Study designs: Randomized Controlled Trial, Clinical Trial
Abstract: BACKGROUND For the treatment of gastritis, rebamipide, a mucoprotective agent, and nizatidine, a gastric acid suppressant, are commonly employed individually. AIM To compare the efficacy of Mucotra® SR (rebamipide 150 mg) and Axid® (nizatidine 150 mg) combination therapy with the sole administration of Axid® in managing erosive gastritis. METHODS A total of 260 patients diagnosed with endoscopically confirmed erosive gastritis were enrolled in this open-label, multicenter, randomized, phase 4 clinical trial, allocating them into two groups: Rebamipide/nizatidine combination twice daily vs nizatidine twice daily for 2 weeks. The full-analysis set analysis encompassed 239 patients (rebamipide/nizatidine, n = 121; nizatidine, n = 118), while the per-protocol analysis included 218 patients (n = 110 vs 108). Post-treatment assessments comprised primary (erosion improvement rate) and secondary (erosion and edema cure rates, erythema improvement rates, hemorrhage, and gastrointestinal symptoms) endpoints. Furthermore, drug-related adverse effects were evaluated. RESULTS Primary efficacy assessment showed a statistically significant improvement rate in mucosal erosions in the combination group compared to the control group in the full-analysis set (rebamipide/nizatidine 62.0%, nizatidine 49.2%, P = 0.046), with a similar trend noted in the per-protocol analysis (62.7% vs 50.0%, P = 0.058). Both groups were effective in curing erosion and edema and improvement of bleeding, erythema, and gastrointestinal symptoms, whereas no inter-group differences were noted. When confined to the participants with gastritis symptoms, improvement of erosion was more optimal in the combination group (63.0% vs 49.5%, P = 0.046). No adverse events related to the drugs were observed. CONCLUSION Rebamipide/nizatidine combination is effective in treatment of erosive gastritis.
