Thrombolytic medicines are approved for the emergency treatment of stroke and heart attack. The most commonly used drug for thrombolytic therapy is tissue plasminogen activator (tPA), but other drugs can do the same thing.

Is rtPA the same as tPA?

tPA can be manufactured using recombinant biotechnology techniques; tPA produced by such means are referred to as recombinant tissue plasminogen activator (rtPA). Specific rtPAs include alteplase, reteplase, and tenecteplase. They are used in clinical medicine to treat embolic or thrombotic stroke.

What does alteplase do to your body?

Alteplase is a thrombolytic (THROM-bo-LIT-ik) drug, sometimes called a “clot-busting” drug. It helps your body produce a substance that dissolves unwanted blood clots. Alteplase is used to treat a stroke caused by a blood clot or other obstruction in a blood vessel.
