ABSTRACT BACKGROUND: Gastroesophageal reflux disease (GERD) has a high prevalence worldwide, and its incidence is increasing annually. Modified Xiaochaihu Decoction (MXD) could relieve the symptoms of GERD, but the effects of MXD on GERD manifestations and relapse prevention need to be further explained. Therefore, we performed a prospective, double-blind, and double-simulation study. AIM: To verify the efficacy of MXD for GERD and its effect on esophageal motility. METHODS: Using randomization, double-blinding, and a simulation design, 288 participants with GERD were randomized to the treatment group and control group and received herbs (MXD) plus omeprazole simulation and omeprazole plus herbs simulation, respectively, for 4 wk. The GERD-Q scale score and esophageal manometry were measured at baseline, after treatment, and at 1 mo and 3 mo follow -up visits when medication was complete to evaluate recurrence indicators. RESULTS: The GERD-Q scale score in both groups decreased significantly compared to those before treatment (P < 0.01). However, no significant difference was observed between the two groups (P > 0.05). Esophageal manometry showed that participants with lower esophageal sphincter pressure reduction and the proportion of ineffective swallowing (more than 50%) improved in both groups from baseline (P < 0.01), especially in the treatment group (P < 0.05). The percentage of small intermittent contractions, large intermittent contractions, and increased pre-phase contractions in the treatment group significantly improved compared with baseline (P < 0.05) but did not improve in the control group (P > 0.05). There was no significant difference between the groups after treatment (P > 0.05). The percentage of weak esophageal contractility (dista l contractile integral < 450 mmHg·s·cm), improved in both groups (P < 0.01), but no significant difference was observed between the groups after treatment (P > 0.05). The relapse rate in the treatment group was lower than that in the control group at the 1 mo (P < 0.01) and 3 mo follow-up (P < 0.05). CONCLUSION: MXD has a similar therapeutic effect to omeprazole in mild-to-moderate GERD. The therapeutic effect may be related to increased pressure in the lower esophageal sphincter and reduced ineffective swallowing.
