Alteplase (t-PA) is an effective medication for acute ischemic stroke. When given within 3 hours, treatment with tpa significantly improves the probability of a favourable outcome versus treatment with placebo. [citation needed] The outcome of brain ischemia is influenced by the quality of subsequent supportive care.
Protocol guidelines require its use intravenously within the first three hours of the event, after which its detriments may outweigh its benefits. For example, the Canadian Stroke Network guideline states "All patients with disabling acute ischemic stroke who can be treated within 4.5 hours of symptom onset should be evaluated without delay to ...
Stroke: Thrombolysis reduces major disability or death when given within 3 hours (or perhaps even 6 hours) of ischaemic stroke onset when there are no contraindications to treatment. [2] [3] [4] Massive pulmonary embolism.
Typically, tissue plasminogen activator may be administered within 3 to 4.5 hours of stroke onset if the patient is without contraindications (i.e. a bleeding diathesis such as recent major surgery or cancer with brain metastases). High dose aspirin can be given within 48 hours. For long term prevention of recurrence, medical regimens are ...
Alteplase, sold under the brand name Activase among others, is a biosynthetic form of human tissue-type plasminogen activator (t-PA). It is a thrombolytic medication used to treat acute ischemic stroke, acute ST-elevation myocardial infarction (a type of heart attack), pulmonary embolism associated with low blood pressure, and blocked central venous catheter.

If any one of the three tests shows abnormal findings, the patient may be having a stroke and should be transported to a hospital as soon as possible. The CPSS was derived from the National Institutes of Health Stroke Scale developed in 1997 at the University of Cincinnati Medical Center for prehospital use.

This is present in both familial and sporadic AD, making it a more inclusive model. Additionally, the level of Aβ can be controlled, making it an ideal candidate for AD investigation. However, damage to the brain tissue during ICV injection must be minimized to prevent neuronal injury. This requires a highly trained individual or surgeon. [3]
