RT Journal Article SR Electronic A1 Kuznar, Wayne T1 Promising Agent Identified as Specific Antidote to Factor Xa Inhibition JF MD Conference Express YR 2014 FD SAGE Publications VO 14 IS 21 SP 17 OP 17 DO 10.1177/155989771421010 UL http://mdc.sagepub.com/content/14/21/17.abstract AB Antidotes to Factor Xa inhibitors are under development and should enhance the safety of the new oral anticoagulant (NOAC) agents. Reversal of a NOAC is necessary in certain circumstances, such as a spontaneous or provoked hemorrhage (rate of 10% to 20% in Phase 3 trials), an emergency or invasive procedure that requires the rapid reversal of anticoagulation, or serious bleeding in a critical organ.
