Objectives: Gastroesophageal reflux disease (GERD) is a chronic condition that usually requires long-term maintenance therapy with proton-pump inhibitors (PPIs). In clinical practice, patients receive PPIs at the lowest dose to control symptoms. However, it is not known whether this approach adequately controls acidic esophageal reflux. We sought to investigate the efficacy of three different dosages of esomeprazole in patients receiving maintenance therapy for GERD, using the Bravo pH system. Methods: Patients with a previous history of erosive esophagitis A or B (LA classification) that was healed at the time of enrollment or endoscopy-negative reflux disease (ENRD), documented with an abnormal pH study, were randomized to receive maintenance therapy with esomeprazole 40 mg twice daily (group A), once daily (group B), or every other day (group C). Intraesophageal pH was monitored for two consecutive days using the Bravo wireless system, 30 days after randomization. The parameters subjected to analysis were percent of total time pH4 and the De Meester score. Results: The pH results from 73 patients (group A24, group B24, group C25 patients) were subjected to final analysis. On the first day of the study, the mean (s.d.) percent of total time pH 4 and the De Meester score were group A: 0.9(1.2) and 4.1(4.0); group B: 1.5(1.6) and 7.0(6.9); group C: 1.3(1.0) and 6.0(3.3), respectively (P0.262 and 0.134, respectively). On the second day of the study, the corresponding values were group A: 0.7(1.0) and 3.9(5.9); group B: 1.5(1.8) and 6.4(6.6); group C: 7.0(4.4) and 29.4(19.4), respectively. The difference was statistically significant (P0.0001 and 0.0001, respectively). Further analysis showed that patients not receiving PPI had a significantly higher mean percent of total time pH4 and De Meester score as compared with patients on PPI once or twice daily (P0.001 and 0.001 respectively). Conclusions: The administration of esomeprazole 40 mg every other day does not control acidic esophageal reflux on the day off PPI. Esomeprazole 40 mg once daily effectively controls reflux of acid in patients with history of mild esophagitis or ENRD, whereas doubling the dose does not seem to confer any further advantage. © 2010 by the American College of Gastroenterology.
