Arch Intern Med:他汀类药物副作用新添“成员”——疲劳

2012-06-19 Beyond 生物谷

近来许多研究报告表明,他汀类药物可能会引起一些人疲劳,近日完成的一项随机试验为这一观点提供了确凿证据。 相关研究论文发表在Archives of Internal Medicine杂志上,研究募集了0岁以上的1016名健康男性和女性,这些参试者体内血液中低密度脂蛋白水平或“坏”胆固醇水平从每分升115到190毫克不等。三分之一的参试者每天给予20毫克的辛伐他汀,三分之一参试者给予40毫克的普

近来许多研究报告表明,他汀类药物可能会引起一些人疲劳,近日完成的一项随机试验为这一观点提供了确凿证据。

相关研究论文发表在Archives of Internal Medicine杂志上,研究募集了0岁以上的1016名健康男性和女性,这些参试者体内血液中低密度脂蛋白水平或“坏”胆固醇水平从每分升115到190毫克不等。三分之一的参试者每天给予20毫克的辛伐他汀,三分之一参试者给予40毫克的普伐他汀,其余参试者给予安慰剂,三组给药共维持6个月。之后研究人员评价参试者“能量”和“疲劳与消耗”情况,结果各项参数分布在5点和10点之间。

研究人员发现低密度脂蛋白水平的人各项参数明显下降,但作为一个群体,两个他汀类药物组的参试者各各项参数均显着高于安慰剂组,即出现疲劳的可能性增加。

圣迭戈加利福尼亚大学的医学副教授Beatrice Golomb说,他汀类药物的副作用并不少见,这项研究证实了其最新的一项副作用。

Effects of Statins on Energy and Fatigue With Exertion: Results From a Randomized Controlled Trial

Beatrice A. Golomb, MD, PhD; Marcella A. Evans, BS; Joel E. Dimsdale, MD; Halbert L. White, PhD

No drug is without adverse effect potential, and fatigue and exertional intolerance are adverse effects reported by patients receiving statins.1 - 2 Little direct information is available regarding the typical or average impact of statins on energy or exertional fatigue.

Although many observational reports have cited fatigue and exertional fatigue with statin use, to our knowledge, no randomized trials have addressed this issue to date. Energy and exertional fatigue were measured as tertiary and/or exploratory outcomes in the University of California, San Diego (UCSD) Statin Study, which aimed to examine a range of noncardiac outcomes.3 We capitalized on these data to evaluate whether moderate-dose statins affected energy and exertional fatigue in a broadly sampled primary prevention population.
