Gastroesophageal reflux disease is considered to be caused primarily by gastric juice refluxed into the esophagus. Here, we investigated the possible involvement of host defense mechanisms in the development of acute reflux esophagitis using lafutidine, a histamine H(2) receptor antagonist (H(2)RA) with proven gastric mucosal protective effects.

We report a case study of a 54-year-old Japanese woman who persistently suffered from a sour-taste sensation in her mouth for 10 years, and was treated with a proton-pump inhibitor (PPI). She found sour-tasting meals irritable, and after eating such meals the sour-taste sensation worsened. She also complained of eructation and regurgitation. Upper gastrointestinal (GI) endoscopy showed duodenal erosion, superficial gastritis, and erosive oesophagitis. After 2 weeks of PPI therapy (lansoprazole, 30 mg day(-1)) the sour taste subjectively decreased to 70%, and after 6 weeks the symptoms disappeared. In addition to increased sensitivity of the mouth, gastro-oesophageal reflux might have created her obstinate sour-taste sensations. It is suggested that in such cases PPI therapy should be attempted.

One hundred and sixty patients were analyzed using ITT analysis. One hundred and fifty-three patients completed the study. In group A, H. pylori eradication was achieved in 48 (60%) of the 80 patients included in the ITT analysis, and in 48 (64%) of the 75 patients included in the PP analysis. In group B, H. pylori eradication was achieved in 73 (91.25%) of the 80 included in the ITT analysis and in 73 (93.5%) of the 78 patients included in the PP analysis. The eradication rate was significantly higher in group B than in group A (p < .005). TAC was at the lower limit of normal in both groups and the difference between them was not statistically significant (p > .05).
The purpose of this study was to compare the bioavailability of lansoprazole granules administered in 2 types of juice and a soft food with that of the intact capsule administered with water.
Proton-pump inhibitors remain the most effective treatment for relieving symptoms, healing lesions and preventing recurrences of gastroesophageal reflux (GER). Drugs inhibiting transient relaxation of the lower esophageal sphincter have an unfavorable benefit/risk ratio. Endoscopic methods developed in recent years have not been shown effective in trials versus sham procedures. Surgical treatment is effective in GER but causes frequent uncomfortable side effects that are difficult to treat.

The strategies that have been proposed for the pharmacological treatment of GERD in children are primarily based on studies of case series or on studies with adults. There have been very few controlled and randomized studies in children. Undertaking a greater number of these studies might reinforce existing aspects or establish new aspects of management.

Fifty-two percent of the surveys were returned. There was no statistically significant difference between median total symptom scores for omeprazole and lansoprazole (1.33 vs. 1.34, respectively). More patients reported side effects to lansoprazole (P < 0.001) than to omeprazole. Sixty-four percent of patients preferred omeprazole (P < 0.005). The formulary conversion was estimated to save $29,000 per year.

Moderate evidence was found to support the use of PPIs, along with some evidence to support the use of H₂ antagonists in older children with GORD, based on improvement in symptom scores, pH indices and endoscopic/histological appearances. However, lack of independent placebo-controlled and head-to-head trials makes conclusions as to relative efficacy difficult to determine. Further RCTs are recommended. No robust RCT evidence is available to support the use of domperidone, and further studies on prokinetics are recommended, including assessments of erythromycin.Pharmacological treatment of infants with reflux symptoms is problematic, as many infants have GOR, and little correlation has been noted between reported symptoms and endoscopic and pH findings. Better evidence has been found to support the use of PPIs in infants with GORD, but heterogeneity in outcomes and in study design impairs interpretation of placebo-controlled data regarding efficacy. Some evidence is available to support the use of Gaviscon Infant(®) , but further studies with longer follow-up times are recommended. Studies of omeprazole and lansoprazole in infants with functional GOR have demonstrated variable benefit, probably because of differences in inclusion criteria.No robust RCT evidence has been found regarding treatment of preterm babies with GOR/GORD or children with neurodisabilities. Initiation of RCTs with common endpoints is recommended, given the frequency of treatment and the use of multiple antireflux agents in these children.

This was a phase I, open-label, non-randomized, two-period crossover study in 20 healthy subjects aged 18-55 years. Subjects received a single oral dose of ponatinib 45 mg alone on day 1, an oral dose of lansoprazole 60 mg on day 14, and ponatinib 45 mg plus lansoprazole 60 mg on day 15.
There was a significant reduction (p<0.001) in the volume of blood removed annually before (2.5 (0.25) l) and while taking (0.5 (0.25) l) a PPI. Administration of a PPI for 7d suppressed absorption of non-haem iron from the meal as shown by a significant reduction (all p<0.01) in: area under the serum curve (2145 (374) versus 1059 (219)), % recovery of administered iron at peak serum iron (20.5 (3.2) versus 11.0 (2.0)%) and peak serum iron (13.6 (2.4) vs 6.1 (1.2) micromol/l) (all values are before vs during PPI).
Patients discharged between August 2008 and July 2009 with a diagnosis of ACS, on both clopidogrel and any PPI, were identified using the pharmacy database. Their notes were retrospectively reviewed, the indication for a PPI was checked and whether an appropriate one had been prescribed was assessed. As a result of our findings a simple algorithm was introduced to set out guidance on appropriate use and junior doctors were informed of the new procedure. We then performed another audit of patients discharged between August 2009 and February 2010 to ensure that the guidelines were being followed.
The clinical presentation of Zollinger-Ellison syndrome was similar to prior reports. Acid hypersecretion was controlled in all patients with variable doses of lansoprazole. Long-term survival was principally related to underlying co-morbidity.

Over the 24-month study period from January 1, 2005, through December 31, 2006, the total numbers of PPI fills and PPI users increased by 8.5% and 9.0%, respectively, and the number of esomeprazole users decreased by 4.6%. Of esomeprazole users, the percentages of individuals obtaining esomeprazole from military pharmacies and community pharmacies, respectively, decreased from 1.7% to 1.1% and from 89.7% to 81.7%, while the percentage of individuals obtaining esomeprazole from the mail-order pharmacy increased from 8.8% to 17.6%. Time series analysis yielded a positive, statistically significant growth in esomeprazole fills (beta1=0.114; P=0.012) during the 6-month pre-intervention period (January through June 2005) and a significant reduction in August 2005 (beta2=-5.0%; P<0.001), the month immediately following the formulary change. During the 17-month post-intervention period (August 2005 through December 2006), no statistically significant change in trend for esomeprazole fills (beta3=-0.0265; P=0.534) was observed, although a small increase in the raw number of esomeprazole fills was noted. Among the 117,801 existing esomeprazole users, 86,386 (73.3%) continued using esomeprazole, 17,676 (15.0%) switched to other prescription PPIs, 679 (0.6%) used only non- PPI prescription therapy, and 13,060 (11.1%) discontinued all prescription acid-reducing pharmacotherapy after the formulary change. Significantly higher PPI switching and acid-reducing therapy discontinuation rates were observed among men aged 18-44 years and in TRICARE enrollees relative to women, those over 45 years of age, and those who used other health insurance (P<0.001). Individuals who used military pharmacies, where a PA requirement was implemented, were more likely to change pharmacy settings to obtain esomeprazole (43.8%) than were users of community pharmacies (11.9%) or the mail-order pharmacy (22.8%). Mail-order pharmacy users were less likely to discontinue acid-reducing pharmacotherapy (4.9%) than were community (11.9%) or military (12.9%) pharmacy users (P<0.05).

Two post hoc analyses were performed. Analyses included pooled data from randomized, double-blind, multicenter studies of proton pump inhibitors (PPIs) in GERD patients.
prevacid 24hr dosage
Proton pump inhibitor (PPI) is the first-line drug for GERD and is far more effective than H2-receptor antagonist (H2RA). H2RA suppresses mainly nocturnal gastric acid secretion from parietal cells, while PPI blocks acid production at nighttime as well as daytime when acid refluxes often occur. PPI-test is a therapeutic diagnosis and can reliably distinguish GERD from other diseases presenting similar symptoms. Initial therapy of GERD should be started with a full dose of PPI. However, most of the GERD patients need maintenance therapy. The maintenance dose of PPI should be individualized with a titration technique ('New Step-down therapy'). A small number of GERD patients resistant to PPI therapy may be due to nocturnal acid breakthrough (NAB) or rapid metabolism of PPI (extensive metabolizer for CYP2C19).

A series of 35 children (median age: 7.6 years, range: 3-15) with oesophagitis refractory to H2 receptor antagonists received a 12-week therapeutic course with lansoprazole. Prior to the study children underwent symptomatic and endoscopic assessment, oesophageal manometry and 24-hour intragastric and intra-oesophageal pH test. The latter was repeated after one week of therapy while patients were on treatment in order to monitor the degree of acid suppression and adjust the dose of the drug. Symptomatic assessment and endoscopy were repeated at the end of the trial
