Inspiratory flow profiles through a novel dry powder inhaler (DPI) (Clickhaler; Innovata Biomed Ltd, St. Albans, UK) were recorded in 17 pediatric patients (aged 7-16 years) with stable mild to moderate asthma. Most patients (n = 14) could generate high peak inspiratory flows (PIFs) (> 60 L/min) and high flows early in the flow profile.

Design: Randomized, double-blind, placebo-controlled comparison of the bronchodilator response to albuterol DPI (200 microg) at inspiratory flow rates of approximately 15, 30, and 60 L/min in patients with stable asthma with demonstrated reversibility to albuterol.
