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 ?m. 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.

Abstract: The present invention relates to: sustained-release microparticles capable of maintaining, for a long time, effects of preventing, treating or alleviating benign prostatic hyperplasia and prostate cancer and effects of preventing hair loss and promoting hair growth according to the administration of microparticles containing dutasteride; and a preparation method therefor, and according to the use of a method for administering the particles to a patient through an injection, a patient does not have to directly store or handle the microparticles, unlike an oral dosage form, and thus storage and handling are simple. In addition, drug effects are maintained for a long period of time of 1-3 months and, simultaneously, administration through injection can be facilitated since foreign body sensation and pain are reduced when being administered to a patient through injection because of the constant average diameter of the particles.

Abstract: In the present invention, two adjacent supply lines for supplying two immiscible fluids are spirally disposed on a substrate where microchannels for microsphere production based on a droplet-based highly controlled method for mass-production of microspheres (HCMMM) are formed, and microsphere forming parts each comprising microchannels are arranged between and along the two supply lines, whereby a much larger amount of microspheres can be produced. Further, the two supply lines are disposed in a spiral configuration, and the microsphere forming parts can be disposed by branching microchannels from the two supply lines on inner and outer sides of the spiral configuration, whereby the limited space on a wafer normally having a circular shape can be maximally used to form multiple microsphere forming parts.
