This shows; From racemization alpha-tocopherol and Vitamin C content decline situation; The application's antioxidant combination has the effect that more significantly improves preparation stability, and the combined effect that other antioxidants are asked in all not having originally is remarkable, and citric acid and cysteine hydrochloride are when using separately; Very low antioxidation is only arranged, explain that antioxidant citric acid of this experimental group and cysteine hydrochloride combination have collaborative antioxidation; Simultaneously because citric acid and cysteine hydrochloride are water-soluble substanceses; And the racemization alpha-tocopherol is a liposoluble substance; Experiment proof antioxidant citric acid and cysteine hydrochloride combination not only have antioxidation to water soluble ingredient; And liposoluble substance also possessed antioxidation, produced the technique effect that those skilled in the art can't reckon with. wherein consider the consumption factor best be the combination of the application's experimental group 5.And further experiment shows, when using the conventional cosolvent of prior art, above-mentioned comparative result is not had appreciable impact.
According to above-mentioned result of the test, we adopt identical prescription, add excipient; Be prepared into freeze-dried powder, place 24 months by above-mentioned similarity condition after, be dissolved into injection with 5ml water for injection for every bottle; Measure racemization alpha-tocopherol and Vitamin C content, the result sees table 2.
Table 2 freeze-dried powder is placed racemization alpha-tocopherol and Vitamin C content result after 24 months
Annotate: compare * P<0.05 with the Comparative formulation group;
Table 2 is the result show, antioxidant combination of the present invention has the effect that more significantly improves preparation stability, is superior to the antioxidant of prior art.
Comparison sheet 1 and table 2 result can also find that the stability of lyophilized injectable powder is superior to injection; Although the comparative example measured value is lower than the experimental group measured value in the table 2, require from pharmaceutical formulations, except that Comparative Examples 5, all the other Comparative Examples all meet the requirements.
The comparative experiments of bacteriostasis
For carry out this experiment, prepare the injection that contains 13 kinds of vitamin combinations by conventional method, the basic prescription as follows:
Water for injection adds to 5000ml, and pH6.0 processes 1000.
Or add excipient glycine 250g, water for injection adds to 2500ml, processes 1000 bottles of lyophilized injectable powders.
Sample 1 is the injection of basic prescription preparation;
Sample 2 adds disodium edetate 1000mg, nipabutyl sodium 1000mg, the injection of preparation for basic prescription removes citric acid and cysteine hydrochloride.
Sample 3 adds the injection of disodium edetate 1000mg preparation for basic prescription removes citric acid and cysteine hydrochloride.
Sample 4 prepares lyophilized injectable powder for sample 1 adds excipient by method for preparing freeze-dried powder;
Sample 5 prepares lyophilized injectable powder for sample 2 adds excipient by method for preparing freeze-dried powder;
Sample 6 prepares lyophilized injectable powder for sample 3 adds excipient by method for preparing freeze-dried powder.
Because the ejection preparation of compound vitamin can not adopt the terminal autoclave sterilization; Because of vitamin is the necessary material of bacterial growth; Very easily bacterial growth breeding; So must add some necessary antiseptic such as sodium benzoate or sodium methyl phydroxybenzoate during conventional preparation said preparation waits and suppresses microbiological contamination; Otherwise just can't guarantee the drug quality safety of preparation in the shelf-life. so we get three kinds of sample injection liquid and three kinds of sample lyophilized injectable powders each 100 bottles long-time (15 months) are placed, and get 5 bottles of per sample (p.s.)s, and do aseptic detection by 2005 editions two appendix XIH sterility tests of Chinese Pharmacopoeia method in every month; Find that sample has detected bacterium in cultivating, and promptly is judged to be microbiological contamination. result of the test is seen table 3.
The aseptic testing result of the long-time placement of six kinds of samples of table 3
Explain: microbiological contamination is not found in-expression; Microbiological contamination is found in+expression.
Sample 3 preparations are just found microbiological contamination in February, and the 3rd, in detecting April microbiological contamination are arranged all, inspection after therefore just no longer listing in from 5th month.
Sample 6 preparations are found microbiological contamination in November, and in detecting in the 12nd, 13 month, microbiological contamination are arranged all, inspection after therefore just no longer listing in from 14th month.
Result of the test shows, the very easily microbiological contamination of compound vitamin ejection preparation needs to add antibacterial; Sample 1 though 4 do not add conventional antibacterial, has good antibacterial effect; And sample 3 and 6 is found microbiological contamination respectively, shows to use conventional antioxidant, and adding preservative agent is not dangerous; It can also be seen that from the result that in addition lyophilized formulations is more stable than injection; Further research shows that this effect possibly be citric acid and the synergistic result of cysteine hydrochloride.
Further experiment to cosolvent
In order further to compare and to seek the most stable combination of preparation particulate matter, the applicant has carried out further research.
For carry out this experiment, prepare the injection that contains 13 kinds of vitamin-medicine compositions by conventional method, the basic prescription as follows:
Water for injection adds to 5000ml, and pH6.0 processes 1000 bottles of injection;
Comparative Examples 1 is removed citric acid and cysteine hydrochloride in the above-mentioned prescription, adds disodium edetate 1000mg, nipabutyl sodium 1000mg.
