Understanding Direct Oral Anticoagulants (DOACs)

Direct oral anticoagulants (DOACs) such as Apixaban, Dabigatran, Edoxaban, and Rivaroxaban are increasingly prescribed for conditions like atrial fibrillation and venous thromboembolism. These medications have specific pharmacokinetic properties, notably a half-life of about 10 to 12 hours, and a peak onset of action around two hours after administration. This quick action necessitates careful perioperative management, especially for patients scheduled for surgery, as clinicians must determine the appropriate timing for stopping or resuming these medications. Understanding the distinct differences between DOACs and traditional anticoagulants like warfarin is essential, particularly given the safety profile of DOACs, which tends to involve less bleeding and eliminates the need for routine blood monitoring.
