Study Notes
Secondary Prevention of Ischemic Stroke
- Secondary prevention of ischemic stroke aims to prevent recurrence.
Antiplatelet Agents
- Aspirin is used to prevent recurrent stroke, with a dosage of 75-325 mg/day, unless contraindicated by active bleeding or other conditions.
- Clopidogrel (Plavix®) is an alternative to aspirin, with a loading dose of 300 mg followed by 75 mg/day.
Anticoagulants for Cardioembolic Stroke
- Warfarin (Marevan) is indicated for hypercoagulable states and cardiac sources such as atrial fibrillation (AF) or intracardiac thrombi.
- Dabigatran (Pradaxa®) is used for persistent or paroxysmal nonvalvular AF and is more effective than warfarin.
- Rivaroxaban (Xarelto®) is a factor Xa inhibitor that reduces the risk of stroke and systemic embolism in nonvalvular AF, outperforming warfarin.
