Comparison of Oral versus Intravenous Proton Pump Inhibitors in Preventing Re-bleeding from Peptic Ulcer after Successful Endoscopic Therapy.

Introduction Perforation, obstruction, and bleeding remain the most frequently encountered complications of peptic ulcer disease (PUD). Bleeding may be in the form of hematemesis or melena. The treatment of choice in patients with a bleeding peptic ulcer is endoscopic ligation to maintain the hemostatic balance followed by the administration of proton pump inhibitors (PPIs). This study focuses on the evaluation and comparison of intravenous (IV) and oral PPIs in terms of prevention of re-bleeding after successful endoscopy for peptic ulcers. Methods A prospective, comparative study was conducted in a tertiary care hospital in Pakistan from January 1, 2018 to June 30, 2019. The trial included known cases of PUD admitted with active upper gastrointestinal bleeding (UGIB). They were randomly divided into two groups: one received oral pantoprazole and the other was administered IV pantoprazole. The outcomes for both groups were compared. Data was entered and analyzed using Statistical Package for the Social Sciences (SPSS) software version 23.0 (IBM, Armonk, NY) Results There were 96 (48%) patients in the IV pantoprazole group and 104 (52%) in the oral group. From 24 hours after the medication onwards, the IV pantoprazole group showed a significant improvement in hemoglobin (Hb) levels (p: 0.01); the group also showed improvement in supine systolic BP at 48 hours (p: 0.04) and in diastolic BP at both 12 and 48 hours as compared to the oral pantoprazole group (p: 0.05). The mean duration of hospital stay, need for blood transfusion and repeat endoscopy, re-bleeding, and mortality rates were similar for both groups (p: >0.05). Conclusion We could not find any statistically significant difference between oral and IV routes of pantoprazole administration in the prevention of rebleeding when used after successful therapeutic endoscopy in patients with bleeding PUDs.
