Patent ID: 7326426

Claim:
A composition comprising: an effective amount of a bioactive agent, and a polymer comprising the reaction product of at least one polybasic acid selected from the group consisting of succinic acid, succinic anhydride, malic acid, tartaric acid, citric acid, diglycolic acid and diglycolic anhydride and at least one monoglyceride selected from the group consisting of monostearyl glycerol, monopalmitoyl glycerol, monomyrisitol glycerol, monocaproyl glycerol, monodecanoyl glycerol, monolauryl glycerol, monolinoleoyl glycerol and monooleoyl glycerol, said polymer comprising an aliphatic polyester backbone having pendant fatty acid ester groups and said polymer having a melting point less than about 25° C., as determined by differential scanning calorimetry.
