Comparative Analysis of the Efficiency and Safety of Pantoprazole, Omeprazole and Rabeprazole In Patient Care: A Systematic Review of Clinical Trials and Pharmacological Studies

Background: Proton pump inhibitors (PPIs) represent the most effective class of acid-suppressive medications, with pantoprazole, omeprazole and rabeprazole being among the most commonly prescribed. Despite their widespread use, comparative effectiveness and safety profiles require systematic evaluation. Objective: To conduct a comprehensive systematic review comparing the efficiency and safety of pantoprazole, omeprazole, and rabeprazole in various clinical conditions based on available clinical trials and pharmacological studies. Methods: A systematic literature search was conducted across PubMed, Cochrane Library, and EMBASE databases for studies published between 2010-2024. Inclusion criteria encompassed randomized controlled trials, comparative studies, and pharmacological analyses comparing at least two of the three PPIs. Primary outcomes included healing rates for peptic ulcers and gastroesophageal reflux disease (GERD), while secondary outcomes focused on adverse events and drug interactions. Results: Seventy-three studies met inclusion criteria, representing 15,847 patients across various indications. All three PPIs demonstrated comparable efficacy in healing peptic ulcers (85-92% healing rates at 4-8 weeks) and managing GERD symptoms (78-85% symptom resolution). Pantoprazole showed superior stability in acidic environments and reduced drug interaction potential. Omeprazole demonstrated the most extensive clinical experience but higher interaction risks with CYP2C19 substrates. Rabeprazole exhibited faster onset of action and consistent efficacy across CYP2C19 genotypes. Conclusions: While all three PPIs show similar therapeutic efficacy, important differences exist in pharmacokinetic properties, drug interactions, and specific clinical scenarios. Selection should be individualized based on patient-specific factors, comedications, and clinical context.
