目的 观察疏风解毒胶囊治疗急性咽炎风热证的临床疗效及安全性。方法 将120 例急性咽炎风热证患者随机分为治疗组及对照组，各60 例。治疗组口服疏风解毒胶囊4 粒/次、3 次/d，对照组服用清开灵软胶囊2 粒/次、3 次/d，疗程均为5 d。观察治疗前后咽痛、咽部黏膜充血程度及咽干、灼热等主次症的改善程度及积分变化。结果 治疗组痊愈35 例，总有效率96.67%；对照组痊愈29 例，总有效率86.67%，两组疗效比较差异有统计学意义（P <0.05）。咽痛主症VAS 评分，治疗组减（5.56±1.82）分，对照组减（3.00±2.27）分，两组相比差异有统计学意义（P <0.05）。不良反应发生率，治疗组为1.67%，对照组为3.33%。结论 疏风解毒胶囊对治疗急性咽炎风热证疗效确切，且不良反应少，可供临床推广应用。
