Patent ID: 7829114

Claim:
A capsule comprising: a water soluble, erodible, degradable and/or swellable shell; and an aqueous fill composition comprising one or more active agents, water in an amount of at least 10% to less than 50%, by weight, of the fill composition, and a water soluble cyclodextrin derivative in an amount of at least 50%, by weight, of the fill composition, wherein the capsule has a shelf-life of at least one week; wherein the fill composition has a water activity of less than 0.95±0.01, and wherein the water soluble cyclodextrin derivative is a sulfoalkyl ether cyclodextrin of formula 1: wherein: n is 4, 5 or 6; R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 and R 9 are each, independently, —O—or —O—(C 2 -C 6 alkylene)—SO 3 − , wherein at least one of R 1 , R 2 R 3 , R 4 , R 5 , R 6 , R 7 , R 8 and R 9 is independently —O—(C 2 -C 6 alkylene)—SO 3 − selected from the group consisting of: —O—(CH 2 ) m SO 3 − wherein m is 2 to 6, —OCH 2 CH 2 CH 2 SO 3 − , and —OCH 2 CH 2 CH 2 CH 2 SO 3 − ; and wherein S 1 ,S 2 ,S 3 ,S 4 , S 5 , S 6 , S 7 , S 8 , and S 9 are each, independently, a cation.
