Cisapride versus ranitidine in the treatment of reflux esophagitis.

The healing effect of the prokinetic drug cisapride (10 mg q.i.d.) on esophageal lesions, and its therapeutic control of gastroesophageal reflux symptoms were compared with the effects of the H2-antagonist ranitidine (150 mg b.i.d. + placebo b.i.d.) in a double-blind trial. In each group, 28 patients with Savary-Miller Grade I or II esophagitis were treated for 6 or 12 weeks. At the end of treatment, follow-up endoscopy showed that mucosal lesions were absent in 89% of the cisapride patients and in 79% of the ranitidine patients. In addition, 86% and 82% of the patients in the cisapride and the ranitidine group, respectively, had no, or only mild, reflux symptoms. Minor side effects were experienced in both groups. From these data, cisapride appears to be as effective as ranitidine in controlling reflux symptoms and in promoting the healing of mucosal lesions in milder forms of reflux esophagitis.
