NOVEL FINE PARTICLE COATING (DRUG-CONTAINING HOLLOW PARTICLE AND METHOD FOR MANUFACTURING SAME)

Document Type and Number:

WIPO Patent Application WO/2019/130749

Kind Code:

A1

Abstract:

Provided is a method for manufacturing a particle coated with fine particles capable of coating. A method for manufacturing a particle coated with fine particles capable of coating, the manufacturing method characterized by including a step for adding fine particles capable of coating to an inner core including a polymer and a target component, and, while rolling the mixture, performing coating while spraying a solvent capable of dissolving the polymer, the particle coated with fine particles capable of coating being a target-component-containing hollow particle which is coated.
