MICROPARTICLES, PROCESSES FOR THEIR PREPARATION AND THEIR USE FOR THE PREPARATION OF MEDICAMENTS

摘要

Microparticles in the form of particles of a coagulum of an aqueous poly(meth)acrylate dispersion containing one or more useful substances which are slightly soluble or insoluble in water can be prepared by preparing a suspension of one or more useful substances which are slightly soluble or insoluble in an aqueous medium, in particular pharmaceutical active substances, in the aqueous phase of an aqueous poly(meth)acrylate dispersion and carrying out controlled coagulation of the poly(meth)acrylate particles of the dispersion, preferably by adding a solution of a strong electrolyte.
