A placebo‐controlled trial to assess the effects of 8 days of dosing with rabeprazole versus omeprazole on 24‐h intragastric acidity and plasma gastrin concentrations in young healthy male subjects

Abstract

Rabeprazole 20 mg once daily has a significantly faster onset of antisecretory activity than omeprazole 20 mg once daily. After 8 days the differences in intragastric pH > 3 and > 4 holding times persisted, but there was no significant difference in 24-h acidity.
