Definitions
- the present invention relates to a tissue repair composition
- a tissue repair composition comprising a biodegradable polymer copolymer
- the biodegradable polymer copolymer is a copolymer obtained by polymerizing a hydrophobic biodegradable polymer and a hydrophilic biodegradable polymer is self-assembled in an aqueous solution
- a composition for tissue repair comprising a biodegradable polymer copolymer that can form nanoparticles to prevent nodules during intradermal or subcutaneous injection.
- Existing tissue repair injections contain 25 ⁇ 50um microparticles for tissue repair. This is to prevent the microspheres or particles from being destroyed by macrophages, and is highly related to the durability of the repair effect.
- various side effects may occur with micro-sized tissue repair materials, and it is known that the representative side effects include ischemia or mass compression effects, such as blood circulation disorders or nodules in the tissue at the injection site.
- Existing tissue repair materials are recommended to be injected into the subcutaneous fat layer, which contains relatively few fibroblasts, rather than the dermal layer, which contains many fibroblasts involved in collagen production, due to concerns about side effects, and requires high skill of the operator.
- microparticles for tissue repair that help collagen production such as commercialized polycaprolactone or polylactic acid, are injected into the dermis, the probability of nodules is very high.
- Patent Publication No. 10-2016-0107780 composition for tissue repair
- Patent Publication No. 10-2015-0010464 a hydrophobic biodegradable polymer and a hydrophilic biodegradable polymer comprising a polymer polymerized) injections for tissue repair
- the weight specific gravity of the hydrophobic biodegradable polymer is high, when directly injected into the body, there is a very high risk of nodules or the like occurring due to recombination between the hydrophobic biodegradable polymers.
- Patent Document 1 Patent Publication No. 10-2016-0107780
- Patent Document 2 Patent Publication No. 10-2015-0010464
- an object of the present invention is to provide a composition for tissue repair excellent in tissue repair effect due to a high collagen production rate without generating nodules even when directly injected into the dermis.
- the present invention provides a tissue repair composition comprising a biodegradable polymer copolymer.
- the present invention provides an injection injection for tissue repair comprising the composition for tissue repair.
- the biodegradable polymer copolymer is a polymer obtained by polymerizing a hydrophobic biodegradable polymer and a hydrophilic biodegradable polymer.
- the hydrophobic biodegradable polymer may be polycaprolactone, polylactic acid, polyglycolic acid, polydioxanone and polyhydroxybutylate, but preferably polycaprolactone.
- the hydrophilic biodegradable polymer is not limited, but may be carboxymethyl cellulose (CMC), polyethylene glycol, monomethoxy polyethylene glycol, etc., but is preferably polyethylene glycol or monomethoxy polyethylene glycol.
- CMC carboxymethyl cellulose
- polyethylene glycol polyethylene glycol
- monomethoxy polyethylene glycol etc.
- the hydrophobic biodegradable polymer and the hydrophilic biodegradable polymer are preferably polymerized in a weight ratio of 10: 20 to 10: 50, more preferably in a weight ratio range of 10: 20 to 10: 30.
- the hydrophobic biodegradable polymer preferably has a number average molecular weight of 550 to 4000 g/mol, more preferably 750 to 1500 g/mol.
- the hydrophilic biodegradable polymer may have a number average molecular weight of 400 to 4000 g/mol, preferably 800 to 2000 g/mol.
- the copolymer obtained by polymerizing the hydrophobic biodegradable polymer and the hydrophilic biodegradable polymer may have a number average molecular weight of 2000 to 16000 g/mol, preferably 2500 to 5000 g/mol.
- the biodegradable polymer copolymer obtained by polymerizing the hydrophobic biodegradable polymer and the hydrophilic biodegradable polymer may be contained in an aqueous solution in an amount of 0.1 to 99% (w/w), preferably 0.1 to 50, more preferably 0.1 to 30% (w/w) may be included. If it is out of the above range, a problem may occur in skin injection using a syringe due to an increase in the viscosity of the aqueous solution.
- the biodegradable polymer copolymer obtained by polymerizing the hydrophobic biodegradable polymer and the hydrophilic biodegradable polymer may have a spherical shape of 50 nm to 1000 nm, preferably a spherical shape of 50 nm to 300 nm.
- a catalyst may be used to prepare the copolymer, and the catalyst may include stannous octoate, but is not limited thereto.
- composition may further include additives such as additives, solvents or gelling agents commonly used in the art for use as injections.
- composition for tissue repair of the present invention unlike the existing composition for main use, does not generate nodules even when directly injected into the dermis, and the collagen production rate is high, and thus the tissue repair effect is excellent.
