Dabigatran belongs to a class of anticoagulants known as direct oral anticoagulants (DOACs). Other DOACs include rivaroxaban (Xarelto), apixaban (Eliquis), and edoxaban (Savaysa). These drugs differ in their mechanisms of action, dosing regimens, and clinical trial data [3]. For example, dabigatran directly inhibits thrombin, while rivaroxaban and apixaban are Factor Xa inhibitors [3].
