Rho‐associated kinase (ROCK) is an emerging target in acute ischemic stroke. Early pre‐hospital treatment with ROCK inhibitors may improve their efficacy, but their antithrombotic effects raise safety concerns in hemorrhagic stroke, precluding use prior to neuroimaging. Therefore, we tested whether ROCK inhibition affects the bleeding times, and worsens hematoma volume in a model of intracerebral hemorrhage (ICH) induced by intrastriatal collagenase injection in mice. Tail bleeding time was measured 1 h after treatment with isoform‐nonselective inhibitor fasudil, or ROCK2‐selective inhibitor KD025, or their vehicles. In the ICH model, treatments were administered 1 h after collagenase injection. Although KD025 but not fasudil prolonged the tail bleeding times, neither drug expanded the volume of ICH or worsened neurological deficits at 48 h compared with vehicle. Although more testing is needed in aged animals and comorbid models such as diabetes, these results suggest ROCK inhibitors may be safe for pre‐hospital administration in acute stroke.
