摘要:
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 physiochemical 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 delievered by DPI when SAE-CD is used as a carrier.
摘要:
An inhalable formulation comprising 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.
摘要:
A process and equipment assembly for reacting a substituent precursor with a cyclodextrin starting material to provide a raw product comprising a cyclodextrin derivative and 1% or less of an initial amount of the substituent precursor is provided. The process of the present invention provides cyclodextrin derivatives in substantially shorter time and with fewer side products than previous processes that utilize substantially the same starting materials.
摘要:
The present invention related to low-chloride alkylated cyclodextrin compositions, along with processes for preparing and using the same. The processes of the present invention provide alkylated cyclodextrins with low levels of drug-degrading agents and chloride.
摘要:
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 SAE-CD. In particular, the SAE-CD composition possesses an advantageous physiochemical 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.
