How Stroke Medications Work

Stroke medications aim to restore blood flow to the brain, reduce damage, and improve outcomes. The gold standard for acute ischemic stroke treatment is Tissue Plasminogen Activator (tPA), which works by dissolving blood clots that block blood vessels in the brain.

Gold Standard: Tissue Plasminogen Activator (tPA)

• tPA activates plasminogen to form plasmin, a proteolytic enzyme that breaks down fibrin clots
• Restores blood flow to the affected area of the brain
• Improves outcomes when administered within 3-4.5 hours of symptom onset

Alternatives and Adjuncts

• Mechanical thrombectomy: a minimally invasive procedure to remove blood clots from brain vessels
• Endovascular stenting: placement of a stent in the affected vessel to keep it open
• Anticoagulation therapy: medications that prevent new clot formation, often used in conjunction with tPA or as an alternative for patients who do not respond to tPA

Importance of Early Diagnosis and Treatment

Early recognition of stroke symptoms and prompt treatment are critical. Diagnostic tests such as Computed Tomography (CT) scan, Magnetic Resonance Imaging (MRI) scan, and Diffusion-Weighted Imaging (DWI) help identify the type and location of the stroke. Identifying risk factors like high blood pressure, diabetes mellitus, smoking, and family history can also inform treatment decisions.
