Abstract:
The present invention relates to nanocomposites for the controlled delivery of active ingredients into the central nervous system. The nanocomposite according to the present invention comprises a biocompatible core part comprising biodegradable material, and polyelectrolytes able to form a electrostatic van der Waals interactions with the material of the core part. The core part of the nanocomposite is able to bind various pharmaceutical agents. The present invention also relates to a process for the preparation of the nanocomposite according to the present invention and to the use of the nanocomposite according to the present invention.

Claim (Index 6):
Process for the preparation of the nanocomposite as claimed in  claim 1 , characterized in that the following steps are performed:\n a) the polymer constituting the core-part is prepared in native conformation, with a diameter of 5-10 nm; b) a reversible interaction is formed between the core-polymer and the active ingredient in an aqueous media or in an appropriate buffer; c) the polyelectrolyte constituting the shell-part is added to the core as prepared in step b), comprising the polymer and active ingredient; wherein the preparation of the nanocomposite takes place within physiological environment, at pH between 6.5 and 7.5.
