Tpa Clot Busting
Posted : admin On 4/11/2022Alteplase 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. TPA is a thrombolytic or a “Clot Buster” drug. This clot buster is used to break-up the clot that is causing a blockage or disruption in the flow of blood to the brain and helps restore the blood flow to the area of the brain. It is given by intravenous (IV), not by mouth. What tests are required? According to the American Stroke Association the most promising treatment for ischemic stroke is the clot-busting drug tPA (tissue plasminogen activator), given in the first three hours after the onset of symptoms. A 2011 study found that the typical cost of treatment with tPA is $2,200.
(Medical Xpress)—Ever since its introduction in the 1990s, the 'clot-busting' drug tPA has been considered a 'double-edged sword' for people experiencing a stroke. It can help restore blood flow. Happens when a clot blocks a vessel supplying blood to the brain. It's the most common type, accounting for 87% of all strokes. The treatment goal is to bust or remove the clot.

Thrombolytic therapy is the use of drugs to break up or dissolve blood clots, which are the main cause of both heart attacks and stroke.
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.
Ideally, you should receive thrombolytic medicines within the first 30 minutes after arriving at the hospital for treatment.
HEART ATTACKS
A blood clot can block the arteries to the heart. This can cause a heart attack, when part of the heart muscle dies due to a lack of oxygen being delivered by the blood.
Tpa Clot Buster Side Effects
Thrombolytics work by dissolving a major clot quickly. This helps restart blood flow to the heart and helps prevent damage to the heart muscle. Thrombolytics can stop a heart attack that would otherwise be larger or potentially deadly. Outcomes are better if you receive a thrombolytic drug within 12 hours after the heart attack starts. But the sooner treatment begins, the better the results.
The drug restores some blood flow to the heart in most people. However, the blood flow may not be completely normal and there may still be a small amount of muscle damaged. Further therapy, such as cardiac catheterization with angioplasty and stenting, may be needed.
Clot Buster Drugs
Your health care provider will base the decisions about whether to give you a thrombolytic medicine for a heart attack on many factors. These factors include your history of chest pain and the results of an ECG test.
Other factors used to determine if you are a good candidate for thrombolytics include:
- Age (older people are at increased risk of complications)
- Sex
- Medical history (including your history of a previous heart attack, diabetes, low blood pressure, or increased heart rate)
Generally, thrombolytics may not be given if you have:
- A recent head injury
- Bleeding problems
- Bleeding ulcers
- Pregnancy
- Recent surgery
- Taken blood thinning medicines such as Coumadin
- Trauma
- Uncontrolled (severe) high blood pressure
STROKES
Most strokes are caused when blood clots move to a blood vessel in the brain and block blood flow to that area. For such strokes (ischemic strokes), thrombolytics can be used to help dissolve the clot quickly. Giving thrombolytics within 3 hours of the first stroke symptoms can help limit stroke damage and disability.
The decision to give the drug is based upon:
- A brain CT scan to make sure there has not been any bleeding
- A physical exam that shows a significant stroke
- Your medical history
As in heart attacks, a clot-dissolving drug isn't usually given if you have one of the other medical problems listed above.
Thrombolytics are not given to someone who is having a stroke that involves bleeding in the brain. They could worsen the stroke by causing increased bleeding.
RISKS
Bleeding is the most common risk. It can be life threatening.
Minor bleeding from the gums or nose can occur in approximately 25% of people who receive the drug. Bleeding into the brain occurs approximately 1% of the time. This risk is the same for both stroke and heart attack patients.
If thrombolytics are felt to be too dangerous, other possible treatments for clots causing a stroke or heart attack include:
Tpa Clot Buster Risks
- Removal of the clot (thrombectomy)
- A procedure to open narrowed or blocked blood vessels that supply blood to the heart or the brain

Heart attacks and strokes are medical emergencies. The sooner treatment with thrombolytics begins, the better the chance for a good outcome.
