[Comparative studies on pirbuterol, salbutamol and a placebo administered as an aerosol in asthmatic patients]

Abstract

In a single blind cross-over study 12 patients with asthma received in randomised order aerosols of pirbuterol 400 micrograms, salbutamol 200 micrograms or placebo. Only 9 patients met the criteria and were taken into account for the statistical analysis, namely a stable reversible broncho-obstruction. Pirbuterol and salbutamol did induce a considerable bronchodilation. Both drugs had a similar activity and few side effects.
