ABSTRACT:
An anti-inflammatory agent containing microparticle composition prepared by a process, comprising (a) dissolving or dispersing an anti-inflammatory agent in a solvent and dissolving a biocompatible and biodegradable wall forming material in said solvent; (b) dispersing said solvent containing said anti-inflammatory agent and wall forming material in a continuous phase processing medium; (c) evaporating a portion of said solvent from said dispersion of step (b), thereby forming microparticles containing said anti-inflammatory agent in the suspension; and (d) extracting the remainder of the solvent from said microcapsules.
