    Abstract:
    Rebamipide, a gastroprotective drug developed in Japan, accelerates ulcer healing and reduces recurrence of experimental gastric ulcers. We examined the effects of rebamipide, given during healing of human gastric ulcers infected with Helicobacter pylori, on the quality of ulcer healing and ulcer recurrence. Sixty H. pylori-positive patients with gastric ulcers were randomly allocated to three treatment groups: group O (N = 20) received 20 mg of omeprazole every day for eight weeks, group OR (N = 20) received the same dose of omeprazole and 300 mg of rebamipide three times a day for eight weeks, and group OA (N = 20) received the same dose of omeprazole for eight weeks and 1500 mg of amoxicillin three times a day for the first two weeks. After this treatment was completed no other medication was given. Endoscopic examinations were performed at the end of therapy (for healing rate), one month later (for rate of H. pylori eradication) and every three months for follow-up (for ulcer recurrence rate). At the end of therapy, biopsy specimens were taken from the gastric ulcer scar and examined under the microscope for neutrophil and mononuclear cell infiltration. The ulcer healing rate of the three groups was almost the same; H. pylori in group OA was 65% and that of the other two groups was 0%. The number of patients with a flat ulcer scar pattern (good quality of ulcer healing) was increased and the neutrophil infiltration was significantly improved in groups OR and OA compared to group O. The ulcer recurrence rate was significantly lower in group OA and group OR than in group O. In conclusion, rebamipide is almost equipotent to amoxicillin plus omeprazole for the reduction of ulcer recurrence. The decreased recurrence rate by rebamipide may be due to improvement of the quality of ulcer healing, reflected as in the suppression of inflammatory cell infiltration in the scar, which results from either cure of H. pylori infection and/or treatment with a gastroprotective drug such as rebamipide.
