摘要：

[Problem] To provide a physiologically active peptide-loaded stable composition for injection into living bodies.[Solution] A composition containing a triblock copolymer represented by formula (I), a polyanionic polymer and a physiologically active peptide:CNR-PEG-CNR  (I)in the formula,CNR moieties are each independently a polymer segment containing a repeating unit that contains, as a part of a pendant group, a cyclic nitroxide radical bonded to a main polymer chain via a linking group that contains at least one amino group, andPEG is a segment that contains poly(ethylene glycol).
