In recent years, the options for anticoagulant therapy have examined new direct oral anticoagulants (DOACs) comprising direct thrombin inhibitors (dabigatran) and direct factor Xa inhibitors (rivaroxaban, apixaban, and edoxaban). These agents represent further progress towards the ideal anticoagulant drug and thus towards a safe and effective antithrombotic therapy. The ideal anticoagulant is oral and has a wide therapeutic range, predictable pharmacokinetics and pharmacodynamics, a rapid onset of action, an available antidote, minimal side effects, and minimal interactions with other drugs or food. This review addresses the practical considerations for physicians in DOAC use, including indication, dosage, monitoring, pharmacokinetic profile, drug-drug interaction, and reversal of direct anticoagulation effects in case of bleeding.
