A comparison between a combination of ipratropium bromide plus fenoterol in a single metered dose inhaler (Duovent) and salbutamol in asthma

Abstract

SummaryThe efficacy of a single metered dose inhaler containing a combination of fenoterol (100 ,ug/puff) and ipratropium bromide (40 ,ig/puff) has been assessed in 12 asthmatics. We conclude that the bronchodilator effect of 2 puffs of the combination inhaler was significantly greater than that achieved by 2 puffs of salbutamol (100,ug/puff).
