Irritable bowel syndrome (IBS) is a common gastrointestinal functional disorder with no effective therapy. Traditional Chinese medicine (TCM) is one of the most common complementary therapies in China. We designed this study to evaluate the efficacy and safety of Shun-Qi-Tong-Xie Granule (SQTX Granule), a TCM treatment, in patients with IBS with diarrhea (IBS-D).
A randomised, double-blinded, placebo-controlled, multi-centre, superiority clinical trial to evaluate the efficacy and safety of SQTX Granule is proposed. Eligible patients (Rome III) with IBD-S will be randomly assigned into SQTX Granule group and the placebo group. Patients will receive a 28-day treatment and a 2-month follow-up. The primary outcome measures include the scores of IBS-quality of life (IBS-QOL) rating scale and IBS-symptom severity scale (IBS-SSS) rating scale. The secondary outcome measures include the improvement of symptom scores, and the duration of abdominal pain and diarrhea.
According to TCM theory, SQTX Granule has a regulating effect on abdominal pain, diarrhea and the syndrome of liver-spleen disharmony, which is similar to the symptoms of IBS-D. This study will provide objective evidence to evaluate the efficiency and safety of SQTX Granule in IBS-D treatment.
