Definitions
- Perfluorocarbon gas-transferring emulsion for biomedical purposes composition, preparation method and treatment agent (options)
- the invention relates to the life sciences industry and relates to a composition, a method for producing and using perfluorocarbon gas-transferring emulsions, intended for use as synthetic perfluorocarbon blood-replacing agents and agents for treating various diseases, as well as perfusion, radiopaque and cosmetic agents.
- compositions of perfluorocarbon emulsions are provided.
- Perfluorocarbon emulsions are a dispersion of a liquid phase (perfluorocarbons) distributed in another liquid (water) - a dispersion medium. Such a disperse system in the state of aggregation has the designation F / F.
- the dispersed medium is a polar liquid - water.
- Perfluorocarbon emulsions are direct emulsions. Most dispersed systems with a liquid dispersed medium are aggregatively unstable, i.e. lyophobic, they include perfluorocarbon emulsions - thermodynamically nonequilibrium colloidal systems.
- dispersed systems depend on the number of particles of the dispersed phase. When there are few particles and the contact between them is insignificant and the particles are able to move relative to each other, such dispersed systems are
- Perfluorocarbon emulsions belong to free-dispersed systems, while the number of particles in 1 liter of 20% emulsion of perfluorocarbons is 1.53 x 10 18 .
- the dispersion method the most suitable for producing nanoemulsions, is based on a mechanical method of overcoming intermolecular forces. Dispersion using high pressure homogenizers causes the grinding of perfluorocarbons to submicron sizes. In this case, the dispersion increases very strongly and a dispersed system is formed with a developed specific surface, i.e. when an emulsion is formed during the dispersion of two liquids, the interface is not reduced, but increased. The fragmentation of the dispersed phase gives the dispersed systems special qualities associated with the size of the interface between the dispersed phase and the dispersed medium.
- the homogenization efficiency is determined by the average particle diameter of the resulting dispersed phase.
- perfluorocarbon emulsions can be conditionally divided into two types in general terms - these are monodisperse and polydisperse emulsions.
- the size of the polydispersed emulsions is in the range from 0.1 ⁇ m (100 nm) to 10 ⁇ m and higher, which corresponds to the size of the medium and coarse systems.
- the size of monodisperse emulsions is in the range from 1 nm (10 ⁇ 9 m)
- the substance - perfluoroemulsion nanoparticles (10 ⁇ 8 m) will have special properties, since this state is a special intermediate between molecular compounds and the ultrafine (colloidal) state of the substance.
- the range of particle sizes in the range from 10 to 30 nm (10 "8 m) is already transitional.
- perfluorocarbons are used simultaneously.
- One of them is selected from the group (Cs-Syu) containing, for example, perfluorodecalin (PFD) C 10 F 18 or perfluorotripropylamine (PFPA) C 9 F 21 N, or perfluorooctyl bromide (PFOB) C 8 F 17 Br, the second from the group (C 11 -C 12 ) containing, for example, perfluoromethylcyclohexylpiperidine (PFMCP) C 12 F 2 zN or perfluorotributylamine (PFBA) C 12 F 27 N.
- PFD perfluorodecalin
- PFPA perfluorotripropylamine
- PFOB perfluorooctyl bromide
- C 11 -C 12 containing, for example, perfluoromethylcyclohexylpiperidine (PFMCP) C 12 F 2 zN or perfluorotributylamine (PFBA)
- SUBSTITUTE SHEET (RULE 26) 760 mmHg Art.), as a result of which, they began to be used as the main component - a gas carrier, when creating synthetic blood substitutes.
- perfluorocarbons are insoluble in water and other liquids, therefore, they can be used only in the form of emulsions with a certain size of perfluorocarbon particles coated with a layer of emulsifier (proxanol or phospholipid).
- proxanol or phospholipid proxanol or phospholipid.
- the smaller the particle size of the emulsion the better, because the emulsion is administered intravenously and with large particle sizes, emulsion formulations can cause embolism (blockage) of blood vessels, as well as severe adverse reactions to the presence of coarse particles of the emulsion.
- the concentration of perfluorocarbons is 24% in a physiologically acceptable aqueous medium.
- the disadvantages of this composition in the specified invention should include the fact that the composition of the emulsion has a sufficiently coarse particle size and cannot be stored in thawed form, and
- the average particle diameter in the composition of this emulsion was also large, due to the fact that at high temperatures in the process of emulsification and pasteurization coarsening of the particles of the emulsion.
- the particles used in the composition of the perfluorocarbon emulsion coarsen rather quickly even at room temperature (Mitshio T.

- the disadvantages of this composition include the low concentration of perfluorocarbons in the emulsion - not higher than 20%, which significantly narrows the scope.
- the closest to the claimed composition is an emulsion based on organofluorine compounds for biomedical purposes (RF patent Ns 2199311, publ. In the bulletin "Discoveries, inventions . -- 02.27.2003, N ° 6), in which perfluorodecalin is present, perfluoromethylcyclohexylpiperidine concentration of 1-30%, emulsifiable 0.2-6% proxanol.
- the disadvantage of this emulsion is the low concentration of perfluorocarbons in the emulsion composition - not higher than 30%, which significantly narrows the scope.
- SUBSTITUTE SHEET (RULE 26)
- the most common methods for producing perfluorocarbon emulsions are based on methods using ultrasound or homogenization on high pressure disintegrants.
- a homogenization method is preferable, because it allows to obtain emulsions in big quantities and with better physical and chemical characteristics, e.g., improved particle size distribution (Jeap G. Riess and Maurice Le Vlaps Rreraratiop ° F rerfluoro-shemisal emulsiops bioshemisal for use:. rripsirles. apd materials Norwood ElHs methods. Series IP Biomedisippe, VCH 5 Vlod Substituts, Preraratiop, Prusiolog apd Media Arlistiopi. 1991. Ch. 5, pp 113-115).
- the initial perfluorocarbon emulsion is prepared by mixing the components in a physiologically acceptable aqueous medium using a homogeneous mixer or propeller mixer, then the initial emulsion is emulsified by injection in a high pressure homogenizer at a pressure of from 100 to 500 atm. and temperatures up to +55 degrees C 0 .

- the disadvantage of the above method for producing perfluorocarbon emulsions is the long-term emulsification of perfluorocarbons - 9 cycles, the inability to obtain a highly concentrated emulsion (over 40%) and the inability to sterilize emulsions.
- the disadvantage of the above-described method for creating perfluorocarbon emulsions is the inability to obtain highly concentrated emulsions (over 40%) due to the presence of one extrusion device of a homogenizer, long emulsification time (for example, 10 liters of 10 vol.% Emulsion is produced in 3-4 conditional hours), which due to the presence of only one working extrusion device of the homogenizer in which the formation of the emulsion. This leads to a prolonged presence of the operator in a sterile box and the possible sterilization (insemination) of the emulsion.
