Devices for delivering an active agent formulation to the lungs of a human patient

摘要

Devices for delivering an active agent formulation to the lungs of a human patient comprising a flow resistance modulator (100) adapted to change the flow resistance during delivery over one inhalation of an aerosolized active agent to the lungs of a human patient from a first flow resistance during an initial time period to a second flow resistance following the initial time period wherein the second flow resistance being less than the first flow resistance.
