[Inhalation therapy for bronchial asthma. A. Bronchodilator--beta 2-stimulant]

In the treatment of bronchial asthma, usefulness of beta 2-agonists aerosol inhalation are emphasized as well as sustained theophylline tablets recently. In this study, the effectiveness of procaterol metered dose inhalor on asthmatic patients were examined compared with procaterol tables. The effect of procaterol inhalor together with sustained-theophylline on Holter ECG were also examined. When procaterol was exchanged to inhalation from tablets, 41% of the patients were improved symptomatically. Procaterol inhalor had no effect on Holter ECG. Procaterol inhalation regularly was expected to be more useful in treating asthmatic patients than tablets.
