Both are anticoagulants. Here is how Xarelto and Pradaxa compare on class, mechanism, dosing, approval and supply.
XARELTO is a factor Xa inhibitor indicated: to reduce risk of stroke and systemic embolism in nonvalvular atrial fibrillation ( 1.1 ) for treatment of deep vein thrombosis (DVT) ( 1.2 ) for treatment of pulmonary embolism (PE) ( 1.3 ) for reduction in the risk of recurrence of DVT or PE ( 1.4 ) for the prophylaxis of DVT, which may lead to PE in patients undergoing knee or hip replacement surgery ( 1.5 ) for prophylaxis of venous thromboembolism (VTE) in acutely ill medical patients ( 1.6 ) to reduce the risk of major cardiovascular events in patients with coronary artery disease (CAD) ( 1.7 ) to reduce the risk of major thrombotic vascular events in patients with peripheral artery disease (PAD), including patients after recent lower extremity revascularization due to symptomatic PAD ( 1.8 ) for treatment of VTE and reduction in the risk of recurrent VTE in pediatric patients from birth…
PRADAXA Oral Pellets are a direct thrombin inhibitor indicated: For the treatment of venous thromboembolic events (VTE) in pediatric patients aged 3 months to less than 12 years of age who have been treated with a parenteral anticoagulant for at least 5 days ( 1.1 ) To reduce the risk of recurrence of VTE in pediatric patients aged 3 months to less than 12 years of age who have been previously treated ( 1.2 ) 1.1 Treatment of Venous Thromboembolic Events in Pediatric Patients PRADAXA Oral Pellets are indicated for the treatment of venous thromboembolic events (VTE) in pediatric patients aged 3 months to less than 12 years of age who have been treated with a parenteral anticoagulant for at least 5 days. 1.2 Reduction in the Risk of Recurrence of Venous Thromboembolic Events in Pediatric Patients PRADAXA Oral Pellets are indicated to reduce the risk of recurrence of VTE in pediatric patie…
12.1 Mechanism of Action XARELTO is a selective inhibitor of FXa. It does not require a cofactor (such as Anti-thrombin III) for activity. Rivaroxaban inhibits free FXa and prothrombinase activity. Rivaroxaban has no direct effect on platelet aggregation, but indirectly inhibits platelet aggregation induced by thrombin. By inhibiting FXa, rivaroxaban decreases thrombin generation.
12.1 Mechanism of Action Dabigatran and its acyl glucuronides are competitive, direct thrombin inhibitors. Because thrombin (serine protease) enables the conversion of fibrinogen into fibrin during the coagulation cascade, its inhibition prevents the development of a thrombus. Both free and clot-bound thrombin, and thrombin-induced platelet aggregation are inhibited by the active moieties.
Which medicine is right for a given person depends on their diagnosis, other conditions, other medicines, kidney and liver function, pregnancy, and cost or reimbursement — none of which this page knows. Two drugs in the same class are not automatically interchangeable. Never start, stop or switch a prescription medicine on the basis of a web page; that decision belongs to you and your clinician or pharmacist.
The facts on this page are pulled directly from official U.S. FDA datasets — they are not written from memory. Each field below names the dataset it came from, so you can check it yourself.
Plain-English summaries and drug-class explainers are written and reviewed by the Priya Life Science editorial team, led by Sreepriya Prasannan (MSc Digital Transformation of Life Sciences (Innopharma Education / Griffith College); MSc & BSc Botany). Data is retrieved automatically from the sources above and cross-checked with AI-assisted verification (Anthropic's Claude) — brand and generic names are matched against the exact FDA product record so that a combination product or a different formulation cannot be mistaken for the drug on this page. An editor reviews the result before publication. We describe this in full in our editorial standards and corrections policy. The FDA data on this page was last retrieved on 6 Aug 2026.
