POLYMERIC MICELLE PHARMACEUTICAL COMPOSITION

摘要

A polymer micelle pharmaceutical composition is provided and includes: a block copolymer unit ± having a hydrophilic polymer chain segment and a hydrophobic polymer chain segment; and a block copolymer unit ² having a hydrophilic polymer chain segment and a hydrophobic polymer chain segment, wherein: the block copolymer unit ± and the block copolymer unit ² are radially arranged in the state in which the hydrophilic polymer chain segments are directed outward and the hydrophobic polymer chain segments are directed inward; and the hydrophobic polymer chain segment of the block copolymer unit ± is constituted of repeating units having side chains , at least one of the side chains having a hydrophilic group.
