Inhaled Fenoterol powder in asthma: a long term study

A study was designed to assess the long term efficacy of Fenoterol powder in asthmatic children. The design included an initial assessment period and a further evaluation after six months, in which Fenoterol or placebo treatments were administered on consecutive days. Objective measurements were obtained from PEFR and FEV1. A diary record was kept to monitor compliance and side effects. A minimum dose of 200 mcg Fenoterol powder was prescribed three times per day. The bronchodilator action of Fenoterol was sustained after a period of six months, in the absence of significant side effects.
