Description
Technical field
The invention belongs to pharmaceutical technology field, in particular it relates to a kind of raising phylloxanthin drug injection preparation stability
Medicinal composition for injections.
Background technology
Phylloxanthin is the alkaloid extracting from chuanxiong, and chemical constitution is tetramethylpyazine, be a kind of new calcium from
Sub- antagonist, have blood circulation promoting and blood stasis dispelling, anti-platelet aggregation, excited medullary respiratory center and vasomotor center, expansion of blood vessels and
Bronchial smooth muscle, improve multiple effect such as microcirculation, be clinically used for for obliterated cerebral vascular disease such as incomplete brain blood supply, brain
Thrombosiss, cerebral embolism and other ischemic angiopathys such as coronary heart disease, vasculitiss etc..The injection of phylloxanthin has been Chinese medicine
Treatment modern hardly possible disease makes very big contribution.
Due to phylloxanthin dissolubility extreme difference in aqueous, therefore it is made into phylloxanthin hydrochlorate or phylloxanthin phosphate
To increase its water solublity.Presently commercially available phylloxanthin injection mainly has the phosphatic low capacity of phylloxanthin hydrochlorate, phylloxanthin
Injection, and add glucose or sodium chloride to adjust as osmotic pressure in phylloxanthin hydrochlorate, phylloxanthin phosphate solution
The high-capacity injection that agent is made.But when preparing above-mentioned injection it is necessary to the pH value of medicinal liquid is adjusted to suitable human injection
The certain limit of administration, the pH value regulator that current document report uses is sodium hydroxide solution or uses hydrochloric acid solution, phosphorus
Acid solution, but easily analysed under the conditions of long-term storage and winter low temperature using the phylloxanthin injection of above-mentioned pH value regulator preparation
Go out the precipitate such as tiny white point, white block, solution muddiness, cause the visible foreign matters check item of product unqualified.Prior art be
Add polyoxyethylene sorbitan monoleate in solution as cosolvent, occur that small particles, white block, solution muddiness etc. are sedimentary to ask to solve product
Topic.But polyoxyethylene sorbitan monoleate is due to having the effect of haemolysis and blood pressure lowering, and easily become sour in storage and autoclaving process, lead to
Injection clinical practice risk containing polyoxyethylene sorbitan monoleate is higher, makes troubles to clinical application and popularization.
Content of the invention
The technical problem to be solved is to provide a kind of injection improving phylloxanthin drug injection preparation stability
Pharmaceutical composition.
This medicinal composition for injections adopts oxalic acid, Disodium oxalate. as pH adjusting agent, and finds to adopt by creative work
During with oxalic acid, Disodium oxalate. as pH adjusting agent, medicinal liquid pH value is more stable, and lutein degradation material drops significantly compared with prior art
Low, in the case of avoiding increasing the cosolvent of clinical practice risk using other, phylloxanthin injection is satisfactorily addressed
Liquid muddy problem of the tiny white point of easy precipitation, white block, solution under the conditions of long-term storage and winter low temperature.
The present invention solves the above problems and be employed technical scheme comprise that：A kind of raising phylloxanthin drug injection preparation stability
Medicinal composition for injections, mainly water for injection is dissolved in by the salt of phylloxanthin, adds osmotic pressure regulator, and add oxalic acid
And/or the medicinal composition for injections that Disodium oxalate. is made as pH adjusting agent regulating liquid medicine pH value, described oxalic acid and/or Disodium oxalate.
Consumption be 0.1mg～200.0mg/100ml.
Described osmotic pressure regulator is glucose, sodium chloride, xylitol, Mannitol, any one or a few in Fructose.
The consumption of osmotic pressure regulator is prior art, and sodium chloride consumption is 0.9g/100ml；Glucose, xylitol, Mannitol, Fructose
Consumption is 5g/100ml～10g/100ml.
The salt of described phylloxanthin includes phylloxanthin hydrochlorate, phylloxanthin phosphate.
The concentration of the salt of described phylloxanthin is calculated as 10mg～10g/100ml with phylloxanthin.
Described medicinal liquid pH value is 3.0～6.0.
Described phylloxanthin drug injection preparation formulation is injection.
The preparation method of the medicinal composition for injections of above-mentioned raising phylloxanthin drug injection preparation stability, including following
Step：
(1) salt weighing phylloxanthin is with phylloxanthin amount of calculation 0.1g～100g, oxalic acid and/or Disodium oxalate. 2mg～4.0g；
(2) oxalic acid, Disodium oxalate. are configured to the solution of 10g/100ml～20g/100ml respectively, standby；
(3) salt of phylloxanthin, sodium chloride add in 30 DEG C～40 DEG C of water for injection 500ml, stir to after be completely dissolved,
The activated carbon adding, described activated carbon dosage is 0.02g/100ml, stirs 15 minutes, filters decarburization；
(4) step (3) gained filtrate step (2) configures oxalic acid and/or sodium oxalate solution adjust pH value be 3.0～
7.0, the water for injection adding less than 40 DEG C (30 DEG C～40 DEG C) is to 1000ml；
(5) by step (4) gained medical filtration to clarification, fill, sterilizing, obtain final product.
Described step (1) mesoxalic acid consumption is 1mg～2.0g, Disodium oxalate. consumption is 1mg～2.0g.
Osmotic pressure regulator 9.0g is also included in described step (1).
Described osmotic pressure regulator is sodium chloride.
In such scheme, add that oxalic acid and/or Disodium oxalate. refer to add can be oxalic acid, any one in Disodium oxalate.,
Or oxalic acid, Disodium oxalate. are with arbitrary proportion proportioning；In step (2), one of the oxalic acid of addition, Disodium oxalate., then make
A kind of solution, such as includes oxalic acid, two kinds of Disodium oxalate., is then configured to solution for standby respectively；The salt of phylloxanthin, osmotic pressure regulator
Consumption can adopt the consumption of prior art, according to the consumption adjustment of prior art.
In sum, the invention has the beneficial effects as follows：The present invention pass through experimental studies have found that, in phylloxanthin drug injection system
In agent, during using oxalic acid, Disodium oxalate. as pH adjusting agent, medicinal liquid pH value is more stable, and lutein degradation material is compared with prior art
Substantially reduce, in the case of avoiding increasing the cosolvent of clinical practice risk using other, leaf has been satisfactorily addressed yellow
Plain injection adopts prior art products easily to separate out tiny white point, white block, the problem of solution muddiness in storage process, permissible
Ensure that the visible foreign matters detection of the holding injection that phylloxanthin injection can be stable in storage process meets drug quality mark
Accurate regulation, is easy to clinical application and popularization.
The present invention passes through creative work, and muddy to the tiny white point separating out in phylloxanthin injection, white block, solution is former
Because being analyzed and studying, determine that deposit is mainly raw material free alkali crystallize and a small amount of catabolite, above-mentioned reason occurs
May be relevant with species sour, alkali used by the pH value of solution and pH adjusting agent.Disodium oxalate. is therefore used as pH adjusting agent, and
Oxalic acid is used as pH value counter regulation agent, in the case of avoiding increasing the cosolvent of clinical practice risk using other, to solve
Certainly this product easily separates out tiny white point, white block, the problem of solution muddiness under the conditions of storage for a long time and winter low temperature.
