阿司匹林,您吃对了吗?

2017-09-06 15:11:45   中国青年网

提起阿司匹林,相信大家都不陌生,作为一种年过百岁的老药,至今仍然是预防和治疗多种疾病的首选药物之一,也是许多中老年人家中常备药。作为预防类药品,不少老年患者都有这样的疑问,阿司匹林我究竟需不需要吃,怎么吃,吃多少?本期,我们请首都医科大学附属北京朝阳医院药事部药师侯珂露讲讲阿司匹林的那些事儿。

无适应症

自行预防用药不可取

阿司匹林是中老年人的常用药,许多患者只知道吃了阿司匹林能“通血管”,却并不清楚它究竟是否适合自己。阿司匹林是抗血小板药,临床上主要用于冠心病、心肌梗死、脑卒中等疾病的预防和治疗,部分患者如冠脉支架植入术后等还需要与其他抗血小板药物联合治疗。对于具有心脑血管疾病高危因素(如高龄、吸烟、高血压、糖尿病、血脂异常等),或已发生过上述疾病的患者,需要服用阿司匹林进行一级或二级预防。大剂量阿司匹林则具有解热镇痛的作用。但是服用阿司匹林需要在医生指导下进行,无适应症、自行“预防用药”不可取!

服用前

仔细核对处方、药品规格

大多数患者服用阿司匹林都是“每天1片”。根据目前国内外指南共识的推荐,阿司匹林用于心脑血管疾病防治的一般剂量是每天75~100毫克,由于基因多态性、病理因素等影响,少数患者具有“阿司匹林抵抗”现象,使用常规剂量的阿司匹林无法达到理想的抑制血小板聚集效果,导致复发性的心脑血管事件。

通常我们所说的“每天1片”阿司匹林,是指目前最常用的100毫克/片的制剂规格,市面上还有25毫克/片、40毫克/片、50毫克/片、75毫克/片等多种规格。在综合评估患者的治疗需求和出血风险后,医生为适宜用药的患者确定剂量,因此服用前要仔细核对处方和药品规格。

服药时间

需要与剂型相对应

目前对于早晨还是晚上服用阿司匹林尚无明确定论。最为广泛使用的阿司匹林肠溶片建议空腹时服用,由于进食时胃内pH值升高,导致肠溶制剂会提前在胃内溶解释放,再加上食物残渣也会磨坏药片外面包裹的肠溶包衣,从而刺激、损伤胃肠道。而普通片则建议餐后服用,达到减少胃肠刺激的作用。此外,阿司匹林的泡腾片制剂主要用于解热镇痛,一般不用做长期的心血管事件预防。服药时间需要与剂型对应好,才能达到减少胃肠道损伤的目的。

服药禁忌

避免消化道出血

人们在服用阿司匹林期间最为担心的就是出血事件,其中以消化道出血最常见。服药期间出现呕吐物呈咖啡色、呕血、黑便、便血等症状及血小板、血红蛋白降低时需要特别警惕,并及时就医,既往曾有消化道出血或其他大出血的患者应慎用。

为了避免出血事件的发生,用药前需要医生权衡利弊决定是否用药及用药剂量,并严格遵医嘱用药;合并应用抗凝药物、解热镇痛类药物等可能会增加出血风险,用药前需要咨询医生或药师;在需要进行有创检查、手术、拔牙等操作前需告知医生并停药。
