    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.

    Abstract: A method of preserving formulations is provided. The method includes the step of including a derivatized cyclodextrin in a formulation capable of sustaining microbial growth. One embodiment of the formulation employs a sulfoalkyl ether cyclodextrin as a preservative and optionally as a solubilizing and complexing agent. A suitable cyclodextrin is the CAPTISOL" brand cyclodextrin (sulfobutyl ether R-cyclodextrin). Whether or not the formulation includes a conventional preservative, the formulation will remain preserved for at least a minimum predetermined period. Specific embodiments of the invention include a carrier, a derivatized cyclodextrin and optionally one or more active agents, one or more water activity-reducing agents, and/or one or more complexation-enhancing agents. The derivatized cyclodextrin reduces the water activity of the formulation. A liquid formulation can be lyophilized or otherwise dried to yield a solid formulation that is optionally reconstitutable.
