Oral Versus IV Proton Pump Inhibitor in High-risk Bleeding Peptic Ulcers After Endoscopic Hemostasis

Phase 3

• Conditions: Peptic Ulcers
• Interventions: Drug: Lansoprazole (Takepron OD); Drug: Pantoprazole (Pantoloc)

• Registration Number: NCT01182597
• Lead Sponsor: National Taiwan University Hospital

Brief Summary

Endoscopic hemostasis has been documented by a number of clinical studies to be effective in decreasing rebleeding, need for emergency surgery, and hospitalization days. Studies showed adjuvant treatment with proton pump inhibitor (PPI) after initial endoscopic hemostasis reduced recurrent ulcer bleeding. However, the optimal dose and route of adjuvant PPI therapy remains controversial. A recent study demonstrated frequent oral PPI offered similar acid control as currently recommended intravenous infusion PPI did in patients with bleeding ulcers. The investigators hypothesize that an frequent oral PPI treatment has similar benefit as proton pump inhibitor infusion in patient with bleeding ulcers after combined endoscopic hemostasis.

Detailed Description

Acute peptic ulcer bleeding remains a therapeutic challenge with significant morbidity and mortality. Endoscopic therapy using various modalities significantly reduces re-bleeding, need for surgery and mortality in patients with peptic ulcer bleeding. Endoscopic therapy achieves successful hemostasis in more than 90% of patients, and re-bleeding occurs in 10-30% of patients. Re-bleeding has an important impact on prognosis. Studies showed adjuvant treatment with proton pump inhibitor (PPI) after initial endoscopic hemostasis reduced recurrent ulcer bleeding. Two consensus documents have endorsed a high-dose PPI regimen (80 mg stat followed by an infusion of 8 mg/h for 72 h). The biologically plausible mechanism of benefit of such a high-dose regimen is to promote clot stability by sustaining the intragastric pH above 6. However, the optimal dose and administration route of proton pump inhibitors (PPI) for the prevention of peptic ulcer rebleeding remains unclear.

The use of IV PPIs adds significantly to the cost of patient care in hospital. Recent studies reported oral PPI may have similar acid suppressive effect as high dose PPI infusion. A prospective trial and a retrospective analysis have shown that oral PPI therapy may also be effective in decreasing rebleeding rates in patients with acute gastrointestinal bleeding due to high-risk peptic ulcer disease, and the magnitude of benefit appears similar to what has been demonstrated with IV PPIs. A meta-analysis reported no difference in the magnitude of risk reduction between the oral- and the intravenous-route. Given the significant cost savings over their IV counterparts, oral PPIs would be an attractive choice of therapy in this situation provided that they have a similar efficacy to IV PPIs. However, no studies have directly compared oral and IV PPI therapy in this setting.

We conducted a head-to-head study, comparing two strategies for PPI administration in the prevention of rebleeding, surgery, and death in patients with high-risk bleeding peptic ulcers in whom successful endoscopic hemostasis was achieved.
