ABSTRACT:
Microparticles and a method for their production is described. The process of the present invention provides a simple, quick, and efficient one-pot process for the production of microparticles containing a non-water soluble active agent. The microparticles are preferably used for pharmaceutical applications and comprise at least 80 wt % microspheres.
