MEANS FOR DELIVERY OF ACTIVE AGENT Russian patent published in 2018 - IPC A61K9/127 A61K31/722 A61K47/36

Abstract RU 2669354 C1

FIELD: pharmaceuticals.

SUBSTANCE: invention relates to pharmaceutical industry and biotechnology, namely to means for delivery of an active agent comprising a liposomal suspension complex with a chitosan conjugate which is a compound of formula (C₆O₄H₉NH₂)_m(C₆O₄H₉NHX)_n, wherein the substituent on the amino group X is a monomethoxy-PEG succinate, m and n are the number of units in the molecule, the m/n ratio being 6 to 19, and chitosan is used with a molecular weight of 15,000 to 120,000 Da, while liposomes are associated with the chitosan conjugate non-covalently.

EFFECT: invention provides improvement in stability of liposomal suspensions.
