Forty-one of 385 patients (11%) reported GERD symptoms on the Global Overall Symptom (GOS) questionnaire. Multivariate logistic regression analysis identified the independent prognostic factors for GERD symptoms as a history of gastric ulcer and use of sevelamer hydrochloride or calcium polystyrene sulfonate. Participants with GERD symptoms completed the Quality of Life in Reflux and Dyspepsia, Japanese version (QOLRAD-J) questionnaire and were assigned to receive 4-week esomeprazole treatment (20 mg/day). This PPI therapy significantly improved all QOLRAD-J domains in the full analysis set (n = 28) and improved the GERD symptoms listed in the GOS questionnaire. Significantly impaired disease-specific quality of life (QOL) in the QOLRAD-J domains was observed in 44.4-74.1% of patients who had symptoms before treatment. The mean GOS and QOLRAD-J scores correlated significantly.

Rabeprazole (40 mg) is a better choice for mild-to-moderate GERD compared with esomeprazole (40 mg) because of its better efficacy and safety profile.
Eighty consecutive dyspeptic patients with positive (13)C-urea breath test never treated were randomly allocated into group A(1) (40 patients) and group B(1) (39 patients). Eighty-three patients already treated unsuccessfully with positive (13)C-urea breath test were divided into group A(2) (51 patients) and group B(2) (32 patients). Patients in group A(1) and group A(2) underwent upper gastrointestinal endoscopy for H. pylori susceptibility test to amoxicillin, clarithromycin, tinidazole, rifabutin, and levofloxacin. These patients were treated with levofloxacin (500 mg b.i.d.), amoxicillin (1 g b.i.d.) and esomeprazole (20 mg b.i.d.) for 10 days if sensitive to these two antibiotics. If H. pylori was found resistant to amoxicillin and/or levofloxacin the treatment was based on the indications of the susceptibility test. Patients in group B(1) and group B(2) were treated empirically with levofloxacin, amoxicillin, and esomeprazole at the same dose and duration as group A. All patients underwent (13)C-urea breath test 2 months after the end of therapy.

For this state employee health plan, the policy change that excluded esomeprazole from coverage but grandfathered current users was associated with a relatively small reduction in PMPM spending on PPIs compared with the subsequent policy change that applied reference pricing to the PPI class based on the price (drug cost plus dispensing fee) for omeprazole OTC. Over 43 months of reference pricing, net plan costs fell dramatically by 49.5% PMPM compared with the preperiod or decreased by 43.5% compared with the esomeprazole-exclusion period. While utilization was essentially unchanged compared with the 18 months before reference pricing, the average pharmacy dispensing fee per PPI claim increased, and beneficiary costs PMPM decreased.

In all groups there was a decrease in the AUC(0-24) when carbamazepine was coadministered with esomeprazole. The decrease in AUC(0-24) (22.78 ± 4.71 to 10.46 ± 2.29), C(max) (2.76 ± 0.77 to 1.412±1.08), T(max) (2.83 ± 0.17 to 3 ± 0.40) was statistically significant (P < 0.05) when esomeprazole was given along with carbamazepine. Additionally, absorption and elimination constant were also altered significantly.
Esomeprazole analogs are a class of important proton pump inhibitors for the treatment of gastro-esophageal reflux diseases. Understanding the fragmentation reaction mechanism of the protonated esomeprazole analogs will facilitate the characterization of their complex metabolic fate in humans. In this paper, the kinetic method and theoretical calculations were applied to evaluate the fragmentation of protonated esomeprazole analogs.

The fixed-dose acetylsalicylic acid (ASA)/esomeprazole capsule combines the cardiovascular (CV) protective effects of low-dose ASA with the gastroprotective effects of the proton pump inhibitor esomeprazole. It is approved for use as a convenient once-daily regimen in the prevention of CV and cerebrovascular events in patients requiring continuous low-dose ASA who are at risk of developing gastric and/or duodenal (peptic) ulcers. In two large, 26-week, randomized, double-blind, multinational, phase III trials (ASTERIX and OBERON) in patients who were receiving low-dose ASA for the prevention of CV events and who had an increased risk of ulcer development, the incidence of endoscopy-proven peptic ulcers (primary endpoint) was significantly lower with the addition of esomeprazole 20 mg/day versus placebo. Moreover, patient-reported dyspeptic symptoms (epigastric pain and epigastric burning) were reported in significantly fewer patients in the low-dose ASA plus esomeprazole group than in the low-dose ASA plus placebo group. Low-dose ASA plus esomeprazole treatment was generally well tolerated, with a similar adverse event profile to that seen with low-dose ASA plus placebo.
The study included 31 children (17 boys, 14 girls; mean age, 5 years; 18 children in the younger group, 13 in the older group). A total of 27 children were included in the PK analysis. In the younger group, the geometric mean AUC(0-infinity) and Cmax values in the esomeprazole 10-mg group were >2-fold that in the 5-mg group (AUC(0-infinity), 4.83 and 0.74 pmol x h/L [0.32 and 0.04 micromol x h x L(-1)/kg], respectively; Cmax, 2.98 and 0.62 micromol/L [0.19 and 0.03 micromol/L x kg(-1)], respectively). In the older group, the geometric mean AUC(0-infinity) and Cmax values for the 20-mg dose group were approximately 2-fold those for the 10-mg dose group (AUC(0-infinity), 6.28 and 3.70 micromol x h/L [0.21 and 0.12 pmol x h x L(-1)/kg], respectively; Cmax, 3.73 and 1.77 micromol/L [0.13 and 0.06 micromol/L x kg 1], respectively). For the 10-mg esomeprazole dose, the geometric mean body-weight-normalized apparent oral clearance was approximately 50% higher in the younger group compared with the older group (0.40 and 0.25 L/h x kg(-1), respectively). Thirty patients were included in the tolerability analysis. The adverse events that occurred were skin excoriation, discolored feces, and skin laceration (1 [3.3%] patient each); none were considered related to treatment.
Twenty patients (mean age of 48.95 ± 18.69, age range 20-81 years) were enrolled. Esophageal acid exposure parameters, during recumbent-awake, recumbent-asleep, and conscious awakenings were significantly improved on last day of treatment as compared to baseline (p < 0.05). However, the frequency and duration of conscious awakenings and duration of recumbent-awake period did not improve as compared to baseline (p > 0.05).

Several frequently used PPIs previously thought to be safe for concomitant use with clopidogrel were associated with greater risk of adverse cardiovascular events. Although the data are observational, they highlight the need for randomized controlled trials to evaluate the safety of concomitant PPI and clopidogrel use in patients with coronary artery disease.

To evaluate if esomeprazole prevents recurrent peptic ulcer in adult patients with a history of peptic ulcer receiving low-dose acetylsalicylic acid (ASA, aspirin) for cardiovascular protection in East Asia.
The acidity of the gastric juice changed in the range over pH 5 during the 24 hours by the application of esomeprazole. Fibrogastroscopic examinations were performed of patients who were found to have fresh erythrocytes in the gastric contents. No one was registered with bleeding of the gastric mucous. The isolated microorganisms of the gastric juice and wash away of mouth cavity were identical with those of tracheobronchial aspiration in about 13 %.

nexium 60 mg
All 342 patients (191 males), aged 19-79 (mean 49) years, were evaluable in the intention-to-treat analysis. The proportion of patients who discontinued treatment due to insufficient control of heartburn was significantly higher among placebo compared to esomeprazole recipients (51% vs. 14%; P < 0.0001). Patients randomized to esomeprazole on-demand therapy remained in the study longer than those in the placebo group (mean 165 vs. 119 days). Over 50% took the study medication for periods of 1--3 consecutive days (esomeprazole) or 4--13 consecutive days (placebo). Use of antacids was > 2-fold higher among placebo recipients. The frequency of adverse events was similar in the two groups, when adjusted for time spent in the study, as were the clinical laboratory profiles.
