Stroke drugs, to be given within 3-4.5 hours from stroke:
A stroke is an interruption of the blood supply to any part of the brain. A stroke is sometimes called a "brain attack."
TPA CLOT BUSTER FOR IMMEDIATE TREATMENT OF STROKE Tissue plasminogen activator (tPA) is a thrombolytic agent (clot-busting drug). It's approved for use in certain patients having a heart attack or stroke. The drug can dissolve blood clots, which cause most heart attacks and strokes. tPA is the only drug approved by the U.S. Food and Drug Administration for the urgent treatment of ischemic stroke.
Studies have shown that tPA and other clot-dissolving agents can reduce the amount of damage to the heart muscle and save lives. However, to be effective, they must be given within a few hours after symptoms begin. Administering tPA or other clot-dissolving agents is complex and is done through an intravenous (IV) line in the arm by hospital personnel. tPA can only be given to a person within the first three hours after the start of stroke symptoms tPA or other thrombolytics can reduce disability from a heart attack or stroke, but there is also a higher risk of bleeding.
