Patients will be randomized to one of three treatment groups in a 1:1:1 ratio. * Group Rebamipide, receiving standard therapy and rebamipide 300 mg per day * Group Pantoprazole , receiving standard therapy and pantoprazole 40 mg per day * Group Combination of Rebamipide and Pantoprazole, receiving standard therapy, rebamipide 300 mg per day and pantoprazole 40 mg per day Standard therapy in the study refers to the use of DOAC in accordance with applicable clinical guidelines. Physical examination, blood pressure/heart rate measurement, Adverse Events (AEs) control, concomitant medications and compliance assessment will be performed every visit. An Esophagogastroduodenoscopy (EGD) with H. pylori detection, Lanza score assessment, GOS questionnaire, and laboratory tests (blood and stool tests) will be performed on screening and visit 4.
