Background Patients with reflux esophagitis have a high rateof relapse within one year after therapy is discontinued.
Methods We enrolled 175 adults with endoscopy-confirmed refluxesophagitis in a prospective study comparing five maintenancetherapies. All the patients were initially treated with omeprazole(40 mg orally once a day) for four to eight weeks, and healingwas confirmed by endoscopy. Participants were then stratifiedaccording to their initial grade of esophagitis and randomlyassigned to 12 months of treatment with one of the following:cisapride (10 mg three times a day), ranitidine (150 mg threetimes a day), omeprazole (20 mg per day), ranitidine plus cisapride,or omeprazole plus cisapride. Endoscopy was repeated after 6and 12 months of treatment; the endoscopists were blinded tothe treatment assignments. Remission was defined as the absenceof esophageal lesions on scheduled or unscheduled follow-upendoscopy.
Results In an intention-to-treat analysis, the numbers of patientsin continued remission at 12 months were 19 of 35 (54 percent)in the cisapride group, 17 of 35 (49 percent) in the ranitidinegroup, 28 of 35 (80 percent) in the omeprazole group, 23 of35 (66 percent) in the ranitidine-plus-cisapride group, and31 of 35 (89 percent) in the omeprazole-plus-cisapride group.Omeprazole was significantly more effective than cisapride (P= 0.02) or ranitidine (P =0 .003), and combination therapy withomeprazole plus cisapride was significantly more effective thancisapride alone (P = 0.003), ranitidine alone (P<0.001),or ranitidine plus cisapride (P = 0.03). Ranitidine plus cisapridewas significantly better than ranitidine alone (P = 0.05).
Conclusions For maintenance treatment of reflux esophagitis,omeprazole alone or in combination with cisapride is more effectivethan ranitidine alone or cisapride alone, and the combinationof omeprazole and cisapride is more effective than ranitidineplus cisapride.
