Abstract
- Background and Aim: Herbal products are widely used to treat patients with disorders of gut brain interaction but clinical efficacy and safety data for treatments lasting >4 weeks are widely lacking. We evaluated the efficacy and safety of 8 weeks of treatment with the herbal combination product STW 5‐II for patients with functional dyspepsia (FD) meeting Rome II criteria. We also conducted a post hoc analysis including patients meeting Rome IV criteria for FD and evaluated the effect of the G‐protein beta 3 (GNB3) subunit polymorphism (C825T) on therapeutic response. Methods: This multicenter, placebo‐controlled, double‐blind study included 272 FD patients meeting Rome II criteria in the intention‐to‐treat cohort and 266 meeting Rome IV criteria. We used the validated Gastrointestinal Symptom Score (GIS) to assess GI symptoms, defining response rate as the proportion of patients with ≥50% GIS improvement in at least three of four assessments. Results: After 8 weeks, the response rate was significantly higher in the STW 5‐II group versus placebo (61.2% vs 45.1%, P = 0.008). Mean GIS non‐significantly improved with STW 5‐II treatment (7.9 ± 4.41 vs 6.7 ± 4.91 with placebo; P = 0.07). In the Rome IV subgroup analysis, STW 5‐II yielded a better response rate (P = 0.01) versus placebo and greater postprandial distress symptom improvement (P = 0.04) versus placebo. Safety parameters did not differ between groups, and GNB3 status was not linked with therapeutic response. Conclusion: STW 5‐II is efficacious, with no observed safety signals at up to 8 weeks of treatment in patients with FD meeting Rome II or IV criteria. [ABSTRACT FROM AUTHOR]
