Abstract

Aerosol dispensing devices and methods for using the same for administering aerosolized drugs to a subject are provided. Aspects of the aerosol dispensing device include an aerosol production unit configured to produce an aerosol from a liquid containing a pharmaceutically active drug, and a burst valve adapted to mechanically open in response to a subject's inhalation. The burst valve is configured to prevent airflow through the device until the subject's inhalation produces an operational pressure difference across the burst valve. In some embodiments, the operational pressure difference can be 15 cm H2O or less. Aspects of the invention can also include a heating element configured to evaporate water from aerosol droplets. The devices and methods of the invention find use in a variety of applications, such as in applications in which it is desired to administer an aerosolized drug to a subject.
