Abstract: The present invention is directed to pharmaceutical compositions comprising melphalan and a cyclodextrin derivative, and methods of making and using the same.
Abstract: SAE-CD compositions are provided, along with methods of making and using the same. The SAE-CD compositions comprise a sulfoalkyl ether cyclodextrin having an absorption of less than 0.5 A.U. due to a drug-degrading agent, as determined by UV/vis spectrophotometry at a wavelength of 245 nm to 270 nm for an aqueous solution containing 300 mg of the SAE-CD composition per mL of solution in a cell having a 1 cm path length.
Abstract: The present invention relates to compositions comprising fractionated alkylated cyclodextrin compositions having a single degree of substitution, and processes for preparing and using the same.

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.

Abstract: An aqueous composition of latanoprost and SAE-CD is provided. The composition possesses improved stability over otherwise similar compositions excluding SAE-CD. Methods of and systems for treating disease, disorders, conditions or symptoms of the eye that are therapeutically responsive to latanoprost are also provided.
Abstract: Cosmetic and dietary supplement compositions containing silymarin and sulfoalkyl ether cyclodextrin, particularly sulfobutyl ether cyclodextrin, are described. The compositions and methods are useful in reducing appearance of facial redness in rosacea-prone skin, rejuvenating skin, preventing skin aging, inhibiting oxidative stress in epidermal and dermal cells, increasing collagen production, reducing the likelihood of skin cancer, treating or reducing liver damage from a toxin, or treating a liver disease.

Abstract: 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.

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.

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.

Abstract: The present invention provides compositions containing clopidogrel, present as a free base or a pharmaceutically acceptable salt thereof, and sulfoalkyl ether cyclodextrin (SAE-CD). The compositions can be liquid, suspension or solid compositions. They can be adapted for oral, peroral or parenteral administration. The SAE-CD serves to aid in dissolution and stabilization of the clopidogrel in aqueous media. The stability of clopidogrel against hydrolytic degradation, thermal degradation, and photolytic degradation are improved. SAE-CD provides improved results over other cyclodextrin derivatives. The SAE-CD-containing composition of clopidogrel can be provided in liquid form, solid form or as a reconstitutable powder. Both ready-to-use and concentrated liquid compositions can be prepared. The liquid composition is optionally available as a clear solution.
