Randomized Controlled Trial
Effect of non-specific reversal agents on anticoagulant activity of dabigatran and rivaroxaban: a randomised crossover ex vivo study in healthy volunteers.
The new anticoagulants dabigatran and rivaroxaban can be responsible for haemorrhagic complications. As for any anticoagulant, bleeding management is challenging. We aimed to test the effect of all putative haemostatic agents on the anticoagulant activity of these new drugs using thrombin generation tests. ⋯ For both anticoagulants, lower doses of FEIBA, corresponding to a quarter to half the dose usually used, have potential reversal profile of interest. In conclusion, some non-specific reversal agents appear to be able to reverse the anticoagulant activity of rivaroxaban or dabigatran. However, clinical evaluation is needed regarding haemorrhagic situations, and a meticulous risk-benefit evaluation regarding their use in this context is required.
