  • Publication number: 20180303753
    Abstract: Disclosed are inhalation formulations of dry powders comprising particles and processes which yield particles to effectively bypass unwanted deposition in the mouth and throat. Embodiments of the invention are characterized by an inertial parameter which provide an in vitro total lung dose of greater than 80% of a nominal dose. Embodiments of formulations include neat formulations containing active agent only; formulations of active agent and buffer; and formulations comprising active agent, a glass-forming, and/or a shell-forming excipient. Also provided are methods for making the dry powder formulations. The powder formulations are useful for the treatment of diseases and conditions especially respiratory diseases and conditions.

  • Patent number: 9744318
    Abstract: A powder aerosolization apparatus comprises a housing comprising an outlet adapted to be inserted into a user's mouth and one or more bypass air openings. A receptacle support within the housing supports a receptacle containing a powder pharmaceutical formulation. A puncturing mechanism within the housing creates in the receptacle one or more inlet openings and one or more powder outflow openings, wherein the powder outflow openings have a total area of from 0.2 mm2 to 4.0 mm2. Upon a user's inhalation through the outlet, air flows through the one or more bypass air openings and through the receptacle to aerosolize the powder pharmaceutical formulation in the receptacle. In one version, the relative flow parameters between the flow through the one or more bypass openings and the one or more powder outflow openings are selected so that flow of aerosolized pharmaceutical formulation does not occur until a predetermined inhalation flow rate is achieved.
