Abstract

Dry powder aerosol generators and related methods are provided. The dry powder aerosol generator includes a dispersion chamber having an internal cavity therein capable of receiving a dry powdered drug. The dispersion chamber includes a dosing port defined therein that is in fluid communication with the internal cavity. A dosing chamber for receiving a test subject is attachable to the dosing port, such that, when an airflow is created within the internal cavity, any dry powdered drug contained therein may fluidize and travel into the dosing chamber to provide opportunity for inhalation of the dry powdered drug by a test subject contained within the dosing chamber.
