A randomized, double-blind, placebo-controlled clinical trial has shown that treatment of the common cold with zinc gluconate lozenges resulted in a significant reduction in duration of symptoms of the cold. Patients received zinc-containing lozenges or placebo lozenges every 2 hours for the duration of cold symptoms. The median time to complete resolution of cold symptoms was 4.4 days in the zinc group compared with 7.6 days in the placebo group. The mechanism of action of zinc in treating the common cold remains unknown.
一项随机、双盲、安慰剂对照的临床试验表明,用葡萄糖酸锌含片治疗普通感冒可显著缩短感冒症状的持续时间。在感冒症状持续期间,患者每2小时服用含锌含片或安慰剂含片。锌组感冒症状完全缓解的中位时间为4.4天,而安慰剂组为7.6天。锌治疗普通感冒的作用机制尚不清楚。
