We. They're effective medications for treating gastroesophageal reflux disease (GERD). Department of Medicine, Michael E. DeBakey VA Medical Center, Baylor College of Medicine, Houston, Texas. NOTE. The fact sheets summarize the indications, treatment guidelines, and adverse reactions and risks of each drug class. Decreasing oesophageal acid exposure in patients with GERD: a comparison of rabeprazole and omeprazole, Intra-oesophageal pH profiles and pharmacokinetics of pantoprazole and esomeprazole: a crossover study in patients with gastro-oesophageal reflux disease. In the majority of studies, pH4times were presented as medians. Currently, five PPIs are available on the market: omeprazole, lansoprazole, rabeprazole, pantoprazole, and esomeprazole. Ngamruengphong S, Leontiadis GI, Radhi S, Dentino A, Nugent K. Proton pump inhibitors and risk of fracture: a systematic review and meta-analysis of observational studies. They can also cause long-term problems like weakening bones and kidney issues. The results of our review suggest that increasing dosing frequency to twice daily may be a more effective strategy than escalating once-a-day dosing (Figure 3). Omeprazole and lansoprazole (30 mg) and 20 mg of esomeprazole rabeprazole are functionally equivalent. Upper gastrointestinal (UGI) bleeding due to PUD is an important emergency medical condition which results in very high patient morbidity, health care costs, and mortality.29,30 While rapid assessment, best supportive care, and prompt endoscopic diagnosis and hemostasis are the mainstays of modern societal recommendations,3032 the method and dose of antisecretory PPI therapy remains an important consideration. They also may be packaged in combination with bicarbonate to confer temporary luminal pH neutralization. Williams MP, Sercombe J, Hamilton MI, et al. Systematic review: proton-pump inhibitor failure in gastro-oesophageal reflux disease--where next? bid, twice daily; tid, 3 times/d. The regression line for twice-daily and 3 times/d administration superimpose each other. Table 3 provides information regarding PPI potency in relation to cost. Katschinski B, Logan R, Davies J, Faulkner G, Pearson J, Lang-man M. Prognostic factors in upper gastrointestinal bleeding. May increase to 1 mg/kg twice daily if needed for symptomatic improvement. Primary-care physicians perceptions and practices on the management of GERD: results of a national survey. Maintenance: 20 mg once daily. It works by decreasing the amount of acid produced by the stomach. Table 3 provides the US costs of different PPIs in standard tablet or capsule formulations by strength. Metz DC, Inadomi JM, Howden CW, van Zanten SJ, Bytzer P. On-demand therapy for gastroesophageal reflux disease. 4 UNI | 4.95 per 1UNI. Kirchheiner et al17 reported the relative potencies were 0.23, 0.90, 1.00, 1.60, and 1.82 for pantoprazole, lansoprazole, omeprazole, esomeprazole, and rabeprazole, respectively (ie, 40 mg of pantoprazole and 9 mg of omeprazole were similarly effective when assessed by pH4time) (Table 1). This article attempts to clarify the obfuscation surrounding PPI dosing for tailored acid suppression. Retrospective observational studies and their meta-analyses have also demonstrated a potential link between the use of PPIs and the development of community acquired pneumonia.89,90 A meta-analysis which included eight observational studies suggested that PPI use was associated with an 27% increased risk for either hospital or community acquired pneumonia (OR, 1.27) but that the greatest risk was within 7 days of beginning PPI treatment (OR, 3.95).89 This early risk had been demonstrated elsewhere91 and is interesting in that the outcome occurs before PPIs attain their full effectiveness. Write a review. Stanghellini V, Frisoni C. Editorial: reflux, dyspepsia, and Rome III (or Rome IV?). government site. Twenty-five percent of the drug dose is liberated in the proximal small intestine at a pH of 5.5, with pharmacokinetics (peak plasma concentration of 1 to 2 hours) similar to traditional enteric coated PPIs. Katz PO, Gerson LB, Vela MF. A meta-analysis of 112 individual RCTs by Koch et al.52 suggested that H2RAs demonstrated no evidence supporting the use of conventional dose H2RAs in a prophylactic role although high dose H2RAs may be beneficial.53 Once daily PPIs, on the other hand, were protective against the development of gastroduodenal ulcers (OR=0.35) in asymptomatic patients taking low-dose aspirin who underwent endoscopy.54, The best data in favor of PPI use come from two multicenter trials of higher-risk patients (n=1,429) taking daily NSAIDs. Although all members in this class act in a similar fashion, inhibiting active parietal cell acid secretion, there are slight differences among PPIs relating to their pharmacokinetic properties, metabolism, and Food and Drug Administration (FDA)-approved clinical indications. The results of two double-blind studies. Evaluation of omeprazole, lansoprazole, pantoprazole, and rabeprazole in the treatment of acid-related diseases. The .gov means its official. A placebo-controlled trial to assess the effects of 8 days of dosing with rabeprazole versus omeprazole on 24-h intragastric acidity and plasma gastrin concentrations in young healthy male subjects. As of January 3, 2006, the PPI on the Cleveland Clinic Formulary for adult patients who do not require a suspension is esomeprazole (Nexium). and transmitted securely. OE, omeprazole equivalent; PPIs, proton pump inhibitors. Janczewska I, Sagar M, Sjostedt S, et al. Pantoprazole 20 mg was equivalent to 4.5 mg of omeprazole. This physiology is the rationale both for preprandial dosing (important due to short serum half-life) and the observation of escalating pharmacologic efficacy of PPIs after multiday treatment.10, PPIs are highly protein bound and subject to degradation by hepatic P450 cytochromes. Whether these approaches offer a clear clinical advantage or carry with them unanticipated problems, remains to be determined. ACCF/ACG/AHA 2008 Expert Consensus document on reducing the gastrointestinal risks of antiplatelet therapy and NSAID use: a report of the American College of Cardiology Foundation Task Force on Clinical Expert Consensus documents. Comparison of the effectiveness of various PPIs in maintaining the median pH at 6 or higher for 24 hours (pH6time) when given once, twice, or 3 times daily (Supplementary Table 4 for details).

This is an Open Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License (, Proton pump inhibitors, Review, Pharmacokinetics, Indications, Risk, {"type":"clinical-trial","attrs":{"text":"NCT01059383","term_id":"NCT01059383"}}. Overall, we confirmed that PPIs differ in potency in terms of acid suppression as assessed by pH4time. PPIs often are prescribed for long periods. Approximately half of patients do not take their PPIs within 1 hour of breakfast79,82 and they may not have been instructed to do so by their physician or pharmacist.84 Poor compliance, combined with a narrow window to provide efficacy due to plasma half-life, may be an important cause of PPI failure.78. Review article: the clinical pharmacology of proton pump inhibitors. Double blind comparison of omeprazole (40 mg od) versus cimetidine (400 mg qd) in the treatment of symptomatic erosive reflux oesophagitis, assessed endoscopically, histologically and by 24 h pH monitoring. Famotidine for the prevention of gastric and duodenal ulcers caused by nonsteroidal antiinflammatory drugs. The current address for Aylin Tansel is 114 Doughty Street, Suite 249 MSC 702, Charleston, South Carolina 29425. Endoscopic experience improves interobserver agreement in the grading of esophagitis by Los Angeles classification: conventional endoscopy and optimal band image system. We manually searched bibliographies of relevant articles for references not captured by the search strategy. Full or standard dose. We also provide estimates for both dexlansoprazole and the newest PPI, the potassium-competitive acid blocker vonoprazan. Eriksson S, Lngstrm G, Rikner L, Carlsson R, Naesdal J. Omeprazole and H2-receptor antagonists in the acute treatment of duodenal ulcer, gastric ulcer and reflux oesophagitis: a meta-analysis. This increase in half-life correspondingly increases the area under the plasma concentration curve (AUC) by over 20-fold, representing increased tissue exposure and thus duration of effect at the parietal cell cannaliculus.9799 While definitive trials of clinical efficacy are still unavailable, this revision to the structure of PPIs has intriguing future potential. Lansoprazole 15 mg was equivalent to 13.5 mg of omeprazole. Dual-release dexlansoprazole is formulated to release drug in two separate pH controlled phases. ); and by Public Health Service grant 5T32DK08326607 (A.T.). In 2004, when the original guideline was developed (CG17), doses of proton pump inhibitors (PPIs) were based on the British National Formulary (BNF) at the time, as in table 1 below. Purpose: The German annual drug prescription-report has indicated overuse of proton pump inhibitors (PPIs) for many years; however, little was known about the characteristics of people using PPIs. HHS Vulnerability Disclosure, Help Using twice-daily PPIs is more effective in increasing efficacy increasing once-daily PPI dosage. We compared values for each PPI regimen as weighted and unweighted medians and means. Increasing the frequency to twice-daily PPI increased pH4time linearly, from approximately 15.8 to 21.0 hours. Changes of gastric mucosal architecture during long-term omeprazole therapy: results of a randomized clinical trial. Increasing the dosing interval to 3 times/d (5 studies, 106 subjects) did not provide any further improvement (the 3 times/d regression was superimposed on the twice-daily regression) (Figure 2B). The caveat to that statement is that there were only a few studies with small sample sizes using 3 times/d dosing. This is especially important for studies that are not double-blinded, which can be subject to higher degrees of bias in qualitative assessments such as symptom improvement. Sarkar M, Hennessy S, Yang YX. Since their introduction approximately 3 decades ago, proton pump inhibitors (PPIs) have become one of the most widely used drugs worldwide. Lanza F, Goff J, Silvers D, et al. Here, we used the relative potencies reported by Kirchheiner et al17 to compare available PPIs in terms of OEs in relation to dosepH time. Omeprazole. Table 1 shows the recommended doses of proton pump inhibitors (PPIs) for the management of people with gastro-oesophageal reflux disease (GORD) and severe oesophagitis. We examined whether the results differed significantly if we used median or mean results for the time the pH was equal to or greater than a designated pH level (eg, pH4time using several methods). Food and Drug Administration Approved Indications for Proton Pump Inhibitors. Changing patterns of Helicobacter pylori gastritis in long-standing acid suppression. Omeprazole is a proton pump inhibitor (PPI). WHAT ARE PPIs AND HOW DO THEY WORK? A number of efforts have been made to overcome the inherent pharmacologic limitations of currently available PPIs, in particular their short plasma half-life (and therefore short duration of effect) and the need for preprandial dosing. Vonoprazan, a new class of PPI (potassium competitive-acid blocker), is both long acting and does not require acid activation.34 Although most pH data come from Asian populations, 2 studies examined the effects of vonoprazan in a Western (UK) population.35,36 Of these, only 1 study met our criteria examining effects of vonoprazan in a Western population.37 The weighted median pH4time was 60.2%, 85.2%, 90.1%, and 93.2% for 10, 20, 30, and 40 mg of vonoprazan, respectively, when given once daily after 7 days of therapy.37 Based on the PPI pH4time plots (Figures 1 and and2A),2A), when given once daily, 10 mg of vonoprazan was equivalent to 60 mg OE once daily, and 20 mg was equal to 60 mg OE twice daily (Supplementary Table 3). Cost is also an important consideration. Though not yet approved for clinical use, this new subset of PPI with a prolonged half-life may ultimately offer advantages over its benzimidazole cousins.10, PPIs are membrane permeable, acid-labile weak bases. Acid-related disorders and use of antisecretory medication.

Recently, the prevalence of PPI use was estimated at 7% to 9% in ambulatory patients,1,2 and more than 20% among ambulatory patients older than 80 years.2 Increased PPI use results in high health care costs, exaggerated further by the use of proprietary rather than generic PPIs.3 It has been estimated that 5-year excess costs associated with proprietary PPIs exceeded $47 billion dollars in the United States.3, The relative potency of different histamine-2receptor antagonists (H2RAs) was based historically on healing rates of peptic ulcers in which the duration of the intragastric pH level of 3 or higher was a reliable surrogate marker for the relative effectiveness of H2RAs.4,5 PPIs largely have replaced H2RAs because they proved to be more effective for ulcer healing and relieving symptoms and healing of erosive gastroesophageal reflux disease (GERD) than H2RAs.69 Analyses of the relationship between PPI effectiveness and intragastric pH level also showed the duration the pH level was maintained at a pH of 4 or greater over the 24-hour day (pH4time) could be used as a surrogate marker for symptom relief in GERD, and in the healing and prevention of relapse of erosive esophagitis.6 The pH4time biomarker subsequently has been used widely to compare antisecretory drugs, especially in marketing studies designed to prove the superiority of one PPI over another.1014 PPIs also have proven to be useful adjuvants to antimicrobial therapy for Helicobacter pylori infection.15.
