Comparing the Safety and Efficacy of Proton Pump Inhibitors and Histamine-2 Receptor Antagonists in the Management of Patients With Peptic Ulcer Disease: A Systematic Review. Cureus 2023; 15:e44341. [PMID: 37779765 PMCID: PMC10538946 DOI: 10.7759/cureus.44341] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2023] [Accepted: 08/29/2023] [Indexed: 10/03/2023] Open
Abstract
Peptic ulcer disease (PUD) refers to the occurrence of an open erosion in the inner lining of the stomach, duodenum, or sometimes lower esophagus. Treatments like proton pump inhibitors (PPIs) or histamine 2 receptor antagonists (H2RAs) are available on the market to efficiently treat the break in the mucosal lining. However, there is little evidence about the effects of the medication on the type and location of the ulcer and the epigastric pain caused by disintegration and increased acidity in the stomach. Given the above, we conducted a systematic review comparing the safety and efficacy of PPIs and H2RAs in various ulcer locations (gastric, duodenal, and pre-pyloric) and the effect of prolonging the treatment with the same medication or changing into a drug from another class in treatment-resistant ulcers. We employed major research literature databases and search engines such as PubMed, Medical Literature Analysis and Retrieval System Online (MEDLINE), Science Direct, and Google Scholar to find relevant articles. After a thorough screening, a quality check using various tools, and applying filters that suited our eligibility criteria, we identified eight articles, of which five were random clinical trials (RCTs), two review articles, and one meta-analysis. This study compares the different side effects of PPIs and H2RAs. Most studies concluded that omeprazole is superior in healing ulcers and bringing pain relief and that patients resistant to H2RAs can be treated better when switched to a PPI. This study also discusses the adverse effects of chronic use, such as diarrhea, constipation, headaches, and gastrointestinal infections. Patients on long-term PPI therapy are required to take calcium supplements to prevent the risk of fractures in older adults. Regarding long-term outcomes, PPIs remain the mainstay of treatment for peptic ulcer disease, based on the papers we reviewed.

Effects of postoperative use of proton pump inhibitors on gastrointestinal bleeding after endoscopic variceal treatment during hospitalization. World J Gastrointest Surg 2023; 15:82-93. [PMID: 36741070 PMCID: PMC9896494 DOI: 10.4240/wjgs.v15.i1.82] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/25/2022] [Revised: 10/11/2022] [Accepted: 11/07/2022] [Indexed: 01/17/2023] Open
Abstract
BACKGROUND Endoscopic variceal treatment (EVT) is recommended as the mainstay choice for the management of high-risk gastroesophageal varices and acute variceal bleeding in liver cirrhosis. Proton pump inhibitors (PPIs) are widely used for various gastric acid-related diseases. However, the effects of PPIs on the development of post-EVT complications, especially gastrointestinal bleeding (GIB), remain controversial.
AIM To evaluate the effects of postoperative use of PPIs on post-EVT complications in patients with liver cirrhosis during hospitalization.
METHODS Patients with a diagnosis of liver cirrhosis who were admitted to the Department of Gastroenterology of the General Hospital of Northern Theater Command, treated by an attending physician between January 2016 and June 2020 and underwent EVT during their hospitalization were included. Logistic regression analyses were performed to explore the effects of postoperative use of PPIs on the development of post-EVT complications during hospitalization. Odds ratios (ORs) with 95% confidence intervals (CIs) were calculated.
RESULTS A total of 143 patients were included. The incidence of post-EVT GIB and other post-EVT complications was 4.90% and 46.85%, respectively. In the overall analyses, postoperative use of PPIs did not significantly reduce the risk of post-EVT GIB (OR = 0.525, 95%CI = 0.113-2.438, P = 0.411) or other post-EVT complications (OR = 0.804, 95%CI = 0.413-1.565, P = 0.522). In the subgroup analyses according to the enrollment period, type and route of PPIs after the index EVT, use of PPIs before the index EVT, use of vasoactive drugs after the index EVT, indication of EVT (prophylactic and therapeutic), and presence of portal venous system thrombosis, ascites, and hepatocellular carcinoma, the effects of postoperative use of PPIs on the risk of post-EVT GIB or other post-EVT complications remain not statistically significant.
CONCLUSION Routine use of PPIs after EVT should not be recommended in patients with liver cirrhosis for the prevention of post-EVT complications during hospitalization.

The effect of rebamipide on non-steroidal anti-inflammatory drug-induced gastro-enteropathy: a multi-center, randomized pilot study. Korean J Intern Med 2022; 37:1153-1166. [PMID: 36375487 PMCID: PMC9666262 DOI: 10.3904/kjim.2021.216] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/06/2021] [Accepted: 02/19/2022] [Indexed: 11/06/2022] Open
Abstract
BACKGROUND/AIMS Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly-used medications, and ailments such as arthritis or heart disease, require long-term use of these drugs, which can induce gastroenteropathy with bleeding and ulcers. This study investigated the associations between efficacy, safety, and gastrointestinal symptoms linked to rebamipide and proton pump inhibitor administration in patients requiring long-term NSAID use. METHODS This study was a multi-center, randomized, open-labeled, pilot design. RESULTS Thirty-three patients were included. Of these, 15 were included in the study group and 18 were in the control group. NSAID-induced gastric ulcers, which were the primary outcome of this study, did not occur in either the study or control group. Changes in the number of small bowel erosions and ulcers were -0.6 ± 3.06 in the study group and 1.33 ± 4.71 in the control group. The number of subjects with mucosal breaks (defined as multiple erosions and/or ulcers) was three (20%) in the study group and six (40%) in the control group (p = 0.427). No serious adverse events occurred in either group. However, dyspepsia and skin rashes occurred in six patients (31.58%) in the study group and 13 (65%) in the control group (p = 0.036). CONCLUSION Although statistically significant differences were not generated, possibly as a result of the small sample size, mucosal breaks observed via capsule endoscopy revealed that rebamipide was likely to be more effective than lansoprazole in preventing small intestine damage caused by NSAIDs. Furthermore, fewer side-effects emerged with rebamipide.

Integration of a Physiologically Based Pharmacokinetic and Pharmacodynamic Model for Tegoprazan and Its Metabolite: Application for Predicting Food Effect and Intragastric pH Alterations. Pharmaceutics 2022; 14:pharmaceutics14061298.

Abstract
A physiologically based pharmacokinetic/pharmacodynamic (PBPK/PD) model for tegoprazan and its major metabolite M1 was developed to predict PK and PD profiles under various scenarios. The PBPK model for tegoprazan and M1 was developed and predicted using the SimCYP® simulator and verified using clinical study data obtained after a single administration of tegoprazan. The established PBPK/PD model was used to predict PK profiles after repeated administrations of tegoprazan, postprandial PK profiles, and intragastric pH changes. The predicted tegoprazan and M1 concentration-time profiles fit the observed profiles well. The arithmetic mean ratios (95% confidence intervals) of the predicted to observed values for the area under the curve (AUC0-24 h), maximum plasma drug concentration (Cmax), and clearance (CL) for tegoprazan and M1 were within a 30% interval. Delayed time of maximum concentration (Tmax) and decreased Cmax were predicted in the postprandial PK profiles compared with the fasted state. This PBPK/PD model may be used to predict PK profiles after repeated tegoprazan administrations and to predict differences in physiological factors in the gastrointestinal tract or changes in gastric acid pH after tegoprazan administration.

Abstract
OBJECTIVE To evaluate the association between proton pump inhibitor (PPI) use and in-hospital gastrointestinal (GI) bleeding in patients with acute coronary syndrome (ACS) taking dual antiplatelet therapy (DAPT). PATIENTS AND METHODS This study is based on the Improving Care for Cardiovascular Disease in China-ACS project, an ongoing collaborative registry and quality improvement project of the American Heart Association and the Chinese Society of Cardiology. A total of 25,567 patients with ACS taking DAPT from 172 hospitals from July 1, 2017, through December 31, 2018, were included. Multivariable Cox regression and propensity score-matched analyses were used to evaluate the association between PPI use and in-hospital GI bleeding. RESULTS Of these patients with ACS, 63.9% (n=16,332) were prescribed PPIs within 24 hours of admission. Patients using PPIs had a higher rate of GI bleeding compared with those not using PPIs (1.0% vs 0.5%; P<.001). In the multivariable Cox regression analysis, early PPI use was associated with a 58% higher risk of GI bleeding (hazard ratio, 1.58; 95% CI, 1.15 to 2.18; P=.005). Further propensity score matching attenuated the association but still showed that patients using PPIs had a higher rate of GI bleeding (0.8% vs 0.6%; P=.04). CONCLUSION In China, PPIs are widely used within 24 hours of admission in patients with ACS taking DAPT. An increased risk of GI bleeding is observed in inpatients with early PPI use. Randomized trials on early use of PPIs in patients with ACS receiving DAPT are warranted. TRIAL REGISTRATION clinicaltrials.gov Identifier: NCT02306616.

Abstract
BACKGROUND The current study aimed to design a novel combination of lansoprazole (LNS) and curcumin (CUR) solid oral dosage form using bioactive self-nanoemulsifying drug delivery systems (Bio-SSNEDDS). METHODS Liquid SNEDDS were prepared using the lipid-excipients: Imwitor988 (cosurfactant), Kolliphor El (surfactant), the bioactive black seed (BSO) and/or zanthoxylum rhetsa seed oils (ZRO). Liquid SNEDDS were loaded with CUR and LNS, then solidified using commercially available (uncured) and processed (cured) Neusilin® US2 (NUS2) adsorbent. A novel UHPLC method was validated to simultaneously quantify CUR and LNS in lipid-based formulations. The liquid SNEDDS were characterized in terms of self-emulsification, droplet size and zeta-potential measurements. The solidified SNEDDS were characterized by differential scanning calorimetry (DSC), X-ray powder diffraction (XRD), scanning electron microscopy (SEM), in vitro dissolution and stability in accelerated storage conditions. RESULTS Liquid SNEDDS containing BSO produced a transparent appearance and ultra-fine droplet size (14 nm) upon aqueous dilution. The solidified SNEDDS using cured and uncured NUS2 showed complete solidification with no particle agglomeration. DSC and XRD confirmed the conversion of crystalline CUR and LNS to the amorphous form in all solid SNEDDS samples. SEM images showed that CUR/LNS-SNEDDS were relatively spherical and regular in shape. The optimized solid SNEDDS showed higher percent of cumulative release as compared to the pure drugs. Curing NUS2 with 10% PVP led to significant enhancement of CUR and LNS dissolution efficiencies (up to 1.82- and 2.75-fold, respectively) compared to uncured NUS2-based solid SNEDDS. These findings could be attributed to the significant (50%) reduction in the micropore area% in cured NUS2 which reflects blocking very small pores allowing more space for the self-emulsification process to take place in the larger-size pores. Solid SNEDDS showed significant enhancement of liquid SNEDDS stability after 6 months storage in accelerated conditions. CONCLUSIONS The developed Bio-SSNEDDS of CUR and LNS using processed NUS2 could be used as a potential combination therapy to improve the treatment of peptic ulcers.

Abstract
Purpose
The purpose of this study is to evaluate the prescribing pattern of proton pump inhibitors (PPIs) in patients visiting the outpatient general medical clinic in a Tertiary Care Teaching Hospital.
Design/methodology/approach
A hospital-based cross-sectional study was conducted in 419 patients aged ≥18 years, visiting the outpatient general medicine clinic of a tertiary hospital and prescribed with at least one PPI, from July to September 2016 using a purposive sampling technique. Descriptive statistics were performed using IBM-SPSS 20.0 (IBM Corporation, Armonk, NY, USA).
Findings
Patients were mostly less than 30 years (30.78%) and female (58.95%). Pantoprazole was the most frequently prescribed PPIs (57.04%). The majority of PPIs were prescribed for acid peptic disorder (APD) (33.65%), followed by non-steroidal anti-inflammatory drugs (NSAIDs) prophylaxis (30.79%). Most of the PPIs were prescribed for twice-daily administration (68.26%). Nearly one-fourth (21.72%) of the patients presented with at least one additional medical condition, and almost all (99%) patients were receiving at least one additional drug along with PPIs.
Originality/value
The study suggests that PPIs are frequently prescribed and their use has been extended to other conditions that in fact do not require acid anti-secretory therapy. Result has highlighted the need for an interdisciplinary collaboration between pharmacists and medical professionals for the rational use of PPIs and promotion of PPIs prescription from the National List of Essential Medicines.

Front Pharmacol 2021; 12:667584. [PMID: 33995097 PMCID: PMC8118713 DOI: 10.3389/fphar.2021.667584] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2021] [Accepted: 03/17/2021] [Indexed: 11/26/2022] Open
Abstract
Background and aim: Bismuth quadruple therapy (BQT) or non-bismuth quadruple therapy (i.e., concomitant therapy) (CT) is the first-line regimens to eradicate H. pylori infection in areas with high prevalence of clarithromycin (CLA) resistance. Guidelines suggest that in areas of high prevalence of H. pylori strains with double resistance (i.e., CLA + metronidazole), BQT should be preferred to CT. The aim of this study was to evaluate the efficacy and safety of BQT administered through the three-in-one pill (Pylera) formulation in a large series of H. pylori–infected patients, naive to treatment in a region with high CLA and dual resistance. Patients and methods: We treated 250 patients (148 F and 102 M, mean age 48.6 years) with H. pylori infection naïve to treatment. Patients received esomeprazole 40 mg bid and Pylera 3 tablets qid for 10 days. Diagnosis of H. pylori infection was through 13C urea breath test (13C UBT), or stool antigen test or histology, as appropriate. The evaluation of eradication was through 13C UBT at least 45 days after the end of therapy. Incidence of treatment-related adverse events (TRAEs) was assessed through a questionnaire at the end of treatment. Compliance was considered good if at least 90% of medication had been taken. Statistical analysis was per intention-to-treat e per protocol (PP). 95% confidence intervals (CIs) were calculated. Results: 1) 13 patients (5.2%) discontinued therapy due to side effects; 2) eradication rates in ITT and PP were 227/250 (90.8%; 95% CI 86.3–93.7%) and 226/237 (95.3%; 95% CI 91–99%), respectively; 3) the prevalence of TRAEs was 26.8%; and 4) adherence to treatment was good with compliance greater than 90%. Conclusion: In this real-life study, we demonstrate that in an area with a high prevalence of H. pylori strains with CLA or CLA + metronidazole resistance, BQT using Pylera is an effective therapeutic strategy with ITT eradication rates higher than 90%; this therapy is associated with good compliance and low incidence of side effects.

Abstract
Rabeprazole belongs to the class of anti-secretory drugs, with benzimidazoles substitution. These drugs induce gastric acid secretion through precise inhibition of the enzyme H+/K+-ATPase (acid or proton pump). This effect helps to treat and prevent conditions in which gastric acid directly aggravates symptoms such as duodenal and gastric ulcers. This chapter includes a comprehensive review of rabeprazole in terms of nomenclature, its physical-chemical properties, methods of preparation and ADME profiles. In addition, the chapter also includes a review of several methods for analysis of rebeprazole in its dosage forms and biological fluids.

Increased risk of death associated with the use of proton-pump inhibitors in patients with dementia and controls - a pharmacoepidemiological claims data analysis. Eur J Neurol 2020; 27:1422-1428. [PMID: 32281706 PMCID: PMC7496707 DOI: 10.1111/ene.14252] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2020] [Accepted: 04/02/2020] [Indexed: 12/19/2022]
Abstract
Background and purpose The use of proton‐pump inhibitors (PPIs) was reported to be associated with increased mortality risk and has been proposed as a potential risk factor for neurodegenerative diseases. We aimed to assess the impact of PPI use on survival in patients with dementia as compared with controls. Methods This register‐based control‐matched cohort study included 28 428 patients with dementia ascertained by the prescription of antidementia drugs and two control individuals matched by sex, age and area of residence for each patient with dementia during the study period from 1 January 2005 to 30 June 2016. Cumulative defined daily doses (DDDs) of PPIs were extracted from the health insurance prescription registries. A multivariate Cox regression model for non‐proportional hazards was used to analyse mortality risk in dependence of PPI exposure, which was limited to 1 year preceding the date of cohort entry (index date) in order to avoid immortal time bias. Results The PPI exposure of 100 DDDs in the year before the index date was associated with an increased mortality risk in patients with dementia (adjusted hazard ratio, 1.07; 95% confidence intervals, 1.03–1.12), but also in controls (adjusted hazard ratio, 1.47; 95% confidence intervals, 1.31–1.64). The mortality risk in relation to PPI use was significantly lower in patients with dementia as compared with controls (P < 0.0001) and highest in the first 2 years after the index date in both cohorts. Conclusions Our findings promote more stringent pharmacovigilance strategies to avoid PPI use in cases lacking a clear indication for therapy or where potential risks outweigh the benefits.

Development and evaluation of an omeprazole-based delayed-release liquid oral dosage form. Int J Pharm 2019; 567:118416. [PMID: 31175991 DOI: 10.1016/j.ijpharm.2019.06.007] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2019] [Revised: 06/03/2019] [Accepted: 06/04/2019] [Indexed: 01/01/2023]
Abstract
Modified-release oral dosage forms are commonly used in pharmaceutics to delay or sustain the release of drugs. Nowadays, they are only marketed as solid dosage forms such as capsules or tablets. Therefore, the development of a liquid oral dosage form with modified-release properties has been keenly awaited to increase the compliance of patients with a swallowing impairment, such as paediatric, older or critically ill patients. In this study, a new technology has been developed that consists of multi-layered particles suspended extemporaneously in a syrup, using omeprazole as a model drug. The coating procedure was optimized to obtain a yield of minimum 90% w/w and a mean diameter below 500 µm. Eudragit® E100 and Eudragit® L100-55 were used to prevent the early release of omeprazole in the syrup and in the acidic environment of the stomach, respectively. These polymers allowed the stability of the coated particles to be ensured when dispersed in a liquid and the enteric release of the drug to be targeted. It was demonstrated that our new system presented similar release performances to existing marketed enteric dosage forms. It is able to protect omeprazole for 2 h in acidic medium at pH 1.2, while omeprazole was entirely released at pH 6.8 within 45 min. Once the final suspension is prepared extemporaneously, it presents sufficient stability to guarantee the administration of multiple doses filled into a syrup bottle and kept for a limited storage time at room temperature (e.g. up to 10 doses to be administered within 10 days).

Abstract
Aim While proton pump inhibitors (PPIs) are generally considered safe and well tolerated, frail older people who take PPIs long term may be susceptible to adverse events. This study characterized PPI use and determined factors associated with high-dose use among older adults in residential aged care services (RACSs). Methods A cross-sectional study of 383 residents of six South Australian RACSs within the same organization was conducted. Clinical, diagnostic, and medication data were collected by study nurses. The proportions of residents who took a PPI for > 8 weeks and without documented indications were calculated. Factors associated with high-dose PPI use compared to standard/low doses were identified using age- and sex-adjusted logistic regression models. Results 196 (51%) residents received a PPI, with 45 (23%) prescribed a high dose. Overall, 173 (88%) PPI users had documented clinical indications or received medications that can increase bleeding risk. Three-quarters of PPI users with gastroesophageal reflux disease or dyspepsia had received a PPI for > 8 weeks. High-dose PPI use was associated with increasing medication regimen complexity [odds ratio (OR) 1.02; 95% confidence interval (CI) 1.01–1.04 per one-point increase in Medication Regimen Complexity Index score] and a greater number of medications prescribed for regular use (OR 1.11; 95% CI 1.01–1.21 per additional medication). Conclusions Half of all residents received a PPI, of whom the majority had documented clinical indications or received medications that may increase bleeding risk. There remains an opportunity to review the continuing need for treatment and consider “step-down” approaches for high-dose PPI users.

Abstract
BACKGROUND Proton pump inhibitors (PPIs) are commonly used in the treatment of acid-related diseases; however, the association between the use of PPIs and potential risk of hypomagnesemia is controversial. METHODS In the present study, databases including PubMed, EMBASE, MEDLINE, PsycINFO, CINAHL, the Cochrane Library, and 4 Chinese databases were searched since the inception until April 2018. Previous observational studies on the incidence of hypomagnesemia in individuals exposed to PPIs were included. RESULTS This systematic review involved 15 studies including 129,347 participants, and the sample size varied from 52 to 95,205. Meta-analysis of 14 studies indicated that the use of PPIs increased the risk of hypomagnesemia [RR, 1.44, 95% CI, 1.13-1.76; I, 85.2%]. Subgroup analysis revealed that the use of PPI was not associated with the incidence of hypomagnesemia in outpatients [RR, 1.49; 95% CI, 0.83-2.14; I, 41.4%] and hospitalized patients [RR, 1.05; 95% CI, 0.81-1.29; I, 62.1%], respectively. The use of PPIs was not related to the risk of hypomagnesemia based on the cut-off values of 1.8 mg/dL [RR, 1.73; 95% CI, 0.87-2.58; I, 65.2%], 1.7 mg/dL [RR, 1.48; 95% CI, 0.90-2.06; I, 87.6%], and 1.6 mg/dL [RR, 0.98; 95% CI, 0.69-1.27; I, 67.9%]. CONCLUSION The association between the exposure to PPI and the incidence of hypomagnesemia remained unclear. Due to the remarkable heterogeneity in previous studies, a definitive conclusion could not be drawn. Further research should be conducted to investigate the relationship between the use of individual PPI and potential risk of hypomagnesemia, and a dose-response analysis may be required.

Abstract
BACKGROUND AND AIM Proton pump inhibitors (PPIs) are among the most commonly prescribed medications worldwide, with dramatic efficacy for upper gastrointestinal acid-related disorders. In recent years, however, the safety of long-term PPI use has been questioned. One issue based on scant and conflicting literature is the possibility of PPI-related hypomagnesemia. Our purpose was to assess for any clinically significant alteration in serum magnesium levels in large groups of patients taking different PPIs in varying doses, with or without diuretics. METHODS This was a retrospective review of patient records at time of hospitalization, from February 2012 to December 2014. Two thousand four hundred patients were randomly selected from a pool of 12 058 magnesium levels performed at or within 24 h of hospital admission. Patients were categorized in six groups based on outpatient PPI and/or diuretic use. The main outcome studied was hypomagnesemia, defined as serum magnesium level < 1.6 mg/dL. RESULTS Mean magnesium levels were normal in PPI users (1.84 ± 0.29 mg/dL [normal 1.6 to 2.5 mg/dL]) and PPI nonusers (1.85 ± 0.30 mg/dL), P = 0.40, and there was no statistical difference in the prevalence of hypomagnesemia (14.7% vs 15.1%, P = 0.77). In separate groups, there were also no significant differences in serum magnesium levels between those taking PPIs of varying doses, with or without concomitant diuretics, and those not taking PPIs or diuretics. CONCLUSION Regardless of PPI dosage or concomitant diuretics prescribed, magnesium levels were unaffected. Routine screening of serum magnesium in PPI patients appears unnecessary.

Abstract
Introduction Proton pump inhibitors therapy success in the treatment of gastroesophageal reflux disease (GERD) is a difficult task because the extent of mucosal damage has no relation with the severity of the symptoms. Aim To establish the efficacy of pantoprazole treatment in patients with erosive reflux disease (ERD) and in those with non-erosive reflux disease (NERD), by assessing symptom relief and quality of life. Treatment duration and adverse events associated with pantoprazole treatment were analysed. Material and methods This meta-analysis was based on three multicentre, prospective, open-label, phase IV trials conducted in Slovenia, Poland, and the Russian Federation. In total, 252 patients with GERD were included and treated with pantoprazole 40 mg once daily for 4 or 8 weeks, depending on the fulfilment of predefined healing criteria. Symptoms were assessed by patients on a scale from 0 to 3 and the quality of life on a rating scale from 1 to 10. Results Forty-five percent of patients fulfilled the healing criteria after 4 weeks of treatment, and 70% of patients after 8 weeks of treatment. Patients who failed to reach the healing criteria reported significant reduction of symptoms severity. The response to 8-week treatment was significantly higher in patients with ERD (76%) when compared to patients with NERD (64%). Discontinuation of treatment after 4 weeks was not associated with worsening of symptoms and did not affect quality of life. Pantoprazole treatment was associated with improvement of symptoms and the quality of life of GERD patients over 8 weeks of treatment and showed that GERD patients with persisting symptoms benefit from prolonging treatment to 8 weeks. Treatment with pantoprazole 40 mg was very well tolerated – more than 90% of patients were without adverse events throughout the whole study and only 4 patients discontinued the treatment due to adverse events related to pantoprazole treatment. Conclusions Pantoprazole 40 mg was associated with complete relief of GERD-related symptoms in the majority of patients with ERD and NERD. Furthermore, the severity of symptoms was significantly reduced in patients without complete relief of symptoms. Pantoprazole also continuously improved the quality of life of GERD patients over 8 weeks of treatment and was very well tolerated throughout the whole study. Therefore, this meta-analysis suggests that pantoprazole 40 mg once daily is an effective and well-tolerated choice for providing symptom relief of patients with GERD.

Abstract
T-cell-originated protein kinase (TOPK) is highly expressed in several cancer cells and promotes tumorigenesis and progression, and therefore, it is an important target for drug treatment of tumor. Pantoprazole (PPZ) was identified to be a TOPK inhibitor from FDA-approved drug database by structure based virtual ligand screening. Herein, the data indicated that pantoprazole inhibited TOPK activities by directly binding with TOPK in vitro and in vivo. Ex vivo studies showed that pantoprazole inhibited TOPK activities in JB6 Cl41 cells and HCT 116 colorectal cancer cells. Moreover, knockdown of TOPK in HCT 116 cells decreased their sensitivities to pantoprazole. Results of an in vivo study demonstrated that i.p. injection of pantoprazole in HCT 116 colon tumor-bearing mice effectively suppressed cancer growth. The TOPK downstream signaling molecule phospho-histone H3 in tumor tissues was also decreased after pantoprazole treatment. In short, pantoprazole can suppress growth of colorectal cancer cells as a TOPK inhibitor both in vitro and in vivo.

Abstract
The human mass balance of [14 C]Z-215, a novel proton pump inhibitor, was characterised in six healthy male volunteers following single oral administration of [14 C]Z-215 (20 mg, 3.7 MBq) to determine the elimination pathway of Z-215 and the distribution of its metabolites in plasma, urine, and faeces (NCT02618629). [14 C]Z-215 was rapidly absorbed, with a Cmax of 434 ng/mL at 0.38 h for Z-215 and 732 ng eq./mL at 0.5 h for total radioactivity. Means of 59.61% and 31.36% of the administered radioactive dose were excreted in urine and faeces, respectively, within 168 h post-dose. The majority of the dose was recovered within 24 h in urine and 96 h in faeces. Unchanged Z-215 was excreted in urine at trace levels but was not detected in faeces. The main components in plasma were Z-215 and Z-215 sulphone, accounting for 29.8% and 13.3% of the total circulating radioactivity, respectively. Additionally, Z-215 was metabolised through oxidation, reduction and conjugation. Our in vitro Z-215 metabolism study showed that the major isozyme contributing to the oxidation of Z-215, including the formation of Z-215 sulphone, was CYP3A4. In conclusion, Z-215 is well absorbed in humans and primarily eliminated via metabolism, where CYP3A4 plays an important role.

Abstract
Background Recent studies have suggested a potential increased risk of acute kidney injury (AKI) among proton-pump inhibitor (PPI) users. However, the present results are conflicting. Thus, we performed a meta-analysis to investigate the association between PPI therapy and the risk of AKI. Methods EMBASE, PubMed, Web of Science, and Cochrane Library databases (up to September 23, 2016) were systematically searched for any studies assessing the relationship between PPI use and risk of AKI. Studies that reported relevant risk ratios (RRs), odds ratios, or hazard ratios were included. We calculated the pooled RRs with 95% confidence intervals (CI) using a random-effects model of the meta-analysis. Subgroup analysis was conducted to explore the source of heterogeneity. Results Seven observational studies (five cohort studies and two case–control studies) were identified and included, and a total of 513,696 cases of PPI use among 2,404,236 participants were included in the meta-analysis. The pooled adjusted RR of AKI in patients with PPIs use was 1.61 (95% CI: 1.16–2.22; I2=98.1%). Furthermore, higher risks of AKI were found in the subgroups of cohort studies, participant’s average age <60 years, participants with and without baseline PPI excluded, sample size <300,000, and number of adjustments ≥11. Subgroup analyses revealed that participants with or without baseline PPI excluded might be a source of heterogeneity. Conclusion PPI use could be a risk factor for AKI and should be administered carefully. Nevertheless, some confounding factors might impact the outcomes. More well-designed prospective studies are needed to clarify the association.

Abstract
Proton-pump inhibitors (PPIs) are one of the most active ingredients prescribed in Spain. In recent decades there has been an overuse of these drugs in both outpatient clinics and hospitals that has lead to a significant increase in healthcare spending and to an increase in the risk of possible side effects. It is important for health professionals to know the accepted indications and the correct doses for the use of these drugs. On the market there are different types of PPI: omeprazole, pantoprazole, lansoprazole, rabeprazole and esomeprazole. Omeprazole is the oldest and most used PPI, being also the cheapest. Although there are no important differences between PPIs in curing diseases, esomeprazole, a new-generation PPI, has proved to be more effective in eradicating H. pylori and in healing severe esophagitis compared to other PPIs. In recent years the use of generic drugs has spread; these drugs have the same bioavailability than the original drugs. In the case of PPIs, the few comparative studies available in the literature between original and generic drugs have shown no significant differences in clinical efficacy.

Abstract
Because of the efficacy of proton pump inhibitors (PPIs), their the use is increasing dramatically. The risk of adverse effects of short-term PPI therapy is low, but there are important safety concerns for potential adverse effects of prolonged PPI therapy. Findings from studies assessing the association between PPI use and bone mineral density (BMD) and/or fracture risk are contradictory. The aim of this study was to prospectively assess potential association of PPI treatment with the 12-month change in BMD of the lumbar spine, femur neck, and total hip. The study was performed in 200 PPI users and 50 PPI nonusers. Lumbar spine (L1-L4), femur neck, and total hip BMD were measured by dual-energy X-ray absorptiometry at the baseline and at 12 months. A total of 209 subjects completed the entire 12 months of the study and were included in the final analysis. A Wilcoxon signed-rank test showed that at 12 months PPI use was associated with statistically significant reductions in femur neck and total hip T scores (Z = -2.764, p = 0.005 and Z = -3.281, p = 0.001, respectively). A multiple linear regression analysis showed that only esomeprazole added significantly to the prediction of total lumbar spine and femur neck T scores (p = 0.048 and p = 0.037, respectively). Compared with the baseline, 12 months of PPI treatment resulted in lower femur neck and total hip BMD T scores. Among the four PPIs studied, esomeprazole was independently associated with significant reduction of BMD, whereas omeprazole had no effects on BMD. Considering the widespread use of PPIs, BMD screening should be considered in the case of prolonged PPI use.

Abstract
Dexlansoprazole modified release (MR) is an R-enantiomer of lansoprazole and a new-generation proton pump inhibitor exhibiting high efficacy in the treatment of symptoms and lesions associated with erosive oesophagitis caused by gastroesophageal reflux disease (GERD). The dual release of the active ingredient - in the duodenum and the small intestine - makes it possible to achieve two peak concentrations at various times, within two and five hours of administration. Dexlansoprazole MR ensures the longest maintenance of drug concentration in the plasma of all known proton pump inhibitors, and the longest proton pump inhibitory effect. The basic indications for the drug include all forms of gastroesophageal reflux disease, especially with night-time heartburn and sleep disorders resulting from GERD. Dexlansoprazole can be taken regardless of meal times. It has a good safety profile and carries a low risk of adverse interactions with other drugs.

Abstract
Background Gastrointestinal disorders account for 7–10% of all consultations in primary care. General practitioners’ management of digestive disorders in Central and Eastern European countries is largely unknown. Aims To identify and compare variations in the self-perceived responsibilities of general practitioners in the management of digestive disorders in Central and Eastern Europe. Methods A cross-sectional survey of a randomized sample of primary care physicians from 9 countries was conducted. An anonymous questionnaire was sent via post to primary care doctors. Results We received 867 responses; the response rate was 28.9%. Over 70% of respondents reported familiarity with available guidelines for gastrointestinal diseases. For uninvestigated dyspepsia in patients under 45 years, the “test and treat” strategy was twice as popular as “test and scope”. The majority (59.8%) of family physicians would refer patients with rectal bleeding without alarm symptoms to a specialist (from 7.6% of doctors in Slovenia to 85.1% of doctors in Bulgaria; p<0.001). 93.4% of respondents declared their involvement in colorectal cancer screening. In the majority of countries, responding doctors most often reported that they order fecal occult blood tests. The exceptions were Estonia and Hungary, where the majority of family physicians referred patients to a specialist (p<0.001). Conclusions Physicians from Central and Eastern European countries understood the need for the use of guidelines for the care of patients with gastrointestinal problems, but there is broad variation between countries in their management. Numerous efforts should be undertaken to establish and implement international standards for digestive disorders’ management in general practice.

Abstract
Background It is unclear whether concomitant use of clopidogrel and proton-pump inhibitors (PPIs) increases the risk of recurrence of cardiovascular disease or death in patients at high risk of upper gastrointestinal (GI) bleeding. Methods Based on the Swedish Patient Register, a cohort of cardiovascular disease (including acute myocardial infarction, stroke and angina, from 2006 to 2008) was selected from a population with any diagnosis of upper GI bleeding. Data on drug prescription was retrieved from the Prescribed Drug Register. Patients entered into the cohort after their first discharge for cardiovascular disease and were followed up to death, recurrence of cardiovascular disease, or 90 days. A Cox regression model was conducted and hazard ratios (HRs) with 95% confidence intervals (CIs) were estimated to evaluate the risks among users of different drug prescriptions. Results Patients who were current users of only PPIs (HR 2.02, 95% CI 1.19-3.44), only clopidogrel (HR 1.14, 95% CI 0.53-2.45) and nonusers of both (HR 2.36, 95% CI 1.39-4.00) were at a higher risk of death compared with patients with a concomitant use. Results were similar among 1779 patients who had any history of upper GI bleeding (HR 2.05, 95% CI 1.18-3.54; HR 1.25, 95% CI 0.57-2.72; HR 2.30, 95% CI 1.33-3.98, respectively). Conclusion Among patients at high risk of upper GI bleeding, those with a concomitant use of PPIs and clopidogrel were at a decreased risk of mortality, and possibly also a decreased risk of recurrence of cardiovascular disease.

Abstract
Acid peptic disorders are the result of distinctive, but overlapping pathogenic mechanisms leading to either excessive acid secretion or diminished mucosal defense. They are common entities present in daily clinical practice that, owing to their chronicity, represent a significant cost to healthcare. Key elements in the success of controlling these entities have been the development of potent and safe drugs based on physiological targets. The histamine-2 receptor antagonists revolutionized the treatment of acid peptic disorders owing to their safety and efficacy profile. The proton-pump inhibitors (PPIs) represent a further therapeutic advance due to more potent inhibition of acid secretion. Ample data from clinical trials and observational experience have confirmed the utility of these agents in the treatment of acid peptic diseases, with differential efficacy and safety characteristics between and within drug classes. Paradigms in their speed and duration of action have underscored the need for new chemical entities that, from a single dose, would provide reliable duration of acid control, particularly at night. Moreover, PPIs reduce, but do not eliminate, the risk of ulcers in patients taking NSAIDs, reflecting untargeted physiopathologic pathways and a breach in the ability to sustain an intragastric pH of more than 4. This review provides an assessment of the current understanding of the physiology of acid production, a discussion of medications targeting gastric acid production and a review of efficacy in specific acid peptic diseases, as well as current challenges and future directions in the treatment of acid-mediated diseases.

Abstract
BACKGROUNDS AND AIMS Recent studies reported that pretreatment of proton pump inhibitors (PPIs) induced sensitization to chemotherapeutic agents in several cancer cells. The devastating effects of PPIs on tumor cells were discovered and raised great interests; therefore we designed the following experiments to fully explain the direct antitumor effects of PPIs. METHODS We compared the viability of gastric cancer cells and epithelia cells in buffered and unbuffered culture conditions with PPZ treatment by WST-8 assay. The sensitivity to cisplatin of gastric cancer cells with/without PPZ pretreatment was assessed by IC50 calculation and Annexin V/PI assay. The secretion of IL-6 was detected by ELISA. Western blot analysis and real time RT-PCR were used to evaluate the expression and activation of STAT3 and its downstream targets. RESULTS PPZ selectively exhibited a dose-dependent cytotoxic effect of gastric cancer cells in acidic unbuffered medium. Low dose of PPZ pretreatment (20 μg/mL) enhanced the sensitivity to cisplatin in gastric cancer cells. PPZ induced cell apoptosis and reduced the secretion of the pro-inflammatory cytokine IL-6 specifically in gastric cancer cells, but had no effect on the epithelia cells. Consequently, the activation of STAT3, not the total amount, was suppressed by PPZ in gastric cancer cells. The downstream targets of STAT3, c-Myc, cyclin D1 and Bcl-2 were also down-regulated. CONCLUSION PPZ causes gastric cancer cell death by induction of apoptosis and its mechanism of action is mediated in part via the inhibition of IL-6/STAT3 pathway.

Abstract
Background Proton pump inhibitors (PPI) are a widely-used class of drugs for the treatment of gastro-esophageal reflux disease and other acid-related disorders of the gastrointestinal tract. As a class, PPIs have demonstrated a favorable safety profile. However, case reports have suggested that this class of drugs may be linked to acute kidney injury, which may in turn lead to chronic injury or failure. The objective of this study was to determine if an association between PPIs and kidney failure exists and to estimate an effect size for the relationship between PPI use and renal disease. Methods A nested case–control study was conducted in a privately insured population in a single Midwestern state including a total of 184,480 patients aged 18 years or older who were continuously enrolled with the insurer for at least 24 months between September 2002 and November 2005. Of the patients eligible for the study, 854 cases were identified as having at least two claims for an acute renal disease diagnosis. Cases were randomly matched with up to four controls (n = 3,289) based on age, gender, county of residence, and date of entry into the cohort. Patient demographic data, PPI use, illnesses, and medications associated with renal disease and a proxy for health status using pre-existing patient comorbidities were collected from inpatient, professional, and prescription claims data. Conditional logistic regression models were used to evaluate the association between renal disease and PPI use. Results Renal disease was positively associated with PPI use (odds ratio [OR] 1.72, 95% confidence interval [CI] 1.27, 2.32, p < 0.001) even after controlling for potential confounding conditions. After removing patients with potential confounding disease states from the study population, the number of cases (195 of the 854) and controls (607) was lower, but the relationship between renal disease and PPI use remained consistent (OR 2.25, CI 1.09-4.62, p < 0.001). Conclusions Patients with a renal disease diagnosis were twice as likely to have used a previous prescription for a PPI. Therefore, it is necessary for physicians to increase recognition of patient complaints or clinical manifestations of this potentially harmful event in order to prevent further injury.

Abstract
BACKGROUND Aspirin therapy is associated with adverse upper gastrointestinal effects. PA32540 is a coordinated-delivery tablet containing enteric-coated aspirin (EC-ASA) 325 mg and immediate-release (IR) omeprazole 40 mg. Immediate-release omeprazole (located in outer layer of tablet) is available for instantaneous dissolution rapidly after ingestion, while dissolution of the EC-ASA core is delayed until pH >5.5. AIM To compare the pharmacodynamic and pharmacokinetic effects of PA32540 (EC-ASA 325 mg + IR-omeprazole 40 mg) vs. enteric-coated (EC)-omeprazole 40 mg. METHODS This single-centre, open-label, randomised, two-way crossover study in healthy volunteers compared 7 days of once-daily dosing with PA32540 with 7 days of once-daily EC-ASA 325 mg + EC-omeprazole 40 mg dosed concomitantly. The primary endpoint was per cent time intragastric pH >4 over 24 h on Day 7. A key secondary endpoint was determination of the pharmacokinetics of omeprazole and salicylic acid. RESULTS Twenty-six subjects (mean age 29 years) were enrolled into the study. On Day 7, mean per cent time intragastric pH >4 was 50.6% for PA32540 and 57.6% for EC-omeprazole 40 mg (P = 0.004) and geometric least squares mean AUC0-24 for omeprazole was 1446 h*ng/mL for PA32540 and 2558 h*ng/mL for EC-omeprazole 40 mg. Day 7 median Tmax of omeprazole was 0.5 h for PA32540 and 1.25 h for EC-omeprazole 40 mg. CONCLUSION Total exposure to omeprazole from PA32540 was 57% of that from EC-omeprazole for the same dose amount (40 mg), while absolute difference in 24-h acid control was 7%. Omeprazole exposure and pH control with PA32540 appear similar to EC-omeprazole 20 mg.

Abstract
INTRODUCTION Although the exact prevalence of proton pump inhibitor (PPI) use in cancer patients is not known, it is generally perceived to be widespread. PPIs are generally well tolerated and carry an excellent safety profile. However, increasing and longer term PPI use has raised concerns about the risk of pneumonia, bone fractures and enteric infections, and a possible interaction with clopidogrel that could increase the risk of cardiovascular events. AREAS COVERED We conducted a PubMed search of English language articles addressing the safety and adverse events associated with PPI use with particular emphasis in cancer patients. EXPERT OPINION PPIs, frequently used in cancer patients, are generally well tolerated and carry an excellent safety profile. PPI-induced acid suppression may increase the risk of Clostridium difficile or other enteric infections, nutritional deficiencies and community acquired pneumonia, all particularly important in cancer patients. The indications for PPI use in cancer patients should be carefully reviewed prior to use.

Abstract
Proton pump inhibitors (PPIs) are one of the most commonly prescribed classes of medications in the United States. By inhibiting gastric H/K adenosine triphosphatase via covalent binding to the cysteine residues of the proton pump, they provide the most potent acid suppression available. Long-term PPI use accounts for the majority of total PPI use. Absolute indications include peptic ulcer disease, chronic nonsteroidal anti-inflammatory drugs use, treatment of Helicobacter pylori, and erosive esophagitis. Although PPIs are generally considered safe, numerous adverse effects, particularly associated with long-term use have been reported. Many patients receiving chronic PPI therapy do not have clear indications for their use, prompting consideration for reduction or discontinuation of their use. This article reviews the indications for PPI use, the adverse effects/risks involved with their use, and conditions in which their use is controversial.

Abstract
BACKGROUND The changes, advances, and new discoveries regarding different aspects of gastroesophageal reflux disease (GERD) have made it necessary to update the Mexican Consensus published in 2002. AIMS To elaborate a new Mexican Consensus on GERD. METHODS The general project coordinators selected six GERD experts to carry out an extensive review of the literature for the purpose of elaborating statements on the principal aspects of GERD. These were then placed under the consideration of specialists in the study of this disease. Definitive approval by all participants was reached using the modified Delphi method with three rounds of anonymous and iterative voting. The following scale was employed: A- in complete agreement; B- in agreement, but with minor concerns; C- in agreement, but with major concerns; D- in disagreement, but with major concerns; E- in disagreement, but with minor concerns; or F- in complete disagreement. Consensus was declared when 67.00% or more of the participants concurred on a category of agreement (A, B, or C). RESULTS A consensus was reached on 160 of the statements upon completion of the voting rounds, with 90.00% concurrence for the majority of them. CONCLUSIONS The 2011 Mexican Consensus on Gastroesophageal Disease is a practical and up-to-date consultation tool, providing the opinion of Mexican experts on all the new information available about this disease. It allows there to be homogeneity in diagnostic and therapeutic criteria, all of which serves to benefit our patients.

Abstract
BACKGROUND The decreasing efficacy of H. pylori eradication treatments over time makes the search for better regimens and adjuvant medications a priority. AIM To conduct a meta-analysis of studies comparing rabeprazole or esomeprazole with other proton pump inhibitors (PPI) or with each other in H. pylori eradication treatment. SELECTION OF STUDIES Randomised clinical trials comparing esomeprazole or rabeprazole with first-generation PPIs (omeprazole-lansoprazole-pantoprazole) or with each other. RESULTS The meta-analysis (35 studies, 5998 patients) showed higher eradication rates for esomeprazole than for first-generation PPIs: 82.3% vs. 77.6%; OR = 1.32(1.01-1.73); NNT = 21. Rabeprazole also showed better results than first-generation PPIs: 80.5% vs. 76.2%; OR = 1.21(1.02-1.42); NNT = 23. PPI dosage sub-analysis: only esomeprazole 40 mg b.d. improved results [83.5% esomeprazole vs. 72.4% first generation; OR = 2.27(1.07-4.82); NNT = 9]. Whereas rabeprazole 10 and 20 mg b.d. maintained results, esomeprazole 20 mg b.d. obtained lower efficacy. Esomeprazole vs. rabeprazole sub-analysis (five studies): no significant differences were found: 78.7% vs. 76.7%; OR = 0.90(0.70-1.17). CYP2C19 sub-analysis: Genotype did not significantly affect eradication either in first [OR = 1.76(0.99-3.12)] or new generation [OR = 1.19(0.73-1.95)] PPIs. However, sub-analysis considering only extensive metaboliser patients showed higher eradication with new-generation PPIs [OR = 1.37(1.02-1.84)]. CONCLUSIONS Esomeprazole and rabeprazole show better overall H. pylori eradication rates than first-generation PPIs. This clinical benefit is more pronounced in esomeprazole 40 mg b.d. regimens. In CYP2C19 extensive metabolisers, new-generation PPIs are more effective than first-generation PPIs for H. pylori eradication. However, a general recommendation of using new-generation PPIs in all scenarios remains unclear.

Abstract
UNLABELLED Gastroesophageal reflux disease (GERD) constitutes a significant health problem in societies of high socioeconomic status. The notion of quality of life is broader than the definition of health and encompasses two aspects: the subjective and objective one. The tools used for the evaluation of quality of life are questionnaires. The aim of the study was the evaluation of the original quality of life questionnaire in patients with gastroesophageal reflux disease treated for 4 weeks with a single dose of omeprazole at 20 mg daily. MATERIAL AND METHODS The original quality of life questionnaire was formulated based on the Likert method. Four time levels of complaint persistence were introduced. The patients were asked 10 questions with earlier prepared answers marked by the respondents. Each of the questions corresponded to a certain time level of complaint persistence. The data obtained from the questionnaires were subject to statistical analysis. The studies were conducted on a group of 10,623 patients. Adequate methods were used in the statistical analysis of data from obtained answers. The significance threshold for each of the studies was p < 0.01, which means that the obtained conclusions are true with the probability of at least 99%. The majority of statistical calculations were performed with the use of STATISTICA 7.0 and Excel software. RESULTS Improvement of quality of life was found in all the studied aspects: physical (questions 1, 3, 4, 5, 7), functional (question 6), emotional (questions 2, 10) and social (questions 8, 9). No correlation with age or gender was found. The analysis of test correctness was conducted, revealing reliability, validity, sensitivity, appropriateness and practicality of the questionnaire. CONCLUSIONS 1. The original quality of life questionnaire meets the requirements for the tools evaluating quality of life in gastroesophageal reflux disease. 2. The usefulness of questionnaire was confirmed in a group of 10,623 patients with gastroesophageal reflux disease in the Polish population. 3. The questionnaire equals the international tests, while its advantages are the ease of completion and high level of perception.

Abstract
Ever since they were launched, proton pump inhibitors (PPIs) have been regarded as profligate prescription interventions and have become a favourite target for pharmacy advisers. Now that they are cheap, with generic omeprazole 20 mg daily costing £1.88 per month (£24.51 per annum) in the UK, it is time to ask whether this status should be reviewed, whether there are areas where the message should be reversed and whether there are any circumstances in which the extra cost of branded PPIs or combined preparations is justified. Equally, with the recognition of an extended toxicity profile, is prescribing profligacy not an economic but a safety issue?

Abstract
AIM To elucidate the effect and underlying mechanisms of omeprazole action on Mg(2+) transport across the intestinal epithelium. METHODS Caco-2 monolayers were cultured in various dose omeprazole-containing media for 14 or 21 d before being inserted into a modified Ussing chamber apparatus to investigate the bi-directional Mg(2+) transport and electrical parameters. Paracellular permeability of the monolayer was also observed by the dilution potential technique and a cation permeability study. An Arrhenius plot was performed to elucidate the activation energy of passive Mg(2+) transport across the Caco-2 monolayers. RESULTS Both apical to basolateral and basolateral to apical passive Mg(2+) fluxes of omeprazole-treated epithelium were decreased in a dose- and time-dependent manner. Omeprazole also decreased the paracellular cation selectivity and changed the paracellular selective permeability profile of Caco-2 epithelium to Li(+), Na(+), K(+), Rb(+), and Cs(+) from series VII to series VI of the Eisenman sequence. The Arrhenius plot revealed the higher activation energy for passive Mg(2+) transport in omeprazole-treated epithelium than that of control epithelium, indicating that omeprazole affected the paracellular channel of Caco-2 epithelium in such a way that Mg(2+) movement was impeded. CONCLUSION Omeprazole decreased paracellular cation permeability and increased the activation energy for passive Mg(2+) transport of Caco-2 monolayers that led to the suppression of passive Mg(2+) absorption.

Abstract
Proton pump inhibitors (PPIs) are known to possess anti-inflammatory properties. Inflammatory processes, including astrocytic activation, are implicated in the pathogenesis of different neurodegenerative diseases. Our recent study has indicated that interferon (IFN)-γ-induced astrocytic neurotoxicity is mediated, at least in part, by phosphorylation of signal transducer and activator of transcription (STAT) 3. We therefore studied the effects of PPIs on IFN-γ-induced neurotoxicity and STAT3 activation of human astrocytes. Both lansoprazole (LPZ) and omeprazole (OPZ) significantly attenuated IFN-γ-induced neurotoxicity of human astrocytes and astrocytoma cells. These drugs inhibited IFN-γ-induced phosphorylation of STAT 3, but not STAT1. We found that LPZ significantly reduced secretion of IFN-γ-inducible T cell α chemoattractant from IFN-γ-activated astrocytes. Neither LPZ nor OPZ suppressed expression of intercellular adhesion molecule-1 by IFN-γ-activated astrocytes. These results suggest that PPIs attenuate IFN-γ-induced neurotoxicity of human astrocytes through inhibition of the STAT3 signaling pathway. PPIs that possess antineurotoxic properties may be a useful treatment option for Alzheimer's disease and other neuroinflammatory disorders associated with activated astrocytes.

Abstract
Pantoprazole is a proton pump inhibitor (PPI) that binds irreversibly and specifically to the proton pump, thereby reducing gastric acid secretion. Pantoprazole has a relatively long duration of action compared with other PPIs, and a lower propensity to become activated in slightly acidic body compartments. To date, no drug-drug interactions have been identified with pantoprazole in numerous interaction studies. Overall, in the short-term (8-10 weeks) initial treatment of gastro-oesophageal reflux disease (a condition that occurs when the reflux of gastric contents causes troublesome symptoms and/or complications) and long-term (6-24 months) maintenance therapy, oral pantoprazole 20 or 40 mg/day demonstrated similar efficacy to omeprazole, lansoprazole and esomeprazole and greater efficacy than histamine type 2 receptor antagonists. Pantoprazole is also effective in treating and preventing NSAID-related gastric and gastroduodenal injury. The optimal adult oral dose for gastric acid-related disorders is pantoprazole 40 mg once daily. Although data are limited, pantoprazole 20 or 40 mg/day was effective and well tolerated in the treatment of acid-related disorders in children and adolescents. Pantoprazole was also well tolerated in adults with acid-related disorders in short- and long-term studies. Thus, pantoprazole is a valuable agent for the management of acid-related disorders.

Abstract
PURPOSE OF REVIEW To summarize this year's relevant literature on the causes and mechanisms of autoimmune gastritis. RECENT FINDINGS It is increasingly recognized that parietal cell antibodies, previously assumed exclusive to autoimmune gastritis, are associated with Helicobacter pylori infection. Successful H. pylori eradication with antibiotic treatment decreases antiparietal cell antibodies. Interestingly, vitamin B(12) deficiency, previously associated with autoimmune gastritis, is increasingly described in the elderly, irrespective of H. pylori status. Autoimmune gastritis that mostly affects patients of Scandinavian descent, was reported this year from China, and corpus predominant gastritis (autoimmune associated) was reported from Japan. It is difficult to evaluate the role played by genetics, increased use of proton pump inhibitors, and H. pylori infection, as current patient work-up does not regularly include screening for parietal cell and intrinsic-factor antibodies. As these clinicopathologic changes are seen in both H. pylori-positive patients, and in H. pylori-naïve patients, the debate continues for mechanisms involved in H. pylori-naïve patients. SUMMARY The clinical features commonly associated with autoimmune gastritis are increasingly seen in the elderly, irrespective of H. pylori status. Though some patients are genetically predisposed, long-term proton pump inhibitor use increases the prevalence of clinicopathologic features irrespective of genetic tendency.

Abstract
Rabeprazole (Aciphex, Alfence, Pariet) is a proton pump inhibitor (PPI) used for the treatment of adults with conditions requiring a reduction of gastric acid secretion such as erosive or ulcerative gastro-oesophageal reflux disease (GORD), non-erosive reflux disease (NERD), duodenal and gastric ulcers, and pathological hypersecretory conditions including Zollinger-Ellison syndrome (ZES). It is also used as part of combination therapy for the eradication of Helicobacter pylori, a pathogen frequently implicated in the development of gastric and duodenal ulcers. Rabeprazole has a well established efficacy and safety profile in the treatment of gastric acid-related diseases. Rabeprazole is a useful, well tolerated and cost-effective option for the treatment of GORD, NERD, peptic ulcer and other gastric acid-related diseases (including ZES), and provides an appropriate alternative to other currently available PPIs, with the added benefits of having a consistent efficacy profile and low drug interaction potential due to its predominantly nonenzymatic metabolism.
