Clinical Study, Multicenter, Randomized With 2 Arms of Pantoprazole + Domperidone and Pantoprazole Isolated at the Gastroesophageal Reflux Disease (PANDA)

This superiority phase III study to compare the combination of Pantoprazole and Domperidone with Pantoprazole isolated to the treatment of gastroesophageal reflux disease. The hypothesis is that combination of the two medication at the unique capsule is better to the patients because decrease the quantity of times the patients need to take medicines during the day.
