Beschreibung
Zusammenfassung:	Disclosed are compositions exhibiting a combination of immediate release and controlled release characteristics. The compositions comprise at least one poorly soluble active ingredient having a nanoparticulate particle size, at least one surface stabilizer adsorbed onto the surface of the nanoparticulate active agent particles, and at least one active ingredient having a microparticulate particle size. L'invention concerne des compositions combinant des caractéristiques de libération immédiate et de libération prolongée. Ces compositions comprennent au moins un principe actif peu soluble dont la taille des particules est de dimension nanométrique, au moins un agent de stabilisation de surface adsorbé sur la surface des particules de dimension nanométrique du principe actif, et au moins un principe actif dont la taille des particules est de dimension micrométrique.
