Patients with Rockall scores ≥6 have an increased risk of long-term peptic ulcer rebleeding. This study was aimed toward investigating whether an extended course of oral esomeprazole up to 1 year decreased ulcer rebleeding in such patients.. We prospectively enrolled 120 patients with peptic ulcer bleeding and Rockall scores ≥6. After an initial 16-week oral proton pump inhibitor (PPI) treatment, patients were randomized to receive a 36-week course of oral twice-daily esomeprazole 20 mg (Group D, n = 60) or once-daily (Group S, n = 60). Thereafter, they were divided into the PPI-on-demand (n = 32) and PPI-discontinued (n = 77) subgroups. Our previous cohort with Rockall scores ≥6 served as the controls (Group C, n = 135); they received only an initial 8- to 16-week oral PPI. The primary and secondary outcomes were peptic ulcer rebleeding during the first year and the second year-and-thereafter, respectively.. For the primary outcome, groups D and S comprised a higher proportion of rebleeding-free than Group C (P = 0.008 and 0.03, log-rank test). The competing-risks regression analysis confirmed that extended PPI use and American Society of Anesthesiologists classification were independent factors contributing to the primary outcome. For the secondary outcome, PPI-on-demand had a borderline higher proportion of rebleeding-free than Group C (P = 0.07, log-rank test); however, only the Rockall score was the independent factor.. An extended 36-week course of oral esomeprazole 20 mg, twice- or once-daily for patients with Rockall scores ≥6 reduced ulcer rebleeding during the first year, but the effect needed to be further validated when PPIs were shifted to on-demand or discontinued thereafter (NCT02456012, 28/05/2015).

Endoscopic submucosal dissection (ESD) is a standard procedure for treating gastric neoplasms. However, ESD causes larger artificial ulcers other than mucosal resection methods. We conducted this prospective randomized controlled study to evaluate the effect of stronger acid suppression on ESD ulcers caused by doubling the proton pump inhibitor (PPI) dose and compare the effects of 20-mg (standard dose) and 40-mg (double dose) esomeprazole (EswonampTM, Daewon Pharmaceutical Co., Ltd., Seoul, Korea) on ulcer healing.. One hundred ninety-seven patients who underwent gastric ESD from July 2017 to December 2017 at Pusan National University Yangsan Hospital were enrolled and randomly assigned to the standard or double-dose group. Change in ulcer size from the day of ESD to 4 weeks after ESD and the scar-change rate were compared between the groups.. There were no significant differences in ulcer contraction (84.5% in 20 mg group vs 86.3% in 40 mg group, P = .91) or scar-change rate (30.9% vs 30.6%, P > .99) between the groups. In a multivariate analysis, initial ulcer size [odds ratio (OR) 0.24; 95% confidence interval (CI) 0.11-0.50] and early gastric cancer (OR 0.22, 95% CI 0.08-0.58) were significantly associated with delayed ulcer healing.. Both 40 and 20-mg esomeprazole have similar effects on ESD-induced ulcer area reduction, suggesting that strong acid suppression does not necessarily result in rapid artificial ulcer healing..

To investigate the optimum period of treatment for post endoscopic submucosal dissection (ESD) ulcers.. Patients who underwent ESD for gastric cancer were randomized to two groups and treated with esomeprazole 20 mg per day for 4 wk (4W group) or 2 wk (2W group). At 4 wk after ESD, we measured the size of the artificial ulcers by endoscopy and determined the ulcer healing rate, compared with the size of the ESD specimens. This randomized controlled trial study was approved by our ethics committee and registered in the UMIN Clinical Trial Registry.. A total of 60 consecutive patients were included in the study. All patients received rebamipide 300 mg per day for 4 wk. One patient in 2W group who showed bleeding within two weeks and received endoscopic treatment was excluded from further analysis. The numbers of patients with ulcers in the healing/scar stage in the 2W and 4W groups at 4 wk after ESD were 20/6 and 28/5, respectively, with no significant difference. The ulcer healing rate in the 2W and 4W groups were 96.1% [95% confidence interval (CI): 94.6%-97.55] vs 94.8% (95%CI: 92.6%-97.1%), respectively, with no statistical difference (UMIN000006951).. Two-wk treatment with a proton pump inhibitor is as effective as four-week treatment for healing post ESD ulcers.

Recently, prednisolone has been used in treating many medical conditions, such as autoimmune diseases and cancer. It is also prescribed to mitigate the respiratory complications caused by COVID-19 infection. It can cause some health complications, such as GIT ulcers, so it should be co-administered with proton-pump inhibitors, such as esomeprazole, to prevent the risk of ulcers. This work aims to develop an ecofriendly and sensitive TLC method for simultaneous determination of esomeprazole and prednisolone in their binary mixtures and spiked human plasma. Separation was performed using a mixture of ethyl acetate, methanol, and ammonia (9.5:0.5:0.1, v/v/v) as an eluting system with UV scanning at 245 nm. Dapoxetine was used as an internal standard to correct the variation during sampling. The resulting R

Objective: The present study aimed to develop and optimize esomeprazole loaded proniosomes (EZL-PNs) to improve bioavailability and therapeutic efficacy. Method: EZL-PNs formulation was developed by slurry method and optimized by 33 box-Bhekhen statistical design software. Span 60 (surfactant), cholesterol, EZL concentration were taken as independent variables and their effects were evaluated on vesicle size (nm), entrapment efficiency (%, EE) and drug release (%, DR). Furthermore, optimized EZL-PNs (EZL-PNs-opt) formulation was evaluated for ex vivo permeation, pharmacokinetic and ulcer protection activity. Result: The EZL-PNs-opt formulation showed 616 ± 13.21 nm of vesicle size, and 81.21 ± 2.35% of EE. EZL-PNs-opt exhibited negative zeta potential and spherical confirmed scanning electron microscopy. EZL-PNs-opt showed sustained release of EZL (95.07 ± 2.10% in 12 h) than pure EZL dispersion. The ex-vivo gut permeation result exhibited a significantly (p < 0.05) enhanced flux than pure EZL. The in vivo results revealed 4.02-fold enhancement in bioavailability and 61.65% protection in ulcer than pure EZL dispersion (43.82%). Conclusion: Our findings revealed that EZL-PNs formulation could be an alternative delivery system of EZL to enhance oral bioavailability and antiulcer activity.

Endoscopic submucosal dissection (ESD) is widely used as a treatment modality for gastric mucosal neoplasia. While proton pump inhibitors (PPIs) have been used for the control of artificial ulcers created by ESD (ESD-ulcers), complete healing of the ulcers is not always achieved in all the cases. The purpose of this study was to identify the clinical factors that are predictive of refractory ESD-ulcers.. We recruited 90 patients with 102 artificial ulcers that formed after the patients underwent ESD for gastric tumours. All the patients received a 20-mg capsule of esomeprazole daily until the 56th day after ESD, and underwent endoscopy at 1, 4, 6 and 8 weeks after the ESD. We analyzed the clinical factors that were associated with the complete healing at 8 weeks after the ESD (CH-8w). The ulcers in the scar stage were defined as the complete healing in this study.. Of the 102 ESD-ulcers, 16.7% failed to show complete healing after the 8 weeks of PPI therapy. Univariate analysis identified the percent reduction of the ulcer size at 4 weeks after ESD (PR-4w) as being significantly associated with CH-8w. Multivariate analysis identified ulcer location in the lower-third of the stomach and PR-4w > 95% as being independently correlated with the CH-8w (odds ratio = 4.86 and 7.89, respectively). Analysis of the area under the receiver operating characteristic (AUROC) curve demonstrated that the AUROC curve of PR-4w for predicting the CH-8w was 0.78.. Based on the results of our study, endoscopic observation at 4 weeks after ESD would help in the early identification of refractory ESD-ulcers.
