A comparison of the effects of salbutamol, fenoterol, and placebo aerosols on airway resistance in asthmatics

Abstract

The reduction in airways resistance, assessed by measurements of forced expiratory volume in one second, vital capacity and peak expiratory flow rate was estimated before and after inhalation of fenotei, salbutamol or placebo aerosols in nine asthmatic subjects. This study showed that fenoterol is significantly better than salbutamol in terms of magnitude and duration of response.
