mg/day (57 patients) or piroxicam 20 mg/day (59 patients) for 6 weeks. Efficacy assessments were made at the pretreatment screening, at baseline, and at treatment weeks 2, 4, and 6 for patient and physician global evaluations, night pain, spontaneous pain intensity, weight-bearing pain variables, measures of inflammation, morning stiffness, and knee flexion. An analysis was also done based on each patient's final evaluation, regardless of the week at which it occurred. Safety assessments were made before treatment and at the completion of therapy. A therapeutic response was obtained in both treatment groups by the end of the second week of treatment. At the final evaluation, both groups showed significant improvement (P less than or equal to 0.05) from baseline for most efficacy assessments. The physician's global assessment indicated improvement in the condition of 60% of the etodolac-treated patients and 39% of the piroxicam-treated patients at the final evaluation. There was no significant difference between treatment groups in the number of patient withdrawals due to adverse reactions or in the number of patients reporting side effects. The results of this study indicate that, compared with piroxicam 20 mg/day, etodolac 600 mg/day is effective and well tolerated in the treatment of patients with osteoarthritis.
