Completed clinical study compared the treatment effects of rabeprazole and lansoprazole depending on the genetic constitution of a enzyme in the liver in treating reflux esophagitis and the cure rate on endoscopy after treatment with rabeprazole 20 mg or lansoprazole 30 mg once daily for 4 to 8 weeks.
