Pharmacologic management of peptic ulcer disease continues to evolve with the introduction of diverse types of new therapeutic agents. The ideal aims of treatment of peptic ulcer disease are to relieve pain, heal the ulcer, and delay ulcer recurrence. This article provides a broad perspective on the pharmacology and therapeutic actions of antiulcer drugs. To date, no drug meets all goals of therapy. Drug treatment of peptic ulcers is targeted at either counteracting aggressive factors or stimulating the mucosal defense. Drugs that inhibit or neutralize gastric acid secretion include histamine H2-receptor antagonists, proton pump inhibitors, anticholinergics, prostaglandins, and antacids. H2-receptor antagonists have become first-line drugs for treatment of uncomplicated duodenal ulcers, gastric ulcers, prevention of ulcer relapse, and mild esophagitis. However, H2-receptor antagonists, like other gastric antisecretory/antiulcer drugs, have high rates of ulcer recurrence following discontinuation of therapy. They therefore need to be administered continuously in patients prone to such recurrences. Omeprazole has emerged as a major drug for the treatment of severe erosive esophagitis, refractory ulcers, and Zollinger-Ellison syndrome. The major disadvantage of proton pump inhibitors is the concern for their long-term safety. The roles of M1-antimuscarinic agents and antacids have not been fully defined. Misoprostol, effective for the treatment of gastric and duodenal ulcers, is now the only drug that prevents ulcers induced by nonsteroidal anti-inflammatory drugs. Mucosal protective drugs that do not inhibit gastric acid secretion include sucralfate and organic bismuth salts. Sucralfate is a nonsystemic, well-tolerated, effective drug for treatment of duodenal ulcers and prevention of duodenal ulcer relapse. The organic bismuth salt bismuth subcitrate is efficacious in the treatment of duodenal and gastric ulcers. Furthermore, it has also been established that it alters the course of ulcer recurrence. However, bismuth encephalopathy is a major toxicity concern that needs to be addressed.(ABSTRACT TRUNCATED AT 250 WORDS)

Sucralfate (Sc) suspension 6 g/day and ranitidine (Rn) tablets, 150 mg, were compared in 125 patients in a double-blind, multicenter, endoscopically controlled trial in the treatment of reflux esophagitis. Inclusion criteria were symptomatic reflux (number and severity of attacks) and endoscopic evidence of esophagitis (grades 1 to 4). Clinical assessments were performed on entry, and at 4 and at 8 weeks, and endoscopy was repeated at 8 weeks. Sc suspension and Rn placebo or Sc placebo and Rn tablets were taken on waking and immediately before retiring at night. Of the 125 patients, 27 were withdrawn because of default (Rn = 4; Sc = 14), noncompliance (Rn = 1; Sc = 2), or the development of congestive cardiac failure (Rn = 1), diarrhea (Rn = 1; Sc = 1), nausea (Sc = 1), constipation (Sc = 1), and hematemesis (Sc = 1). Analysis was performed on the remaining 98 patients, 43 of whom had been treated with Sc and 55 with Rn. Heartburn, acid regurgitation, epigastric pain, dysphagia, and chest pain were relieved in 34% vs 40%, 67% vs 72%, 71% vs 57%, and 86% vs 63% for Sc and Rn, respectively. There was no significant difference between the two groups. Endoscopic healing occurred in 47% of the Sc- and in 31% of the Rn-treated patients (chi 2 = 2.50), and healing or improvement was noted in 81% of the Sc- and 64% of the Rn-treated patients. This difference approached statistical significance (chi 2 = 3.73). There was no obvious endoscopic benefit in 8 of the 43 and 20 of the 55 patients in the groups treated with Sc and Rn, respectively. Although the findings with sucralfate and ranitidine in patients with reflux esophagitis completing the trial suggest a benefit of these agents, the absence of a placebo control group and the high default rates, particularly for those receiving sucralfate, preclude any firm conclusions as to relative or specific efficacy of these agents in this condition.

In previous studies it has been reported that, after being labeled with technetium, sucralfate, an useful drug in peptic diseases, can be used to detect peptic lesions of the digestive tract. In this work we report our experience with this technique in the diagnosis of esophagitis. 25 studies (11 controls and 14 patients) were undertaken. Sucralfate scintigraphy was normal in the 11 control studies, and abnormal in 10 out of 14 patients. Scintigraphy was abnormal in peptic as well as caustic lesions.

Sixty patients with endoscopically verified oesophagitis entered a double-blind clinical study comparing 1 g sucralfate granulate given four times daily and 400 mg cimetidine twice daily. The efficacy, as judged by endoscopy and the symptomatic response, were studied after 4, 8, and 12 weeks of treatment. Macroscopic healing of oesophagitis was defined as complete epithelialization of all oesophageal erosive lesions classified in accordance with Savary-Miller. Groups were comparable with regard to demographic data. The healing rate at 12 weeks' end point was 62% in the sucralfate group and 59% in the cimetidine group (NS). Half of the patients in both groups (NS) were relieved of symptoms. No adverse effects were recorded. Sucralfate and cimetidine appear to be equally efficient in the treatment of reflux oesophagitis.

Sucralfate is a nonsystemic agent that is effective in protecting the gastroduodenal mucosa against injury. In addition, sucralfate is effective in the healing of acute duodenal and gastric ulceration, the therapy of esophagitis, and the prevention of ulcer recurrence. The mechanisms responsible for sucralfate's successful protective and therapeutic actions include the adsorption of pepsin and bile acids, the stimulation of bicarbonate and mucus secretion, and stimulation of endogenous synthesis of prostaglandins. When sucralfate is given to experimental animals or humans, it stimulates endogenous synthesis and release of prostaglandin E2 and inhibits thromboxane release. Pretreatment of animals with the cyclooxygenase inhibitor indomethacin results in a marked decrease in the protective effect of sucralfate against alcohol injury. Sucralfate also increases epidermal growth factor binding to ulcerated areas and stimulates macrophage activity. In addition, sucralfate stimulates endogenous sulfhydryl compounds. At the microscopic level sucralfate protects the vascular integrity of the mucosa and the mucosal proliferative zone. It also stimulates epithelial cell restitution and stimulates cell proliferation. The administration of sucralfate before acute injury results in decreased depth and extent of injury and in acceleration of healing. Because of sucralfate's ability to stimulate the protective and reparative mechanisms of the gastric and duodenal mucosa, it is an important nonsystemic agent for the therapy and prevention of peptic ulceration.

A total of 36 patients with grade 2 or greater erosive esophagitis and an abnormal 24-h pH monitor study, were treated in a randomized, double-blind fashion to assess the efficacy of sucralfate suspension as adjunctive therapy to cimetidine for severe esophagitis secondary to gastroesophageal reflux. Treatment consisted of cimetidine, 300 mg qid and either sucralfate suspension (1 g/10 ml) or an identical placebo suspension, 10 ml after meals and 20 ml hs. Patients were treated for 12 wk unless endoscopic healing occurred earlier. Initial evaluation and monthly follow-up consisted of symptom monitoring, endoscopic evaluation and pre- and post-therapy esophageal manometry, Bernstein test, and 24-h pH monitoring. The combination of cimetidine and sucralfate suspension was superior to cimetidine alone in improving daytime heartburn symptoms (p less than 0.05) but not nighttime heartburn, dysphagia, or regurgitation. Sucralfate plus cimetidine improved the overall endoscopic outcome of esophagitis more than cimetidine alone (p less than 0.05). More patients exhibited endoscopic healing in the adjunctive sucralfate group than in the cimetidine-only group. Endoscopic healing, however, was not statistically different between groups. We conclude that sucralfate used as adjunctive therapy to cimetidine resulted in improvement of some of the symptoms of reflux, and probably increases the likelihood of complete healing of esophagitis, compared with cimetidine alone.

Peptic esophagitis is a common complication of gastroesophageal reflux. Therapeutic measures aimed at reinforcing the anti-gastroesophageal reflux barrier, reducing acid secretion, or increasing the defense mechanisms of the esophageal mucosa are used to treat this form of esophagitis. The purpose of this study was to determine the efficacy of sucralfate in the treatment of peptic esophagitis in children. We studied 75 patients diagnosed endoscopically as suffering from esophagitis. The age of the patients ranged from three months to 13 years. Gastroesophageal reflux was diagnosed by isotopic investigation and/or radiologically. None of the patients had kidney disease or had received anti-inflammatory drugs, sucralfate, or cimetidine during the preceding two weeks. The patients were divided into three groups of 25. Patients were homogeneous in age, sex, nutritional status, symptoms, and grade of esophagitis. All patients in each group were treated with cimetidine, sucralfate tablets, or sucralfate suspension. No other dietary or postural measures were prescribed. Clinical examinations were carried out on Days 14, 28, 42, and 56, with an endoscopic examination on Day 28. Endoscopy was repeated on Day 56 if the course was unsatisfactory. Statistical examination of the data showed that there were no differences between the three groups. Sucralfate is a useful drug for the treatment of peptic esophagitis in children.

The aim of this study was to analyze the results and the quality of methodology of 51 controlled double blind trials in the medical treatment of gastroesophageal reflux. The results of H2 receptor antagonist treatment were evaluated by the pooling method. Evaluation of methodology was carried out by using a special form filled in by two independent observers. The major criticisms in methodology were: small sample size, unblind evaluation of end-points, inappropriate statistical tests for small samples, and inaccurate handling of the withdrawals. There were only two trials concerning antacids versus placebo: one showed that Novaluzid improved symptoms and another that Maalox did not differ from placebo. The effectiveness of alginic acid and domperidone on either symptoms or endoscopic lesions was not demonstrated. Metoclopramide and bethanechol produced significant relief of reflux symptoms. Sucralfate and bethanechol were better than placebo in improvement of esophagitis endoscopic lesions. The H2-inhibitors efficiently relieved symptoms and esophagitis. Pooling analysis showed that H2-inhibitors were superior to placebo in the healing of esophagitis; the odds ratios were 2.5 for cimetidine and 3.3 for ranitidine, without significant difference. Omeprazole was better than ranitidine in relief of symptoms and esophagitis. The comparison of cimetidine alone with cimetidine plus metoclopramide showed that combined therapy was better in one trial out of two. New controlled trials are necessary to compare these different drugs and their association.

Sucralfate has been evaluated in reflux esophagitis. The rationale for its effectiveness is based on its protective adherence to denuded mucosal surfaces and its bile salt binding properties. According to Weiss et al (5), healing occurred in 72% and improvement in 14% of sucralfate treated patients, compared respectively to 40% and 20% receiving placebo (p less than 0.05). According to Laitinen et al (6) esophagitis healed in 53% of patients receiving sucralfate, against 34% of an alginate/antacid-treated group. Symptoms disappeared, or improved in almost 70% of both groups. Hameeteman et al (7) found improvement of esophagitis in 53% and healing in 31% after sucralfate, compared with 67% and 14% respectively after cimetidine. Symptomatic improvement was good and comparable in both groups. Simon et al (8) found endoscopic healing in 64% and improvement in 27% of sucralfate-healed patients, compared with 68% and 21% respectively after ranitidine. Symptom relief and antacid consumption was comparable in both groups. Sucralfate appears to be a safe and efficacious locally active mucosal protecting agent for the treatment of reflux esophagitis. Its efficacy is comparable to that of H2-receptor blockers.

Sucralfate is a recently introduced drug that has received acceptance as a nonsystemic, locally active antiulcer agent used in the treatment of duodenal ulcer disease. In addition, sucralfate has been used for the treatment of gastric ulcer and a variety of other gastrointestinal diseases. However, the use of sucralfate to treat caustic esophagitis has not been clinically investigated, and a review of the literature yielded scant information (1). Herein, we report our experience with sucralfate in the treatment of a case of lye-induced esophagitis.
