Detailed explanation-1: -An IV injection of recombinant tissue plasminogen activator (TPA)-also called alteplase (Activase) or tenecteplase (TNKase)-is the gold standard treatment for ischemic stroke. An injection of TPA is usually given through a vein in the arm within the first three hours.
Detailed explanation-2: -For the 3 to 4.5 hours from the moment of the stroke, the benefits of tPA outweigh the risk. Studies show that after that window, the benefits of tPA drop significantly. Another factor that should be taken into consideration is the presence of a very large blood clot.
Detailed explanation-3: -If you get to the hospital within 3 hours of the first symptoms of an ischemic stroke, you may get a type of medicine called a thrombolytic (a “clot-busting” drug) to break up blood clots. Tissue plasminogen activator (tPA) is a thrombolytic. tPA improves the chances of recovering from a stroke.
