Direct oral anticoagulants were introduced in the market to simplify the anticoagulation treatment and eventually, replace warfarin. As previously discussed, these new agents have some advantages over warfarin. One of those advantage is that all DOACs are administered in fixed doses, only adjusted for specific factors like renal functions (in some cases). Since 2008, the US and EU regulatory bodies have approved several DOACs for specific indications based on their clinical trials demonstrating non-inferiority to warfarin. The availability of DOACs have changed the way stroke prevention in AF is managed.
