Compositions are provided comprising a lipophilic active compound, e.g., a human or veterinary drug or a nutraceutical, interwoven with a polymeric matrix formed by two or more polymers, wherein one of the polymers is an amphiphilic polymer and the other polymer is either an amphiphilic polymer with a different hydrophobic-hydrophilic balance or a hydrophilic polymer, and the active lipophilic compound has modified physicochemical properties. The composition forms colloidal nanodispersion upon contact with aqueous media.
L'invention concerne des compositions comprenant un composé actif lipophile, par exemple un médicament à usage humain ou vétérinaire ou un nutraceutique, entrelacé avec une matrice polymérique formée par deux ou plus de deux polymères, l'un des polymères étant un polymère amphiphile et l'autre polymère étant soit un polymère amphiphile ayant une balance hydophobe-hydrophile différente soit un polymère hydrophile et le composé actif lipophile ayant des propriétés physicochimiques modifiées. La composition forme une nanodispersion colloïdale lors du contact avec des milieux aqueux.
