Abstract
The present invention relates to microparticles comprising moxidectin and a biodegradable polymer, wherein the microparticles comprising moxidectin have a shape allowing a moxidectin drug to be uniformly distributed in spherical biodegradable polymer particles, and the average particle diameter of the microparticles is 80-130 μm. The present invention relates to: extended release microparticles capable of continuously maintaining a heartworm disease prevention effect for 3 months to 6 months by administering microparticles comprising moxidectin; and a preparation method therefor. In addition, the present invention is prepared such that the average diameters of the particles have a predetermined micrometer size, and thus reduces a foreign body sensation and pain during administration into an animal through injection, thereby enabling administration through injection to be facilitated.
