FIELD: medicine, pharmaceutics.
SUBSTANCE: claimed invention relates to chemical-pharmaceutical industry and represents composition of polymeric micelle, suitable for encapsulation and suitable release of medications, which contains block-copolymers, assembled radially and have hydrophobic segment, directed inside, and hydrophilic segment, directed outside, and as block-copolymer it contains block-copolymer, which has affinity to HDL, which contains hydrophobic segment of polymeric chain, formed from hydrophobic amino acid derivative, obtained as a result of introduction of sterol residue into side chain of amino acid, and block-copolymer, which has affinity to lipoprotein, except HDL, which contains hydrophobic segment of polymeric chain, formed from hydrophobic amino acid derivative, obtained as a result of introduction of hydrophobic group, which has linear or branched structure, into side chain of amino acid.
EFFECT: invention ensures stable encapsulation of large-sized medications and their suitable release.
