Comparative Study Between the Efficacy of Rebamipide, Sucralfate AL-AZHAR ASSIUT MEDICAL JOURNAL VOL 13 , NO 1 , JANUREY 2015 SUPPL COMPARATIVE STUDY BETWEEN THE EFFICACY OF REBAMIPIDE, SUCRALFATE AND PANTOPRAZOLE IN TREATMENT OF POST BANDING VARICEAL ULCERS Gamal Mohammad Mohammad Soliman1,Yasser Amer2 and Sadek Mostafa3 Departments of Tropical Medicine1, General Surgery2 and Internal Medicine3 faculty of Medicine - Al- Azhar University ـــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ ــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ ABSTRACT Background: Endoscopic variceal band ligation (EVL) is an effective procedure to control and prevent variceal bleeding in patients with liver cirrhosis. Although EVL has some complications, yet these complications are related to post-EVL ulcers. Few data exist regarding therapy of post-ligation ulcer and treatment been mostly empirical with drugs used for peptic ulcer diseases. Aim of the work: is to compare between the efficacy of rebamipide, sucralfate and pantoprazole in treatment of post banding variceal ulcers. Methods: seventy five patients with oesophageal varices eligible for elective band ligation represented the population of the study. The patients were allocated into three groups; rebamipide group, they received rebamipide 100 mg 3 times daily; pantoprazole group, they received pantoprazole 40 mg/day orally at morning; sucralfate group, they received sucralfate 1gm every 6 hours, for 14 days beginning at the next day of band ligation. Subjects underwent EGD 14 days after banding. Primary outcomes included the size and number of ulcers and the subjects' reports of bleeding, dysphagia, chest pain and vomiting. Results: At follow-up endoscopy, the number of patients with post-band ulcers and size of ulcers were similar in the three groups. However, the number of ulcers for each patient is statistically significant less in rebamipide group when compared to pantoprazole and sucralfate (P < .001). Chest pain, dysphagia and vomiting scores were not significantly different. Dysphagia was by far the most common symptom with no case of bleeding was reported in all patients of the studied groups. Conclusion: Rebamipide is effective in decreasing the post banding complication and reducing size of ulcer as well as the number of ulcers with no significant effect on post banding ulcer formation. Rebamipide can be used routinely in settings of post-EVL as a good alternative to pantoprazole and sucralfate.

Rebamipide is one of the gastroprotective drugs EVL is associated with complications such as able to intervene effectively in the process of hemorrhage, chest pain, dysphagia, and ulcer healing and effectively improve the odynophagia due to post-EVL ulcers in the quality of ulcer healing (8).Clinical and esophageal mucosa (3). experimental data demonstrate that rebamipide The rubber band causes hemostasis, accelerates gastric ulcer healing, prevents ulcer thrombosis and sloughing of variceal column; it relapse, and protects gastric mucosa against slough off in the following 24-72 hours, leaving acute injury caused by various noxious agents a shallow ulcer behind(4)that heals within 2–3 (9).

Pharmaceutical Form Carafate is a white, uncoated capsule-shaped tablet. One side is plain, the other embossed with the word ‘CARAFATE’. Dimensions: 20 mm x 9 mm x 7mm 4. Clinical Particulars 4.1 Therapeutic indications Treatment of acute, non-malignant gastric ulcer and duodenal ulcer. Maintenance therapy to prevent the recurrence of duodenal ulcers. 4.2 Dose and method of administration Acute ulcerous conditions The recommended adult dose of Carafate for duodenal ulcer and gastric ulcer is 1 g tablet three times a day, one hour before meals and one 1 g tablet at bedtime or two 1 g tablets twice daily taken before breakfast and at bedtime (for up to 8 weeks). For relief of pain, antacids may be added to the treatment. However, they should not be taken within two hours before or after sucralfate intake. In duodenal ulcer, while healing with sucralfate often occurs within two to four weeks, treatment should be continued for up to 8 weeks unless healing has been demonstrated by x-ray and/or endoscopic examination. In the case of gastric ulcers an alternative treatment should be considered if no objective improvement is observed following 6 weeks of sucralfate therapy. Large gastric ulcers that show a progressive healing tendency may require the full 8 weeks of therapy. Maintenance treatment To reduce the risk of recurrence of duodenal ulcers, the recommended dose is one 1 g tablet before breakfast and one at bedtime (for up to 12 months).

Proton pump inhibitors cause few adverse effects with short-term use; however, long-term use has been scrutinized for appropri- ateness, drug-drug interactions, and the potential for adverse effects (e.g., hip fractures, cardiac events, iron deficiency, Clostridium difficile infection, pneumonia). Adults 65 years and older are more vulnerable to these adverse effects because of the higher prevalence of chronic diseases in this population.

Email: [email protected]. Background: A postprandial proximal gastric acid pocket (PPGAP) that escapes neutralization by food was demonstrated in volunteers and gastroesophageal reflux disease (GERD) patients. It is elusive; however, if this acid layer is morphologically best conceptualized as a real pocket or a film. This study aims to analyze the effect of oral sucralfate administration on PPGAP to shed some light on PPGAP morphology and treatment. Methods: Twenty-six patients (mean age 51 years, 19 females) were studied. A pull-through pH monitoring was performed from 5 cm below the lower border of the lower esophageal sphincter (LES) to the actual border in increments of 1 cm, in a fasting state, 10 min after a fatty meal and 10 min after oral sucralfate administration. PPGAP was defined by an acid reading (pH <4) in the proximal stomach between non-acid segments distally (food) and proximally (proximal pH transition point).

  • REVISÃO / REVIEW but It Is Interesting to Review Some Aspects of the GERD Refractory Patients to the Proton Pump Inhibitors Treatment
    ARQGA/1633 REFRACTORY GASTROESOPHAGEAL REFLUX DISEASE Joaquim Prado P. MORAES-FILHO* ABSTRACT - Context - Gastroesophageal reflux disease (GERD) is a condition which develops when the reflux of stomach contents causes troublesome symptoms and/or complications. Its pathophysiology, diagnosis and treatment have frequently been analyzed REVISÃO / REVIEW but it is interesting to review some aspects of the GERD refractory patients to the proton pump inhibitors treatment. The treatment encompasses behavioral measures and pharmacological therapy. The majority of the patients respond well to proton pump inhibi- tors treatment but 20%-42% of them may not do so well. Patients who are unresponsible to 4-8 weeks’ treatment with proton pump inhibitors (omeprazole, pantoprazole, rabeprazole, lansoprazole, esomeprazole, pantoprazole-Mg) might have so-called refractory GERD. Results - In some cases the patients are not real refractory because either they do not have GERD or the disease was not correctly treated, but the term refractory is still employed. Although debatable, the Brazilian GERD Consensus based upon evidences recommends as first step in the diagnosis, the upper digestive endoscopy to exclude the diagnosis of peptic ulcer and cancer and in some cases identify the presence of esophageal mucosa erosions. Conclusions - The main causes of the so-called refractory GERD are: (1) functional heartburn; (2) low levels of adherence to proton pump inhibitors treatment; (3) inadequate proton pump inhibitors dosage; (4) wrong diagnosis; (5) co-morbidities and pill-induced esophagitis; (6) genotypic differences; (7) nonacid gastroesophageal reflux; (8) autoimmune skin diseases; (9) eosinophilic esophagitis. HEADINGS – Gastroesophageal reflux, drug therapy. Proton pump inhibitors. INTRODUCTION failure may occur. In fact, unfortunately 20% to 42% of the cases may not respond to PPI therapy, with Gastroesophageal reflux disease (GERD) is a persistence of reflux symptoms or even the occurrence condition that develops when the reflux of stomach of new symptoms and esophagitis(2).
