FIELD: medicine, pharmaceutics.
SUBSTANCE: invention discloses pharmaceutical composition for controlled release regarding toxic active compounds, in particular, bioactive proteins from class of interferons. Composition contains bio-degradable block-copolymer made of poly(ethyleneglycol)terephthalate (PEGT) in amount from 50 to 95%, and poly(butyleneterephthalate) (PBT). Agent may be represented as injection microparticles, injection liquid, capable of independent gel or solid implant formation. Besides, invention provides a pharmaceutical set, including specified composition, methods of composition making and pharmaceutical versions of its application.
EFFECT: invention provides for initial release within 4 hours of not more than approximately 10% of included amount of one or more alpha-interferons and at least 80% of one or more alpha-interferons are released in monomer non-aggregated form.
