Quizplus · Accepted Answer

tPA (tissue plasminogen activator) is a medication that can be given to dissolve blood clots and restore blood flow to the affected part of the brain during an ischemic stroke. However, it can only be effective if given within 4.5 hours of the onset of symptoms. Infusing free radicals, inactivating GABA receptors, stimulating glutamate receptors, or promoting inflammatory reactions are not therapies for ischemic stroke and can potentially cause harm.
