ObjectiveTo analyze the clinical efficacy of etofenamate gel in patients with chronic trauma of locomotion system. MethodsRandomized parallel-controlled trial was conducted. From September 2011 to March 2012, 120 patients who were diagnosed with chronic trauma of locomotion system were divided into two groups. One was etofenamate gel group (group A), and the other was diclofenac sodium cream group (group B). Treatment course was two weeks. ResultsAfter two weeks of therapy, the effective rate of etofenamate gel was 85.0%, and of diclofenac sodium cream was 83.3%. The difference between etofenamate gel and diclofenac sodium cream had no statistical significance. Two drugs had similar efficacy in treating chronic trauma of locomotion system. Two patients in the etofenamate gel group and three in the diclofenac sodium cream group had very slight adverse reactions. ConclusionEtofenamate gel is effective in patients with chronic trauma of locomotion system, and the efficacy is similar with diclofenac sodium cream. It is particularly suitable for patients with gastrointestinal diseases.
