What is medicinal therapy for stroke prevention?

Blood thinners: Most strokes are caused by a brain infarction because of cholesterol plaques clotted producing obstruction to the blood flow to the tissue of a area of the brain. Less likely a hemorrhage in the brain. We use aspirin, Aggrenox , plavix, (clopidogrel) warfarin or Pradaxa as "blood thinners" to prevent strokes. We have to control blood pressure with meds too.

In Primary Stroke: Prevention (ie in someone who has not had a stroke, and is keen to avoid one) we modify risk factors. If indicated, consider medication to lower blood pressure (ACE inhibitor / Calcium Channel Blocker etc), or to lower blood cholesterol (Statin). Antiplatelet drugs (Aspirin) have an unclear role in Primary Prevention. Anticoagulants (Warfarin or NOAC) if Atrial Fibrillation and high CHADSVASC2.
