Apixaban babban zaɓi ne da mai hanawa na Factor Xa tare da ƙimar Ki na 0.08 nM da 0.17 nM a cikin mutum da zomo, bi da bi [1].

Factor X, wanda kuma aka sani da eponym Stuart-Prower factor, wani enzyme ne na cascade na coagulation.An kunna Factor X, ta hanyar hydrolysis, zuwa cikin factor Xa ta biyu factor IX.Factor Xa shine nau'in da aka kunna na coagulation factor thrombokinase.
