NOVEL EPRINOMECTIN INJECTABLE COMPOSITIONS

摘要

An improved injectable parasiticide composition for treating infections caused by ectoparasites and endoparasites, wherein the formulation comprises a solvent system comprising polyethylene glycol and optionally other excipients and a pharmaceutically acceptable solvent or mixture of solvents and co-solvents, said novel formulation being capable of improving the bioavailability and residence time of the parasiticide in the treated non human mammals. Preferred compositions according to the invention comprise parasiticides which are macrocyclic lactones having poor liphophilic properties, such as for example eprinomectin.
