A study involving a test group confirmed the existence of a dose-dependent inhibition of X-factor activity by rivaroxaban, an active active substance of Xarelto, it was found that it increases APTT( partial thromboplastin activation).

Indicators may differ if Neoplastin® or HepTest® is used for analysis. The device data are taken in seconds, since the INR is calibrated and validated solely for coumarins, therefore it is inadmissible to use other anticoagulants.

Like all direct anticoagulants Xarelto exert direct influence on thrombin to reduce its activity. The drug is an inhibitor of thrombin, prothrombin deactivators, due to which they functionally delay the development of thrombus formation.
