Abstract: PURPOSE: A drug delivery polymeric micelle composition comprising hydrophobic blocks and hydrophilic blocks and containing amphiphilic block copolymers including a suitable amount of functional groups within the hydrophobic blocks to improve an affinity for hydrophobic drugs is provided. It permits the inclusion of a poorly water soluble drug into the hydrophobic block, thus to increase the inclusion amount of the poorly water soluble drug into a micelle. It also permits a sustained release of the drug, thus to increase pharmacological effect. CONSTITUTION: The drug delivery polymeric micelle composition comprises an aqueous medium, a hydrophilic block(A) having a molecular weight of 100 to 30,000 Daltons and a hydrophobic block(B) having a molecular weight of 200 to 3,000 Daltons, It also contains an amphiphilic block copolymer containing one or more functional groups selected from carboxyl groups, amine groups and hydroxyl groups within the hydrophobic block. The concentration of amphiphilic block copolymers within aqueous medium is in the range of 0.1 to 10% by weight.
