Abstract

L'invention concerne un émulsion grasse destiné à solubiliser ou disperser au moins un ingrédient actif sélectionné parmi paclitaxel ou docetaxcel, ledit émulsion graisse comportant un ingrédient huileuse, un émulsifiant et un stabilisateur, par exemple, le phosphatidylglycérol, sélectionné parmi les phospholipides, dérivés de phospholipides, et acides gras. L'invention concerne en outre un procédé pour obtenir un émulsion grasse contenant l'ingrédient actif à l'état d'une dispersion ou une solution, une précipitation de cristaux dudit ingrédient actif étant évitée. D'après ce procédé ledit émulsion est obtenu à partir de l'émulsion grasse.
