Abstract
Gastro-oesophageal reflux disease (GERD) is a common disorder in adults and children. The global prevalence of GERD is high and increasing. Non-erosive reflux disease is the most common phenotype of GERD. Heartburn and regurgitation are considered classic symptoms but GERD may present with various atypical and extra-oesophageal manifestations. The pathophysiology of GERD is multifactorial and different mechanisms may result in GERD symptoms, including gastric composition and motility, anti-reflux barrier, refluxate characteristics, clearance mechanisms, mucosal integrity and symptom perception. In clinical practice, the diagnosis of GERD is commonly established on the basis of response to anti-reflux treatment; however, a more accurate diagnosis requires testing that includes upper gastrointestinal tract endoscopy and reflux monitoring. New techniques and new reflux testing parameters help to better phenotype the condition. In children, the diagnosis of GERD is primarily based on history and physical examination and treatment vary with age. Treatment in adults includes a combination of lifestyle modifications with pharmacological, endoscopic or surgical intervention. In refractory GERD, optimization of proton-pump inhibitor treatment should be attempted before a series of diagnostic tests to assess the patient's phenotype.

Abstract
Management of gastroesophageal reflux disease (GERD) commonly starts with an empiric trial of proton pump inhibitor (PPI) therapy and complementary lifestyle measures, for patients without alarm symptoms. Optimization of therapy (improving compliance and timing of PPI doses), or increasing PPI dosage to twice daily in select circumstances, can reduce persistent symptoms. Patients with continued symptoms can be evaluated with endoscopy and tests of esophageal physiology, to better determine their disease phenotype and optimize treatment. Laparoscopic fundoplication, magnetic sphincter augmentation, and endoscopic therapies can benefit patients with well-characterized GERD. Patients with functional diseases that overlap with or mimic GERD can also be treated with neuromodulators (primarily antidepressants), or psychological interventions (psychotherapy, hypnotherapy, cognitive and behavioral therapy). Future approaches to treatment of GERD include potassium-competitive acid blockers, reflux-reducing agents, bile acid binders, injection of inert substances into the esophagogastric junction, and electrical stimulation of the lower esophageal sphincter.

Abstract
As an increase in gastroesophageal reflux disease (GERD) has been reported in Japan, and public interest in GERD has been increasing, the Japanese Society of Gastroenterology published the Evidence-based Clinical Practice Guidelines for GERD (1st edition) in 2009. Six years have passed since its publication, and there have been a large number of reports in Japan concerning the epidemiology, pathophysiology, treatment, and Barrett's esophagus during this period. By incorporating the contents of these reports, the guidelines were completely revised, and a new edition was published in October 2015. The revised edition consists of eight items: epidemiology, pathophysiology, diagnosis, internal treatment, surgical treatment, esophagitis after surgery of the upper gastrointestinal tract, extraesophageal symptoms, and Barrett's esophagus. This paper summarizes these guidelines, particularly the parts related to the treatment for GERD. In the present revision, aggressive proton pump inhibitor (PPI) maintenance therapy is recommended for severe erosive GERD, and on-demand therapy or continuous maintenance therapy is recommended for mild erosive GERD or PPI-responsive non-erosive GERD. Moreover, PPI-resistant GERD (insufficient symptomatic improvement and/or esophageal mucosal break persisting despite the administration of PPI at a standard dose for 8 weeks) is defined, and a standard-dose PPI twice a day, change in PPI, change in the PPI timing of dosing, addition of a prokinetic drug, addition of rikkunshito (traditional Japanese herbal medicine), and addition of histamine H2-receptor antagonist are recommended for its treatment. If no improvement is observed even after these treatments, pathophysiological evaluation with esophageal impedance-pH monitoring or esophageal manometry at an expert facility for diseases of the esophagus is recommended.

Abstract
BACKGROUND Patients have been given magnesium to treat or prevent alcohol withdrawal syndrome (AWS). Evidence to support this practice is limited, and is often based on the controversial link between hypomagnesaemia and AWS. OBJECTIVES To assess the effects of magnesium for the prevention or treatment of AWS in hospitalised adults. SEARCH METHODS We searched the Cochrane Drugs and Alcohol Group Register of Controlled Trials (August 2012), PubMed (from 1966 to August 2012 ), EMBASE (from 1988 to August 2012), CINAHL (from 1982 to March 2010), Web of Science (1965 to August 2012). We also carried out Internet searches. SELECTION CRITERIA Randomised or quasi-randomised trials of magnesium for hospitalised adults with, or at risk for, acute alcohol withdrawal. DATA COLLECTION AND ANALYSIS Two review authors independently extracted data with a standardised data extraction form, contacting the correspondence investigator if the necessary information was not available in the reports. Dichotomous outcomes were analysed by calculating the risk ratio (RR) for each trial, with the uncertainty in each result expressed with a 95% confidence interval (CI). Continuous outcomes were to be analysed by calculating the standardised mean difference (SMD) with 95% CI. For outcomes assessed by scales we compared and pooled the mean score differences from the end of treatment to baseline (post minus pre) in the experimental and control groups. MAIN RESULTS Four trials involving 317 people met the inclusion criteria. Three trials studied oral magnesium, with doses ranging from 12.5 mmol/day to 20 mmol/day. One trial studied parenteral magnesium (16.24 mEq q6h for 24 hours). Each trial demonstrated a high risk of bias in at least one domain. There was significant clinical and methodological variation between trials.We found no study that measured all of the identified primary outcomes and met the objectives of this review. Only one trial measured clinical symptoms of seizure, delirium tremens or components of the Clinical Institute Withdrawal Assessment for Alcohol (CIWA) score. A single outcome (handgrip strength) in three trials (113 people), was amenable to meta-analysis. There was no significant increase in handgrip strength in the magnesium group (SMD 0.04; 95% CI -0.22 to 0.30). No clinically important changes in adverse events were reported. AUTHORS' CONCLUSIONS There is insufficient evidence to determine whether magnesium is beneficial or harmful for the treatment or prevention of alcohol withdrawal syndrome.

Abstract
Gastroesophageal reflux disease is increasingly associated with ear, nose, and throat symptoms, including laryngitis. Many patients are unaware of the gastroesophageal etiology of their symptoms. A variety of criteria are used to diagnose this condition, including laryngoscopy, esophagogastroduodenoscopy, and the use of ambulatory pH and impedance monitoring. However, no test serves as the gold standard for the diagnosis given their lack of sensitivity and specificity for reflux disease. Numerous trials have assessed the role of proton pump inhibitor therapy in patients with laryngopharyngeal reflux and most have revealed no benefit to acid suppression over placebo. Despite many uncertainties there has been some progress regarding the role of acid-suppressive therapy as well as other agents in this unique group of patients. In this review we explore therapeutic options and their rationale for patients with laryngeal signs and symptoms.

Abstract
Chronic consumption of proton pump inhibitors (PPIs) by patients with gastroesophageal reflux disease is very common, primarily because of their potent and profound effect on acid secretion that results in an unsurpassed rate of symptom resolution and esophageal healing. However, there have been a growing number of reports over the past few years about various side effects caused by chronic PPI treatment. Concerns have been raised by patients and physicians alike about the common practice of prescribing PPIs, often more than once daily, on a long-term basis. As a result, there has been a resurgence of interest in alternative therapeutic modalities for chronic PPI treatment. These include novel endoscopic and surgical techniques, as well as other available therapeutic strategies that are likely to be revisited, such as histamine-2-receptor antagonists, intermittent and on-demand PPI treatment, and antireflux surgery, among others.

Abstract
Gastroesophageal reflux disease (GERD) is very common and advances in drug development over recent years have markedly improved GERD management. A wide range of medications are currently used in GERD treatment, including antacids, Gaviscon, sucralfate, histamine-2 receptor antagonists and prokinetics. However, proton pump inhibitors (PPIs) remain the mainstay of treatment for GERD owing to their profound and consistent inhibitory effect on acid secretion. Despite the presence of a wide armamentarium of therapeutic modalities for GERD, many areas of unmet needs remain. Drug development has focused primarily on improving PPI efficacy, reducing the transient lower esophageal sphincter relaxation rate, attenuating esophageal sensitivity and developing esophageal mucosal protectants.

Abstract
BACKGROUND Oesophagitis arises when reflux of acid from the stomach into the oesophagus causes mucosal inflammation. It is a common problem and a systematic review on the optimum treatment would be useful. OBJECTIVES To assess the effectiveness of proton pump inhibitors (PPIs), H2 receptor antagonists (H2RAs), prokinetic therapy, sucralfate and placebo in healing oesophagitis or curing reflux symptoms or both. To compare adverse effects with the different treatments. SEARCH STRATEGY We searched MEDLINE, EMBASE, CINAHL, Cochrane Central Register of Controlled Trials and the National Research Register until December 2004 and reference lists of articles. We also contacted manufacturers and researchers in the field. SELECTION CRITERIA Randomised controlled trials assessing the healing of oesophagitis or reflux symptoms or both. Treatment involving PPIs, H2RAs, prokinetics, sucralfate and combinations either in comparison to another treatment regimen or to placebo for 2 and 12 weeks. DATA COLLECTION AND ANALYSIS Two reviews independently assessed trial quality and extracted data. MAIN RESULTS We included 134 trials involving 35,978 oesophagitis participants. Five RCTs evaluated standard dose of PPI versus placebo in 965 participants. There was a statistically significant benefit of taking standard dose PPI therapy compared to placebo in healing of oesophagitis (RR = 0.22; 95% CI 0.15 to 0.31). Ten RCTs reported on the outcome for H2RA versus placebo evaluating 1241 participants. There was statistically significant benefit of taking H2RA compared to placebo in healing of oesophagitis (RR 0.74,95% CI = 0.66 to 0.84). Three RCTs evaluated prokinetic therapy versus placebo in 198 participants. There was no statistically significant benefit of taking prokinetic therapy compared to placebo in healing of oesophagitis (RR 0.71, 95% CI 0.46 to 1.10). Twenty six RCTs reported the outcome for PPI versus H2RA or H2RA plus prokinetics, evaluating 4032 participants. There was statistically significant benefit of taking PPI therapy compared to H2RA or H2RA plus prokinetics in healing of oesophagitis (RR 0.51, 95% CI 0.44 to 0.59). AUTHORS' CONCLUSIONS PPI therapy is the most effective therapy in oesophagitis but H2RA therapy is also superior to placebo. There is a paucity of evidence on prokinetic therapy but no evidence that it is superior to placebo.

Abstract
Current therapies to treat gastroesophageal reflux disease (GERD), peptic ulcer disease (PUD), and other acid-related diseases either prevent stimulation of the parietal cell (H2 receptor antagonists, H2RAs) or inhibit gastric H+,K+-ATPase (e.g., proton pump inhibitors, PPIs). Of the 2 approaches, the inhibition of the final step in acid production by PPIs provides more effective relief of symptoms and healing. Despite the documented efficacy of the PPIs, therapeutic doses have a gradual onset of effect and do not provide complete symptom relief in all patients. There is scope for further improvements in acid suppressive therapy to maximize healing and offer more complete symptom relief. It is unlikely that cholecystokinin2 (CCK2, gastrin) receptor antagonists, a class in clinical trials, will be superior to H2RAs or PPIs. However, a new class of acid suppressant, the potassium-competitive acid blockers (P-CABs), is undergoing clinical trials in GERD and other acid-related diseases. These drugs block gastric H+,K+-ATPase by reversible and K+-competitive ionic binding. After oral doses, P-CABs rapidly achieve high plasma concentrations and have linear, dose-dependent pharmacokinetics. The pharmacodynamic properties reflect the pharmacokinetics of this group (i.e., the effect on acid secretion is correlated with plasma concentrations). These agents dose dependently inhibit gastric acid secretion with a fast onset of action and have similar effects after single and repeated doses (i.e., full effect from the first dose). Animal studies comparing P-CABs with PPIs suggest some important pharmacodynamic differences (e.g., faster and better control of 24-hr intragastric acidity). Studies in humans comparing PPIs with P-CABs will help to define the place of this new class in the management of acid-related diseases.

Abstract
This report summarizes the conclusions and recommendations of a panel of gastroenterologists practising in the Asia-Pacific region. The group recognized that although gastroesophageal reflux disease (GERD) is less common and milder in endoscopic severity in Asia than in the West, there is nevertheless data to suggest an increasing frequency of the disease. During a 2-day workshop, the evidence for key issues in the diagnosis and clinical strategies for the management of the disease was evaluated, following which the recommendations were made and debated. The consensus report was presented at the Asia-Pacific Digestive Week 2003 in Singapore for ratification. Upper gastrointestinal (GI) endoscopy is the gold standard for the diagnosis of erosive GERD. There is no gold standard for the diagnosis of non-erosive GERD (NERD). Diagnosis therefore relies on symptoms, a positive 24-h pH study or a response to a course of proton pump inhibitor (PPI) treatment. The goals of treatment for GERD are to heal esophagitis, relieve symptoms, maintain the patient free of symptoms, improve quality of life and prevent complications. The PPI are the most effective medical treatment. Following initial treatment, on-demand therapy may be effective in some patients with NERD or mild (GI) erosive esophagitis. Anti-reflux surgery by a competent surgeon could achieve a similar outcome, although there is an operative mortality of 0.1-0.8%. The decision is dependent on the patient's preference and the availability of surgical expertise. Currently, endoscopic treatment should be performed only in the context of a clinical trial. Treatment of patients with typical GERD symptoms without alarm features in primary care could begin with PPI for 2 weeks followed by a further 4 weeks before going to on-demand therapy.

Abstract
Gastroesophageal reflux disease is a common, usually lifelong, disorder resulting from chronic abnormal exposure of the lower esophagus to gastric contents. Motor dysfunction of the lower esophageal sphincter is the primary cause of this disease. At this writing, no medical therapies can completely resolve abnormal lower esophageal sphincter function; therefore, the treatment of gastroesophageal reflux disease centers on suppression of intragastric acid secretion. Available acid-suppressant medications include proton pump inhibitors, H2-receptor antagonists, and antacids. Of these, the proton pump inhibitors are recognized generally as the mainstays of both short-term and long-term therapy for gastroesophageal reflux disease. All have a low incidence of side effects and are well tolerated by most patients. Five proton pump inhibitors are available currently for patients with gastroesophageal reflux disease. Of these, esomeprazole has shown greater efficacy in controlling intragastric acidity than the others. For patients with erosive esophagitis, esomeprazole has demonstrated higher healing rates and more rapid sustained resolution of heartburn than omeprazole or lansoprazole after up to 8 weeks of once-daily treatment. Because new therapies for gastroesophageal reflux disease are highly effective, patients can be reassured that their disease will be well controlled and their symptoms resolved with a safe and appropriate treatment.

Abstract
Since gastro-oesophageal reflux disease (GORD) is a prevalent condition characterised by frequent relapses, long-term costs of management for this disease are high. Thus, strategies to decrease resource expenditures without impairing patient quality of life are desirable. On-demand therapy (one-dose when symptoms occur) and intermittent therapy (short course of medication when symptoms occur) are attractive since pharmaceutical expenditures may be decreased, and many patients self-employ this strategy. The purpose of this paper was to examine the economic implications of on-demand or intermittent therapy for GORD. A review of selected studies evaluating medication suitable for on-demand or intermittent administration was performed. A complete search for published studies on the cost effectiveness of on-demand or intermittent therapy for GORD was conducted, and the results discussed in detail. Antacids, alginates, topically active agents, histamine(2)-receptor antagonists, and proton pump inhibitors have all demonstrable efficacy compared with placebo when administered on-demand. Proton pump inhibitors constitute the most effective pharmacological means to treat GORD. Although step-up strategies initially using less potent medication may decrease resource use, cost-effectiveness analysis illustrates that on-demand or intermittent therapy with proton pump inhibitors may be reasonable options. Further work that defines quality of life and patient preferences associated with GORD may allow for proper allocation of resources for the management of this condition.

Abstract
Antacids are commonly used self-prescribed medications. They consist of calcium carbonate and magnesium and aluminum salts in various compounds or combinations. The effect of antacids on the stomach is due to partial neutralisation of gastric hydrochloric acid and inhibition of the proteolytic enzyme, pepsin. Each cation salt has its own pharmacological characteristics that are important for determination of which product can be used for certain indications. Antacids have been used for duodenal and gastric ulcers, stress gastritis, gastro-oesophageal reflux disease, pancreatic insufficiency, non-ulcer dyspepsia, bile acid mediated diarrhoea, biliary reflux, constipation, osteoporosis, urinary alkalinisation and chronic renal failure as a dietary phosphate binder. The development of histamine H2-receptor antagonists and proton pump inhibitors has significantly reduced usage for duodenal and gastric ulcers and gastro-oesophageal reflux disease. However, antacids can still be useful for stress gastritis and non-ulcer dyspepsia. The recent release of proprietary H2 antagonists has likely further reduced antacid use for non-ulcer dyspepsia. Other indications are still valid but represent minor uses. Antacid drug interactions are well noted, but can be avoided by rescheduling medication administration times. This can be inconvenient and discourage compliance with other medications. All antacids can produce drug interactions by changing gastric pH, thus altering drug dissolution of dosage forms, reduction of gastric acid hydrolysis of drugs, or alter drug elimination by changing urinary pH. Most antacids, except sodium bicarbonate, may decrease drug absorption by adsorption or chelation of other drugs. Most adverse effects from antacids are minor with periodic use of small amounts. However, when large doses are taken for long periods of time, significant adverse effects may occur especially patients with underlying diseases such as chronic renal failure. These adverse effects can be reduced by monitoring of electrolyte status and avoiding aluminum-containing antacids to bind dietary phosphate in chronic renal failure. Antacids, although effective for discussed indications of duodenal and gastric ulcer and gastro-oesophageal reflux disease, have been replaced by newer, more effective agents that are more palatable to patients. Antacids are likely to continue to be used for non-ulcer dyspepsia, minor episodes of heartburn (gastro-oesophageal reflux disease) and other clear indications. Although their wide-spread use may decline, these drugs will still be used, and clinicians should be aware of their potential drug interactions and adverse effects.

Abstract
More than 200 Danish randomized controlled clinical trials in gastroenterology published from 1970 to 1994 were retrieved by electronic media, by hand-searching relevant journals, and by direct requests to Danish gastroenterologists. With the historical perspective through a quarter of a century, these papers are outlined to provide a survey of the pieces of information that Danish gastroenterologists have contributed to the present knowledge of therapeutics. The presented randomized controlled clinical trials constitute an impressive sum of knowledge within a diversity of topics. A cautious analysis of the time pattern for the publications in addition to the contents of the reports discloses that the discipline of planning and executing relevant controlled clinical trials is now in blossom in Danish gastroenterology.

Abstract
Gastroesophageal reflux is a common disease. Its chronic course, even if mild, is sometimes complicated by erosive oesophagitis. Drug therapy acts against gastric acidity and motility disorders. Treatment of gastroesophageal reflux disease has three aims: improvement of symptoms and quality of life, healing erosive lesions and prevention of symptomatic and endoscopic relapses. Non-drug measures are always useful, even if their efficacy is not well established. Initial therapy of a symptomatic reflux or mild oesophagitis is most of the time effective (antacids, prokinetics, H2 receptor antagonists). Proton-pump inhibitors are also effective in healing and preventing severe oesophagitis. Questions about long-term treatment adverse events with powerful acid inhibitors, such as hypergastrinemia and the risk of gastric carcinoid tumours seem to be resolved. Studies are requested to define the optimal long-term maintenance treatment with cisapride, H2 receptor antagonists or proton-pump inhibitors at low doses in prevention of symptomatic and mild oesophagitis relapses.

Abstract
Gastro-oesophageal reflux disease (GORD) ranges from episodic symptomatic reflux without oesophagitis to severe oesophageal mucosal damage, such as Barrett's metaplasia or peptic stricture. The multifactorial pathogenesis of GORD prevents medical cure of the disease. GORD is a chronic disease with a high tendency to relapse, requiring a long term treatment strategy in practically all patients. Complete healing of all mucosal lesions is not necessarily the aim of treatment in all patients. In milder forms of reflux disease, symptom relief is the most important goal. Many patients with mild GORD do well on symptomatic self-care with antacids and/or alginate. In addition, lifestyle changes should be advised to all patients: these improve symptoms and enhance the efficacy of therapy. In the acute treatment of GORD the prokinetic drug cisapride has been shown to be effective in relieving symptoms and healing grade I to II oesophagitis. Cisapride decreases symptomatic and endoscopic relapse in patients with mild GORD. Histamine H2-receptor antagonists are effective in relieving reflux symptoms in about 50% of patients, but with regard to healing, H2-antagonists appear to be mainly effective in grades I and II and not in higher grades of oesophagitis. Maintenance treatment with H2-antagonists is mainly symptomatically effective in patients with mild GORD. Proton pump inhibitors (PPIs) provide significantly higher healing rates of reflux oesophagitis than H2-antagonists, even in the more severe cases of oesophagitis and Barrett's ulcers. PPIs are also effective in patients with oesophagitis refractory to treatment with H2-antagonists. PPIs have become the drugs of first choice in healing of all patients with more severe forms of reflux oesophagitis, and increasingly also for patients with milder forms of oesophagitis, certainly those who fail to respond to other drugs. In maintenance treatment of GORD, PPIs are the most effective drugs, offering the possibility of keeping nearly all patients in remission with adjusted doses. Current patient data of up to 5 years indicate the safety of this strategy for this period, but the exact consequences of strong acid inhibition over a longer period still have to be clarified. At present, all but a few patients with GORD can be managed adequately by medical therapy.

Abstract
BACKGROUND To ascertain the placebo-induced effect in the treatment of reflux esophagitis, we reviewed all the English-language literature concerning the results of placebo-controlled trials of erosive/ulcerative esophagitis from 1976 to 1990. Twenty-two studies fulfilled our meta-analytic criteria. RESULTS After 4 to 8 weeks of treatment, active drugs (cimetidine, ranitidine, nizatidine, omeprazole, metoclopramide, sucralfate) were significantly more effective than placebo in the healing of esophagitis, with a pooled rate difference (PRD) of 0.22 in favor of the active drug, an odds ratio (OR) of 2.57 (confidence interval (CI) = 2.0-3.3). Pooled mean healing rate (+/- SD) with the active drug was 47.3 +/- 24.0%, as compared with 26.8 +/- 18.0% obtained with placebo after 4 to 8 weeks of treatment. With regard to symptomatic response, complete disappearance of symptoms was observed in an average of 31.6% active-treated patients and in 11.8% of placebo-treated patients, respectively. The PRD was 0.20, and the OR 2.25 (CI = 1.65-3.06). The incidence of side effects was not statistically different for the two treatment groups. CONCLUSION Placebo is a relatively inactive drug in the short-term treatment of erosive ulcerative reflux and does not appear to change the natural history of the disease.

Abstract
Antacids have served us well for over a century. In terms of peptic ulcer disease, the attitude in the late 1950s to 1970s that antacids should be taken only on demand was unjustified and erroneous. 13 recent endoscopic controlled studies have confirmed the efficacy of antacids in the healing of duodenal ulcer, achieving about 75% healing in 4 weeks. The efficacy of antacids in promoting gastric ulcer healing has been less well studied and the results are controversial. The most appropriate and economical antacid regimens for the treatment of duodenal ulcer disease should include tablets or liquid that have acid neutralising capacity of 400 mmol/day given at least an hour after meals. As a long term therapy, antacids appear to work, but need be taken in multiple daily doses, a regimen which is unlikely to meet with long term patient compliance. Patients with gastro-oesophageal reflux disorders or pregnancy-related reflux have also benefited from the usage of antacids ad libitum. Early previous studies have clearly demonstrated the efficacy of antacids in reducing gastro-oesophageal reflux and healing of reflux oesophagitis. The acidity of the gastric contents is the major determining factor in the outcome of the aspiration pneumonitis occurring during delivery. The prophylactic use of antacids during delivery has helped to reduce the severity of this complication. Similarly, the prophylactic administration of antacid aiming to maintain gastric pH between 3.5 to 7.0 has resulted in significant reduction of bleeding due to stress associated ulcers and/or erosive haemorrhagic gastritis in critically ill patients. Antacid therapy, however, is controversial in the management of nonulcer dyspepsia or nonsteroidal anti-inflammatory drug related upper gastrointestinal mucosal damage. Undoubtedly, antacids have major roles to play in the treatment of gastric acid related disorders. They have clear advantages and disadvantages when compared with the antisecretory agents. New proton pump inhibitors in particular have certainly superseded antacids and even the H2-receptor antagonists in many respects. However, the long term safety record of antacids remains unsurpassed by any of the new antisecretory agents.

Abstract
Gastro-oesophageal reflux disease is a common condition with a complex pathophysiology. Despite the spectrum of abnormalities, gastric acid has a central role in mucosal damage, and the mainstay of medical treatment is suppression of gastric acid secretion. The results of antisecretory treatment as assessed by endoscopic healing are reviewed. H2 receptor antagonists give more rapid symptom relief than placebo and can produce endoscopic improvement in 31-88% of cases depending on the severity of oesophagitis. Complete healing, however, is seen only in 27-45% of patients and these have mainly grades I-II disease. Improved healing rates can be obtained by increasing the degree of acid suppression or the length of treatment. The addition of a prokinetic agent may be beneficial. Omeprazole heals 67-92% of patients overall and although most successful in the lower grades of oesophagitis, can also heal 48-62% of patients with grade IV disease. The degree and rate of healing seem to be related to the reduction in oesophageal acid exposure and thus may correlate with the degree and duration of acid suppression over 24 hours obtained by the various treatments. The underlying pathophysiology is unchanged, however, and long term treatment may be needed to maintain remission.

Abstract
The basis of treatment of reflux oesophagitis is change in behaviour and lifestyle. In the presence of mild symptoms antacids/alginate may be instituted. In case of Savary grade I and II oesophagitis at endoscopy, H2-receptor antagonists (H2RAs), alone or in combination with a prokinetic or mucosaprotective agent, are the first choice of treatment. Drug treatment should be continued for at least 8-12 weeks. In case of resistance to treatment or in case of severe and/or complicated reflux oesophagitis, omeprazole should be prescribed. Maintenance treatment is necessary in patients with severe reflux oesophagitis and in patients with quick relapses, once therapy has stopped. Full-dose H2RAs are required to prevent recurrences. In case of resistance to H2RAs, omeprazole should be used. Anti-reflux surgery should be considered in patients, especially at young age, who have an insufficient response to medical management, due either to lack of compliance or to therapeutic failure.

Abstract
As in duodenal and gastric ulcer patients, a highly significant correlation between suppression of 24-h intragastric acidity and healing rates in reflux oesophagitis patients was demonstrated by meta-analysis of data obtained from the literature (r = 0.90; p less than 0.001). Furthermore, we have demonstrated in eight patients with reflux oesophagitis that 2-week treatment courses with 300 mg ranitidine twice daily and 300 mg four times daily progressively decreased 24-h intraoesophageal acidity but only moderately elevated basal and meal-stimulated serum gastrin concentrations, significantly below gastrin values obtained after a 2-week treatment course with 20mg omeprazole once daily. Further studies are awaited to demonstrate long-term effects on both healing rates and serum gastrin responses with high doses of histamine H2-receptor antagonists.

Abstract
Ranitidine, a histamine H2-receptor antagonist, is now well established as a potent inhibitor of gastric acid secretion effective in the treatment and prophylaxis of gastrointestinal lesions aggravated by gastric acid secretion. Therapeutic trials involving several thousands of patients with peptic ulcer disease confirm that ranitidine 300mg daily administered orally in single or divided doses is at least as effective as cimetidine 800 to 1000mg daily in increasing the rate of healing of duodenal and gastric ulcers. Similar dosages of ranitidine have been shown to relieve the symptoms of reflux oesophagitis and heal or prevent gastrointestinal damage caused by ulcerogenic drugs. Ranitidine 150mg orally at night maintains ulcer healing in the long term. Ranitidine has also demonstrated good results in the treatment of Zollinger-Ellison syndrome and in the prevention of aspiration pneumonitis when given prior to surgery and to pregnant women at full term. It may also have a place in the management of acute upper gastrointestinal bleeding and in the prevention of stress ulcers in the intensive care setting, although these areas require further investigation. Ranitidine has been used safely in obstetric patients during labour, in children, the elderly, and in patients with renal impairment when given in appropriate dosages. The drug is very well tolerated and is only infrequently associated with serious adverse reactions or clinically significant drug interactions. Even at high dosages, ranitidine appears devoid of antiandrogenic effects. Ranitidine is clearly comparable or superior to most other antiulcer agents in the treatment and prevention of a variety of gastrointestinal disorders associated with gastric acid secretion. With its favourable efficacy and tolerability profiles, ranitidine must be considered a first-line agent when suppression of gastric acid secretion is indicated.

Abstract
The symptomatic effect of a 2-week low-dose antacid tablet regimen was assessed in a prospective, double-blind, randomized, placebo-controlled, crossover trial in 47 patients with endoscopically verified reflux oesophagitis. During treatment with antacid there were lower global symptomatic scores (p less than 0.05), less acid regurgitation (p less than 0.05), and fewer days (p less than 0.01) and nights (p less than 0.05) with heartburn than during placebo therapy. Also, significantly more patients preferred antacid than placebo treatment (p less than 0.05). Thus, a low-dose antacid tablet regimen relieves symptoms significantly better than placebo in patients with reflux oesophagitis.

Abstract
Besides changes in behaviour and lifestyle we nowadays have the choice of specific drugs in the treatment of reflux oesophagitis. A distinction can be made in motility modulating drugs, which stimulate oesophageal peristalsis and LOS pressure, mucosa-protecting drugs, which form a protective layer on the oesophageal mucosa, acid neutralizing (antacids) and acid suppressing drugs (H2-receptor antagonists, omeprazole). So far the results of medical therapy of reflux oesophagitis are still suboptimal. Giving the H2-receptor antagonists with the evening meal would possibly be more appropriate. A valid alternative is the mucosa-protecting agent sucralfate. Monotherapy will probably be insufficient for full healing, which explains why trials of combination therapy (H2-receptor antagonists plus sucralfate or plus cisapride) are being conducted. If omeprazole becomes available, it will revolutionize the therapy of severe reflux oesophagitis. Many questions (dose, duration, maintenance, safety monitoring etc.) remain to be determined.

Abstract
Twenty-eight patients with endoscopically confirmed erosive or ulcerative esophagitis completed an 8-week placebo-controlled trial evaluating the symptomatic and endoscopic improvement obtained with ranitidine, 150 mg twice daily. Twice daily the patients recorded the number of episodes of retrosternal pain, regurgitation, and pyrosis on a diary card during a trial period of 1 week and during the 1st and 5th study week. Video documentation of endoscopy findings was undertaken before and at the end of the trial. The symptomatic relief obtained with ranitidine was significantly better than that obtained with placebo. The videotapes were assessed blindly and independently by three experienced fiberoptic endoscopists. The tapes were also recoded and reassessed by the same endoscopist. No systematic difference between different observers, either before or after treatment, could be detected. The interobserver variation, expressed as Kendall's tau b correlation coefficient, was 0.44 to 0.74. This coefficient was higher in intra-observer variation (0.63 to 0.91). Corresponding kappa-values for inter- and intra-observer variations were 0.12 to 0.30 and 0.27 to 0.85, respectively. The esophagitis, as judged by all observers, improved more in the ranitidine group than in the placebo group, but the difference did not reach statistical significance.

Abstract
Twenty-nine patients were treated with a carbenoxolone/antacid/alginate preparation (Pyrogastrone) and 30 with antacid/alginate alone four times each day for 8 weeks, in a double-blind study, to ascertain the value of carbenoxolone in the treatment of patients with endoscopically confirmed reflux oesophagitis. Symptom review every 2 weeks and endoscopic findings every 4 weeks were converted to a 6-point grading system to facilitate statistical comparison, using a stochastic model for predicting the rate of change in grades during treatment. Carbenoxolone-treated patients showed an 82% improvement in symptom grades over 8 weeks and improved 50% faster (P less than 0.01) than did control patients, who showed a 63% improvement. Endoscopic improvement was not significantly different in the first 4 weeks, although healing was better maintained in carbenoxolone-treated patients during the second 4 weeks (P less than 0.05). At the low doses used (5 X 20 mg daily) no significant side effects of carbenoxolone were encountered. Pyrogastrone should be considered as a therapeutic alternative in patients who fail to respond to routine management with antacids.
