About Edoxaban

What it is

Edoxaban is a direct oral anticoagulant (DOAC): it blocks factor Xa, a central clotting enzyme, so blood takes longer to clot. Taken once a day without regular blood tests, it is used to lower the chance of stroke in atrial fibrillation and to treat clots in the legs and lungs. It is sold as Savaysa and Lixiana.

How genes come into it

Edoxaban is cleared about half by the kidneys and half by other routes, with little broken down by CYP3A4; it is a substrate of the transporter ABCB1 and is taken into the liver partly by SLCO1B1. Studies have looked at ABCB1, CYP3A5, POR and SLCO1B1 for its blood levels, with small effects. There is no CPIC or DPWG guideline.
