The effects of ipratropium bromide and fenoterol nebulizer solutions in children with asthma.
The effects of nebulized solutions of ipratropium bromide and fenoterol combined were compared with the response to either preparation alone in single dose and longer-term administration in children who had asthma. The combination produced a slightly greater response than either alone, especially in peak expiratory flow. Over a 1-month period, there were no significant differences in symptom scores or lung function parameters between the combination of ipratropium bromide and fenoterol and fenoterol alone in a group of children who had asthma. It is possible that the addition of ipratropium bromide to a sympathomimetic drug may be useful in a subgroup of asthmatics, particularly if there is a considerable large airway contribution to bronchial narrowing.
