Controlled release and taste masking compositions containing one or more
active principles inglobated in a three-component matrix structure, i.e.
a structure formed by successive amphiphilic, lipophilic or inert
matrices and finally inglobated or dispersed in hydrophilic matrices. The
use of a plurality of systems for the control of the dissolution of the
active ingredient modulates the dissolution rate of the active ingredient
in aqueous and/or biological fluids, thereby controlling the release
kinetics in the gastrointestinal tract.
