  • Patent number: 11464862
    Abstract: An inhalable dry powder formulation containing SAE-CD and an active agent is provided. The formulation is adapted for administration by DPI. The SAE-CD serves as a carrier rather than as an absorption enhancer. The average particle size of the SAE-CD is large enough to preclude (for the most part) pulmonary deposition thereof. Following release from the DPI device, the SAE-CD-containing particles dissociate from the active agent-containing particles in the buccal cavity or throat, after which the active agent-containing particles continue deeper into the respiratory tract. The physicochemical and morphological properties of the SAE-CD are easily modified to permit optimization of active agent and carrier interactions. Drugs having a positive, neutral or negative electrostatic charge can be delivered by DPI when SAE-CD is used as a carrier.

  • Patent number: 10799599
    Abstract: An inhalable formulation containing SAE-CD and corticosteroid is provided. The formulation is adapted for administration to a subject by nebulization with any known nebulizer. The formulation can be included in a kit. The formulation is administered as an aqueous solution, however, it can be stored as a dry powder, ready-to-use solution, or concentrated composition. The formulation is employed in an improved nebulization system for administering corticosteroid by inhalation. SAE-CD present in the formulation significantly enhances the chemical stability of budesonide. A method of administering the formulation by inhalation is provided. The formulation can also be administered by conventional nasal delivery apparatus.

  • Patent number: 10703826
    Abstract: A particulate SAE-CD composition is provided. The SAE-CD composition has an advantageous combination of physical properties not found in known solid forms of SAECD. In particular, the SAE-CD composition possesses an advantageous physicochemical and morphological property profile such that it can be tailored to particular uses. The SAE-CD composition of the invention has improved flow and dissolution performance as compared to known compositions of SAE-CD.
