Abstract

The oral direct Xa inhibitor rivaroxaban (Xarelto) shows great promise for prevention of venous thromboembolic events after major elective orthopedic surgery. Its consistent and predictable pharmacokinetics and pharmacodynamics across a wide range of patient populations allow administration with fixed dosing and with no coagulation monitoring. In 4 orthopaedic surgery clinical trials (12,700 patients), 10mg postoperative (6-10 hours after the end of surgery) dose, once daily, of oral rivaroxaban, achieved superior efficacy and similar safety to enoxaparin, whatever the dose of enoxaparin. Indeed, 40 mg once a day in Europe and 30 mg bid in US of enoxaparin were compared to the same dose of 10mg once daily of rivaroxaban. Furthermore, there is no difference according to liver enzymes elevation and cardio-vascular adverse events. Although the risk of spinal haematoma after neuraxial anaesthesia is rare, it is increased by concomitant use of anticoagulants. In orthopedic surgery trials with rivaroxaban to date, complications such as spinal haematoma have not been reported. The pharmacokinetic profile of rivaroxaban suggests that concurrent use with neuraxial anaesthesia should require no further precautions than currently necessary with low-molecular-weight heparin.
