    摘要: The present invention provides a particulate pharmaceutical composition which has improved drug encapsulation stability and is suitable for a drug delivery system. The particulate pharmaceutical composition 1 contains: a plurality of block copolymer unit 2 arranged radially, each of which has a hydrophobic polymer-chain segment 2b, which is arranged radially inside, and a hydrophilic polymer-chain segment 2a, which is arranged radially outside; a drug 4, which includes a biomacromolecule; and a charged lipid 3, which has an electrical charge opposite to that of the drug 4; wherein the charged lipid 3 is being attracted to the hydrophobic polymer-chain segment 2b, and the drug 3 is positioned radially inside the hydrophobic polymer-chain segment 2b. The pharmaceutical composition 1 can effectively prevent the drug 4 from disengaging from the particle.

    摘要: The present invention provides a particulate composition containing: block copolymer units being arranged radially with hydrophobic polymer-chain segments radially inside and hydrophilic polymer-chain segments radially outside; and a charged lipid which carries a charge opposite to the charge of a drug to be encapsulated, the charged lipid being attracted to the hydrophobic polymer-chain segment. In this particulate composition, the drug is retained within the particle via electrostatic binding with the charged lipid, whereby the outer surface of the particle is prevented from being charged to attract a substance which has a charge opposite to that of the charged lipid.
