PARTICLES, METHOD FOR PRODUCING PARTICLES, AND PHARMACEUTICAL COMPOSITION

Abstract

A method for producing particles is provided. The method includes: preparing a bioactive-substance-containing liquid that includes a bioactive substance and a solvent; discharging the bioactive-substance-containing liquid as droplets; and removing the solvent from the droplets to form particles, wherein a biological activity ratio represented by {(biological activity level B/biological activity level A)×100} is 80% or greater, where the biological activity level A is a biological activity level of the bioactive substance before the preparing the bioactive-substance-containing liquid, and the biological activity level B is a biological activity level of the bioactive substance after the preparing of the bioactive-substance-containing liquid.
