目的:评价苯佐卡因含片对口腔溃疡、急性咽喉炎引起的疼痛的临床疗效和安全性。方法:采用多中心、随机、双盲、对照基质平行对照试验。口腔溃疡病例数60对,咽喉炎病例数40对,观察疼痛指数及镇痛疗效。采用X2,t检验或非参数统计方法。结果:试验组用药第1d、第2d能有效减轻疼痛,用药第1d镇痛维持时间长,与对照组相比有统计学意义(p<0.05),两组不良反应发生率无统计学意义(p=0.444)。结论:苯佐卡因含片能有效缓解和消除口腔溃疡、急性咽喉炎引起的疼痛,且安全性好。
Objective: To evaluate the clinical efficacy and safety of benzocaine lozenge in the treatment of oral ulcer and acute pharyngitis-induced pain. METHODS: A multicenter, randomized, double-blind, controlled-matrix parallel controlled trial was used. 60 cases of oral ulcer cases, the number of cases of pharyngitis 40 pairs of pain index and analgesic efficacy. Using X2, t test or non-parametric statistical methods. Results: The pain relief was relieved on the first day and the second day after treatment in the experimental group. The analgesic maintenance was longer on the first day than the control group (p <0.05), and the incidence of adverse reactions in the two groups was not statistically significant p = 0.444). Conclusion: Benzocaine lozenges can effectively relieve and eliminate the pain caused by oral ulcer and acute pharyngitis, and have good safety.
