LIPID CARRIER FOR DELIVERY OF BIOACTIVE SUBSTANCE AND PHARMACEUTICAL COMPOSITION

Abstract

The present invention provides a lipid carrier for delivering of a bioactive substance. The lipid carrier includes a lipid layer, a positive charged polymer and a surface active polymer. The positive charged polymer and the surface active polymer are respectively distributed on the lipid layer by non-covalent bonds. The present invention also provides a pharmaceutical composition. The present invention is advantageous for delivering bioactive substance efficiently.
