MEDICAMENT-CONTAINING HOLLOW PARTICLE

摘要

The present invention addresses problems such as of providing medicament-containing particles which have sufficient strength capable of enduring compression, coating, etc. and which are provided with a desired functionality, and a method for manufacturing the same. Provided are hollow particles which are composed of a shell and a hollow part, wherein the shell comprises a medicament and a polymer, and a hollow volume ratio with respect to the entire particle is 1% to 50%. Also provided is a method for manufacturing the hollow particles, the method comprising a step of granulating while spraying a solvent capable of dissolving a polymer onto a powdery mixture containing the medicament and the polymer.
