Description
Technical field
The invention belongs to pharmaceutical technology field, and in particular, to a kind of medicinal composition for injections of gingerol.
Background technology
Gingerol is extracted from ginger comprising gingerol, ginger brain etc. and mixture of the ginger in relation to spicy substance, its
Have the function that to resist lipofuscin.It is used to help prevent or treats because of nausea and vomiting caused by carsickness, pregnancy etc..With stomach invigorating
Anti-gastric-ulcer, cholagogic, liver protection, cardiac stimulant, suppress platelet aggregation, anti-corona, antitumor, CNS inhibition, strengthen immunity, antibacterial,
Desinsection, the effect of anti-inflammatory, also have very strong oxidation resistance.
Due to gingerol, dissolubility is very poor in aqueous, is made into gingerol hydrochloride or gingerol phosphate
It is water-soluble to increase it.Presently commercially available gingerol parenteral solution mainly has the phosphatic low capacity of gingerol hydrochloride, gingerol
Parenteral solution, and glucose or sodium thiosulfate are added as antioxidant in gingerol hydrochloride, gingerol phosphate solution
Manufactured high-capacity injection.But when preparing above-mentioned parenteral solution, it is necessary to adjust the pH value of liquid to suitable human injection and give
A certain range of medicine, the pH adjusting agent that document report uses at present are sodium hydroxide solution or use hydrochloric acid solution, phosphoric acid
Solution, but easily separated out under the conditions of long-term storage and winter low temperature using gingerol parenteral solution prepared by above-mentioned pH adjusting agent
The sediments such as tiny white point, white block, solution muddiness, cause the visible foreign matters check item of product unqualified.Now it yet there are no preferably
Solution.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of injecting drug use for improving gingerol ejection preparation stability
Compositions.
The medicinal composition for injections is sent out using phenylacetic acid, sodium phenylacetate as pH adjusting agent, and by creative work
During now using phenylacetic acid, sodium phenylacetate as pH adjusting agent, liquid pH value is more stablized, and gingerol degradation material is compared with the prior art
Substantially reduce, in the case where avoiding the cosolvent using other increase clinical practice risks, it is peppery that ginger has been satisfactorily addressed
The problem of plain parenteral solution easily separates out tiny white point, white block under the conditions of long-term storage and winter low temperature, solution is muddy.
Technical solution is used by the present invention solves the above problems：One kind improves gingerol drug injection preparation stability
Medicinal composition for injections, water for injection is mainly dissolved in by the salt of gingerol, adds antioxidant, and add phenylacetic acid and/or
Sodium phenylacetate is as medicinal composition for injections made of pH adjusting agent regulating liquid medicine pH value, the phenylacetic acid and/or phenylacetic acid
The dosage of sodium is 0.1mg~200.0mg/100ml.
The antioxidant is sodium thiosulfate.The dosage of antioxidant is the prior art, and sodium thiosulfate dosage is 0.9g/
100ml；Glucose, xylitol, mannitol, fructose dosage are 5g/100ml~10g/100ml.
The salt of the gingerol includes gingerol hydrochloride, gingerol phosphate.
The concentration of the salt of the gingerol is calculated as 10mg~10g/100ml with gingerol.
The liquid pH value is 3.0~6.0.
The gingerol drug injection preparation formulation is parenteral solution.
The preparation method of the medicinal composition for injections of above-mentioned raising gingerol drug injection preparation stability, including it is following
Step：
(1) weigh the salt of gingerol with gingerol calculation amount 0.1g~100g, phenylacetic acid and/or sodium phenylacetate 2mg~
4.0g；
(2) phenylacetic acid, sodium phenylacetate are configured to the solution of 10g/100ml~20g/100ml respectively, spare；
(3) salt of gingerol, sodium thiosulfate are added in 30 DEG C~40 DEG C of water for injection 500ml, are stirred to completely molten
Xie Hou, the activated carbon of addition, the activated carbon dosage are 0.02g/100ml, are stirred 15 minutes, filter decarburization；
(4) it is 3.0 that the phenylacetic acid of filtrate step (2) configuration and/or sodium phenylacetate solution obtained by step (3), which adjust pH value,
~7.0, the water for injection of less than 40 DEG C (30 DEG C~40 DEG C) is added to 1000ml；
(5) it is filling by medical filtration obtained by step (4) to clarification, sterilize, to obtain the final product.
In the step (1) phenylacetic acid dosage be 1mg~2.0g, sodium phenylacetate dosage be 1mg~2.0g.
Antioxidant 9.0g is further included in the step (1).
The antioxidant is sodium thiosulfate.
In such scheme, add that phenylacetic acid and/or sodium phenylacetate refer to add can be in phenylacetic acid, sodium phenylacetate
It is any, or phenylacetic acid, sodium phenylacetate match with arbitrary proportion；In step (2), phenylacetic acid, the sodium phenylacetate of addition
In one kind, then a kind of solution is made, such as include phenylacetic acid, two kinds of sodium phenylacetate, then be configured to solution for standby respectively；Gingerol
Salt, antioxidant dosage can use the prior art dosage, according to prior art dosage adjust.
In conclusion the beneficial effects of the invention are as follows：The present invention by experimental studies have found that, in gingerol drug injection system
In agent, during using phenylacetic acid, sodium phenylacetate as pH adjusting agent, liquid pH value is more stablized, and gingerol degradation material is more existing
Technology substantially reduces, and in the case where avoiding the cosolvent using other increase clinical practice risks, is satisfactorily addressed
Gingerol parenteral solution using the problem of prior art products easily separate out tiny white point, white block in storage process, solution is muddy,
It can ensure that the visible foreign matters detection for the holding parenteral solution that gingerol parenteral solution can be stablized in storage process meets medicine matter
The regulation of amount standard, easy to clinical application and popularization.
The present invention by creative work, to separated out in gingerol parenteral solution tiny white point, white block, solution muddiness original
Because being analyzed and being studied, it is mainly raw material free alkali crystallization and a small amount of catabolite to determine deposit, above-mentioned reason occurs
May be related with sour, alkali species used in the pH value and pH adjusting agent of solution.Therefore sodium phenylacetate is used as pH adjusting agent,
And phenylacetic acid is used as pH value counter regulation agent, in the case where avoiding the cosolvent using other increase clinical practice risks,
It is muddy that tiny white point, white block, solution are easily separated out to solve the problems, such as this product under the conditions of long-term storage and winter low temperature.
