It has linear, predictable pharmacokinetics, achieves maximal concentration within 1-2 hours, is 50% renally excreted, and has a half life is 9-11 hours.</p>
<p>
Edoxaban was evaluated in a recent trial comparing warfarin in patients with atrial fibrillation.</p>
<p>
The primary end point or first stroke or systemic pulmonary embolic event occurred in <strong>1.5%</strong> with warfarin, compared with <strong>1.18% in the high dose edoxaban </strong>(HR 0.79; 97.5% CI 0.63-0.99, P<0.001). In the intention to treat there were trends favoring high dose edoxaban and unfavorable trends with the lower dose.</p>
<p>
The principal safety end point of <strong>major bleeding occurred in 3.43% with warfarin versus 2.75% </strong>with high dose edoxaban (HR 0.86; 95% CI 0.71-0.91, P<0.001). </p>
<p>
<strong>Bottom line</strong>: Both high dose (60 mg) and low dose (30 mg) edoxaban were non-inferior to warfarin with prevention of stroke or systemic emboli, and were associated with significantly lower rates of bleeding and death from cardiovascular causes.</p>
<p>
Currently it is approved for use in Japan.</p>
