BACKGROUND: The optimal treatment regimen or the duration of treatment for an endoscopic submucosal dissection (ESD)-induced gastric ulcer has not been established. The aim of this study was to assess the efficacy of novel proton-pump inhibitor, ilaprazole, for the treatment of ESD-induced gastric ulcer. METHODS: This was a prospective, open-label, randomized multicenter study. Between June 2015 and March 2018, a total of 176 patients (178 lesions) who underwent ESD for a gastric neoplasm were randomly allocated to receive the oral proton-pump inhibitor ilaprazole 20 mg or rabeprazole 20 mg daily for 8 weeks. The primary outcome was the ulcer healing rate at 4 and 8 weeks. RESULTS: A total of 155 (157 lesions) and 154 patients (156 lesions) were included in the modified intention-to-treat (mITT) and per-protocol analyses, respectively. There was no significant difference in the ulcer healing rate (ilaprazole vs. rabeprazole, 97.4% vs. 97.0 p = 0.78 at 4 weeks, 100% vs. 100%, p = 0.95 at 8 weeks in the mITT analysis) or stage of ulcer (scar stage, 25.6% vs. 17.7%, p = 0.25 at 4 weeks, 92.3% vs. 88.6%, p = 0.59 at 8 weeks in the mITT analysis) between the treatment groups. The quality of ulcer healing was not significantly different between the two groups. No independent predictive factor for higher-quality ulcer healing was found in the multivariate analysis. CONCLUSIONS: According to this trial, ilaprazole and rabeprazole showed no significant difference in the healing of artificial gastric ulcers. Most of the ulcers achieved complete healing within 4-8 weeks. TRIAL REGISTRATION: ClinicalTrial.gov NCT02638584.

Associations of proton pump inhibitors and hospitalization due to hyponatremia: A population-based case-control study was written by Falhammar, Henrik;Lindh, Jonatan D.;Calissendorff, Jan;Skov, Jakob;Nathanson, David;Mannheimer, Buster. And the article was included in European Journal of Internal Medicine in 2019.Recommanded Product: Sodium 2-(((4-(3-methoxypropoxy)-3-methylpyridin-2-yl)methyl)sulfinyl)benzo[d]imidazol-1-ide The following contents are mentioned in the article:

Background: Small observational studies and case reports have indicated that proton pump inhibitors (PPIs) may cause hyponatremia. Whether there is a difference between the individual PPIs is yet unknown. Since PPIs are one of the most commonly prescribed groups of drugs, even a rare adverse reaction may have large implications. The objective was to study the association between PPIs and hospitalization due to hyponatremia. Methods: This register-based case-control study was based on the general Swedish population. Patients hospitalized with a principal diagnosis of hyponatremia (n = 14,359) were compared to matched controls (n = 57,383). The association between newly initiated (≤90 days) and ongoing PPI use was explored using multivariable logistic regression adjusting for concomitant drugs, medical conditions, previous hospitalizations and socioeconomic factors. Results: Adjusted ORs (95%CI) for hospitalization due to hyponatremia, compared to controls, were for newly initiated: omeprazole 2.67 (2.37-3.01); pantoprazole 2.06 (1.32-3.19); lansoprazole 1.19 (0.72-1.94); esomeprazole 2.89 (2.21-3.79) and any PPI 2.78 (2.48-3.11). Only one individual had been newly initiated on rabeprazole and had been hospitalized due to hyponatremia. Adjusted ORs (95%CI) for individuals with ongoing treatment were for: omeprazole 1.04 (0.97-1.11); pantoprazole 0.81 (0.62-1.05); lansoprazole 0.90 (0.70-1.15); rabeprazole 3.34 (0.84-11.43); esomeprazole 1.12 (0.94-1.33) and any PPI 1.04 (0.98-1.11). Conclusions: With the exception of lansoprazole, this study suggests an association between any newly initiated PPI-treatment and hospitalization due to hyponatremia. Ongoing PPI use was not associated with an increased risk. This study involved multiple reactions and reactants, such as Sodium 2-(((4-(3-methoxypropoxy)-3-methylpyridin-2-yl)methyl)sulfinyl)benzo[d]imidazol-1-ide (cas: 117976-90-6Recommanded Product: Sodium 2-(((4-(3-methoxypropoxy)-3-methylpyridin-2-yl)methyl)sulfinyl)benzo[d]imidazol-1-ide).

Backgrounds/Aims: Functional dyspepsia is a disease involving a range of upper gastrointestinal symptoms derived from various pathophysiologies. Tablets containing a combination of rabeprazole and controlled-release (CR) mosapride were recently developed. To investigate a more effective treatment, this trial evaluated the efficacy and safety of UIC201609/UIC201610 as a preliminary study. Methods: A multicenter, double-blind, randomized study was performed on 30 subjects. UIC201609/UIC201610 (combination of rabeprazole and CR mosapride) was the case group, and the two control groups were rabeprazole 10 mg once a day and mosapride 15 mg CR tablet once a day. As a primary efficacy endpoint of the study, the changes in the total score of eight items of the Nepean Dyspepsia Index-Korean version were analyzed at 2 weeks and 4 weeks. The outcomes regarding safety were collected. Results: The total symptom score of Nepean Dyspepsia Index-Korean decreased in the rabeprazole single group (29.4±17.1), mosapride CR single group (33.4±15.6), and UIC201609/UIC201610 group (33.4±11.8) at 4 weeks without significant differences. On the other hand, the UIC201609/UIC201610 combination group showed more score reduction of pain in the upper abdomen, burning in the upper abdomen compared to each control group, but it did not reach statistical significance. No difference was found in safety analysis. Conclusions: UIC201609/UIC201610 once daily showed some improvement in epigastric pain and dyspepsia in patients with functional dyspepsia, but there was no significance. Further study based on the advanced clinical trial design will be needed to confirm the efficacy of UIC201609/UIC201610 combination therapy in the future.

To compare outcomes between patients with relapsed follicular lymphoma who received a nonmyeloablative allogeneic stem cell transplant (alloSCT) and those who received an autologous transplant (autoSCT). We evaluated 194 patients with follicular lymphoma who received an alloSCT (n = 98) or autoSCT (n = 96) at MD Anderson Cancer Center (Houston, TX). The transplant type used was based on donor availability and by Medicare reimbursement guidelines. Patients who received an alloSCT were enrolled in four consecutive trials in which they received Hudarabine1 cyclophosphamide (or bendamustine), and rituximab conditioning. autoSCT patients received R-BEAM (rituximab, carmustine, etoposide, cytarabine, and mclphalan). The median follow-up of survivors was 108 mo for the alloSCT group and 102 mo for the autoSCT group. Overall survival was significantly better for patients who received an alloSCT compared with those who received an autoSCT (62% vs. 46%; P = 0.048). Similarly, progression-free survival rates were 52% in patients who received an alloSCT and 31% in those who received an autoSCT (P < 0.001), and the 8-yr relapse rates were 11% and 43%, resp. (P < 0.0001). Only three patients in the alloSCT group relapsed beyond 3.5 years. In the alloSCT group, the rates for grade 2 to 4 acute graft-versushost disease (GVHD)1 grade 3 to 4 acute GVHD1 and extensive chronic GVHD were 22%, 9%, and 38%, resp. In the autoSCT group, the 8-yr incidence of secondary myelodysplasia was 11%. Nonrelapse mortality was similar between the two groups (15% vs. 11% at 8 years; P = 0.27). This study shows that alloSCT is curative and confers superior survival compared with autoSCT in patients with follicular lymphoma.

There is little published research to examine the best approach to the management of Helicobacter pylori in Myanmar. This study aimed to determine the relative efficacy and tolerability of sequential eradication therapy compared to Myanmar’s current recommendation of a concomitant four drug regimen. Patients were screened for H. pylori using monoclonal Stool Antigen Testing (SAT). Those testing pos. were randomized 1:1 to receive receive Myanmar’s first-line regimen of 14 days of concomitant rabeprazole, clarithromycin, amoxycillin and tinidazole (140 pills, cost US₂3) or 10 days of sequential rabeprazole, clarithromycin, amoxycillin and tinidazole (60 pills, cost US₁0). Adherence and adverse effects were recorded, and the efficacy of the regimens assessed with repeat SAT. Of the 1011 patients screened for H. pylori infection, 313 (31%) tested pos. There was no statistical difference in the cure rates of the two regimens in either intention-to-treat: 128/157 (82%; 95% confidence interval (CI): 75-87%) receiving sequential therapy vs. 123/156 (79%; 95% CI: 72-85%) receiving concomitant therapy (P = 0.55) or per-protocol anal.: 125/131 (95%; 95% CI: 90-98) receiving sequential therapy vs. 121/130 (93%; 95% CI: 87-96) receiving concomitant therapy (P = 0.42). Side effects of therapy were reported in 54/157 (47%) patients taking sequential therapy compared with 62/156 (53%) taking concomitant therapy, but this difference did not reach statistical significance (P = 0.33).

Rabeprazole sodium is a widely used drug for gastrointestinal disorders. Several anal. methods for identifying rabeprazole sodium and its impurities have been reported. However, the genotoxicity of rabeprazole sodium and its impurities is still unclear. Thus, it is necessary to develop anal. methods that can identify the structures of its impurities and evaluate their genotoxicity. Here, we used high-performance liquid chromatog.-quadrupole time-of-flight mass spectrometry for identifying the impurities in rabeprazole sodium enteric-coated tablets. Impurities in the samples were matched with synthesized impurities based on the exact mass and secondary mass spectrometry characteristics and then subjected to in silico anal. using the Derek and Sarah software, as well as in vitro genotoxicity evaluations. Our method successfully identified the impurities as 2-[[4-(3-methoxy propane)-3-methyl-N-oxido-2-pyridyl] Me sulfonyl]-1H-benzimidazole (impurity I), 2-[[4-(3-methoxy propane)-3-methyl-2-pyridyl]methyl sulfonyl]-benzimidazole (impurity II), 2-[[4-(3-methoxy propane)-3-methyl-2-pyridyl] methionyl]-1H-benzimidazole (impurity III), and 2-mercapto benzimidazole (impurity IV). In silico anal. predicted that impurity III demonstrated a structural alert; thus, this impurity was evaluated for in vitro genotoxicity using the Ames test and chromosomal aberration assay. Impurity III at concentrations of 7.5-30 Μg/mL had an aberration rate of over 5% with or without S-9 mix. Furthermore, impurity III at concentrations of 40-1000 Μg/plate significantly increased the number of mutagenic colonies with or without S-9 mix. These results indicated that impurity III should be regulated to the limit of 0.01%.

Only 363 formulations were prescribed by their generic names and 29.1% drugs were prescribed as fixed dose combinations. Polypharmacy was seen in 91.5% and 39%, resp., in hospital stay and during discharge. About 60.5% drugs were prescribed from the National list of essential medicine. Total 57 drugs were found to be potentially inappropriate. About 22% patients received at least one drug which was potentially inappropriate according to Beers criteria and around 14% drugs were prescribed inappropriately. This study suggests that use of potentially inappropriate medications is common in elderly patients, some of them associated with high degree of risk in terms of worsening of the co-morbidity or drug-drug interactions. There is a need for nationwide assessment and strategies that may reduce or overcome such high prevalence. This study involved multiple reactions and reactants, such as Sodium 2-(((4-(3-methoxypropoxy)-3-methylpyridin-2-yl)methyl)sulfinyl)benzo[d]imidazol-1-ide (cas: 117976-90-6Reference of 117976-90-6).

Sodium 2-(((4-(3-methoxypropoxy)-3-methylpyridin-2-yl)methyl)sulfinyl)benzo[d]imidazol-1-ide (cas: 117976-90-6) belongs to imidazole derivatives. Imidazole is the basic core of some natural products such as histidine, purine, histamine and DNA based structures, etc. Among the different heterocyclic compounds, imidazole is better known due to its broad range of chemical and biological properties. Imidazole based anticancer drug find applications in cancer chemotherapy. It is used as buffer component for purification of the histidine tagged recombinant proteins in immobilized metal-affinity chromatography (IMAC).Reference of 117976-90-6
