Prevention of ischaemic stroke--antiplatelets.
Aspirin is the treatment of first choice for long-term secondary prevention of vascular events in patients with confirmed non-cardioembolic ischaemic stroke or TIA. However, there is no good evidence that it is of benefit in primary stroke prevention. If aspirin is contra-indicated, dipyridamole monotherapy is a relatively cheap, but slightly less effective, alternative. Aspirin and dipyridamole have an additive effect in secondary stroke prevention, but there is a high incidence of side effects and subsequent discontinuation of treatment with combination therapy. It is reasonable to consider clopidogrel for secondary prevention of vascular events in patients with ischaemic stroke who are intolerant of aspirin or dipyridamole, or who have a history of ischaemic heart disease. However, its cost is considerable. Over the next decade, oral antiplatelet agents directed against specific platelet receptors, or a combination of antiplatelet drugs inhibiting different aspects of platelet function, may improve secondary prevention of stroke.
