| Abstract: | Aliment Pharmacol Ther 2010; 32: 182–190 Summary Background Nighttime heartburn, common among patients with gastro‐oesophageal reflux disease (GERD), is associated with substantial clinical effects. GERD‐related sleep disturbances are underappreciated and undertreated. Aim To evaluate the efficacy of esomeprazole on GERD‐related nighttime heartburn and associated sleep disturbances. Methods In this multicentre, randomized, double‐blind, placebo‐controlled study, patients with moderate‐to‐severe nighttime heartburn and GERD‐related sleep disturbances (endoscopies not required) received esomeprazole 20 mg or placebo each morning for 4 weeks. Heartburn symptoms and GERD‐related sleep disturbances were evaluated using the validated Pittsburgh Sleep Quality Index and validated Work Productivity and Activity Impairment Questionnaire. Results The analysis included 262 patients (esomeprazole, n = 137; placebo, n = 125). Significantly more patients receiving esomeprazole achieved nighttime heartburn relief (primary end point) than those receiving placebo (34.3% vs. 10.4%; P < 0.0001). Secondary end points such as relief of GERD‐related sleep disturbances (P = 0.006), days without GERD‐related sleep disturbances (P = 0.0003) and complete resolution of sleep disturbances (P < 0.0001) favoured esomeprazole over placebo. Sleep quality, work productivity and regular daily activities also improved significantly with esomeprazole vs. placebo. Conclusions Esomeprazole 20 mg is effective for patients with moderate‐to‐severe nighttime heartburn and GERD‐related sleep disturbances, improving heartburn symptoms, sleep quality, work productivity and functionality. |
