The Effect of Dexlansoprazole on Gastroesophageal Reflux Disease: A Systematic Review and Meta-Analysis. Int J Mol Sci 2024; 25:1247. [PMID: 38279248 PMCID: PMC10816097 DOI: 10.3390/ijms25021247] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2023] [Revised: 01/16/2024] [Accepted: 01/17/2024] [Indexed: 01/28/2024] Open
Abstract
This systematic review and meta-analysis evaluated the efficacy of dexlansoprazole (a proton pump inhibitor-PPI) in resolving heartburn, reflux, and other symptoms and complications resulting from gastroesophageal reflux disease (GERD). The study followed PRISMA 2020 and was registered in PROSPERO (CRD42020206513). The search strategy used MeSH and free terms appropriately adapted for each database. Only randomized clinical trials (RCTs) were included. The Cochrane tool (RoB 2.0) was used to assess the risk of bias, and the certainty of evidence was rated using GRADE. Ten RCTs were included. Dexlansoprazole outperformed the placebo and other PPIs in the resolution of heartburn and reflux symptoms in patients with GERD, with benefits during and after treatment, especially in those with moderate and severe symptoms. The meta-analyses indicated that dexlansoprazole at doses of 30 and 60 mg had more 24 h heartburn-free days and nights compared to the placebo medications; no difference was reported between dexlansoprazole at doses of 30 and 60 mg in heartburn-free nights. A low bias risk and a moderate certainty of evidence were observed. This review confirms the therapeutic effect of dexlansoprazole (placebo-controlled) and its improvements in GERD symptoms compared to another PPI. However, the interpretation of the results should be carried out cautiously due to the small number of included studies and other reported limitations.

Abstract
Objectives: To develop novel dual release prototype capsule formulations of rabeprazole and evaluation of pharmacokinetic properties relative to the reference product (Aciphex®) in Beagle dogs. Methods: The dual release prototype formulations of rabeprazole were developed by preparing optimized mini-tablets core which was subsequently coated with barrier/enteric coating using standard excipients. Both novel prototype formulations were subjected for in vitro release and assay by HPLC-UV to assess long term stability. Single dose pharmacokinetic study used a single sequence three treatments crossover design. In Periods 1 and 2, four dogs received oral 20 mg dose of two prototype formulations. In Period 3, all dogs received a 20 mg oral dose of Aciphex® reference product. There was a 1-week washout time between two successive periods. A quantitative analysis of rabeprazole/sulfide metabolite in plasma samples was performed using a validated LC-MS/MS assay and PK parameters were estimated by non-compartmental analysis. Results: The stability of the prototype formulations was confirmed over a period of 24 months with an acceptable assay and dissolution data. One of the novel prototype formulations showed 70% oral bioavailability relative to the reference product. Despite a 30% reduced bioavailability, this showed 1 h delay in peak concentration, longer plasma residence time of rabeprazole (up to 12 h) and longer apparent elimination half-life. Conclusions: The use of a canine model has enabled the selection of a novel dual-release prototype formulation of rabeprazole for further clinical development.

Abstract
Although gastroesophageal reflux disease is not as common in Asia as in western countries, the prevalence has increased substantially during the past decade. Gastroesophageal reflux disease is associated with considerable reductions in subjective well-being and work productivity, as well as increased healthcare use. Proton pump inhibitors (PPIs) are currently the most effective treatment for gastroesophageal reflux disease. However, there are limitations associated with these drugs in terms of partial and non-response. Dexlansoprazole is the first PPI with a dual delayed release formulation designed to provide 2 separate releases of medication to extend the duration of effective plasma drug concentration. Dexlansoprazole has been shown to be effective for healing of erosive esophagitis, and to improve subjective well-being by controlling 24-hour symptoms. Dexlansoprazole has also been shown to achieve good plasma concentration regardless of administration with food, providing flexible dosing. Studies in healthy volunteers showed no clinically important effects on exposure to the active metabolite of clopidogrel or clopidogrel-induced platelet inhibition, with no dose adjustment of clopidogrel necessary when coprescribed. This review discusses the role of the new generation PPI, dexlansoprazole, in the treatment of gastroesophageal reflux disease in Asia.

Abstract
OBJECTIVE To evaluate the safety and pharmacokinetic profile of dexlansoprazole modified-release (MR) capsules in pediatric patients with symptomatic gastroesophageal reflux disease (GERD). METHODS This Phase I, open-label study enrolled male and female patients (1 to 11 years of age) with GERD. Patients received dexlansoprazole MR 15 mg, 30 mg, or 60 mg (according to weight) once daily for 7 days. Blood samples for the measurement of plasma dexlansoprazole concentrations were collected for 24 hours after the day 7 dose. Dexlansoprazole plasma concentrations and pharmacokinetic parameters were summarized by dose group. Safety assessments included adverse events (AEs), clinical laboratory evaluations, fasting gastrin concentrations, physical examinations, electrocardiograms, and vital signs. RESULTS Thirty-six patients received study drug (12 per dose group), and 31 had evaluable pharmacokinetic data. There was a significant effect of weight on dose-normalized area under the curve (AUC, P=0.003) and dose-normalized maximum plasma concentration (Cmax) (P=0.013), indicating that for a given dose, dexlansoprazole exposure decreases as body weight increases. After adjusting for body weight, both dexlansoprazole Cmax and AUC increased in an approximately dose-proportional manner with increasing dexlansoprazole dose. A total of ten of 36 patients reported at least one treatment-emergent AE, with most events considered mild in intensity. The most common AEs were vomiting, abdominal pain, diarrhea, and nausea. CONCLUSION In 1- to 11-year-old patients with symptomatic GERD, weight-adjusted dexlansoprazole AUC and Cmax increased approximately dose-proportionally. However, for a given dose, dexlansoprazole exposure decreased with increasing body weight. Dexlansoprazole MR was well tolerated, and the incidence of AEs did not increase with increasing dose.

Abstract
CONTEXT Helicobacter pylori has been associated with worsening of gastroesophageal reflux disease (GERD). OBJECTIVE To evaluate the effect of H. pylori eradication in GERD patients. METHODS We conducted a prospective, randomized, controlled trial performing symptom evaluation, endoscopy, histology, manometry and esophageal pH testing on GERD patients. Patients infected with H. pylori were randomized to: 1) eradication treatment plus proton pump inhibitors treatment, or 2) proton pump inhibitors alone. Patients not infected constituted a negative control group. After 3 months, patients were re-evaluated by symptom assessment, endoscopy, histology and manometry. RESULTS GERD treatment resulted in significantly higher lower esophageal sphincter pressure, as measured by mean expiratory pressure, in H. pylori negative patients. There was significantly lower proportion of hypotensive waves and significantly higher proportion of normotensive waves in non-eradicated patients. All symptom scores were significantly reduced in the post-treatment period compared to baseline, to values that were similar among the three groups, in the post-treatment period. In the post-treatment period, erosive esophagitis was significantly less frequent on those not eradicated. CONCLUSION Manometric, clinical and endoscopic data showed no benefit in eradicating H. pylori in GERD. Our data supports the hypothesis that H. pylori eradication does not influence GERD.

Abstract
OBJECTIVES Dexlansoprazole MR 30 mg once daily (QD) is approved in adults for the treatment of symptomatic nonerosive gastroesophageal reflux disease (GERD) and maintenance of healed erosive esophagitis (EE); 60 mg is approved for healing EE. The present study assesses the pharmacokinetic (PK) profile and safety of dexlansoprazole MR in adolescent patients. PATIENTS AND METHODS Phase 1, open-label, parallel-group, multicenter study in male and female adolescents (12-17 years) with GERD. Patients were randomized to receive dexlansoprazole MR (30 or 60 mg, QD) for 7 days. Blood samples to determine dexlansoprazole plasma concentrations were drawn over a 24-hour period after dosing on day 7. Dexlansoprazole plasma concentrations and PK parameters were summarized by dose group. Safety assessments included monitoring of adverse events (AEs). RESULTS Thirty-six patients (mean age 14.6 years), 14 boys and 22 girls, were randomized, with PK data available for 35 patients. The overall exposure of dexlansoprazole after administration of the 60-mg capsule was slightly less than double the exposure from the 30-mg capsule. Cmax (691 and 1136 ng/mL) and area under the plasma concentration time curve (2886 and 5120 ng · h/mL) values for the 30- and 60-mg doses, respectively, were similar to results from previous phase 1 studies in healthy adults. Twelve of 36 patients (33.3%) experienced a total of 21 treatment-emergent AEs. All of the AEs were considered to be of mild severity. CONCLUSIONS The PK data for dexlansoprazole MR 30- and 60-mg capsules in adolescent patients with symptomatic GERD were similar to those in healthy adults. Both doses were well tolerated.

Abstract
BACKGROUND Dexlansoprazole, the dextrorotatory enantiomer of lansoprazole, is a proton pump inhibitor (PPI) formulated to have dual delayed-release properties. It is indicated for healing all grades of esophagitis, maintaining the healing of erosive esophagitis (EE), and treating heartburn associated with nonerosive gastroesophageal reflux disease. OBJECTIVE This article reviews the pharmacology, pharmacokinetics, and pharmacodynamics of dexlansoprazole, as well as its clinical efficacy and tolerability. METHODS MEDLINE (1966-April 2010) and International Pharmaceutical Abstracts (1970-April 2010) were searched for original research and review articles published in English using the terms dexlansoprazole and TAK-390MR. The reference lists of identified articles were reviewed for additional pertinent publications. Abstracts from 2007-2009 American College of Gastroenterology and Digestive Disease Week meetings were searched using the same terms. RESULTS By irreversibly binding to H(+)K(+)-ATPase, dexlansoprazole inhibits acid production by the parietal cell. Its dual delayed-release formulation provides 2 distinct releases of medication, prolonging the mean residence time compared with lansoprazole (5.56-6.43 vs 2.83-3.23 hours, respectively). In 2 identical Phase III trials of the healing of EE, there were no significant differences in rates of complete healing after 8 weeks between dexlansoprazole 60 and 90 mg once daily and lansoprazole 30 mg once daily. In 2 studies of the maintenance of healing of EE, rates of healing at 6 months were significantly higher with dexlansoprazole 30, 60, and 90 mg once daily compared with placebo (P < 0.001). Patients with nonerosive reflux disease who received dexlansoprazole 30 or 60 mg once daily had significantly more 24-hour heartburn-free days compared with those who received placebo (P < 0.001). Dexlansoprazole was well tolerated compared with placebo or lansoprazole in all studies. CONCLUSIONS In the studies reviewed, dexlansoprazole was well tolerated and effective in the healing and maintenance of EE, and in the treatment of nonerosive reflux disease. However, most of the available evidence involved comparisons with placebo, making it difficult to draw meaningful conclusions about the place of dexlansoprazole among PPIs. More head-to-head comparative trials with other PPIs are needed to determine whether the unique formulation of dexlansoprazole translates into a clinically meaningful improvement in outcomes.

Abstract
OBJECTIVE: To describe the pharmacology, pharmacokinetics, and efficacy of dexlansoprazole in the treatment of heartburn associated with nonerosive gastroesophageal reflux disease (GERD) and healing and maintenance of healing of all grades of erosive esophagitis (EE). DATA SOURCES: Literature searches were conducted using MEDLINE Ovid (1950-December 2009, week 4) and EMBASE (1980-2009, week 53) using the term dexlansoprazole. References from articles obtained from the search were evaluated for other relevant citations. STUDY SELECTION AND DATA EXTRACTION: All articles published in English evaluating the pharmacology, pharmacokinetics, efficacy, and adverse effect profile of dexlansoprazole were selected for inclusion. DATA SYNTHESIS: Dexlansoprazole is the newest addition to the proton pump inhibitor (PPI) class and is approved for the treatment of heartburn associated with nonerosive GERD, healing of all grades of EE, as well as maintenance of healing of EE. Dexlansoprazole has a unique dual delayed-release formulation, which releases drug at 2 points in time; the first peak occurs 1-2 hours after administration and the second occurs within 4-5 hours after administration. In Phase 3 trials conducted in adults, researchers found that dexlansoprazole increases rates of healing of EE, as well as the maintenance of healing, compared to lansoprazole. Relief of heartburn symptoms was comparable among the dexlansoprazole and lansoprazole treatment groups. Common adverse effects of dexlansoprazole are similar to those of the other PPIs, including diarrhea, abdominal pain, nausea, upper respiratory infection, vomiting, and flatulence. CONCLUSIONS: Dexlansoprazole provides another treatment option for the management of EE and symptoms of heartburn. Considering that the cost of dexlansoprazole is not favorable, further studies evaluating potential advantages over other agents are necessary to define the role of dexlansoprazole in the treatment of these conditions.

Abstract
Although proton pump inhibitors (PPI) have a record of remarkable effectiveness and safety in the management of gastroesophageal reflux disease (GERD), several treatment challenges with PPI have emerged. Dexlansoprazole MR is the (R)-enantiomer of lansoprazole contained in a formulation that produces two distinct releases of drug and significantly extends the duration of active plasma concentrations and % time pH > 4 beyond that of conventional single-release PPI. Dexlansoprazole MR can be administered without regard to meals or the timing of meals in most patients. Dexlansoprazole MR 60 mg demonstrated similar efficacy for healing of erosive esophagitis at 8 weeks compared with lansoprazole 30 mg, and dexlansoprazole MR 30 mg was superior to placebo for maintenance of healed erosive esophagitis at 6 months with 99% of nights and 96% of days heartburn-free over 6 months in patients taking dexlansoprazole MR 30 mg. Superior relief of heartburn occurred in patients taking dexlansoprazole MR 30 mg (55% heartburn-free 24-hour periods) vs placebo (14%) for symptomatic nonerosive GERD. The safety profile of dexlansoprazole MR is similar to that of lansoprazole. The extended pharmacodynamic effects, added convenience, and efficacy and safety of dexlansoprazole MR offer a novel approach to gastric pH control in patients with acid-related disorders.
