PPI Infusion Versus Oral Acid Pump Inhibitors for Bleeding Peptic Ulcers

Vonoprazan (VPZ), an oral potassium-competitive acid blocker (P-CAB) has emerged as an alternative potent acid-suppressant.It has a faster onset of action in 1 day (3-5 days in PPI), and is more stable in acidic condition than PPI. While many studies compared Vonoprazan against PPI in the treatment of reflux oesophagitis, H. Pylori eradication, and gastric ulcers; thus far, there is a paucity of data on use of Vonoprazan on bleeding peptic ulcers. We perform a multicenter randomized controlled trial (RCT) to compare the efficacy of oral Vonoprazan against standard high dose PPI therapy in bleeding peptic ulcers that had received successful endoscopic haemostasis We hypothesize that in patients with bleeding peptic ulcers, the use of acid pump inhibitors Vonoprazan would not be inferior to standard treatment of a bolus plus high dose PPI intravenous infusion at preventing recurrent bleeding after endoscopic haemostasis.

Deprescribing Inappropriate Proton Pump Inhibitors

The DROPIT Trial is an interventional, open-labelled, cluster-randomized controlled trial conducted in the Swiss primary care setting. It aims to evaluate an intervention to guide the deprescribing of inappropriate proton-pump inhibitors (PPIs). Therefore, the trial investigates whether the study intervention leads to the deprescribing of inappropriate PPI prescription while ensuring noninferiority safety, in comparison to usual care. Additionally, the trail aims to investigate the intervention's impact on other clinical aspects, as well as addressing features of the implementation of the intervention and its cost-effectiveness.

Intestinal Microbiota After PPI Treatment

This clinical study aims to investigate the effects of short-term treatment with proton pump inhibitors (PPIs) on the gut microbiota of pediatric patients. PPIs are among the most frequently prescribed medications in children and adolescents for the management of acid-related disorders, such as gastroesophageal reflux disease (GERD). However, emerging evidence suggests that these medications may have unintended consequences on the delicate ecosystem of beneficial microorganisms residing in the human gastrointestinal tract. The intestinal microbiota plays a pivotal role in modulating immune responses, supporting nutrient metabolism, and maintaining the integrity of the gut barrier. Disruption of this microbial balance-known as dysbiosis-has been associated with several health conditions, including infections, allergies, obesity, and chronic inflammation. In adults, long-term PPI use has been linked to microbiota alterations, but data in the pediatric population remain limited and inconclusive. To address this gap, our prospective longitudinal study will recruit pediatric patients prescribed PPI therapy for clinical indications. Stool samples will be collected at four time points: prior to PPI administration, during treatment, and at two follow-up stages post-cessation. Using 16S rRNA gene sequencing, we will profile changes in microbial diversity and abundance over time. The results will offer insight into whether short-term PPI exposure in children leads to significant, lasting changes in gut microbiota composition or diversity. Such information may ultimately inform prescribing practices, support personalized therapeutic strategies, and help mitigate potential risks associated with microbiota disruption during childhood-a critical period for microbial and immune system development.

RAK-PRIDE: Optimizing Proton Pump Inhibitor Use Through Education and Intervention

The goal of this study is to determine if a pharmacist-led educational intervention can reduce the inappropriate use of proton pump inhibitors (PPIs) among adult patients (≥18 years) with potentially inappropriate PPI prescriptions in Ras Al Khaimah. The main questions it aims to answer are: * Can a pharmacist-led education program reduce unnecessary PPI use? * Does the intervention improve patients' quality of life and reduce healthcare costs? Researchers will compare the intervention group (receiving pharmacist-led education and materials) to the usual care group to see if the intervention reduces PPI use and improves patient outcomes. Participants will: * Receive educational materials from pharmacists, including a patient educational brochure, PPI patient decision aid, PPI deprescribing pamphlet, and PPI patient action plan. * Physicians involved will also receive a pharmaceutical intervention, which includes a physician educational brochure, PPI evidence-based deprescribing guideline, PPI deprescribing algorithm, and whiteboard videos on PPI deprescribing. * Patients will be followed up for 6 months to monitor changes in PPI use, symptoms, and quality of life.
