偏头痛与血小板活性增加和脑血管缺血事件的发生有关。由于脑血管事件可能由血小板聚集引起,因此在偏头痛的治疗中进一步增强血小板活性是不可取的。有效预防偏头痛的β-肾上腺素受体阻滞剂包括普萘洛尔(非选择性)和美托洛尔(β 1-选择性),但β-受体亚型选择性如何影响偏头痛中的血小板行为尚不确定。在29例患者中,在普萘洛尔、美托洛尔和β 2选择性Li 32-468治疗1个月期间,治疗剂量获得了相当的临床反应。普萘洛尔增加血小板聚集和ATP释放,而美托洛尔减少,Li 32-468的作用可能与普萘洛尔有关。这些作用在很大程度上可以用已知的血小板β受体来解释,因此可以推广到其他有效的β受体阻滞剂。由于血小板活性的改变不能解释这些药物在偏头痛中的疗效,因此β受体阻滞剂对血小板的作用应被视为副作用。在偏头痛治疗中,如果疗效相同,应首选抑制血小板活性的β受体阻滞剂,这意味着应使用β 1选择性阻滞剂。
Migraine is associated with increased platelet activity and an incidence of cerebrovascular ischemic events. Because cerebrovascular events might result from platelet aggregation, enhancing platelet activity further in the treatment of migraine is not desirable. beta-Adrenoceptor blockers effective in migraine prophylaxis include propranolol (nonselective) and metoprolol (beta 1-selective), but it is uncertain how beta-receptor subtype selectivity might influence platelet behavior in migraine. In 29 patients, comparable clinical responses were obtained with therapeutic doses during 1 month of treatment with propranolol, metoprolol, and the beta 2-selective Li 32-468. Propranolol increased and metoprolol decreased platelet aggregation and ATP release, and the effect of Li 32-468 could be related to that of propranolol. These actions can be largely explained in terms of what is known of platelet beta-receptors and therefore can be generalized to other effective beta-blockers. Since altered platelet activity does not account for the efficacy of these agents in migraine, the actions of beta-blockers on platelets should be considered as side effects. Those beta-blockers inhibiting platelet activity should be preferred in migraine treatment, assuming equal efficacy, which implies the use of beta 1-selective blockers.
