Gastroesophageal Reflux Disease
Conditions
Brief summary
The purpose of this study is to investigate the efficacy of lansoprazole combination with domperidone on intragastric acidity and intraesophageal acidity, GERD symptoms, impedance kinetics, gastric emptying in patients with gastroesophageal reflux disease (GERD).
Detailed description
Objectives of the trial to assess the efficacy of lansoprazole in combination with domperidone on gastric acidity, intraesophageal acidity, GERD symptoms, impedance kinetics and gastric emptying in patients with GERD. 24 hour pH measurement and gastric emptying test will be done at screening visit and after 7 days of drug treatment. Twelve patients will take one tablet for 7 days.
