The Characterisation of Inhalation Devices by an Inhalation Simulator: The Electronic Lung

Abstract
The Electronic Lung is an inhalation simulator designed for the characterisation of breath-actuated inhalation devices. It enables the in-vitro evaluation of devices under conditions that have been produced ln-vivo. Data generated on the Serevent* Diskhaler* inhaler have highlighted the reproducibility of particle size distribution of drug delivered from the device over a range of inhalation parameters.
