Zuojin Wan Combined With Rabeprazole or Mosapride for the Treatment of Functional Dyspepsia Combined With Depression

A Single-centre Randomised Controlled Study of 4-week Zuojin Pills in Combination With Sodium Rabeprazole Enteric-coated Tablets or Mosapride Citrate for the Treatment of Functional Dyspepsia Combined With Depression

To evaluate the symptom improvement of Zuojinwan combined with rabeprazole or Zuojinwan combined with a mosapride regimen in patients with functional dyspepsia combined with depression (liver-stomach depression-heat type) using rabeprazole or mosapride regimen as a control, and to compare the patients' adherence to the medication and the adverse effects between the two groups.

Functional dyspepsia (FD) is the highest incidence of functional gastrointestinal disorders (FGIDs), of which the prevalence of FD combined with depression is 16.4%~22.8%, FD etiology is complex and diverse, and in the "Functional Gastrointestinal Disease Rome IV Diagnostic Criteria" released in 2016, it is clearly proposed that its nature is "brain-gut interaction disorder". The "Rome IV Diagnostic Criteria for Functional Gastrointestinal Diseases" released in 2016 explicitly proposed that its essence is "brain-gut interaction disorder", and it is due to the bidirectional regulation of the brain-gut axis that the phenomenon of combined depression is common in FD patients induced by "brain-gut interaction disorder", which is prone to clinical underdiagnosis and misdiagnosis, and also to clinical depression. It is easy to cause clinical underdiagnosis and misdiagnosis, and also brings many challenges to drug treatment. It is feasible to use Zuojinwan combined with rabeprazole sodium enteric-coated capsules or Zuojinwan combined with mosapride citrate tablets for the treatment of FD combined with depression. The aim of this study is to compare the efficacy of Zuojinwan combined with rabeprazole sodium enteric-coated capsules or mosapride citrate for the treatment of FD combined with depression with that of rabeprazole sodium enteric-coated capsules or mosapride citrate treatment alone.
