Comparison of terbutaline via the Nebuhaler and salbutamol via the Volumatic: theory and practice.

The bronchodilating efficacy of terbutaline (250 micrograms.puff) inhaled via the Nebuhaler and salbutamol (100 micrograms.puff) inhaled via the Volumatic has been studied in 30 patients with reversible obstructive airways disease in a randomized crossover study. The salbutamol/Volumatic combination produced significantly greater bronchodilatation than terbutaline/Nebuhaler (one puff, p less than 0.001; eight puffs, p less than 0.01). The findings are discussed with particular reference to the theories of spacer action.
