Oral Anticoagulant │ Anticoagulation Therapy

Oral Anticoagulant UTA

Studies have demonstrated an increase in the anticoagulant efficacy of heparin-based drugs as their selectivity for Factor Xa increases.26

Xarelto® is the first direct oral Factor Xa inhibitor (approved in the European Union for the prevention of venous thromboembolism [VTE] in adult patients undergoing elective hip or knee replacement surgery), a new generation of investigational anticoagulants targeting the prevention and treatment of acute and chronic thromboembolic diseases. Extensive studies already involve more than 32,000 patients, and more than 60,000 patients are expected to be evaluated when the studies are completed. This establishes Xarelto® as the most studied anticoagulant of its kind to date.64, 68

Oral Anticoagulation Therapy

The advantages of Xarelto® include oral administration without the need for routine coagulation monitoring. Other therapies, such as unfractionated heparins (UFHs), low-molecular-weight heparins (LMWHs), and fondaparinux, can be administered only subcutaneously or intravenous. And oral vitamin K antagonists (VKAs) have a narrow therapeutic window and significant interactions with food and other drugs, leading to the need for strict monitoring.7, 8, 27, 30
