title: Review article: esomeprazole in the treatment of Helicobacter pylori.
abstract: Proton pump inhibitor-based triple therapy is the most commonly used treatment for eradication of Helicobacter pylori, with pooled eradication rates of approximately 90%. In the USA, per protocol eradication rates with 10-day proton pump inhibitor-based triple therapy are approximately 85%. Esomeprazole, a new proton pump inhibitor that is the S-isomer of omeprazole and produces a greater inhibition of acid secretion than omeprazole, has recently been evaluated in the treatment of H. pylori. Seven-day twice daily triple therapy with esomeprazole 20 mg, amoxicillin 1 g and clarithromycin 500 mg provided intention-to-treat eradication rates of 86-90% and per protocol eradication rates of 90-91% in duodenal ulcer patients in Europe and Canada. Ten-day triple therapy with esomeprazole 40 mg q.d.s., amoxicillin 1 g b.d. and clarithromycin 500 mg b.d. achieved intention-to-treat eradication rates of 77-78% and per protocol eradication rates of 84-85% in USA duodenal ulcer patients. Thus, esomeprazole triple therapy with amoxicillin and clarithromycin is effective in the treatment of H. pylori, with eradication rates comparable to previously studied proton pump inhibitor-based triple therapies.
