Which medication is often prescribed for secondary prevention after ischemic stroke?

Antiplatelet agents, such as aspirin, are commonly prescribed for secondary prevention after an ischemic stroke due to their effectiveness in reducing the risk of subsequent strokes. After an ischemic event, the primary concern is preventing another stroke, which can occur if blood clots form and impede blood flow to the brain again. Aspirin works by inhibiting platelet aggregation, thereby reducing the likelihood of clot formation. This makes it a vital component in the long-term management of patients who have experienced an ischemic stroke, especially for those who have atherosclerotic disease.

In contrast, anticoagulants are typically reserved for specific circumstances, such as patients with atrial fibrillation, rather than general secondary prevention. Thrombolytics are utilized in acute stroke settings to dissolve clots and are not used for ongoing prevention after an ischemic stroke. Beta-blockers, while important for managing hypertension and heart issues, do not specifically address the prevention of future strokes in the same manner as antiplatelet agents. Thus, the role of antiplatelet medications is well-established and supported by clinical guidelines, making them a cornerstone in secondary prevention following an ischemic stroke.
