Feb 20, 2023 · Continuing Education Activity. 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 ...

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.

- Summary
A protein that naturally occurs in the body, tPA can be found on endothelial cells—the cells that line blood vessels. It activates the conversion of plasminogen to plasmin, an enzyme responsible for the breakdown of clots. This helps restore blood flow that would otherwise remain impeded. An experienced medical team can administer tPA in its powerf...
Prior to receiving treatment with tPA, you should expect your healthcare provider to review your medical history and order a brain computerized tomography(CT) scan. This is because there are several medical conditions that make it too dangerous for you to receive tPA. If you have any of these conditions, not only would tPA not help you, it could ca...
Treatment with tPA has been effective for people with an ischemic stroke as long as it is received intravenously within up to 4.5 hours of the onset of symptoms. In contrast, endovascular treatment to remove the clot or deliver tPA at the site of the clot is considered for up to 24 hours after a stroke.
While tPA has been shown to be beneficial in the treatment of stroke, there are risks associated with tPA treatment—even for people who have been medically cleared to receive it. It is a powerful blood thinner, and serious side effects may occur, including the following: 1. Hemorrhage (bleeding) affecting the brain: Causes headaches, weakness, conf...
The best way to maximize the chances of receiving the most effective treatment for a stroke is to get to the emergency room as soon as possible if you believe a stroke may be occurring. Symptoms of a stroke include: 1. Trouble understanding words or speaking 2. Numbness of the arm, face, or leg 3. Blurred or blackened vision in one or both eyes 4. ...
The use of tPA medication to break up clots in blood vessels has offered benefits to thousands of people since its use was first approved, but it can't be used in all cases. It's important to recognize the signs and symptoms of stroke to ensure treatment begins as quickly as possible.

There are two main plasminogen activators: urokinase (uPA) and tissue plasminogen activator (tPA). Tissue plasminogen activators are used to treat medical conditions related to blood clotting including embolic or thrombotic stroke, myocardial infarction, and pulmonary embolism. [1]
