Functional Dyspepsia Clinical Trial
Official title:
A Comparative Study of Lansoprazole and Mosapride for Functional Dyspepsia: Focus on Difference Between Epigastric Pain Syndrome and Postprandial Distress Syndrome
Functional dyspepsia is a common symptom complex with significant impact on quality of life.
There is no standard treatment for functional dyspepsia but therapeutic efficacy of proton
pump inhibitor (PPI) and prokinetic agent have been proved in subsets of patients. This
study has two aims:
- first is to compare the therapeutic efficacy of lansoprazole (a PPI) and mosapride (a
prokinetic agent) for functional dyspepsia
- second is to investigate whether different subgroups of functional dyspepsia (e.g.,
epigastric pain syndrome and postprandial distress syndrome) respond differently to PPI
and prokinetic agent.
Eligible outpatients with presentation of dyspepsia are enrolled if they fulfilled the criteria of ROME III criteria. A trained assistant helps the eligible patients to complete the ROME III standard questionaire, brief symptom rating scale (BSRS), and Maudsley Personality Inventory (MPI). The enrolled patients are then randomized into either lansoprazole or mosapride group for 14-day treatment. Before starting medication, right after completing the medication, and 1 month after the medication, the enrolled patients complete standardized severity questionnaire (Hong-Kong Index) to evaluate severity of dyspeptic symptoms. Symptom improvement is then determined. ;
