Assessing the efficacy of famotidine and rebamipide in the treatment of gastric mucosal lesions in patients receiving long-term NSAID therapy (FORCE--famotidine or rebamipide in comparison by endoscopy).

<bold>Background: </bold>Nonsteroidal anti-inflammatory drugs (NSAIDs) and Helicobacter pylori infection are major causes of gastric mucosal lesions. In Japan, histamine-2 receptor antagonists are frequently prescribed, but the literature regarding their efficacy is limited. In this study, we compare the effects of famotidine and rebamipide on NSAID-associated gastric mucosal lesions using upper gastrointestinal endoscopy.<bold>Methods: </bold>This study examined 112 patients taking NSAIDs for either gastric hemorrhage or erosion. Before treatment, the patients were assessed by endoscopy. Using blind randomization, patients were divided into two groups: group F (famotidine, 20 mg/day) and group R (rebamipide, 300 mg/day). Efficacy was examined 4 weeks later using endoscopy.<bold>Results: </bold>After treatment, the Lanza score decreased significantly in group F (P < 0.001) but not in group R (P = 0.478). The change in the Lanza score in group F was significantly greater (P = 0.002) than that in group R.<bold>Conclusions: </bold>Famotidine was superior to rebamipide in treating NSAID-associated mucosal lesions.
