Proton pump inhibitors are superior to placebo for the prevention of NSAID-induced gastric ulcers but are not superior to misoprostol, 800µg/day.
This was the conclusion of David Graham and colleagues from their double-blind multicentre, active and placebo-controlled study of 537 patients. All patients in the study were not positive for Helicobacter pylori, were long term users of NSAIDS and had a history of endoscopically documented gastric ulcer.
