Description
Technical field
The invention mainly relates to pharmaceutical technology field, and in particular to a kind of levo-oxiracetam injection and preparation method thereof.
Background technology
Cereboactive drug is a kind of new medicine for central nervous system for promoting study, strengthening memory also known as cereboactive drug.Nootropics requirement selection index system is in cerebral cortex, the feature with selection activation, protection and promotion damaged nerve cell functional rehabilitation.Different from other neurologic agents be a little their above-mentioned effect not by network or olfactory bulb, but directly act on cortex.Behavior is neither influenceed, also without calm excitation, therefore such medicine has caused the extensive concern and interest of people, and the demand to such medicine is also growing day by day.
Levo-oxiracetam chemical name is:S- (-) -4- hydroxyl -2- oxo-pyrrolidine-N- acetamides, are white micro-crystals sprills, 135~136 DEG C of fusing point, -36 ° of optical activity (C=1.00in water), and the dissolubility of levo-oxiracetam is substantially better than raceme.Chemical structural formula is shown below:
Existing levo-oxiracetam injection its be primarily present the problems such as product main ingredient dissolubility is bad, the bad oxidizable, sterilization process of product stability easily causes impurity to increase.
The content of the invention
It is an object of the invention to provide the not oxidizable levo-oxiracetam injection of a kind of good stability, product.
Preparation method another object of the present invention is to provide above-mentioned levo-oxiracetam injection.
The purpose of the present invention is realized by following technical measures:
A kind of levo-oxiracetam injection, it is characterised in that it is, with levo-oxiracetam as raw material, to add a certain amount of additives and be obtained;Wherein described additives be glucose, sodium chloride, mannitol, glycerine, Serine, sodium glutamate, alanine, glycine, lecithin, propane diols, phenmethylol, anesin, sodium sulfite, sodium hydrogensulfite, sodium pyrosulfite in, one or more of vitamin C, ethylenediamine tetra-acetic acid.
Inventor has found in research process, select a certain proportion of glycerine with glycine as compound additives in composition described above, add a certain amount of vitamin C and ethylenediamine tetra-acetic acid, coordinate specific sterilization process step, main ingredient dissolubility is good in may be such that the levo-oxiracetam preparation process of above-mentioned injection, and product total impurities increase in sterilization process is smaller, is difficult to be oxidized during product storage, above-mentioned levo-oxiracetam injection, it is characterised in that:It is with levo-oxiracetam, glycerine, mannitol, vitamin, ethylenediamine tetra-acetic acid as supplementary material, by concentrated compounding, it is dilute match somebody with somebody, embedding, sterilizing, test package step be obtained;The levo-oxiracetam 72%~78% that the consumption of wherein described supplementary material is weight percentage, glycerine 12%~16%, glycine 7%~13%, vitamin C 1%~5%, ethylenediamine tetra-acetic acid 2%~7%;Wherein described sterilization steps are that canned peace is cutd open into semi-finished product feeding steam sterilization pan sterilizing, 121 DEG C of sterilizing 15min, sterilizing program:10 DEG C/min, 121 DEG C are risen to, 15min is kept at 121 DEG C;3~5 DEG C/min of compressed air air blast lowers the temperature, and 8~12min is cooled to 70~80 DEG C, and 2~3 DEG C/min of cooling water coolings, 15~18min is cooled to 30 DEG C, and sterilizing is completed.
