[Short-term therapy with high dosage omeprazole and amoxicillin for Helicobacter pylori eradication. A pilot study]

Abstract

In an open study, 50 patients with Helicobacter pylori-associated ulcer disease or severe functional dyspepsia were treated over one week with 2 x 40 mg omeprazole in the morning and evening preprandially and 4 x 500 mg amoxicillin suspension one hour before meals and at night. Fourty-seven patients (ulcer disease: n = 40, functional dyspepsia: n = 7) completed the study without contravening the protocol. The proportion of Helicobacter pylori eradication four weeks after cessation of study medication was 61.7% (29/47 patients) as judged from negative biopsy urease test, specific culture and histology after modified Giemsa staining. Three patients experienced side effects (stomatitis, self-limiting diarrhea, allergic exanthema).
