Phospholipid-based powders for inhalation

摘要

Methods for inhalation are provided. The formulations for inhalation are engineered to be highly dispersible and provide rapid absorption of the active agent so delivered, as well as substantially independent emitted doses and lung deposition as functions of device resistance and inspiratory flow rates, respectively. The present invention also provides reductions in the flow rate dependence in lung deposition and improvements in patient reproducibility.
