Similar Efficacy of Proton-Pump Inhibitors vs H2-Receptor Antagonists in Reducing Risk of Upper Gastrointestinal Bleeding or Ulcers in High-risk Users of Low-dose Aspirin

It is not clear whether H2-receptor antagonists (H2RAs) reduce the risk of gastrointestinal (GI) bleeding in aspirin users at high risk. We performed a double-blind randomized trial to compare the effects of a proton pump inhibitor (PPI) vs a H2RA antagonist in preventing recurrent upper gastrointestinal (GI) bleeding and ulcers in high-risk aspirin users.
