雙重抗血小板藥物之新希望?淺談THALES試驗

Dual Antiplatelet Therapy in Acute Stroke: A New Hope?

並列摘要


Since the positive results of CHANCE and POINT trials, early initiation of dual antiplatelet therapy comprised of clopidogrel and aspirin, administered for 10 to 21 days, has become a standard treatment protocol for patients with mild acute ischemic stroke or high risk transient ischemic attack. The recently published THALES trial demonstrated that combining ticagrelor, a direct acting platelet P2Y12 receptor antagonist, and aspirin for 30 days can also prevent at least 17% of early recurrent stroke in the similar patient group, but increase major bleeding risk up to four times compared with standard treatment. A ticagrelor-based dual antiplatelet therapy may provide an alternative option to those who are clopidogrel poor-respondent; nevertheless, the concern of higher bleeding risk may preclude its universal usage. Further clinical trials comparing clopidogrel-based and ticagrelor-based dual antiplatelet therapy may help clarifying direct evidence on which combination regimen is favored.
