Due to different mechanisms, treatment also is different:
Clot busters The most recent advance in treatment for ischemic stroke is the “clot-busting” drug tPA (tissue plasminogen activator), which must be administered within four and a half hours of the onset of symptoms. However, for best results it should be given as early as possible. Administering tPA is done through an intravenous (IV) line in the arm by hospital personnel. Strict protocols govern the administration of the above treatment. If given promptly, tPA can significantly reduce the effects of stroke and reduce permanent disability. Generally, only about 5-10 percent of strokes will qualify to receive tPA.
