BACKGROUND: Several studies have demonstrated that night-time gastro-oesophageal reflux affects sleep quality, and thereby impairs daytime functioning. AIM: To determine whether treatment with a proton-pump inhibitor (rabeprazole) would improve both objective and subjective measures of sleep. METHODS: Individuals with complaints of significant gastro-oesophageal reflux disease were studied by polysomnography and 24-h pH monitoring on two separate nights. On one occasion, participants received 20 mg rabeprazole b.d., and on another they received placebo. Both study conditions were preceded by a week of treatment with either rabeprazole or placebo. The order of treatments was randomized. RESULTS: Rabeprazole significantly reduced overall acid reflux, but it did not significantly reduce night-time acid contact. Rabeprazole treatment significantly improved subjective indices of sleep quality. There were no significant differences on objective measures of sleep between placebo and rabeprazole treatment. CONCLUSIONS: Consistent with other studies of pharmacological treatments for gastro-oesophageal reflux, subjective measures of sleep improved with heartburn medication but objective measures were not affected.
