Despite recommendations from clinical practice guidelines to discharge patients from the hospital on once daily proton pump inhibitors after acute management of UGIB, clinical practice is to use twice daily proton pump inhibitor therapy. The objective of this study will be to assess whether or not once daily pantoprazole is non-inferior to twice daily pantoprazole in ulcer healing with a dose of once daily versus twice daily proton-pump inhibitor following an upper gastrointestinal bleed. Additionally, this study will observe for any potential difference in safety for once daily versus twice daily proton pump inhibitors.
