The option regarding edoxaban is correct because it is recommended that patients receive at least 5 days of injectable anticoagulation, usually enoxaparin or unfractionated heparin, before starting edoxaban. This is particularly important in situations where there is a need for rapid anticoagulation, such as in patients with atrial fibrillation and the presence of thrombosis or in patients with venous thromboembolism.

For edoxaban, the pre-treatment with injectable anticoagulants ensures that there is immediate anticoagulation coverage while the oral agent is being initiated, as it requires a building up of therapeutic levels in the system. This approach is critical because edoxaban, like other Factor Xa inhibitors, does not provide immediate anticoagulation effects after the first dose, which can be essential in managing acute thromboembolic events.

Dabigatran, rivaroxaban, and apixaban have different initiation protocols where immediate injectable anticoagulation may not be necessary, and they can often be started without the need for prior anticoagulation therapy, depending on the specific clinical scenarios. This distinction is significant and highlights the unique considerations required in the management of anticoagulation therapy with different medications.
