intravenous tissue plasminogen activator (IV tPA)

Intravenous tissue plasminogen activator (IV tPA) is a medication used to treat strokes caused by blood clots blocking blood flow to the brain. It works by dissolving the clot, restoring blood flow, and minimizing brain damage. This treatment is most effective when administered within a narrow time window, usually within 3 to 4.5 hours from symptom onset. IV tPA can significantly improve recovery outcomes if given promptly, but it also carries risks like bleeding, so careful evaluation by medical professionals is essential before administration.
