Answer

When no cause for recurrent strokes can be found, antiplatelet therapy—eg, with aspirin, ticlopidine, clopidogrel, or aspirin plus extended-release dipyridamole (Aggrenox)—is generally recommended instead of anticoagulation therapy.

As a result, patients entering the rehabilitation phase of their hospital course may be prescribed an anticoagulant, clopidogrel, or aspirin. The selection of these agents is dependent on the etiology of the posterior cerebral artery (PCA) stroke, associated complications, comorbidities, and prior medical history. These medications are used to prevent further cerebral vascular ischemic events.
