Inclusion Criteria: * Patients with acute ischemic stroke aged ≥18 years old who, regardless of etiology and mechanism, do not have a definitive indication for anticoagulation, and whose symptoms onset has been within the last 14 days; * Receiving standard therapy for acute management of ischemic stroke; * For patients treated with fibrinolytics, a minimum period of 24 hours after the infusion of the lytic drug is required for randomization into the study. Exclusion Criteria: * Modified Rankin score of 4 or more at randomization; * Refusal to provide consent; * Severe renal failure, with glomerular filtration rate (by CKD-EPI) estimated at \<15 mL/min/1.73 m2; * Severe liver failure (child C); * Indication for full-dose anticoagulation (for example, venous thromboembolism or atrial fibrillation); * Previous hemorrhagic stroke or history of intracranial hemorrhage; * Systemic treatment with a potent CYP 3A4 inhibitor (such as azole antifungals and protease inhibitors), or with a potent 3A4 inducer (such as rifampicin, phenytoin, phenobarbital, or carbamazepine); * History of inflammatory bowel disease or chronic diarrhea; * Prolonged treatment (\> 1 month) with immunosuppressants or systemic corticosteroids; * History of recurrent pneumonia (3 or more hospitalizations in the last 12 months); * Pregnancy or breastfeeding; * Any other comorbidity other than stroke and CV disease (e.g., metastatic cancer) that, in the investigator's opinion, has a significant impact on the 12-month survival.
