then , to determine whether the combination of cromolyn and a parasympathetic antagonist would similarly inhibit bronchoconstriction provoked by a different nonallergic stimulus , we measured the bronchomotor response of another group of asthmatic subjects to eucapnic hyperpnea of dry air at room temperature after treatment with cromolyn ( 200 mg ) , with ipratropium bromide ( 100 and 200 micrograms by metered-dose inhaler ) , and with cromolyn ( 200 mg ) and ipratropium bromide ( 200 micrograms ) given together .
