Two weeks treatment with amoxicillin/omeprazole for eradication of Helicobacter pylori.

In an open study, 62 patients with Helicobacter pylori-associated ulcer disease or functional dyspepsia were treated for two weeks with 2 x 20 mg omeprazole preprandially and 4 x 500 mg amoxicillin suspension one hour before meals and at night. 57 patients (active ulcer disease: n = 53, functional dyspepsia: n = 4) completed the study without contravening the protocol. The rate of eradication of the bacteria at least 4 weeks after cessation of study medication was 82.5% (47/57 patients). Three patients experienced side effects during the treatment period (stomatitis, self-limiting diarrhea, allergic exanthema). In one case allergic exanthema led to discontinuation of therapy. 11 patients with H. pylori-associated ulcer disease received 2 x 20 mg omeprazole for two weeks. In this group no eradication of bacteria was observed.
