OBJECTIVE: Frozen shoulder is a prevalent condition among individuals in their middle and later years. Invasive therapy has shown promising results in the treatment of frozen shoulders, but its widespread adoption has been hampered by high costs and the need for advanced medical technology. As a result, patients with frozen shoulders often turn to non-steroidal anti-inflammatory drugs (NSAIDs) for symptomatic relief. However, the oral administration of NSAIDs can lead to troublesome adverse effects on the gastrointestinal, cardiovascular, and urinary systems. In contrast, topical NSAIDs have gained attention for their excellent efficacy and lower adverse effects in various chronic pain conditions. Therefore, our study aimed to investigate the efficacy and safety of topical NSAIDs in improving pain and mobility among patients with frozen shoulders.

PATIENTS AND METHODS: A total of 108 patients experiencing moderate to severe pain and mobility impairment due to frozen shoulder were enrolled in this study. The participants were randomly assigned to either the experimental group (n=72) or the control group (n=36). The experimental group received daily treatment with the loxoprofen hydrogel patch (LOX-P) in addition to basic rehabilitation physiotherapy. The control group was treated with flurbiprofen cataplasm (FLU-C) twice a day, along with rehabilitation physiotherapy. The primary endpoint for evaluating the efficacy of the two patches was the Constant-Murley score (CMS). Clinical symptom data, adverse events, and patient satisfaction were also recorded.

RESULTS: After 14 days of treatment, the effective rate was 66.67% (n=48) in the experimental group and 41.67% (n=15) in the control group. The overall difference in the effective rates was 25.00% (95% CI=5.20-42.52; p=0.013). The safety profiles of the two topical agents were similar, with only a few adverse events reported.

CONCLUSIONS: The loxoprofen hydrogel patch demonstrates a significant ability to alleviate shoulder pain and restore shoulder function in the treatment of frozen shoulder, with minimal adverse reactions.
