Carbuterol tablets (2,0 mg) were compared with the tablets of fenoterol (2,5 mg) and hexoprenaline (1 mg). The three drugs were shown to be equally effective for a period of 4 hours, but carbuterol and fenoterol exerted a statistically significant bronchodilating action for 7 and 8 hours respectively, while the action of hexoprenaline lasted for 4 hours in the majority of patients. The aerosols of carbuterol (200 mg) and fenoterol (400 mg) appeared to be similar in inhibiting exercise-induced asthma, whereas hexoprenaline (200 mg) did not appear to be as effective.
将克仑特罗片（2.0毫克）与非诺特罗片（2.5毫克）和己双肾上腺素片（1毫克）进行了比较。结果表明，这三种药物在4小时内疗效相当，但克仑特罗和非诺特罗分别在7小时和8小时产生了具有统计学意义的支气管扩张作用，而在大多数患者中，己双肾上腺素的作用持续4小时。克仑特罗气雾剂（200毫克）和非诺特罗气雾剂（400毫克）在抑制运动诱发哮喘方面似乎相似，而己双肾上腺素气雾剂（200毫克）似乎效果不佳。
