Abstract:
A liquid polymeric composition for controlled release of eprinomectin consisting essentially of:(a) 1 to 10% of eprinomectin; (b) 1 to 10% of a poly(lactide-co-glycolide) copolymer; wherein the weight ratio of the poly(lactide-co-glycolide) copolymer to the eprinomectin is 1:1 or less and the ratio of lactide:glycolide of the poly(lactide-co-glycolide) copolymer is from about 75:25 to about 65:35; and (c) at least one lipophilic solvent or a mixture of hydrophilic and lipophilic solvents, wherein the volume ratio of the hydrophilic and lipophilic solvents is from about 80:20 to about 5:95.
