[Effect of an adrenergic-parasympatholytic aerosol combination on the respiratory function]

Abstract

The ventilatory and cardiocirculatory effects of salbutamol-ipratropium aerosol were examined in 27 subjects with bronchial obstruction. The activity of the association was compared with that of the two components at therapeutic doses. Then the effects and possible side-effects of the association were assessed at increasing doses. Lastly, the association was compared with its components. The association had the same latency time, but a more prolonged effect (still effective after 120'), when compared with salbutamol. It was decidedly superior to the parasympatholytic. No side-effects of any kind were observed.
