Dual Antiplatelet Therapy in Secondary Prevention of Ischemic Stroke: A Ghost from the Past or a New Frontier?

Year: 2010

Type: article

Abstract: With majority of ischemic strokes attributable to atherothrombosis and many being predictable after transient ischemic attacks (TIA), the role of early secondary prevention with antiplatelet agents is under renewed investigation. Prior major clinical trials of various secondary stroke prevention regimens pointed to a greater efficacy of dual antiplatelet agents if initiated early from symptom onset. This paper examines data and rationale behind dual antiplatelet regimens across the completed clinical trials. The safety of dual antiplatelets approach is of concern, but it could be outweighed, at least in early management, by a greater reduction in recurrence of ischemic events since this risk is "front loaded" after minor stroke or TIA. Aspirin monotherapy, though considered standard of care, is compared to aspirin-extended release dipiridamole and its combination with clopidogrel in early-phase completed and efficacy-phase ongoing clinical trials.
