Abstract
Rivaroxaban is a once-daily oral anticoagulant currently marketed for the prevention of stroke and systemic embolism in patients with non-valvular atrial fibrillation. This indication is largely based on the results of the ROCKET-AF trial. Although these results are robust, studies performed in clinical practice are necessary to confirm these data in real-life patients. These studies have shown rates of stroke and bleeding similar to that found in ROCKET-AF. As an anticoagulant, attention should be paid to making a correct prescription of rivaroxaban, particularly in fragile patients, to reduce the risk of bleeding. In addition, a number of studies have shown that rivaroxaban is cost-effective in clinical practice. Moreover, rivaroxaban is a good alternative to warfarin in patients undergoing elective cardioversion or atrial fibrillation ablation.

Chronic oral anticoagulation is required in the vast majority of patients with atrial fibrillation (AF) to prevent thromboembolic complications.
Vitamin K antagonists have many disadvantages that limit their use in clinical practice. Moreover, the available evidence about vitamin K antagonists is mainly limited to warfarin.
Rivaroxaban is a once-daily, direct factor Xa inhibitor currently approved for the prevention of stroke and systemic embolism in patients with non-valvular AF and at least one risk factor for stroke.
This indication is largely based on the results of ROCKET-AF.
The information provided by clinical trials is very relevant. However, patients included in randomized clinical trials may be quite different from those of clinical practice.
Studies that included real-life patients showed similar rates of stroke and bleeding to that found in ROCKET-AF.
Particular attention should be paid to making a correct prescription of rivaroxaban, particularly in fragile patients (i.e., elderly, renal insufficiency) to reduce the risk of bleeding.
A number of studies have shown that rivaroxaban reduces hospital length of stay and that it is cost-effective option compared with warfarin in clinical practice.
Rivaroxaban is also a good alternative to warfarin in patients undergoing elective cardioversion or AF ablation.
