Inspiratory flow rates and volumes with the Aerolizer dry powder inhaler in asthmatic children and adults.

Objective: To assess the peak inspiratory flow rate (PIFR) and forced inspiratory vital capacity (FIVC) through the formoterol (Foradil*) Aerolizer* in patients with mild, moderate and severe asthma.

Research Design And Methods: PIFR and FIVC were assessed in 33 adults and 32 children using a spirometer alone (baseline), a spirometer with an adaptor, and a spirometer with an adaptor and the Aerolizer inhaler (placebo loaded).

Results: Of adult patients using the Aerolizer inhaler, 73% had PIFR values of >100 l/min and 91% had values of >60 l/min.
