Potassium-competitive acid blockers offer a novel approach with improved pharmacokinetic and pharmacodynamic properties, enhancing acid suppression and clinical efficacy in acid-related disease management. This narrative review evaluates the role of potassium-competitive acid blockersin acid-related disease management, comparing the pharmacokinetic, pharmacodynamic, clinical efficacy, and safety profiles of currently available agents. A comprehensive literature search from January 2002 to June 2024 was conducted across multiple databases to gather data on the efficacy and safety of potassium-competitive acid blockers. Potassium-competitive acid blockers showed comparable or superior clinical efficacy and generally comparable safety in various clinical settings vs. comparator proton pump inhibitors, particularly in managing erosive esophagitis, H. pylori eradication, and peptic ulcer disease. Potassium-competitive acid blockers, of which vonoprazanis the most well studied, offer comparable or improved therapeutic outcomes over traditional proton pump inhibitors, making them a valid option for several acid-related disease indications.  \nKEYWORDS  \npotassium-competitive acid blockers, gastroesophageal reflux disease, Helicobacter pylori eradication, peptic ulcer disease, narrative review  \n1 Introduction  \nAcid-related diseases (ARDs), which include gastroesophageal reflux disease (GERD), peptic ulcer disease (PUD), and Helicobacter pylori infections, continue to be a major healthcare concern despite advances in management strategies (Inatomi et al., 2016) . ARD management primarily involves gastric acid suppression, with current options including proton pump inhibitors (PPIs) that covalently and irreversibly bind to H+ -K+ -ATPase (Oshima and Miwa, 2018) . PPIs have been available for more than 30 years and are considered the cornerstone treatment for patients with ARDs (Turshudzhyan et al., 2022) . However, PPIs: 1) only bind to active proton pumps, 2) have a short half-life, 3) are  \nFrontiers in Physiology 01 [frontiersin.org](frontiersin.org)  \ni","cbCail6uWKEl6Uhu","https://ap.wps.com/l/cbCail6uWKEl6Uhu","pdf",960144,11,"English","# Introduction\n## Acid-related diseases and the role of acid suppression\n## Limitations of proton pump inhibitors\n## Rationale for potassium-competitive acid blockers","[{\"question\":\"What problem with traditional proton pump inhibitor therapy is highlighted?\",\"answer\":\"Proton pump inhibitors may fail to maintain sufficiently prolonged intragastric pH for mucosal healing and effective H. pylori eradication, influenced by factors such as active-pump binding, short half-life, food effects, slow onset, and interindividual pharmacokinetic variability.\"},{\"question\":\"How do potassium-competitive acid blockers work differently from PPIs?\",\"answer\":\"Potassium-competitive acid blockers bind to the K+ site of H+/K+ ATPase, forming non-covalent and reversible bonds and competitively binding in both active and inactive proton pumps, leading to improved acid suppression characteristics.\"},{\"question\":\"What evidence did the review use to compare effectiveness and safety?\",\"answer\":\"A comprehensive literature search was conducted from January 2002 to June 2024 across multiple databases, evaluating pharmacokinetic, pharmacodynamic, clinical efficacy, and safety profiles versus comparator proton pump inhibitors.\"}]","Potassium-competitive acid blockers and advances in the management of patients with acid-related diseases - a narrative review | PDF",1790600440,28]
