A randomized, double-blind, crossover trial was designed to compare the acute
effects of Combivent and salbutamol on spirometric parameters in patients with
moderate to severe asthma. Nineteen patients with a mean baseline forced expiratory
volume in 1 sec. (FEV]) less than 65% predicted, were randomized on two separate
days to receive two puffs of salbutamol (200 µg) or two puffs of Combivent (200 µg
salbutamol plus 40 µg of ipratropium bromide) by metered dose inhalers. On study
days using spirometry, FEV!, forced vital capacity (FVC), maximal mid-expiratory
flow rate (MMEF) and peak: expiratory flow rates (PEFR) were measured at baseline
and at 15, 60 and 180 minutes after drug administration. Blood pressure and pulse rate
were also determined before and 3 hours post drug inhalation.
The results of this study show that Combivent produces significantly greater
improvement compared to salbutamol in all four spirometric parameters at 15, 60,
and 180 minutes after drug treatment. The greatest differences between the
bronchodilating effects of the two re!imens were observed at 180 minutes after drug
inhalation. There were no clinically significant changes in heart rate or blood
pressure.
It may therefore be concluded that in patients with moderate to severe asthma,
Combivent provides better bronchodilation than salbutamo1 alone at clinically
relevant doses without increasing side-effects
