Summary Background Studies to date have not directly compared the pharmacodynamic efficacies of different proton pump inhibitors in controlling intragastric acidity in patients treated with non‐steroidal anti‐inflammatory drugs. Aim To compare acid suppression with once‐daily esomeprazole 40 mg, lansoprazole 30 mg and pantoprazole 40 mg in patients receiving non‐selective or cyclo‐oxygenase‐2–selective non‐steroidal anti‐inflammatory drug therapy. Methods In this multicentre, open‐label, comparative, three‐way crossover study, adult patients ( n = 90) receiving non‐steroidal anti‐inflammatory drugs were randomized to one of six treatment sequences. At the study site, patients were administered esomeprazole 40 mg, lansoprazole 30 mg and pantoprazole 40 mg for 5 days each, with a washout period of ≥10 days between each treatment. Twenty‐four–hour pH testing was performed on day 5 of each dosing period. Results The mean percentage of time during the 24‐h pH monitoring period that gastric pH was >4.0 was significantly greater with esomeprazole (74.2%) compared with lansoprazole (66.5%; P < 0.001) and pantoprazole (60.8%; P < 0.001), and significantly greater with esomeprazole ( P < 0.05) than with the comparators regardless of whether using non‐selective vs. cyclo‐oxygenase‐2–selective non‐steroidal anti‐inflammatory drugs. Conclusions At the doses studied, esomeprazole treatment provides significantly greater gastric acid suppression than lansoprazole or pantoprazole in patients receiving non‐selective or cyclo‐oxygenase‐2–selective non‐steroidal anti‐inflammatory drugs.
