Rebamipide in gastric mucosal protection and healing: An Asian perspective

This review emphasizes the exemplary safety and efficacy of rebamipide in the treatment of gastric ulcers and other mucosa-related disorders, positioning it as a viable candidate for inclusion in treatment guidelines across India and globally. An in-depth literature review of rebamipide was carried out on PubMed and Google Scholar. Rebamipide has a multifaceted mechanism of action, including prostaglandin synthesis, scavenging free radicals, and enhancing mucin production, leading to enhanced mucosal protection and ulcer healing. Rebamipide serves as a highly effective and safe treatment option for gastric ulcers and gastroesophageal reflux disease. The efficacy of this drug in treating ulcers often surpasses that of routinely used agents such as pantoprazole, sucralfate, misoprostol, famotidine, lansoprazole, and esomeprazole. This superiority of rebamipide can be attributed to the low rate of adverse events associated with it and its mild side effects, contributing to its widespread adoption across Southeast Asia and Russia. This popularity extends to its application beyond gastrointestinal ailments. Notably, it has been successfully employed in the treatment of ophthalmological, oncological, and bone regeneration-related issues. Rebamipide's exemplary safety and efficacy in treating gastric ulcers and other mucosa-related disorders support its potential for inclusion in treatment guidelines, not only in India but also globally.

The value of increased intestinal permeability in the pathogenesis of internal diseases

In the process of evolution in the gastrointestinal tract, a system of protection against bacterial and food antigens from getting into the blood was formed. The causes of increased intestinal permeability (IIP) can be microbiota imbalance, use of antibiotics, non-steroidal anti-inflammatory drugs, stress, diet rich in fructose, glucose, sucrose and long-chain fatty acids. The appearance of IIP may be of paramount importance in the pathogenesis of autoimmune diseases. A diet low in fermentable oligodimonosaccharides and polyols, pre- and probiotics, polyphenols, vitamins, short-chain fatty acids, dietary fiber, glutamine contributes to the reduction of IIP. It has been established that the cytoprotector rebamipide strengthens the barrier function throughout the gastrointestinal tract, which is reflected in practical recommendations for its use in diseases accompanied by IIP. The study of this direction will contribute to the emergence of a new strategy for the treatment of internal diseases.

The effect of the FODMAP and rebamipid diet on the activity of disaccharidases in patients with enteropathy with impaired membrane digestion

Aim. To compare the effect of a diet low in fermentable oligo-, di-, monosaccharides and polyols (fermentable oligosaccharides, disaccharides, monosaccharides and polyols FODMAP) and rebamipide on carbohydrate tolerance and disaccharidases activity in patients with maldigestive enteropathy (ENMP). Materials and methods. The study included 61 patients with ENMP with reduced small intestine carbohydrases. Their glucoamylase activity was 100 ng glucose/mg tissue min (quartile 53, 72), maltase 504 (quartile 258, 708), sucrase 43 (quartile 25, 58), lactase 8 (quartile 4, 20). Group 1 included 19 people on a low FODMAP diet. The 2nd group included 42 patients who were on a normal diet and received rebamipide 300 mg/day. Patients were monitored weekly for 8 weeks. Results. In 16 patients of the 1st group, abdominal pain and stool disorders decreased, in 15 patients, swelling and rumbling in the abdomen stopped. Glucoamylase activity increased to 196 (quartile 133, 446, р0.024) ng glucose/mg tissue min, maltase activity increased to 889 (quartile 554, 1555, p0.145), sucrase activity increased to 67 (quartile 43, 175, p0.039), lactase activity increased to 13 (quartile 9, 21, p0.02). After the diet was discontinued, intestinal symptoms in patients of group 1 resumed. In 27 patients of the 2nd group after 4 weeks dyspeptic manifestations decreased, in 34 patients the tolerability of products containing FODMAP improved. Continuation of treatment up to 8 weeks contributed to a further improvement in well-being. Glucoamylase activity increased after 4 and 8 weeks to 189 (quartile 107, 357, p0.013) and 203 (quartile 160, 536, p0.005), respectively; maltase up to 812 (quartile 487, 915, p0.005) and 966 (quartile 621, 2195, р0.0012); sucrases up to 60 (quartile 34, 105, p0.013) and 75 (quartile 52, 245, р=0.003); lactase up to 12 (quartile 8, 12, p0.132) and 15 ng glucose/mg tissue min (quartile 10, 20, р0.092). Conclusion. The clinical symptoms of fermentable carbohydrate intolerance and increased membrane enzyme activity are reduced by a low FODMAP diet in patients with ENMT, but clinical symptoms of food intolerance reappear when switching to a normal diet. Treatment with rebamipide improves food tolerance and consistently increases the activity of TSOTS enzymes after 4 and 8 weeks.

Effectiveness of Rebamipide as a part of the <i>Helicobacter pylori</i> eradication therapy in Russia: a meta-analysis of controlled trials

Aim. To perform a meta-analysis of the data on Rebamipide efficacy and safety as a part of Helicobacter pylori eradication therapy in Russian patients. Materials and methods. A search for original studies was conducted in the electronic database of the Russian Science Citation Index (RSCI) on the Scientific Electronic Library (SEL Elibrary.ru). Google (Google.com) was used for the "grey" search. All Russian controlled studies comparing the efficacy and/or safety of Rebamipide as a part of the regimen of H. pylori eradication therapy were included in the final analysis. Results. In 6 included controlled trials with a cumulative population (considering double comparisons between multiple groups) of 531 patients (273 in Rebamipide groups and 258 in groups without Rebamipide), the pooled eradication effectiveness was 90.376% (95% confidence interval CI 86.31193.560) in patients receiving Rebamipide and 81.681% (95% CI 76.49986.141) in patients receiving eradication regimens without Rebamipide. The meta-analysis showed that the Rebamipide addition to eradication regimens significantly improved efficacy (odds ratio 2.162, 95% CI 1.2683.685; p=0.005). No significant heterogeneity was found between study results (p=0.863; I2=0.00%); therefore, a fixed effects model was used in the resulting analysis. In addition, the meta-analysis of included studies showed a reduction of adverse events (odds ratio 0.569, 95% CI 0.3330.970) in the groups receiving Rebamipide; p=0.038). This effect of Rebamipide deserves special attention and requires additional study, as the result was at the border of statistical significance in the subanalysis of three studies with a large margin of risk reduction in one of them (with the largest sample of patients). Conclusion. The present meta-analysis demonstrated that the Rebamipide addition to H. pylori eradication regimens significantly improves the treatment effectiveness in the Russian patient population.

[Enteropathy with impaired membrane digestion and the prospects for cytoprotective therapy]

The article describes enteropathy with impaired membrane digestion (EIMD) as a new nosological form. The main clinical manifestation of EIMD is the poor tolerance of food products, in particular carbohydrates and a decrease in the activity of membrane enzymes, in particular, carbohydrates, in the mucous membrane of the small intestine. The cause of the disease can be acute intestinal infections, viruses, drugs and other agents that damage the small intestine. The pathophysiology, clinical picture and diagnosis of EIMD are described. The basis of therapy is rebamipide, which has the ability to reduce the symptoms of carbohydrate intolerance and increase the activity of disaccharidases.

[Rebamipide: evidence base for use in gastroenterology]

Rebamipide is a cytoprotective drug that has been used in practical gastroenterology for 30 years. This article summarizes the main results of the most relevant clinical studies of rebamipide in diseases of various parts of the gastrointestinal tract, including the esophagus, stomach, small and large intestine.

[NSAID enteropathy]

Nonsteroidal anti-inflammatory drugs (NSAIDs) are one of the most commonly used drugs in the world, and their side effects are very high. First of all, these are NSAID gastropathy, but in the long term, 5070% of NSAIDs cause damage to the small intestine (NSAID enteropathy), sometimes with serious consequences. To date, no drugs have been proposed with proven effectiveness to prevent this side effect. Apparently, this is not due to the fully clarified mechanism of pathogenesis. The most promising is the hypothesis of the participation of individual representatives of microflora in the development of enteropathy. Therefore, modulating the intestinal flora with the help of probiotics can be the basic therapeutic strategy for the prevention and treatment of such damage.
