Description
Technical field
The invention belongs to technical field of medicine.Be specifically related to compound lysoamidase spray agent and preparation method.
Background technology
Lysoamidase is a kind of novel antibiotic enzyme external used medicine medical or for animals that obtains from a kind of culture fluid of pseudomonas bacillus, has very strong bacterolysis and protein dissolution ability.The easy moisture absorption of Lysoamidase powder, do not have smell, tasteless.Soluble in water, in ethanol and chloroform, do not dissolve.Lysoamidase is made of the albumen of 90% polysaccharide and 10% that (polysaccharide is electronegative, has numerously in N-acetyl-glucosamine, and the cellular construction that N-acetylated mannan alditol and N-acetyl galacturonic acid three constitute is formed.Protein part is made up of nearly 20 kinds of different albumen, and bacteriolyze albumen is wherein arranged, as phosphoric acid (ester) enzyme and protease).The original main dosage form of Lysoamidase is a lyophilized powder, can be used as surgery local application, and application method mainly contains: the filling wound, irrigate, and gargle soak.Medical science and biological experiment confirm: some lysozyme has proteolytic activity among the Lysoamidase, can remove wound rots to organize, the downright bad part of suppurative wound is come off rapidly, have simultaneously and promote immunity and quicken epitheliogenic effect, the endopeptidase that in hydrolysis staphylococcus aureus process, plays a major role a kind of lysozyme that comes to this with proteinase activity.Under proper condition, Lysoamidase dry powder can be preserved 3 years.
Lysoamidase can destroy the cell wall that antibiosis is have the gram positive bacteria (as: staphylococcus, streptococcus) of resistance, and is the most effective to staphylococcus aureus.Lysoamidase and polymyxin B are compound, can wider antibacterial action be arranged to gram negative bacteria, for example: actinomyces pseudonecrophorus, bacteroid, escherichia coli, pseudomonas putida, bacillus pyocyaneus, Salmonella, common degeneration bacterium, degeneration bacillus.
Lysoamidase in the clinical experiment process, be mainly used in after suppurative fistula, mastitis, the operation before stomach wall and lower limb wound and by the acute soft tissue that the pathogenic staphylococcus that antibiosis is have resistance causes suppurate (as cellulitis, abscess, suppurative cellulites).To above-mentioned all situations, Lysoamidase demonstrates good effect: compare with the matched group of being treated by conventional medicament, treatment time has shortened 2 times.In the clinical trial,, show bacteriolyze, removing the necrotic tissue and tissue regeneration promoting effect equally with Lysoamidase and the compound treatment that is used for oral disease of polymyxin B.Suppurative wound and burn, the dermatosis (folliculitis, furunculosis, other forms of pyoderma) that the suppuration inflammation is arranged, post-surgical trauma, scald, trophic ulcer, mastitis and endometritis, periodontal tissue and oral disease, pulpitis, periodontitis, central osteomyelitis, oral mucosa cavity, throat pain, naso-pharynageal disease.
But because Lysoamidase is unstable in aqueous solution, feasible formulation development for it is restricted, and uses also to be affected.
Summary of the invention
Technical problem to be solved by this invention is to solve the stability problem of composite lysozyme Lysoamidase in aqueous solution, provide a kind of easy to use, antibacterial effect is obvious, stay-in-grade Lysoamidase spray.
Compound lysoamidase spray agent disclosed by the invention contains 0.1%～1.0% active component Lysoamidase, 0.05～10.0% antioxidant and 0.05～10.0% antioxidant synergist, and is solvent with pH for the 3.0-9.0 buffer.
Wherein antioxidant mainly is selected from antioxidant such as sulfur-containing compound, enediol class, amino acids, comprise: thiourea, thioglycerol, 5-sulfo--D-glucose, tocopherol, natrium malicum, sodium L-ascorbate-2-phosphate, L-glutathion, L-cysteine L-methionine, L-leucine and bovine albumin etc., have prior to oxidation of drug, suppress the effect of free radical chain reaction.
Antioxidant synergist is selected from metal-chelator, organic acid and amino acids, have and the complexation of trace metal catalyst, thereby the pH value that perhaps reduces solution reduces oxidation potential, perhaps reduces the stability of oxygen in the solution and the effect of content.Comprise: diethylamine tetraacethyl sodium salt, diethylamine tetraacethyl calcium salt, succinic acid, fumaric acid, tartaric acid, citric acid, glycine, cysteine and tryptophan etc.
The pH3.0-9.0 buffer is selected from sodium dihydrogen phosphate+sodium hydrogen phosphate buffer, sodium hydrogen phosphate+citrate buffer solution, sodium hydrogen phosphate+potassium phosphate buffer, Tris+ hydrochloride buffer, potassium dihydrogen phosphate+sodium hydrate buffer solution, glycine+sodium hydrate buffer solution and sodium carbonate+sodium bicarbonate etc.The soluble inorganic salt ion such as the K that contain in the buffer
+, Ca
2+, Na
+, PO
4 3-Deng, have the bacteriostatic activity that strengthens medicine, be equivalent to the effect of activator.
According to the use position difference of spray, in preparation, can also add other auxiliary elements, as diluent, flavoring agent etc.
Another technical problem to be solved by this invention is to provide the preparation method of above-mentioned compound lysoamidase spray agent.
The method of the invention comprises the following steps:
(1) preparation pH3.0-9.0 buffer;
(2) add composite lysozyme Lysoamidase in buffer, the w/v of composite lysozyme and buffer is about 1: 100-1000w/v, stir and make it dissolving, homodisperse;
(3) add antioxidant, antioxidant synergist and other adjuvants, fully stir and make its dissolving;
(4) filter the packing spray container completely of going into to sterilize, low temperature 4-6 ℃ preservation.
The spray dosage is little, and the dosage size is scalable easy to control, convenient drug administration, and be different from aerosol, and do not add propellant, do not need pressure vessel, technology is simple, compliance with environmental protection requirements.
To body surface, mucosa and cavity/canal drug administration, topical therapeutic can be applied to spray, whole body therapeutic can be applied to again.The blood capillary of nasal cavity, oral cavity and other tract mucosas is abundant, after medicine is absorbed, directly enters blood circulation, can avoid the destruction of enzyme in the gastrointestinal tract and liver to the first-pass effect of medicine, helps bioavailability and improves.
Lysoamidase spray of the present invention is according to the oral hygiene principle design, and effective ingredient infiltrates interior tissue by local lesion's spraying, has ultra-fine shape spraying, and penetration can directly act on wound surface by force, and lasting medicine is concentrated, instant effect.Can be effectively press down antibacterials such as the staphylococcus aureus that causes pharyngolaryngitis, tonsillitis, oral ulcer, gingivitis, periodontitis, pericoronitis, papillary gingivitis extremely, Hemolytic streptococcus, streptococcus pneumoniae, big enterococcus, Candida albicans, fungus anaerobe, the sterilizing rate height.But said preparation has specificity kills noxious bacteria in the oral cavity, the protection profitable strain, and life-time service can not produce drug resistance; Safety non-toxic is non-stimulated to mucosa simultaneously, and long-term frequent use is without any side effects; Also have bactericidal antiphlogistic, resist various infection, human body immunity improving power is quickened wound healing, the function of tissue repair.
Carry out antibiotic comparative test with compound lysoamidase spray agent of the present invention and cephalosporins medicine, the result shows that the fungistatic effect of compound lysoamidase spray agent of the present invention is better than the first generation cephalosporins medicine cefalexin of present Shanghai consumption maximum.
Stability test shows, compound lysoamidase spray agent formulation products of the present invention can be stablized and stored 1 year, and the preparation that does not add antioxidant is tired obvious reduction is just arranged January, in the time of 1 year without any bacteriostatic activity.
