Rivaroxaban and Apixaban Reduce Hemorrhagic Transformation After Thrombolysis by Protection of Neurovascular Unit in Rat

Abstract

This study shows a lower risk of intracerebral hemorrhage after tissue-type plasminogen activator treatment in rats with ischemic stroke that are pretreated with rivaroxaban and apixaban compared with pretreatment with warfarin. Reducing neurovascular dissociation by rivaroxaban and apixaban compared with warfarin could partly explain a reduction in hemorrhagic complications reported in clinical studies.
