The efficacy and adverse effects of ketotifen 1 mg twice daily and 2 mg twice daily were compared with placebo in 50 patients with atopic asthma in a multicentre, double-blind study. Ketotifen in the higher dosage caused a slight reduction in salbutamol usage and a modest improvement in breathing in patients not already receiving inhaled corticosteroids. The drug was ineffective in patients receiving inhaled corticosteroids. Drowsiness was a troublesome effect causing withdrawal from treatment or reduction of dosage in seven patients while receiving ketotifen compared with only three while receiving placebo.
在一项多中心、双盲研究中,对50例特应性哮喘患者比较了每日两次服用1毫克和每日两次服用2毫克酮替芬与安慰剂的疗效及不良反应。较高剂量的酮替芬使未接受吸入性糖皮质激素治疗的患者沙丁胺醇用量略有减少,呼吸功能有一定改善。该药物对接受吸入性糖皮质激素治疗的患者无效。嗜睡是一个麻烦的副作用,服用酮替芬时有7例患者因嗜睡而停药或减量,而服用安慰剂时只有3例。
