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.

Primary Completion Date: July 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
Treatment with lansoprazole (30 mg) once daily for 14 days
Drug: lansoprazole
lansoprazole, 30 mg, once daily for 14 days
Other Name: Takepron (brand name)
Active Comparator: 2
Treatment with mosapride (5 mg) thrice daily for 14 days
Drug: mosapride

Detailed Description:
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.
