About Xarelto®

Xarelto® is indicated for the prevention of venous thromboembolism (VTE) in adult patients undergoing elective hip or knee replacement surgery.1

Xarelto® belongs to a group of medicines called anticoagulants. It works by blocking the blood clotting Factor Xa and thereby reduces the tendency of the blood to form clots.1

Venous blood clots originate in the blood vessels that transport the blood back into the heart and from there to the lungs. Venous thromboembolism (VTE) can take the form of either a deep vein thrombosis (DVT), a blood clot in a deep vein (usually in the leg), or a pulmonary embolism (PE), a potentially life-threatening blood clot blocking a vessel in the lungs.14
  • A deep vein thrombosis (DVT) is a blood clot in a deep vein (usually in the leg) that partially or totally blocks the flow of blood.
  • A pulmonary embolism (PE) is a blood clot which breaks off and travels through the body, ultimately blocking a blood vessel in the lungs.

Healthy patients undergoing elective major orthopaedic surgery, such as total knee or total hip replacement, are at risk of venous blood clots due to factors such as vascular damage and reduced mobility.43 Venous blood clots occur in 40-60% of patients undergoing orthopaedic surgery who do not receive preventive care.61, 65

Recent guidelines recommend the routine use of anticoagulants for patients undergoing elective hip or knee replacement surgery.6

Fast Facts

  • The extensive clinical trial programme for Xarelto® covering acute and chronic indications makes it the most studied oral, direct Factor Xa inhibitor in the world today. Almost 50,000 patients are expected to be enrolled overall in the Xarelto® clinical development program.9
  • Venous blood clots kill more people in Europe each year than AIDS, breast cancer, prostate cancer, and road traffic accidents combined.46, 47
  • VTE causes over 500,000 deaths in Europe every year.46
  • An estimated 300,000 VTE-related deaths occur in the US each year.41
  • Almost all the hospital deaths resulting from PE are preventable.59

Factor Xa
Pivotal component of blood clotting cascade. Stimulates the production of thrombin, the enzyme in the coagulation cascade that promotes the formation of blood clots.
Major orthopaedic surgery
Major operations on the bones or joints including total hip or knee replacement surgery.
Formation of a clot inside a blood vessel.
Venous thromboembolism
A disease process beginning with a blood clot occurring within the venous system, including deep vein thrombosis and pulmonary embolism.
Pulmonary embolism
A potentially fatal condition caused by a blood clot blocking a vessel in the lung: usually the clot originates from a DVT in the legs. PE can result in permanent lung damage.

Activated Factor X, functioning as part of the prothrombinase complex on the surface of activated platelets, converts large amounts of prothrombin to thrombin, in the “thrombin burst.”

Embolus formation

Fragments of thrombi can break free to form potentially life-threatening pulmonary emboli.

Pulmonary embolus

Whole lung in which pulmonary arteries are obstructed by fresh (red) thrombus (circles).

Pulmonary embolism

The pathway of a pulmonary embolism (PE) from the lower half of the body: inferior vena cava, to right atrium, to right ventricle, to the pulmonary artery. This eventually obstructs blood flow to the lung. Patients with deep vein thrombosis (DVT) are at risk of PE, a life-threatening event.

Major veins of the lower extremity

The most common type of VTE is deep vein thrombosis (DVT), which occurs in veins deep within the muscles of the leg and pelvis.
