Inhaled atropine in asthma

R M Snow et al. Ann Allergy. 1979 May.

Abstract

Ten adult asthmatics inhaled atropine and isoproterenol to determine the site of action in the airways and relative effectiveness of the two drugs. The two agents were equal in their effect on lung volumes and airway resistance but isoproterenol produced significantly better flows. Atropine was shown to be an effective bronchodilator with a predominant site of action in large airways. The authors believe atropine and atropine derivatives deserve ongoing investigation, especially regarding potential side effects of retarding mucociliary clearance and the clinical significance of apparent failure to dilate small airways.
