Proton pump inhibitors (PPIs) are the drugs of choice for treating gastroesophageal reflux disease (GERD). Their superiority to histamine2 receptor antagonists (H2RAs), cisapride, and sucralfate is directly related to their potent and prolonged suppression of gastric acid. The PPIs provide the most rapid relief of GERD symptoms and esophageal healing when compared with standard- or high-dose H2RAs or cisapride. Their superiority over H2RAs has also been demonstrated when used in maintaining esophageal healing and symptom relief. The cost effectiveness of standard-dose PPIs in the treatment of GERD has been well documented. High-dose PPI therapy may benefit patients with atypical GERD symptoms and may also be cost effective. Four PPIs are available in the United States: omeprazole, lansoprazole, rabeprazole, and pantoprazole. All 4 PPIs, when used in recommended dosages, are very effective for the acute and chronic treatment of GERD and demonstrate similar short- and long-term safety profiles. Subtle differences appear to exist, some of which are based on data obtained in vitro or from healthy volunteer studies and others on trends or relatively minor differences observed in selective clinical trials. In most cases, experience has not yet confirmed the clinical importance of these potential differences. The selection of a preferred PPI for a hospital or managed care formulary will most likely be based on the acquisition cost of the drug.

Reflux of the duodenal contents with gastric acid has been reported to contribute to the development of esophageal mucosal damage and inflammation. Recent studies show that pancreatic trypsin can stimulate the production of inflammatory mediators, including chemokines and prostaglandins from human esophageal epithelial cells in vitro. The aim of the present study was to investigate the role of pancreatic trypsin in the pathogenesis of chronic esophageal inflammation induced by gastroduodenal reflux in rats.

In the article the results of the eradication therapy by Pariet in the patients suffering from the duodenal ulcer disease, associated with Helicobacter pylori (HP), are estimated. Four schemas with use 40 and 20 mg of Pariet per day in a combination with two antibacterial preparations were evaluated. The therapy duration was 7 days. The ulcer cicatrisation has occurred in 100% of the patients. The eradication was achieved in 100% of cases at use of a dose 40 mg of Pariet per day. At use of the schemas with a dose 20 mg of Pariet per day the eradication was observed in 67% of patients. Pariet is considered as the high efficient preparation in the eradication and cicatrisation of the ulcer.

Proton pump inhibitors are used at different dosages for the treatment of acid-related gastrointestinal disorders, such as gastro-oesophaeal reflux and peptic ulcer disease. Comparisons of four different proton pump inhibitors: lansoprazole, omeprazole, pantoprazole, and rabeprazole show that they all have similar potency and efficacy. Rabeprazole, however, displays a slightly more rapid onset of acid inhibition than the others; the clinical advantage of this seems limited. The S-isomer of omeprazole, esomeprazole, exhibits a somewhat higher potency than the other proton pump inhibitors. Reports supporting a clinical advantage of this property are not convincing. To conclude, all inhibitors seem comparable as regards inhibition of gastric acid secretion.
Hiccups are a benign physiological feature affecting almost everyone at one time or another. They tend to be short-lived and do not affect quality of life; however, there are various pathologies that may present with long-lasting hiccups. These are grouped into 3 categories according to their duration: acute, persistent and intractable or protracted hiccups. Intractable hiccups last longer than 2 months and are usually associated with more severe conditions. The association between intractable hiccups and reflux disease has not been previously documented by objective methods. This report describes the case of a 23-year-old female who presented with protracted hiccups; all other organic pathologies were ruled out, and endoscopy and conventional pH-metry confirmed a diagnosis of non-erosive reflux disease as the unique cause.

Fifty-seven healthy subjects were randomly assigned groups given the cyclooxygenase (COX) 2 inhibitor celecoxib (200 mg, twice daily) plus placebo for 2 weeks (COX-2 + placebo group, n = 30), or celecoxib plus the PPI rabeprazole (20 mg, once daily) for 2 weeks (COX-2 + PPI group, n = 27). The study was performed from October 2012 through September 2013 at a tertiary medical center in Japan. All subjects were evaluated by capsule endoscopy at the start of the study and then after 2 weeks administration of celecoxib with rabeprazole or placebo. The incidence rates and the numbers of small bowel injuries (ulcers and erosions) that were observed under capsule endoscopy were compared between groups. The primary endpoint was the incidence of mucosal injuries at the second capsule endoscopy examination.

As inhibitors of organic cation transporters (OCTs), proton pump inhibitors (PPIs) may affect the plasma levels of metformin, an OCT substrate. We investigated the effects of two PPIs, pantoprazole and rabeprazole, on metformin pharmacokinetics and glucose levels in healthy subjects. In this open, randomized, six-sequence, three-period crossover study, 24 participants were administered metformin, either alone or in combination with pantoprazole or rabeprazole. The plasma concentrations of metformin and serum concentrations of glucose after a 75-g oral glucose tolerance test (OGTT) were determined. The area under the concentration-time curve (AUC) for metformin was 15% and 16% greater following coadministration with pantoprazole and rabeprazole, respectively. The maximum plasma metformin concentrations (Cmax) also increased by 15% and 22%, respectively, compared with when it was administered without the PPIs. The percentage change in the AUC for glucose concentration versus time for metformin plus rabeprazole was significantly lower than that for metformin plus pantoprazole [geometric mean ratio: 0.96 (90% confidence interval: 0.92-0.99) and 0.77 (0.63-0.93), respectively]. There was no significant difference in the maximum glucose concentration. In conclusion, concomitant administration of PPIs with metformin significantly increased plasma metformin exposure, but the effects on glucose disposition were minor and varied depending on the PPI administered.
