This review evaluates the research undertaken in the last six years on the use of new oral anticoagulants for stroke prevention in atrial fibrillation and provides evidence-based answers to common clinical questions. Two types of new oral anticoagulants – direct thrombin (IIa) inhibitors, and Xa inhibitors – are currently available. These drugs have similar pharmacokinetics and pharmacodynamics. They are more predictable than, though in many respects comparable to, warfarin. They do not require frequent laboratory tests, nor do they have a narrow therapeutic window.
