[Testing of lung function after theophylline inhalation (author's transl)].

In the pharmacological therapy of obstructive airway syndrome, a combined therapy with pharmaca of different effective principles often is necessary. In comparison to the systemical therapy equal effects with less substance are to be obtained by application of the medicament as an aerosol. We report about results of a clinical experimental study: In patients suffering from obstructive airway syndrome, body plethysmographic measures of the lung function were made after inhalation of theophylline as an aerosol, given in different doses. At the same time serum levels of theophylline were measured. We report about the results.
