BACKGROUND:Gastro-oesophageal reflux disease (GERD) patients on proton pump inhibitors before breakfast or dinner have acid recovery at night. Bedtime immediate-release omeprazole (IR-OME) demonstrated better control of nocturnal pH than pantoprazole before dinner. AIM: To compare repeated once daily bedtime dosing of IR-OME, lansoprazole and esomeprazole on nocturnal gastric acidity. METHODS: Open-label, randomized, crossover study enrolling 54 patients with nocturnal GERD symptoms comparingIR-OME, lansoprazole and esomeprazole at steady state for nocturnal acid breakthrough (NAB), percentage of time with gastric pH > 4 and median gastric pH. RESULTS: Onset of nocturnal acid control with IR-OME was rapid. During the first half of the night, percentage of time with gastric pH > 4 and median gastric pH were significantly higher after IR-OME compared to esomeprazole or lansoprazole (P < 0.001, both comparisons). Over the 8-h night-time period, acid control with IR-OME was significantly better than lansoprazole (P < 0.001), and comparable to esomeprazole. IR-OME reduced NAB compared with esomeprazole and lansoprazole (61% vs. 92% and 92%; P < 0.001, both comparisons). CONCLUSIONS: Bedtime IR-OME provided more rapid control of night-time gastric pH and decreased NAB compared with esomeprazole and lansoprazole. Nocturnal acid control with IR-OME was superior to lansoprazole and comparable to esomeprazole. Bedtime dosing with IR-OME may be effective for patients with night-time heartburn.
