This study aimed to identify the components of proton pump inhibitors (PPIs) or potassium-competitive acid blocker (PCAB) that lead to cardiovascular events in individuals of working age. We analyzed large claims data of individuals who were administered PPIs or PCAB. We enrolled working-age individuals administered PPI or PCAB without cardiovascular history with a 12-month screening and 12-month observation period and determined the proportion of cardiovascular events and the predictive factors of cardiovascular events in this population. Among the eligible individuals, 0.5% (456/91098) had cardiovascular events during the 12-month observation period. Predictive factors for cardiovascular events were age for +1 year (p < 0.0001), male sex (p < 0.0001), hypertension (p = 0.0056), and diabetes mellitus (p < 0.0001). The cardiovascular disease risk was higher in working-age individuals administered lansoprazole than in those administered other drugs (vs. rabeprazole; p = 0.0002, vs. omeprazole; p = 0.0046, vs. vonoprazan; p < 0.0001, and vs. esomeprazole; p < 0.0001). We identified the risk for cardiovascular events in individuals being treated with lansoprazole. Lansoprazole is known for its higher CYP2C19 inhibition activity compared with other PPIs or PCAB. A possible mechanism by which lansoprazole may lead to cardiovascular events is inhibiting the generation of epoxyeicosatrienoic acids from arachidonic acids, an intrinsic cardioprotective activator via CYP2C19 inhibition. Thus, we recommend avoiding administering lansoprazole to working-age individuals require PPIs or PCAB.

Abstract: Background: Helicobacter pylori (H. pylori) is a common pathogen in development of peptic ulcers with pyroptosis. Rabeprazole, a critical component of standard triple therapy, has been widely used as the first-line regimen for H. pylori infectious treatment. The aim of this study to explore the function of Rabeprazole on cell pyroptosis in vitro. Methods: The clin. sample from patients diagnosed with or without H. pylori-infection were collected to analyze by Immunohistochem. (IHC). Real-time quant. PCR (qPCR), western blot (WB) and enzyme linked immunosorbent assay (Elisa) were performed to analyze the effect of Rabeprazole on cell pyroptosis, including LDH, IL-1β and IL-18. Results: In this study, we showed that Rabeprazole regulated a phenomenon of cell pyroptosis as confirmed by lactate dehydrogenase (LDH) assay. Further results showed that Rabeprazole inhibited cell pyroptosis in gastric epithelial cells by alleviating GSDMD-executed pyroptosis, leading to decrease IL-1β and IL-18 mature and secretion, which is attributed to NLRP3 inflammasome activation inhibition. Further anal. showed that ASC, NLRP3 and Caspase-1, was significantly repressed in response to Rabeprazole stimulation, resulting in decreasing cleaved-caspase-1 expression. Most important, NLRP3 and GSDMD is significantly increased in gastric tissue of patients with H. pylori infection. Conclusion: These findings revealed a critical role of Rabeprazole in cell pyroptosis in patients with H. pylori infection, suggesting that targeting cell pyroptosis is an alternative strategy in improving H. pylori treatment.

Proton pump inhibitors (PPIs) alter the composition of the intestinal microbiome, exacerbating indomethacin (IND)-induced small intestinal damage. Vonoprazan fumarate inhibits gastric acid secretion using a different mechanism from PPIs. We investigated the effects of both drugs on the intestinal microbiome and IND-induced small intestinal damage. We sought to clarify whether PPI-induced dysbiosis and worsening of the damage were due to a specific drug class effect of PPIs. Rabeprazole administration increased operational taxonomic unit numbers in the small intestines of C57BL/6 J mice, whereas the difference was not significant in the vonoprazan-treated group but exhibited a trend. Permutational multivariate analysis of variance of the unweighted UniFrac distances showed significant differences between vehicle- and vonoprazan- or rabeprazole-treated groups. L. johnsonii was the predominant microbial species, and the population ratio decreased after vonoprazan and rabeprazole administration. The vonoprazan- and rabeprazole-treated groups showed increased IND-induced damage. This high sensitivity to IND-induced damage was evaluated by transplantation with contents from the small intestine of mice treated with either vonoprazan or rabeprazole. Supplementation of L. johnsonii orally in mice treated with rabeprazole and vonoprazan prevented the increase in IND-induced small intestinal damage. In conclusion, both rabeprazole and vonoprazan aggravated NSAID-induced small intestinal injury by reducing the population of L. johnsonii in the small intestine via suppressing gastric acid secretion.

Background: Rabeprazole at 10 or 20 mg twice daily (b.i.d.) has been reported to be highly effective in the treatment of proton pump inhibitor (PPI)-resistant reflux esophagitis (RE) that is refractory to the standard once-daily PPI regimen. We evaluated the efficacy and safety of rabeprazole maintenance therapy at 10 mg once daily (q.d.) or b.i.d. for longer than 8 wk. Methods: Patients with RE refractory to standard PPI regimens for at least 8 wk were enrolled. They were treated with rabeprazole at 10 or 20 mg b.i.d. for 8 wk during the open-label treatment period. After endoscopic examination, those with confirmed healing entered the subsequent double-blind maintenance therapy. During this period, the subjects were randomized to receive rabeprazole 10 mg q.d. (control) or 10 mg b.i.d. The primary endpoint was the endoscopic no-recurrence rate at Week 52. Results: In total, 517 subjects entered the treatment, and 359 subjects continued on maintenance therapy. The full anal. set for central assessment included 343 subjects. The no-recurrence rate at Week 52 was significantly higher in the b.i.d. group (73.9%; p < 0.001, χ² test) than in the q.d. group (44.8%). In particular, the b.i.d. regimen was more effective in all subgroups with Los Angeles Classification Grade B to D at treatment entry. Conclusions: In the maintenance treatment of PPI-resistant RE, rabeprazole at 10 mg b.i.d. exerted a stronger recurrence-preventing effect than 10 mg q.d. over 52 wk. No particular safety issues were noted during long-term administration. ClinicalTrials.gov number: NCT02135107.

Proton pump inhibitor (PPI)-refractory gastroesophageal reflux disease (GERD) leads to a clin. decline in the quality of life (QOL). Therefore, new treatment options are needed. We performed a multicenter, randomized, parallel-group exploratory trial to determine the efficacy of hangeshashinto (HST) in patients with PPI-refractory GERD. We enrolled 78 patients with PPI-refractory GERD for standard PPI regimens for at least 4 wk and randomly assigned patients to receive either a combination of usual dose of rabeprazole (10 mg/day) + HST (7.5 g/day; HST group) or a double dose of rabeprazole (20 mg/day; double-dose PPI group). The primary end points were the extent of improvement in FSSG (Frequency Scale for the Symptoms of GERD) score and the change over time in FSSG score. There was no significant difference in terms of the improvement degree of the FSSG score between the two groups. Although the total FSSG score and reflux syndrome score decreased significantly for both groups over time (p < 0.001), the acid-related dyspepsia (ARD) score decreased significantly in the HST group from 1 wk after drug administration (p < 0.05), indicating an improvement in the condition earlier than in the double-dose PPI group. Moreover, in examinations concerning BMI and age, the HST group had a significantly higher improvement degree of ARD score in patients with BMI < 22 (p < 0.05) and aged < 65 years (p < 0.05) than the double-dose PPI group. HST may be beneficial for patients with PPI-refractory GERD, particularly in non-obese and non-elderly patients with dyspepsia symptoms.

A unified platform enabling biomarker ranking and validation for 1562 drugs using transcriptomic data of 1250 cancer cell lines was written by Tibor Fekete, Janos;Gyorffy, Balazs. And the article was included in Computational and Structural Biotechnology Journal in 2022.Recommanded Product: 16506-27-7 The following contents are mentioned in the article:

In vitro cell line models provide a valuable resource to investigate compounds useful in the systemic chemotherapy of cancer. However, the due to the dispersal of the data into several different databases, the utilization of these resources is limited. Here, our aim was to establish a platform enabling the validation of chemoresistance-associated genes and the ranking of available cell line models. We processed four independent databases, DepMap, GDSC1, GDSC2, and CTRP. The gene expression data was quantile normalized and HUGO gene names were assigned to have unambiguous identification of the genes. Resistance values were exported for all agents. The correlation between gene expression and therapy resistance is computed using ROC test. We combined four datasets with chemosensitivity data of 1562 agents and transcriptome-level gene expression of 1250 cancer cell lines. We have set up an online tool utilizing this database to correlate available cell line sensitivity data and treatment response in a uniform anal. pipeline. We employed the established pipeline to by rank genes related to resistance against afatinib and lapatinib, two inhibitors of the tyrosine-kinase domain of ERBB2. The computational tool is useful 1) to correlate gene expression with resistance, 2) to identify and rank resistant and sensitive cell lines, and 3) to rank resistance associated genes, cancer hallmarks, and gene ontol. pathways. The platform will be an invaluable support to speed up cancer research by validating gene-resistance correlations and by selecting the best cell line models for new experiments This study involved multiple reactions and reactants, such as 4-(5-(Bis(2-chloroethyl)amino)-1-methyl-1H-benzo[d]imidazol-2-yl)butanoic acid (cas: 16506-27-7Recommanded Product: 16506-27-7).

Obinutuzumab, a novel glyco-engineered anti-CD20 monoclonal antibody, has been developed to have superior efficacy to rituximab. Although obinutuzumab frequently causes infusion reactions (IR) during initial administration, there have been few reports about the frequency and risk factors for IR. In this study, the author investigated the frequency of clin. relevant IR during obinutuzumab administration and explored the risk factors associated with obinutuzumab-induced IR. The author included patients who were administered obinutuzumab for CD20+ B-cell non-Hodgkin lymphoma treatment at the Department of Hematol. in Tenri Hospital from Sept. 2018 to Sept. 2020. Twenty-five patients were included (13 men and 12 women) and their median age was 68 (49 – 81 years). Nine (36%) of these patients developed IR (grade ≥ 2). Comparison of patient characteristics between IR and non-IR groups showed that the incidence of IR during obinutuzumab administration was related to soluble interleukin-2 receptor (sIL-2R) and lactate dehydrogenase (LDH) levels. The results of ROC curve anal. revealed the cut-off values of sIL-2R and LDH were 3,201 U/mL and 260 U/L, resp., and AUC of ROC curve for sIL-2R and LDH were estimated at 0.75 and 0.72, resp. The higher IR incidence was detected when sIL-2R levels exceeded 3.201 U/mL. In addition, the number of patients who developed IR at sIL-2R ≥ 3,201 U/mL and/or LDH ≥ 260 U/L was larger than that at sIL-2R ≥ 3,201 U/mL. The combined biomarker, SIL-2R and LDH may be useful for prediction of the occurrence of IR after the initial administration of obinutuzumab.

In patients with relapsed/refractory (R/R) Hodgkin lymphoma (HL), achieving a complete metabolic response (CMR) after salvage therapy is associated with superior outcomes, and optimal treatments must be identified. The combination of brentuximab vedotin and bendamustine (BVB), although highly active in adult patients, has not been extensively evaluated in pediatric patients with R/R HL. We performed a multicenter, retrospective review of pediatric patients <21 years of age with R/R HL treated with BVB from Jan. 2016 through July 2019. Response was assessed by local radiologists according to Lugano classification criteria. Twenty-nine patients (17 relapsed, 12 refractory) with a median age of 16 years (range, 10-20) were treated with BVB and received a median of 3 cycles of therapy (range, 2-7). Patients received an infusion of 1.8 mg/kg of BV on day 1 with bendamustine 90 mg/m² on days 1 and 2 of 3-wk cycles. Nineteen patients (66) achieved a CMR (95CI, 46-82). An objective response was observed in 23 patients (objective response rate, 79; 95CI, 60-92). The most common grade 3 and 4 toxicities were hematol., and 3 patients (10) experienced grade 3 infusion reactions. Seventeen of 18 patients underwent successful mobilization and collection of stem cells. Sixteen patients (13 autologous, 3 allogeneic) received a consolidative transplant after BVB. The 3-yr post-BVB event-free and overall survival were 65(95CI, 46-85) and 89(95CI, 74-100), resp.

Hydrogel based colon targeted delivery of rabeprazole sodium was written by Kumar, Y.;Singh, B. K.;Kumar, Aadesh;Padiyar, R. S.. And the article was included in International Journal of Pharmaceutical Sciences and Research in 2018.Quality Control of Sodium 2-(((4-(3-methoxypropoxy)-3-methylpyridin-2-yl)methyl)sulfinyl)benzo[d]imidazol-1-ide The following contents are mentioned in the article:

The aim of this research was to develop controlled and sustained release formulation of hydrogel beads containing rabeprazole sodium, and to study the effects of Eudragit S100 coating on the release of rabeprazole sodium. The main objective was to develop a colon targeted drug delivery system to minimize – drug release in the upper gastro intestinal (GI) tract as well as to minimize GI adverse effects associated with NSAIDs. Alginate hydrogel beads of rabeprazole sodium were formulated by ionotropic gelation technique and the variables studied. The prepared Eudragit S100 coated hydrogel gel beads of rabeprazole sodium were characterized by determining particle size, % drug entrapment efficiency, swelling index and in-vitro release study. The mean particle size was found to be increase with the increment in concentration of sodium alginate and decrease in the concentration of calcium chloride. The % drug entrapment efficiency of the prepared hydrogel beads formulations was found in the range of 67.45 ± 0.23 to 82.89 ± 0.64. Swelling time anal. revealed higher swelling time at pH 1.2 for the coated rabeprazole sodium hydrogel beads than at pH 7.4. With the increase in polymer and CaCl2 concentration the coated hydrogel beads show slow in-vitro drug release rates in dissolution media of different pH particularly in pH 1.2 (0.1N HCl). The results clearly demonstrate that Eudragit S100 coated hydrogel beads of rabeprazole sodium prepared by ionotropic gelation technique could be successfully used as a prospective carrier for sustained drug delivery and preventing GI side effects.

Randomised trial of acid inhibition by vonoprazan 10/20 mg once daily vs rabeprazole 10/20 mg twice daily in healthy Japanese volunteers (SAMURAI pH study) was written by Takeuchi, Toshihisa;Furuta, Takahisa;Fujiwara, Yasuhiro;Sugimoto, Mitsushige;Kasugai, Kunio;Kusano, Motoyasu;Okada, Hiroyuki;Suzuki, Takahiro;Higuchi, Tomohiro;Kagami, Takuma;Uotani, Takahiro;Yamade, Mihoko;Sawada, Akinari;Tanaka, Fumio;Harada, Satoshi;Ota, Kazuhiro;Kojima, Yuichi;Murata, Masaki;Tamura, Yasuhiro;Funaki, Yasushi;Kawamura, Osamu;Okamoto, Yuki;Fujimoto, Kazuma;Higuchi, Kazuhide. And the article was included in Alimentary Pharmacology and Therapeutics in 2020.Formula: C18H20N3NaO3S The following contents are mentioned in the article:

Summary : Background : Vonoprazan (V), a potassium-competitive acid blocker, has a more durable acid-inhibitory effect as compared with standard-dose proton pump inhibitors (PPIs) but has not been compared with 2-4 times higher daily PPI doses administered in two divided doses. Aims : To evaluate the acid-inhibitory effect of V 10/20 mg once-daily (OD; V10/V20) vs rabeprazole (R) 10/20 mg twice-daily (BID; R20/R40) in healthy Japanese volunteers. Methods : This multicentre, randomised, open-label, two-period, crossover study compared V10 or V20 vs R20, or V20 vs R40 using three cohorts of 10 healthy Japanese adults. Within each cohort, subjects were randomised to receive V or R for 7 days and, following a washout period ≥7 days, the other treatment for 7 days. On day 6 of each period, 24-h multichannel gastric impedance-pH monitoring was performed. Percent times pH ≥ 3, ≥4 and ≥5 (pH 3, 4 and 5 holding time ratios [HTRs]) in 24 h were evaluated as primary pharmacodynamic endpoints. Results : Acid-inhibitory effect (24-h pH 3 HTR) of V20 was greater than those of R20 (91.0% vs 65.3%; P = .0049) and R40 (98.5% vs 85.9%; P = .0073). Similar results were obtained for 24-h pH 4 and 5 HTRs. V20 also achieved greater nocturnal pH 4 (91.5% vs 73.2%; P = .0319) and 5 HTRs (78.8% vs 62.2%; P = .0325) as compared with R40. One subject (20%) developed diarrhoea while receiving R40 which was considered treatment-related. Conclusions : Compared with 2-4 times the standard daily dose of R, V20 exerts a more potent and durable acid-inhibitory effect. Trial identifier: UMIN000022198 (). 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: 117976-90-6Formula: C18H20N3NaO3S).

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 derivatives generally have good solubility in protic solvents. Simple imidazole derivatives, such as 1H-imidazole, 2-methyl-1H-imidazole, and 1,2-dimethylimidazole, have very high solubility in water. The pharmacophore of imidazole exists in bioactive compounds including amino acids, plant growth regulators and therapeutic agents.n increase of the alkyl chain length of the alcohols. Formula: C18H20N3NaO3S
