The drug that is considered "golden hour" for stroke is tissue plasminogen activator (tPA).
What is tPA?
tPA is a medication that dissolves blood clots. When a stroke occurs, a blood clot blocks blood flow to the brain. tPA can help to break up the clot and restore blood flow.
Why is tPA Important?
tPA is most effective when given within 3-4.5 hours of the onset of stroke symptoms. This timeframe is referred to as the "golden hour" because it represents the window of opportunity for the most effective treatment.
How is tPA Administered?
tPA is typically administered intravenously (through a vein) in a hospital setting.
Who is tPA for?
tPA is only appropriate for certain types of stroke, known as ischemic stroke, which is caused by a blood clot. It is not used for hemorrhagic stroke, which is caused by a bleeding vessel in the brain.
What are the Potential Risks of tPA?
Like any medication, tPA can have side effects. The most common side effects are bleeding and bruising. However, in rare cases, tPA can cause more serious complications, such as brain hemorrhage.
Important Considerations:
- Time is critical: The sooner tPA is administered after the onset of stroke symptoms, the more effective it is.
- Not all stroke patients are candidates for tPA: A doctor will determine if tPA is appropriate based on the type of stroke, the patient's medical history, and other factors.
