Efficacy and Safety of Zuojin Pill for the Treatment of Chronic Nonatrophic Gastritis: A Randomized Active-Controlled Clinical Trial

Abstract

Objective. Zuojin pill (ZJP) is used as the classical prescription for a wide variety of digestive diseases. However, there is a lack of direct evidence for its use in the treatment of chronic nonatrophic gastritis (CNG). In particular, there is a lack of rigorous trials of randomized controlled designs. In this study, a randomized active-controlled clinical trial was performed to verify the efficacy and safety of ZJP in detail. Methods. Patients with CNG were divided into the ZJP group and the Marzulene-S granule group. Patients were enrolled from September 2019 to February 2021 (ChiCTR2000040549). Endoscopy and histology scores were evaluated as the primary outcome measure. The Helicobacter pylori positive rate and the disappearance rate of symptoms were also measured to reflect the outcomes. Finally, adverse events were also calculated as the index of safety. Results. A total of 68 eligible patients were enrolled in this trial and randomly divided into two groups with baseline comparability. ZJP was able to improve the red plaques as well as bile reflux scores compared with Marzulene-S granule ( P = 0.043 and P = 0.019 , respectively). Moreover, it also remarkably alleviated the active chronic inflammation score P = 0.043 . However, there was no difference between the Helicobacter pylori positivity rate P = 0.752 . The symptom scores of abdominal distension P = 0.004 , belching P = 0.010 , and loss of appetite P = 0.019 were alleviated by ZJP, but nausea and vomiting were not P = 0.616 . ZJP can also be considered safe with no obvious adverse effects. Conclusion. ZJP might decrease mucosal injury and alleviate symptoms in CNG. In addition, more large-scale clinical trials should be carried out to further confirm its clinical efficacy and safety.

Zhuyu Pill Alleviates Nonalcoholic Fatty Liver Disease by Regulating Bile Acid Metabolism through the Gut–Liver Axis

“…Huaglian (Coptidis rhizoma)–Wuzhuyu (Evodiae Fructus) is a well-known herb pair combination (HYHP) that is commonly used for the treatment of liver, gallbladder, and digestive diseases. − Recent research has revealed that HYHP contains several active chemicals, including berberine and evodiamine, which have diverse pharmacological effects, such as anti-inflammatory, anti-fibrotic, barrier protection, flora regulation, and lipid-lowering properties. − Zhuyu Pill (ZYP, Huanglian and Wuzhuyu in a 1:1 ratio, g/g) is a traditional HYPY formula. Previous studies have demonstrated that ZYP effectively reduces inflammation and hepatic steatosis in mice by suppressing the NLRP3 inflammasome .…”
