  • Publication number: 20100292268
    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.

  • Patent number: 7829114
    Abstract: A capsule containing an aqueous fill composition that comprises water, a derivatized cyclodextrin, such as sulfoalkyl ether cyclodextrin (SAE-CD) or hydroxypropyl cyclodextrin (HPCD), optionally one or more active agents and optionally one or more excipients is stabilized from degradation, erosion, swelling or dissolution of its shell during storage. The derivatized cyclodextrin is present in an amount sufficient to reduce, eliminate or inhibit degradation, erosion, swelling and/or dissolution of the shell by water present in the fill composition. Alternatively, the derivatized cyclodextrin and another shell-stabilizing material together stabilize the shell from degradation, erosion, swelling and/or dissolution by water present in the fill composition. The derivatized cyclodextrin can reduce the water activity of the fill composition.

  • Publication number: 20100093663
    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.
