Clenbuterol is a beta 2-sympathomimetic bronchodilator. In a double-blind cross-over trial in 19 asthmatic patients with reversible airways obstruction, oral administration of both clenbuterol (40 microgram) and salbutamol (4 mg) caused significantly greater increased in peak expiratory flow rate (PEFR) than placebo, that of clenbuterol lasting longer. The patients' subjective assessment also suggested the relief of their symptoms by the active drugs. Side-effects were minimal.
克仑特罗是一种β2-拟交感神经支气管扩张剂。在一项针对19名患有可逆性气道阻塞的哮喘患者的双盲交叉试验中,口服克仑特罗(40微克)和沙丁胺醇(4毫克)均比安慰剂显著提高了呼气峰值流速(PEFR),且克仑特罗的作用持续时间更长。患者的主观评估也表明活性药物缓解了他们的症状。副作用极小。
