Antikoagulation

Abstract

Anticoagulant drugs belong to the group of antithrombotic agents and are successfully used in the prophylaxis and treatment of thromboembolic disorders. The use of anticoagulants in the prevention of deep venous thrombosis has significantly lowered the risk of venous thrombosis and fatal pulmonary embolisms even in high-risk situations such as orthopedic surgery. Anticoagulants play a central role in the treatment of acute venous thrombosis and in the prevention of recurrent events. Long-term anticoagulation therapy with orally active anticoagulants significantly reduces the risk of thromboembolic complications in patients showing cardiac arrhythmias. Whereas a few years ago heparins and vitaminK antagonists were the dominant anticoagulants, today a wide range of anticoagulants with improved pharmacological profiles are available. It remains an open question whether these new anticoagulants will improve the efficacy, safety, and acceptance of anticoagulant treatment approaches.
