The effectiveness of esomeprazole 40 mg in patients with persistent symptoms of gastro-oesophageal reflux disease following treatment with a full dose proton pump inhibitor

BACKGROUND Some patients with gastro-oesophageal reflux disease (GORD) remain symptomatic despite proton pump inhibitor (PPI) treatment. There is a need to determine the most appropriate management of these patients. AIMS To assess the effectiveness of esomeprazole 40 mg in GORD symptoms persisting in patients receiving a full daily dose PPI. METHODS In this multi-centre open label study patients who had received full daily dose PPI for 8 weeks, but were still experiencing persistent GORD symptoms, were treated with esomeprazole 40 mg for 8 weeks (n = 99). The primary outcome variable was the change in the frequency of heartburn. Patient-reported outcomes were also assessed using the Reflux Disease Questionnaire (RDQ) and the GORD Impact Scale (GIS). RESULTS The mean frequency of heartburn was reduced by 78% from 4.4 days a week to 1 day a week at the end of the 8-week treatment period (p < 0.0001). Other GORD symptoms were also significantly reduced following of treatment with esomeprazole (all p < 0.0001). All RDQ dimensions and the level of symptom control as measured by the GIS also showed significant improvement at 8 weeks. CONCLUSIONS In patients with persistent GORD symptoms despite full dose daily PPI therapy, esomeprazole 40 mg significantly improved the frequency and severity of all GORD symptoms.
