- Tissue plasminogen activator (tPA) is a drug given through a vein to help break up a blood clot so that blood flow can return to normal. It is used for the emergency treatment of ischemic stroke, which occurs when a blood clot interrupts blood flow to a region of the brain. The timely administration of tPA can save lives.

Oct 6, 2023 · tPA is a drug that dissolves blood clots in the brain and restores blood flow after a stroke. Learn about its benefits, risks, and how to get it in time.
Feb 20, 2023 · Tissue plasminogen activator (tPA) is classified as a serine protease (enzymes that cleave peptide bonds in proteins). It is thus one of the essential components of the dissolution of blood clots. Its primary function includes catalyzing the conversion of plasminogen to plasmin, the primary enzyme involved in dissolving blood clots. Recombinant ...

Apr 30, 2024 · Learn about the tests and treatments for ischemic and hemorrhagic strokes, including recombinant tissue plasminogen activator (TPA). TPA is an IV injection that can dissolve the clot causing the stroke within 4.5 hours.
Tissue-type plasminogen activator, short name tPA, is a protein that facilitates the breakdown of blood clots. It acts as an enzyme to convert plasminogen into its active form plasmin, the major enzyme responsible for clot breakdown. It is a serine protease (EC 3.4.21.68) found on endothelial cells lining the blood vessels.

Recombinant human tissue-type plasminogen activator (t-PA); produces local fibrinolysis. Promotes thrombolysis by converting plasminogen to plasmin; plasmin degrades fibrin and fibrinogen. Absorption. Onset: Coronary thrombolysis occurs in 30 min; reaches peak response at 60 min. Peak plasma time: 20-40 min. Distribution. Vd: 27-53 L. Metabolism
Known by the generic name alteplase and marketed as Activase® (Genentech), tPA is given to patients through an IV in the arm, and it works by dissolving blood clots that block blood flow to the brain.
