Idarucizumab is the antidote to dabigatran. Perhaps the hardest thing about it is saying its name. Eye-da-roo-ciz-oo-mab or praxbind until to comes off label. It is a humanised monoclonal antibody fragment (Fab) that binds to dabigatran with very high affinity (340x fold more than dabigatran binds to thrombin).
