ABSTRACT

Objective To observe the clinical efficacy of Simotang oral liquid combined with compound glutamine enteric capsules in the treatment of diarrhea-predominant irritable bowel syndrome (IBS-D) belonging to liver depression and spleen deficiency pattern, and to explore its possible mechanism. Methods Sixty patients were randomly divided into two groups. The treatment goup (30 cases) took Simotang oral liquid and compound glutamine enteric capsules, the control group took Cerekinon and Medilac-S. The treatment course was 4 weeks. Clinical symptoms, 5-hydroxytryptamine (5-HT) and substance P (SP) of both groups were evaluated respectively before and after treatment. Recurrence rate and adverse reactions were recorded. Results The total effective rate after treating 1, 2, 4 weeks between the two groups had no significant difference (P>0.05). Four weeks later, in the treatment group, total score of the symptoms, abdominal distension and defecation urgency were apparently lower than that of control group (P0.05). Obvious side effects were not found in the two groups. Conclusion Simotang oral liquid combined with compound glutamine enteric capsules has evident therapeutic effect on IBS-D of liver depression and spleen deficiency pattern, especially good at releasing abdominal distension and defecation urgency. The mechanism may be related with decreasing the levels of 5-HT and SP.
