At a glance
Key differences
- Same class. Both Coumadin and Pradaxa are anticoagulants, so they work through the same broad mechanism. Differences between them tend to be about dosing, route, how selective they are, and side effects rather than what they target.
- Time on the market. Coumadin was first approved by the FDA in 1954, Pradaxa in 2010. That gives Coumadin roughly 56 more years of real-world use and long-term safety data.
- Who markets them. Coumadin is marketed by Bristol Myers Squibb; Pradaxa by Boehringer Ingelheim.

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.
