[Comparative study of the bronchodilating action of fenoterol and ipratropium bromide administered by aerosols in acute attacks of asthma].

Eighteen patients hospitalised with acute bronchial asthma are examined. Nine were given aerosol treatment with an ipratropium bromide solution and 45 minutes later with a phenoterol solution. The remaining 9 were given the same treatment in reverse order. The results obtained showed that phenoterol has a stronger bronchodilatory activity than ipratropium bromide, especially when administered after the anticholinergic product.
