ABSTRACT Peptic ulcers, mainly located in the stomach and duodenum, affect 5-10% of the population, with risk factors such as Helicobacter pylori and the use of non-steroidal anti- inflammatory drugs (NSAIDs). In Peru, they are a significant cause of digestive mortality. Supplementation with Vitamin E and the probiotics Lactobacillus reuteri DSM 17938 show protective potential against ulcers by reducing oxidative stress and improving the gastric mucosa, so they can mitigate the adverse effects of NSAIDs and promote healing of the mucosa, being a promising preventive strategy. Objective: Demonstrate the antiulcerogenic effect of pretreatment with Vitamin E and Lactobacillus reuteri DSM 17938 in Mus musculus var. albinus. Method: Thirty specimens of Mus musculus var. albinus distributed in six groups received pretreatment for seven days with Vitamin E 400 mg/kg/day (GV), Lactobacillus reuteri DSM 17938 109 CFU/Kg B.C. (GP) and both supplements (GPV). Another group received Omeprazole 20 mg/kg/day (GO). On the eighth, ninth and tenth day, gastric ulcer was induced with Naproxen Sodium 80 mg/Kg b.w., along with the group that only received this medication (GN), except the white group (GB) that did not receive any treatment. The tissue samples were then evaluated microscopically to determine the effects of the treatments. Results: The histopathological findings showed that the GB group presented mild inflammatory infiltrate, while the GN group presented hemorrhage, edema, erosion and ulceration. The GO group presented moderate loss of epithelium without ulceration. The GV, GP and GPV groups did not present gastric ulcer, hemorrhage or mild leukocyte infiltration; GP presented moderate erosion of the gastric mucosa, GV and GPV presented mild erosion. Furthermore, the GV group presented a slight loss of epithelial cells. These results are consistent with an antiulcerogenic response of the pretreatment against gastric injury induced by Naproxen Sodium in mice. Conclusion: The antiulcerogenic effect of pretreatment with Vitamin E and Lactobacillus reuteri DSM 17938 was demonstrated in Mus musculus var. albinus
