B
Feedback:
Epinephrine may be injected subcutaneously in an acute attack of bronchoconstriction, with therapeutic effects in 5 minutes that last 4 hours. It is considered the drug of choice for the treatment of acute bronchospasm. Ipratropium bromide has an onset of action of 15 minutes when inhaled with a duration of 3 to 4 hours. Cromolyn is not for use during acute times of bronchospasm but is used to help prevent bronchospasm. Ephedrine can be used in acute bronchospasm but epinephrine remains the drug of choice.
