The most commonly used [[anticoagulants]] in clinical practice, [[warfarin]] and the [[heparin]] series of anticoagulants and [[fondaparinux]], act to inhibit the action of Factor Xa in various degrees.
 
Traditional models of coagulation developed in the 1960s envisaged two separate cascades, the extrinsic [[tissue factor|(tissue factor (TF))]] pathway and the intrinsic pathway. These pathways converge to a common point, the formation of the Factor Xa/Va complex which together with [[calcium]] and bound on a [[phospholipids]] surface generate [[thrombin|thrombin (Factor IIa)]] from [[prothrombin|prothrombin (Factor II)]].
