Twenty-four inpatients affected by chronic cough completed a single-dose double-blind cross-over study of placebo, glaucine 30 mg and dextromethorphan 30 mg. The study was carried out using a balanced incomplete block design, each patient receiving two of the three experimental treatments. Objective evaluation of cough was ensured by means of a writing cough recorder. Coughs after dextromethorphan and glaucine were fewer than coughs after placebo: however only glaucine was significantly different from placebo in reducing coughs. Treatments were well tolerated: clinical results included a reduction in pulse rate after both dextromethorphan and glaucine , and a large number of patients reporting side effects after dextromethorphan administration.
24名慢性咳嗽住院患者完成了一项关于安慰剂、30毫克海葱素和30毫克右美沙芬的单剂量双盲交叉研究。该研究采用平衡不完全区组设计进行,每位患者接受三种实验治疗中的两种。通过书写式咳嗽记录仪确保对咳嗽进行客观评估。右美沙芬和海葱素后的咳嗽次数少于安慰剂后的咳嗽次数:然而,只有海葱素在减少咳嗽方面与安慰剂有显著差异。治疗耐受性良好:临床结果包括右美沙芬和海葱素后脉搏率降低,以及大量患者在服用右美沙芬后报告有副作用。
