Background/AimsProton pump inhibitors have been widely used in recent years. However, there are studies suggesting that proton pump inhibitors may not control the gastric acidity effectively during the night, especially in gastroesophageal reflux disease. It has therefore been suggested that H2 receptor blockers should be added to the therapy. The aim of our study was to evaluate the effects of proton pump inhibitors alone or in combination with H2 receptor blockers on gastric acidity with 24-hour gastric pH monitoring.MethodsEsophagogastroscopy and 24-hour gastric pH monitoring were performed on 10 patients with dyspeptic symptoms. No patient had antacidity. All patients had erosive antral gastritis. Patients were randomized to two groups as either proton pump inhibitor therapy group (rabeprazole 20 mg/day, p.o.) or proton pump inhibitor + H2 receptor blocker therapy group (rabeprazole 20 mg/day, p.o. + famotidine 40 mg/day, p.o). After one month of treatment, 24-hour gastric pH monitoring was re-performed.ResultsSeven female and three male patients were enrolled into the study. The mean age was 51.1+/-11.56 years. All patients had antral erosive gastritis. Gastric pH was measured as less than 4 in 81.4% of the 24-hour period prior to rabeprazole treatment. With rabeprazole treatment this ratio decreased to 27.6% (p<0.05). These ratios were 86.3% and 4.55%, respectively, in the group that received combination therapy (p<0.05).ConclusionsCombination therapy with H2 receptor blockers and proton pump inhibitors seemed to control intra-gastric pH better than proton pump inhibitors alone. Use of H2 receptor blockers and proton pump inhibitors in combination to control intra-gastric pH is more beneficial.
