Xarelto (Rivaroxaban) - Summary




Discontinuing XARELTO places patients at an increased risk of thrombotic events. An increased rate of stroke was observed following XARELTO discontinuation in clinical trials in atrial fibrillation patients. If anticoagulation with XARELTO must be discontinued for a reason other than pathological bleeding, consider administering another anticoagulant [see Dosage and Administration, Warnings and Precautions, and Clinical Studies].


Epidural or spinal hematomas have occurred in patients treated with XARELTO who are receiving neuraxial anesthesia or undergoing spinal puncture. These hematomas may result in long-term or permanent paralysis. Consider these risks when scheduling patients for spinal procedures. Factors that can increase the risk of developing epidural or spinal hematomas in these patients include:

  • use of indwelling epidural catheters
  • concomitant use of other drugs that affect hemostasis, such as non-steroidal anti-inflammatory drugs (NSAIDs), platelet inhibitors, other anticoagulants
  • a history of traumatic or repeated epidural or spinal punctures
  • a history of spinal deformity or spinal surgery

[see Warnings and Precautions (5.2, 5.3) and Adverse Reactions].

Monitor patients frequently for signs and symptoms of neurological impairment. If neurological compromise is noted, urgent treatment is necessary [see Warnings and Precautions].

Consider the benefits and risks before neuraxial intervention in patients anticoagulated or to be anticoagulated for thromboprophylaxis [see Warnings and Precautions].



Rivaroxaban, a factor Xa inhibitor, is the active ingredient in XARELTO Tablets.

Reduction of Risk of Stroke and Systemic Embolism in Nonvalvular Atrial Fibrillation

XARELTO (rivaroxaban) is indicated to reduce the risk of stroke and systemic embolism in patients with nonvalvular atrial fibrillation.

There are limited data on the relative effectiveness of XARELTO and warfarin in reducing the risk of stroke and systemic embolism when warfarin therapy is well-controlled [see Clinical Studies].

Prophylaxis of Deep Vein Thrombosis

XARELTO (rivaroxaban) is indicated for the prophylaxis of deep vein thrombosis (DVT), which may lead to pulmonary embolism (PE) in patients undergoing knee or hip replacement surgery.

Published Studies Related to Xarelto (Rivaroxaban)

Oral rivaroxaban after symptomatic venous thromboembolism: the continued treatment study (EINSTEIN-extension study). [2011]
Over recent years, research on anticoagulant drugs has been guided by the requirement for convenient administration and a wide therapeutic window to allow fixed dosing without the need for coagulation monitoring. Rivaroxaban is the first of a new class of anticoagulant drugs, the direct, selective inhibitors of Factor Xa.

[2011]
BACKGROUND: Although therapy with aspirin or aspirin plus a thienopyridine reduces the incidence of long-term adverse cardiovascular events among patients with acute coronary syndrome (ACS), there remains a significant residual risk of cardiovascular death, recurrent myocardial infarction (MI), and stroke...

Clinical Trials Related to Xarelto (Rivaroxaban)

Rivaroxaban for Treatment of Patients With Suspected or Confirmed Heparin-Induced Thrombocytopenia [Recruiting]
Heparin is an anticoagulant (blood thinner) that is commonly used to treat patients with heart attacks and patients with blood clots in their legs or lungs (venous thrombosis). Some patients develop an allergic reaction to heparin, a condition called heparin-induced thrombocytopenia (HIT). HIT makes blood clot, which is the opposite of what heparin was designed to do. These blood clots can lead to heart attacks, strokes, limb amputations, and death. The objective of this 200 patient study is to determine if a new blood thinner called rivaroxaban (Xarelto) can be used to treat HIT. Rivaroxaban can be taken by mouth, does not require blood testing, and had a low risk of bleeding when it was used to treat blood clots in other clinical trials. If this study shows that rivaroxaban can be used to treat HIT, there will be two very important benefits. For patients with HIT, the benefit will be having a safe, and easy-to-use drug to protect them from developing further life or limb-threatening blood clots. For the Canadian health care system, the benefit will be having a drug that is much less expensive than the drugs currently used to treat HIT.

Xarelto [SPAF] Post-marketing Surveillance in Japan [Recruiting]
This study is a regulatory post-marketing surveillance in Japan, and it is a local prospective and observational study of patients who have received Xarelto for SPAF.

The objective of this study is to assess safety and effectiveness of Xarelto using in real clinical practice.

A total of 10,000 patients are to be enrolled and assessed in 2 years standard observational period. An annual follow-up survey will be conducted for 5 years at the longest after standard observational period.

Rivaroxaban for the Prevention of Major Cardiovascular Events in Coronary or Peripheral Artery Disease [Not yet recruiting]
The primary purpose of this study is to evaluate whether treatment with rivaroxaban and aspirin or rivaroxaban alone is better than aspirin alone in prevention of heart attacks, stroke or cardiovascular death in patients with coronary or peripheral artery disease.

Xarelto [SPAF-QOL] Post-marketing Surveillance in Japan [Recruiting]
The objective of this study is to understand if Rivaroxaban can improve treatment satisfaction of Warfarin patients and assess the safety and effectiveness of Xarelto in real clinical practice.

A total of 725 patients are to be enrolled and followed for a 6 months. period. QOL survey will be conducted at month 0, 3, 6 using ACTS/TSQM.

This study is categorized as a regulatory post-marketing surveillance in Japan, and it is a local prospective and observational study of patients who have received Xarelto for SPAF.

Explore the Efficacy and Safety of Once-daily Oral Rivaroxaban for the Prevention of Cardiovascular Events in Subjects With Nonvalvular Atrial Fibrillation Scheduled for Cardioversion [Recruiting]
A study for patients with abnormal heart rhythm (atrial fibrillation) who need to undergo cardioversion (procedure to restore normal heart rhythm). The study will compare patients assigned randomly (like flipping a coin) to either Rivaroxaban or vitamin K antagonist (VKA). The study will measure common medical outcomes for this type of patient such as bleeding and stroke.
