Esomeprazole (Nexium(R)) is a new proton pump inhibitor that provides more effective acid control compared with other proton pump inhibitors. In patients with gastroesophageal reflux disease, standard doses of esomeprazole maintain intragastric pH above 4 for significantly longer periods compared with standard doses of other proton pump inhibitors after 5 days of treatment. Esomeprazole is approved for the treatment of symptomatic gastroesophageal reflux disease, the healing of erosive esophagitis, and maintenance of healing. In clinical trials, esomeprazole 40 mg once daily for up to 8 weeks provided higher rates of healing of erosive esophagitis and a greater proportion of patients with sustained resolution of heartburn, than either omeprazole 20 mg or lansoprazole 30 mg once daily. For the maintenance of healing, esomeprazole 20 mg once daily provided significantly higher rates of maintained healing of erosive esophagitis after 6 months of treatment compared with lansoprazole 15 mg once daily. Esomeprazole is also approved for use as part of a triple-drug therapy regimen in combination with amoxicillin and clarithromycin for the eradication of Helicobacter pylori in patients with duodenal ulcer disease. The side effect profile of esomeprazole is similar to that of omeprazole. Many patients with acid-related disorders may benefit from the more rapid symptom relief, higher rates of healing of erosive esophagitis, and improved maintenance of healing that can be achieved with esomeprazole.
