title: Inspiratory flow rates through a novel dry powder inhaler (Clickhaler) in pediatric patients with asthma.
abstract: 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. These flows have been shown to be adequate to deaggregate and deliver micronized drug with this delivery system.
