Abstract: Disclosed herein a pharmaceutical composition comprising aprepitant a pharmaceutically acceptable salt thereof; at least one hydrocarbon derivative selected from among a fatty acid of 14 to 18 carbon atoms, and a fatty alcohol of 14 to 18 carbon atoms; and at least one selected from among polyoxyethyelene-type nonionic surfactant, sucrose fatty acid ester, and Macrogol 15 hydroxystearate. The pharmaceutical composition of the present disclosure can release aprepitant or a pharmaceutically acceptable salt thereof to effectively exert the pharmaceutical efficacy, and can be dissolved in a fasted state simulated gastrointestinal fluid so that it can be useful for study on the in vivo pharmacokinetic behavior of aprepitant.

Abstract: The present invention relates to a method for manufacturing nano-scale particles of an active material. More particularly, the present invention relates to a method which uniformly mixes a surfactant having an HLB value of 8 or more and a melting point or glass transition temperature of 80° C. or lower and an active material, and mills the mixture using a roller mill, to thereby prepare nanoparticle powder from the active material.

Abstract: The present invention relates to a method for preparing nano-particles, and more particularly, to a method for preparing nano-particles containing active materials in a simple and highly efficient manner through a grinding process.

Abstract: The present invention relates to a method for preparing nanoscale or amorphous particles using solid fat as a solvent. According to the present invention, nanoscale or amorphous particles of active ingredients are prepared by using fat as a solvent, wherein the fat is in solid phase at room temperature. The nanoscale or amorphous particles of active ingredients can be advantageously used in medicine, cosmetics, functional foods or the like.
