Study on the Efficacy and Safety of Tongluo Kaibi Tablets in the Treatment of Fibromyalgia Syndrome

Fibromyalgia is a chronic, disabling musculoskeletal pain disorder. Pregabalin is the sole pharmaceutical agent approved for the treatment of fibromyalgia in China. Tongluo Kaibi Tablet, an approved proprietary Chinese medicine with collaterals-dredging and blood-activating effects, has demonstrated potential therapeutic benefits for fibromyalgia in preliminary small-scale observational studies, yet high-quality large-sample clinical evidence remains lacking. This multicenter, randomized, double-blind, double-dummy parallel-controlled clinical trial was conducted to evaluate the clinical efficacy and safety of Tongluo Kaibi Tablet in patients with fibromyalgia syndrome.
