Abstract
The invention relates to a packaging container for inhibiting the discoloration of tobramycin eye drops and a preparation method of the packaging container. The invention provides a new method for stabilizing tobramycin eye drops, which has the defect that the quality of the prior tobramycin eye drops is unstable due to color change during stability investigation.
Description
Technical Field
The invention relates to the field of eye medicaments, in particular to a packaging container for inhibiting the discoloration of tobramycin eye drops so as to improve the stability of the tobramycin eye drops and a preparation method thereof.
Background
Eye drops commonly used for treatment of eye diseases such as conjunctivitis, keratitis and iritis of the eye caused by bacterial infection of the eye and the like comprise eye drops such as gentamicin, ofloxacin, kanamycin, polymyxin beta and the like, but along with the prolonging of clinical use time and the increase of use frequency, the medicine generates drug resistance and cross drug resistance to bacteria such as staphylococcus aureus, pseudomonas aeruginosa, escherichia coli and the like, so that the clinical curative effect is greatly influenced.
Tobramycin is aminoglycoside antibiotic with molecular formula C18H37N5O9Molecular weight of 467.52, and structural formula as follows:
the chemical structure of the tobramycin is similar to that of gentamicin, and compared with other aminoglycoside antibiotics, the tobramycin has the advantages of wider antibacterial spectrum, higher curative effect and smaller toxic reaction; the tobramycin eye drops can penetrate through corneal tissues to reach the anterior chamber, so that the eye drops can also play an effective bacteriostatic role in infection from the deep layer of the cornea to the anterior chamber, and the tobramycin is easy to dissolve in water, so that the eye drops can be used as an ideal medicine for treating the infection of sensitive strains of the external eye and the appendage in a local anti-infection manner.
Tobramycin eye drops are marketed by the american firm on 3/15 1981 under the trade name "TOBREX", which is mainly used for topical infections of the outer eye and appendages by sensitive bacteria. The quality evaluation of domestic tobramycin eye drops published in the Chinese antibiotic journal describes that the domestic tobramycin eye drops have general overall quality, the effective period is 2 years, the storage method is in a cold and dark place, and in addition, the detection standard and the inspection method are both lower than the import standard, which indicates that certain unstable factors exist in the product; the stability of tobramycin in aqueous solution was studied in Brandl and Gu 1992 and they concluded that although tobramycin was hydrolyzed at extreme pH values, the major degradation pathway of tobramycin at neutral pH values (pH 5.8-7.4) was oxidative degradation, with the major degradation impurities being niberylamine, desmethoxystreptomycin, and desmethoxystreptomycin-caylamine; the stability of tobramycin eye drops of different prescriptions was investigated in 2015 by Maria Ana Rosasco et al, and the results also indicate that the main degradation pathway of tobramycin in eye drops is oxidation, and the color of tobramycin changes under different investigation conditions.
The above research suggests that tobramycin ophthalmic solutions are unstable and methods for stabilizing tobramycin ophthalmic solutions need to be developed.
Documents of the prior art
The Maria Ana Rosasco and other researches explore a method for reducing the tobramycin degradation and slowing down the color change of the tobramycin eye drops by changing the prescription composition, thereby ensuring the product quality and prolonging the effective period. The defects of the prior art are shown in that the research result takes the appearance and the pH value of the product as evaluation indexes, and only half of the formula is found to ensure the product quality for two years at the set environmental temperature; only one formula pH can guarantee three years under the same conditions, but there is a change in color; the five compositions can ensure the stability for four years or longer by inspection under the refrigeration condition; one formulation is unstable under any examination conditions. The information does not report the impurity degradation condition of the tobramycin, and the reported results show that detailed stability research needs to be carried out on the product, the problem of unstable quality of the tobramycin eye drops is not solved essentially by changing the prescription, and other methods for stabilizing the tobramycin eye drops need to be developed.

The detection method refers to the quality standard of 'tobramycin inhalant' of USP42, and on the basis, the detection is carried out according to the product stability characteristics and the detection method which is described in the relevant guiding principle requirements of 'Chinese pharmacopoeia' 2020 edition and verified by methodology.
Table 5: content of substance of interest in each of the sample solutions
Analysis of the above example solution results: comparative example 2 is an example using only PE packaging container, and compared with other examples, the content of related substances of the solution is obviously increased after stability examination, which shows that tobramycin eye drops can inhibit oxidative degradation and improve the stability of the solution when filled into PE packaging containers containing various antioxidants and combinations; comparative examples 5 to 10 are examples of packaging containers containing different antioxidants and combinations, example 1 is an example containing an antioxidant 1076, and after the examination of the sample solutions of comparative examples 5 to 10 and example 1, the contents of related substances are increased to a certain extent, and the obvious difference between example 1 and comparative examples 5 to 10 suggests that the tobramycin eye drops can be effectively inhibited from oxidative degradation and the solution stability can be improved when the tobramycin eye drops are filled into PE packaging containers containing antioxidants, especially the antioxidant 1076.
(2) Color change of the solution: respectively filling sample solutions into 5mL packaging containers containing different antioxidants, and performing test investigation on medicinal preparations packaged in a semi-permeable container according to a test guidance principle of preparation influence factors in 9001 raw material medicaments and preparation stability test guidance principles in the four parts of China pharmacopoeia 2020 edition by an investigation method, wherein the test guidance principle is that intensive light irradiation tests are provided for each example and are placed in an adjustable illumination box, and are exposed to a cold white fluorescent lamp and a near ultraviolet lamp at the same time, and the test investigation time points are respectively 0 day, 10 days and 30 days under the condition that the illumination is 4500lx +/-500 lx; the evaluation method is that according to the item < color > in the item "tobramycin eye drops" of the second part of the 'Chinese pharmacopoeia' 2020 edition, if the product is colorless, the product is not darker than yellow or yellow-green No. 2 standard colorimetric solution (general rule 0901 first method). ", the results are shown in Table 6.
Table 6: color change of each sample solution
Analysis of the above example solution results: comparative example 2 is an example of a packaging container using only PE, comparative examples 5 to 10 are examples of packaging containers containing different antioxidants, and example 1 is an example of a packaging container containing an antioxidant 1076. The color change of each of the sample solutions of comparative examples 2,5-10 and example 1 was substantially consistent after examination. It is suggested that tobramycin ophthalmic solutions, whether packed in a PE packaging container containing an antioxidant or not or containing several antioxidants, show no significant improvement in their color change.
The experiment proves that various antioxidants are added into a packaging container (PE material) of the bremycin eye drops, so that the oxidative degradation of the bremycin eye drops can be effectively inhibited, the content of related substances can be reduced, and the color change is not improved.
Run 1.3: inspection toolPackaging container for placing bleomycin eye drops in different container materials containing antioxidant 1076

Table 8: content of substance of interest in each of the sample solutions
Analysis of the above example solution results: comparative examples 11 and 12 are PP packaging containers and PET packaging containers containing the antioxidant 1076, respectively, and the contents of the substances involved in the solution were reduced to some extent after stability examination compared with comparative examples 3 and 4 containing no antioxidant, which indicates that the antioxidant 1076 added to the packaging containers (PP and PET materials) for the butomycin ophthalmic solution can effectively inhibit oxidative degradation of the butomycin ophthalmic solution, thereby reducing the substances involved.
However, in comparative examples 11 and 12, which are respectively a PP packaging container and a PET packaging container containing an antioxidant 1076, the contents of the substances in the solutions were increased to some extent and the difference was significant as compared with example 1. The tobramycin eye drops are suggested to be filled into a PE packaging container 3 containing an antioxidant 1076, the rising trend of oxidative degradation impurities is minimum, and the effect is optimal.
The experiment proves that the antioxidant 1076 can effectively inhibit the oxidative degradation of the butomycin eye drops by being added into the packaging containers (PP and PET materials) of the butomycin eye drops made of other materials, thereby reducing related substances; meanwhile, the tobramycin eye drops are filled into a PE packaging container 3 containing an antioxidant 1076, the rising tendency of oxidative degradation impurities is minimized, and the effect is optimal.

The detection method refers to USP42 quality standard of tobramycin inhalant, and is based on the product stability characteristics according to the 2020 edition of Chinese pharmacopoeiaThe assays were performed using the assays described in the guidelines and validated by methodology.
Table 10: content of substance of interest in each of the sample solutions
Analysis of the above example solution results: the content of the substances in comparative examples 13 and 14 is obviously increased after stability test, and the content of the substances in examples 2, 3 and 4 is reduced after stability test, but the content is still different from that in example 1. The suggestion is that in order to ensure the quality of the tobramycin eye drops, the weight ratio of the antioxidant to the container material is 0.002-2.5: 1, preferably 0.002 to 0.05, most preferably in a ratio of 0.005: 1.
This experiment determined the ratio of antioxidant to container material of the PE packaging container.
Run 1.5: the migration condition of antioxidant 1076 in the stability investigation process of the tobramycin eye drops is investigated
The method comprises the following steps: respectively taking tobramycin eye drops for 0 month, 3 months and 6 months of accelerated investigation, precisely measuring 5ml of tobramycin eye drops, passing through a solid phase extraction column at a flow rate of 2-3 ml/min (respectively activating with 4ml of methanol and 4ml of water before use), washing with 2ml of water, and passing a washing solution through a solid phase extraction column; then eluting with 2ml of methanol and a mixed solution of toluene and methanol (1: 1), collecting the eluent in a 10ml measuring flask, adding the mixed solution of toluene and methanol (1: 1) to a constant volume to a scale, shaking up, taking the subsequent filtrate as a sample solution, and preparing two solutions in parallel. The results are shown in Table 11.
Table 11: measurement result of migration of antioxidant 1076 (. mu.g/ml)
Note: "/" indicates no detection
Analysis of the above example solution results: the antioxidant 1076 was not detected in the chemical solutions of the comparative examples and examples; the tobramycin ophthalmic solution was filled in a PE container containing an antioxidant 1076, and neither antioxidant 1076 migrated into the solution.
This experiment demonstrates that the use of an effective ratio of antioxidant to container material of the packaging container is premised on the fact that the antioxidant does not migrate to the tobramycin ophthalmic solution.
In conclusion, the antioxidant 1076, as a typical monophenol type semi-hindered phenol antioxidant, has a structure in which an alkyl long chain is introduced at the hydroxyl group para position, and thus has an increased molecular weight and a reduced solubility and volatility compared with the conventional antioxidant BHT, and is not likely to enter the environment; the antioxidant 1076 is added into the container material of the tobramycin eye drop packaging container, does not migrate into the eye drops through inspection, and simultaneously effectively inhibits the oxidative degradation of the tobramycin, thereby ensuring the quality of the eye drops and improving the medication safety.
Run 2.1:inspecting the color of tobramycin eye drops in a packaging container containing different proportions of titanium dioxide powder to prepare color master Change of color
