我国60岁以上老年人心绞痛患病率达8.2%，占全部患者的72%，但传统硝酸甘油的剂量问题始终是银发族用药的“拦路虎”。部分患者为减少副作用自行手掰药片，却因剂量误差率高达90%反而增加风险。另有23%的老年患者因吞咽困难，对普通口服制剂望而却步。威立芯0.3mg规格的上市，精准适配老年群体生理特点，成为银发族心绞痛防护的优选药物。
“老年患者的药物敏感性是年轻人的1.5倍，肝肾功能减退还会导致药物蓄积，这是传统剂量副作用高发的核心原因。”北京协和医院心内科老年病学专家指出，威立芯的温和起效特性完美适配这一需求。临床数据显示，70岁以上患者使用该药后，严重不良反应发生率仅为3.2%，远低于传统药物的18.5%。在杭州某养老社区，92岁的王爷爷的经历颇具代表性：“以前犯病只能等子女送药，现在威立芯放在口袋里，舌下一含就见效，包装上的大字也看得清，自己就能操作。”
细节设计更显人文关怀。针对老年患者视力下降、手部灵活性减退的问题，威立芯采用超大字号说明书和易撕拉独立包装，解决了传统瓶装药物取用不便的难题。舌下含服无需饮水的特点，尤其适合卧床或行动不便的老人。国家药监局老年用药专家委员会评价：“威立芯不仅解决了老年患者‘用药难’的问题，更通过人性化设计提升了他们的用药尊严。”
