  • Patent number: 10246524
    Abstract: A method for preparing sulfobutyl ether-?-cyclodextrin. ?-cyclodextrin and 1,4-sulfobutyrolactone are used as raw materials, and a proper amount of an organic solvent is introduced into an alkaline aqueous solution, so that the solubility of the 1,4-sulfobutyrolactone is increased, and the synthesis yield of the sulfobutyl ether-?-cyclodextrin is improved. Operations including ultrasonic dialysis, active carbon decoloration, freeze-drying and so on are performed on the obtained product solution, so as to obtain a powder product of the sulfobutyl ether-beta-cyclodextrin.

  • Patent number: 10117940
    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: 8975240
    Abstract: Peritoneal dialysis solutions including a glucose polymer and methods of using the dialysis solutions are disclosed herein. In a general embodiment, the peritoneal dialysis solution includes a glucose polymer in an amount to provide an increased ultrafiltration fluid volume for a given amount of carbohydrate absorbed compared to conventional dialysis solutions containing icodextrin as the active pharmaceutical ingredient. The increased ultrafiltration fluid volume for a given amount of carbohydrate absorbed is obtained by providing specific combinations of weight-average molecular weight, polydispersity index and concentration of the glucose polymer in the dialysis solution.
