text Factor Xa (aka Factor X heavy chain), a cleavage product of coagulation factor X (F10), is a vitamin K-dependent glycoprotein able to convert prothrombin to thrombin during the blood clotting process. Factor Xa is a target for direct oral anticoagulant (DOAC) drugs that are direct factor Xa inhibitors (the so-called 'xabans') which are used in the treatment and prevention of thromboembolic disorders (Galanis et al. 2014). Rivaroxaban (brand name Xarelto) was the first medically approved drug of this class (Abrams & Emerson 2009, Misselwitz et al. 2011). Rivaroxaban binds to and inhibits both free factor Xa and factor Xa bound in the prothrombinase complex (Roehrig et al. 2005). Other 'xabans' such as apixaban (Bhanwra & Ahluwalia 2014), edoxaban (Minor et al. 2015), eribaxaban (Bondarenko et al. 2013) and betrixaban (Zhang et al. 2009) share a similar mechanism of action to rivaroxaban (Nutescu et al. 2016).
