Galenical system for active transport, method for preparation and use
First Claim
1. A galenic system in the form of strictly hydrophobic solid lipidic particles comprising at least one hydrophobic wax;
- at least one non-neutralized fatty acid; and
an active constituent that has been eliminated from the surface of the lipidic particles by washing said particles with a washing mixture comprising ethanol, wherein the particles have a size between 0.5 microns and 1,500 microns, contain no water, surfactants, emulsifying agents, or traces of solvents, and have a melting temperature between 15°

Abstract
The invention relates to a novel galenical system for taste masking, protecting an active substance, in particular in an acid medium, modulating releasing properties, masking mucous irritability and toxicity of certain active substances, for preparing aqueous forms which have a masked taste, are stable and pH independent. Said invention also relates, in particular to a galenical system which is embodied in the form of lipidic solid particles and strictly hydrophobic and devoid of water, surface active agents, emulsifiers, solvent traces and which is characterized in that it comprises at least one type of hydrophobic wax and at least one type of fatty non-neutralized acid.
