AIMS To investigate if mosapride, a prokinetic agent, was an effective adjunct to acid suppression in improving the symptoms of reflux oesophagitis. METHODS Patients (n = 96) with reflux oesophagitis were randomly assigned to either mosapride (5 mg three times daily) or placebo for 4 weeks. Symptom severity was assessed by a validated questionnaire at enrolment, 4 and 8 weeks after medication. The primary outcome for the first 4 weeks was decrease in symptom scores. After a 3 day washout period, patients initially allocated to mosapride crossed over to placebo and vice versa for the next 4 weeks. The outcome of the second phase was maintenance of symptom control. All patients received lansoprazole (30 mg once daily) throughout study. RESULTS The decreased symptom score after 4 weeks of treatment with lansoprazole and mosapride (n = 50) was 13.42 ± 1.16 (mean ± SEM), similar to that of lansoprazole plus placebo (10.85 ± 1.03, n = 46), with an insignificant difference of 2.57 (95% CI -0.53, 5.67, P = 0.103). However, a sub-group analysis for patients with pre-treatment scores of >18 points (n = 48) revealed that lansoprazole plus mosapride achieved a greater reduction of symptom score than lansoprazole plus placebo (18.22 ± 1.91 vs. 12.88 ± 1.65; mean difference of 5.34, 95% CI 0.28, 10.40, P = 0.039). In the second phase, there was no difference between lansoprazole with mosapride or placebo in maintaining symptom control (39/44 or 86.64% vs. 41/50 or 82%, P = 0.401). Subgroup analysis for those with substantial residual symptoms revealed similar results. CONCLUSION Compared with placebo, mosapride generally does not provide additional benefit to a standard dose of lansoprazole in patients with reflux oesophagitis, except possibly in the subgroup of severely symptomatic patients.
