OBJECTIVE: Helicobacter pylori eradication therapy alone cannot heal gastric ulcers in Japanese patients. Irsogladine has previously been shown to accelerate the healing of gastric ulcers after H. pylori eradication therapy. And we previously reported that histamine H(2) receptor antagonists inhibit gastric ulcer relapse after H. pylori eradication therapy. We therefore compared the efficacy of irsogladine with famotidine as appropriate treatments for ulcers after eradication therapy. METHODS: Gastric ulcer patients with H. pylori infection (n = 119) were randomized to treatment with irsogladine 4 mg/day (n = 60) or famotidine 40 mg/day (n = 59) following 1-week H. pylori eradication therapy. After treatment, assessments of gastric ulcer healing were performed. RESULTS: The ulcer healing rates in patients receiving irsogladine and famotidine were 85.2% (46/54) and 79.6% (43/54), respectively, and were not significantly different (p = 0.4484). In the famotidine group, the healing rate was significantly lower in patients who drink alcohol than in those who do not (60.0% vs. 91.2%; p = 0.0119). However, in the irsogladine group the healing rate did not differ between patients who drink alcohol and those who do not. Furthermore, the healing rate in smokers was significantly higher in the irsogladine group (88.0%) than in the famotidine group (59.1%) (p = 0.0233). CONCLUSIONS: Irsogladine and famotidine are both acceptable in treatment after H. pylori eradication therapy in gastric ulcer patients. Findings also suggest that irsogladine is more beneficial than famotidine in patients who drink alcohol and smoke.
