摘　　要：目的探讨美西律致口唇麻木不良事件的因果关系评价及可能的作用机制、影响因素,为制定针对性的防范措施提供依据。方法分析互联网(百度和今日头条)、数据库(万方数据、中国知网、维普网、PubMed)和世界卫生组织个案安全报告全球数据库(VigiBase)中美西律的口唇麻木不良事件,因果关系评价包括个例和案例系列。结果自建库/系统至2020年4月26日,美西律引起口唇麻木的不良事件报告共10例:其中互联网网络咨询3例、VigiBase 3例、数据库文献报道4例,因果关系评价(Naranjo评分)都支持因果关系。可能发生机制为美西律结构与利多卡因相似,有局部麻醉作用,从而导致口唇麻木;口唇麻木发生时间为服药后即刻至给药后5 d,停药可自行恢复,可能与服药方法有关。结论美西律致口唇麻木与其局部麻醉相关,所以口服制剂应与饮料或食物同服、不得嚼碎,以避免不良反应的发生。Objective To explore the causality,possible mechanism and influencing factors of such adverse events as oral and lip numbness associated with mexiletine so as to provide data for precautions.Methods Literature related to adverse events of oral and lip numbness caused by mexiletine were retrieved from such databases as Wanfang,CNKI,VIP,PubMed and VigiBase before being analyzed.The causality of single cases or a series of cases was explored.Results As of April 26,2020,there were 10 cases of oral and lip numbness associated with mexiletine:3 cases from online consultation,3 cases from VigiBase,and 4 cases from literature.Causal analysis by Naranjo criteria delivered a causality score that supported causality between mexiletine and adverse reactions.The possible mechanism was that mexiletine was structurally similar to lidocaine,so it had a local anesthetic effect,which could cause oral and lip numbness.The onset time of oral and lip numbness ranged from shortly after administration to 5 days after administration,but the patients recovered after withdrawal.Routes of administration might play a role.Conclusion Mexiletine can cause oral and lip numbness,which is related to the local anesthetic effect.Therefore,oral preparations should be taken as a whole along with beverages or foods rather than being chewed to prevent adverse reactions.
