Aim. To compare the effectiveness of omeprazole versus lansoprazole with amoxicillin and clarithromycin in the Turkish populations with duodenal ulcer.
Methods. Helicobacter pylori positive 108 patients with active duodenal ulcer randomized double blindly into 2 groups. In the group of omeprazole, amoxicillin and clarithromycin (OAC), 54 patients; 34 male, 20 female, average age (±SD) 43.89±11.77 years. Omeprazole was given 20 mg b.i.d, half an hour before meals for 14 days and then 20 mg preceeding breakfast for 6 weeks along with 1 g amoxicillin and 500 mg clarythromycin b.i.d. for both antibiotics for 14 days while lansoprazole 30 mg b.i.d. was administered half an hour preceeding food intake for 14 days and then 30 mg prebreakfast for 6 weeks with concordant 1 g b.i.d. amoxicillin and clarythromycin 500 mg, b.i.d. for 14 days in the group of lansoprazole with amoxicillin and clarithromicin (LAC) (54 patients; 31 male, 23 female, average age (±SD) 40.85±12.80 years. The patients were evaluated in clinical terms and by endoscopic parameters for healing, H. pylori eradication and drug side effects before and after 8 weeks of treatment.
Results. There were no significant differences in age, sex and smoking between the 2 groups (p=0.20, p=0.56, p=0.85), respectively. In the LAC group, the ulcer healing rate was 94.4% (51 out of 54 patients). H. pylori was eradicated in 49 patients out of 54 (90.7%). The H. pylori eradication rate was 89.7% (26 out of 29) among the smokers. In the OAC group the ulcer healing rate was 90.7% (49 out of 54 patients). H. pylori was eradicated in 43 patients out of 54 (79.6%). The H. pylori eradication rate was 80.0% (24 out of 30 patients) among the smokers. There was no statistical difference between the 2 groups for ulcer healing (p=0.72). There was also no statistical difference for H. pylori eradication between the LAC and OAC groups (p=0.10). Although mild side effects were observed in both groups, there was no indication for stoping the therapy.
Conclusion. This study has shown that the 2 regimens (LAC and OAC) are highly effective in healing duodenal ulcers and eradicating H. pylori. Lansoprazole does not appear to have a significant advantage over omeprazole either in ulcer healing or in H. pylori eradication. Both lansoprazole and omeprazole are well tolerated, but with mild adverse effects.
