Eradication of Helicobacter pylori with lansoprazole based triple therapy in peptic ulcer disease.

Lansoprazole 30 mg, amoxicillin 1000 mg, and tinidazole 500 mg were given twice daily to 39 peptic ulcer patients (26 duodenal and 13 gastric ulcer, mean age 52.4 +/- 15.01) who had H. pylori infection for two weeks. Additional lansoprazole 30 mg daily was given to duodenal and gastric ulcer patients for another two and six weeks respectively. Follow-up gastroduodenoscope was performed at fourth and eighth week and eighth and twelfth week for all duodenal and gastric ulcer patients, respectively. H. pylori status was evaluated by rapid urease test (CLO test) and histology at first and last endoscope. The ulcers were healed at the last endoscopy in 11 (85%) gastric ulcer patients and 24 (92%) duodenal ulcers patients. H. pylori infection was eradicated in 31 patients (79%). Mild side effects were observed in 15 per cent. In conclusion, 2 week regimen of lansoprazole, amoxicillin, and tinidazole triple therapy resulted in a relatively high healing rate of peptic ulcer (90%) and an acceptable eradication rate of H. pylori infection (79%).
