title: Combined treatment with ipratropium bromide and beta-2-adrenoceptor agonists in childhood asthma.
abstract: The effect of adding ipratropium bromide to treatment with beta-2-adrenoceptor agonists was studied in 13 asthmatic children in a double-blind cross-over trial. In the acute phase of the study inhalation of salbutamol 0.1 mg/kg followed by inhalation of 0.25 mg of ipratropium bromide was found to improve pulmonary function variables to a significantly greater extent than salbutamol followed by placebo. The combined therapy also provided significantly better protection than salbutamol plus placebo against exercise-induced asthma. Maintenance treatment with ipratropium bromide (two inhalations four times daily, 20 micrograms per inhalation) in combination with oral terbutaline and aerosolized salbutamol did not alleviate asthmatic symptoms or pulmonary function variables to a degree beyond that achieved with the beta-stimulants alone. There were no side effects associated with the ipratropium bromide treatment. These data suggest that higher doses of ipratropium bromide than are presently used should be tested for maintenance treatment of chronic asthma.
