Suppression of Helicobacter pylori colonization with omeprazole

The efficacy of omeprazole, 20 mg once daily, in suppressing Helicobacter pylori colonization was studied in 33 patients with peptic ulcers. Omeprazole treatment produced a significant fall in the number of H. pylori colony-forming units in the antrum. This finding, together with the results of a meta-analysis of clinical trials of H. pylori eradication therapy, suggests that combinations of omeprazole and antibiotics may be useful as eradication therapy in patients with peptic ulcer disease and H. pylori infection.
