A Study of Lianxiaxiaopi Granules in the Treatment of Postprandial Distress Syndrome

The goal of this clinical trial is evaluating the efficacy and safety of Lianxiaxiaopi Granules in participant population. The main questions it aims to answer are: 1. Based on the Response rate of postprandial distress syndrome participants, evaluate whether the efficacy of Lianxiaxiaopi Granules is superior to placebo. 2. Evaluate the efficacy of Lianxiaxiaopi Granules in improving symptom of postprandial distress syndrome. 3. Evaluating the safety of Lianxiaxiaopi Granules in postprandial distress syndrome participants.

Acotiamide vs Itopride in Postprandial Distress Syndrome

The goal of this study is to "To compare the efficacy and safety of Acotiamide versus Itopride in patient with post prandial distress syndrome type of functional dyspepsia"

Postprandial Distress Itopride Cohort Trial

Functional Dyspepsia (FD) is a common gastrointestinal disorder affecting about 7.2% of the population, characterized by gastroduodenal symptoms without an identifiable organic cause. It is divided into two subtypes based on the Rome IV criteria: (i) Postprandial Distress Syndrome (PDS): Meal-related symptoms like postprandial fullness and early satiation.; (ii) Epigastric Pain Syndrome (EPS): Meal-unrelated symptoms like epigastric pain or burning. Treatment options are limited, but prokinetics are commonly used, targeting suspected motility issues. A meta-analysis showed prokinetics reduce symptoms. Itopride, a D2 antagonist and acetylcholinesterase inhibitor, has shown potential efficacy, especially in Asian populations. As Itopride became available in Belgium since 2023, there is a lack of real-life outcome data in Western patients with functional dyspepsia/postprandial distress syndrome who receive treatment in standard clinical practice. Hence, the aim of this pragmatic observational study is to follow up a cohort of functional dyspepsia/postprandial distress syndrome patients in whom itopride treatment is started as part of routine clinical practice.

Primary Care dySpEpsia rikkuNshiTo

Dyspepsia refers to chronic or recurrent upper gastrointestinal (GI) symptoms originating from the gastroduodenal region with a significant impact on patients' lives. Functional dyspepsia comprises the diagnostic categories of epigastric pain syndrome (EPS) with epigastric pain or burning and postprandial distress syndrome (PDS) with meal-related fullness or early satiation, which are unexplained after routine investigation including upper GI endoscopy 2. Despite the common occurrence of FD in up to 15% of the general population, the underlying pathophysiology remains unclear and no treatments of proven efficacy are available in Europe for this condition. Our group has demonstrated increased duodenal mucosal permeability and low-grade inflammation in FD patients, correlating with meal-related symptoms. The causes of the barrier defect and immune activation are unknown but candidates include psychological stress, luminal food components, (bile) acid and microbiota. The symptoms most closely associated with increased eosinophil counts in the duodenum are early satiation and postprandial fullness, which are typical PDS symptoms, and which are also associated with impaired gastric accommodation to meal ingestion and delayed gastric emptying. Previously the efficacy of the Kampo medicine Rikkunshito (TJ-43) has been shown in FD. The exact mode of action remains to be determined. Previous studies have provided mechanistic evidence that rikkunshito is able to improve gastric accommodation, improve food intake and enhance circulating levels of the orexigenic gut peptide ghrelin. The aim of this study is to evaluate the efficacy of Rikkunshito in comparison to placebo in PDS patients recruited from primary care in Belgium, and to evaluate whether this is associated with changes in duodenal mucosal low-grade inflammation.
