title: [The bronchodilatory effect of fenoterol-HBr in comparison to the new beta2-bronchodilator (NAB 365, clenbuterol-HCl) (author's transl)].
abstract: The effect of 4-amino-alpha-[(tert.-butylamino)methyl]-3,5-dichlorobenzyl alcohol hydrochloride (clenbuterol-HCl NAB 365, Spiropent) in comparison to fenoterol HBr was tested in a doubleblind trial in 30 patients with asthma bronchiale. 3 times daily for 7 days 15 patients inhaled 24 microgram NAB 365 or 5 mg fenoterol HBr respectively. The bronchospasmolytical effect proved optimal as one day after inhalation both test groups showed a significant decrease of resistance in the respiratory system. A quantitative difference of efficacy between the tested bronchodilators did not materialize.
