title: Clinical pharmacology of a combination of bronchodilators.
abstract: 27 hospitalized patients (15 suffering from chronic bronchitis with evident bronchospasm and 12 with extrinsic asthma) were evaluated with regard to the bronchodilating effects of a Salbutamol + Ipratropium Bromide combination administered by aerosol. For comparison, the bronchial spasmolytic effectiveness of both drugs administered separately at therapeutic doses was also evaluated. Subsequently, the activity of increasing doses of the combination was studied, with particular regard to possible side-effects. The pharmacological combination studied exerted a strong bronchodilating activity, independently of dose increase, both in asthmatic and in bronchitic patients. No side-effects were observed.
