Introduction: The infection by Helicobacter pylori, is associate with multiple complications: chronic gastritis, gastric and duodenal ulcer, gastric cancer and lymphoma type MALT. The levels of eradication and adherence with the standard therapy have declined progressively in the last years. The sequential modified therapy could be an alternative to improve his efficiency and the adherence to the treatment in view of the high current resistance to the clarithromycin. Aims: To compare the efficiency of the triple sequential standard therapy and the triple sequential therapy modified with levofloxacin for the eradication of Helicobacter pylori. Materials and Methods: 140 patients were studied by infection by Helicobacter pylori verified by gastric biopsy that they were assigned in randomized form in two groups of treatment: Group of sequential standard therapy with omeprazole and amoxicillin for 5 days, followed by omeprazole, clarithromycin and metronidazole for 5 additional days. Group of sequential therapy modified with omeprazole and amoxicillin for 5 days, followed by omeprazole, levofloxacin and metronidazole for 5 additional days. The eradication was confirmed by gastric biopsy later to the treatment. Was realized a questionnaire to evaluate the adherence and the side effects in every group. Results: 70 patients were evaluated in every group. The rate of eradication and suspension of treatment was 80% and 5,71 % respectively in the group of sequential modified therapy comparing with 65,71% and 11,42% in the group of sequential standard therapy, being statistically significant the differences in both cases (p <0,05). Conclusions: The sequential therapy modified with levofloxacin achieves major rates of eradication and of adherence to the treatment of the Helicobacter pylori when it is compared with the sequential standard therapy.
