Acute ischemic stroke is a leading cause of disability and mortality. The investigators' previous studies suggested levofloxacin to be a newly identified neuro-protective agent, which could reduce infarct volume and improve neurologic function in animal models. To evaluate the efficacy and safety of levofloxacin in treating acute ischemic stroke patients, the prospective, multicenter and randomized controlled trial was designed.
The purpose of this study is to determine the efficacy and safety of levofloxacin in treating acute ischemic stroke.
