A comparison of the efficacy and tolerability of meloxicam and diclofenac in the treatment of patients with osteoarthritis of the lumbar spine

Abstract:

Objective: The aim of this study was to evaluate the efficacy and tolerability of meloxicam compared with diclofenac in patients with osteoarthritis of the lumbar spine.¶Subjects: 229 patients with radiologically confirmed osteoarthritis of the lumbar spine.¶Treatment and Methods: Once-daily meloxicam 7.5 mg tablet or diclofenac 100 mg slow release tablet. Efficacy and tolerability parameters were assessed at baseline and after 3, 7 and 14 days of treatment.¶Results: The two drugs had equal short-term efficacy, with pain on motion of lumbar spine significantly (p<0.05) decreased at Day 3. Secondary efficacy variables were also significantly improved at Days 3, 7 and 14. There were no statistically significant differences between the two drugs, although the global tolerability of meloxicam was significantly better than for diclofenac, as assessed by the investigators (p = 0.0072) and the patients (p = 0.049).¶Conclusions: Meloxicam and diclofenac were equivalent in relieving the acute pain associated with osteoarthritis of the lumbar spine. However, meloxicam was much better tolerated.¶
