New oral anticoagulants, acting either as direct factor-Xa or thrombin inhibitors, have been evaluated for the acute and long-term treatment of venous thromboembolism (VTE). Dabigatran and rivaroxaban are as effective as conventional therapy (heparin/vitamin K antagonists) without safety concerns. Rivaroxaban allows a single-drug regimen even in patients with pulmonary embolism, while dabigatran requires 5-7 days of initial heparin treatment. The results of clinical trials with apixaban and edoxaban will become available in the coming months. Rivaroxaban, apixaban and dabigatran are more effective than placebo for the extended treatment of VTE. Apixaban is effective in both therapeutic and prophylactic doses. Considering both efficacy and bleeding complications, all these agents have a favorable net clinical benefit. Dabigatran is as effective and safe as warfarin for the extended treatment of VTE. It is conceivable that the new oral anticoagulants will become the standard therapy for VTE in the next years.
