Description
Technical field
The invention belongs to pharmaceutical technology field, in particular it relates to improve the combination of Codeine Hydrochloride ejection preparation stability
Thing preparation method.
Background technology
Codeine Hydrochloride is subordinate to codeine salt family, is a kind of oral administration solution.Its Main Ingredients and Appearance is codeine, can treat
Because extracting from Semen Papaveris, the analgesic activity of this material is that in nature, other compounds are incomparable, thus is regarded always
For releasing the maximally effective analgesic of severe pain.
Due to Codeine Hydrochloride dissolubility extreme difference in aqueous, therefore it is made into Codeine Hydrochloride hydrochlorate or hydrochloric acid
Codeine phosphate is to increase its water solublity.Presently commercially available Codeine Hydrochloride injection mainly have Codeine Hydrochloride hydrochlorate,
The phosphatic injection with small volume of Codeine Hydrochloride, and in Codeine Hydrochloride extracting solution solution, add glucose or sodium chloride
The high-capacity injection made as osmotic pressure regulator.But when preparing above-mentioned injection, it is necessary to the pH value of medicinal liquid is regulated
To being suitable for the certain limit that human injection is administered, the pH value regulator that current document report uses is sodium hydroxide solution or makes
With hydrochloric acid solution, phosphoric acid solution, but use Codeine Hydrochloride injection prepared by above-mentioned pH value regulator in long-term storage and winter
Easily separate out the precipitate such as tiny white point, white block, solution is muddy under season cryogenic conditions, cause the visible foreign matters check item of product not
Qualified.Prior art is to add polyoxyethylene sorbitan monoleate in the solution as cosolvent, small particles, white block, molten occurs solving product
The sedimentary problems such as liquid is muddy.But polyoxyethylene sorbitan monoleate is owing to having the effect of haemolysis and blood pressure lowering, and at storage and high temperature sterilize
During easily become sour, cause the injection clinical practice risk containing polyoxyethylene sorbitan monoleate higher, to clinical application and promote band
It is inconvenient to come.
Summary of the invention
The technical problem to be solved is to provide the compositions system improving Codeine Hydrochloride ejection preparation stability
Preparation Method.This medicinal composition for injections employing benzoic acid, sodium benzoate are as pH adjusting agent, and are found by creative work
When using benzoic acid, sodium benzoate as pH adjusting agent, medicinal liquid pH value is more stable, the more existing skill of Codeine Hydrochloride degradation material
Art is substantially reduced, and in the case of avoiding using other to increase the cosolvent of clinical practice risk, salt has been satisfactorily addressed
Acid codeine injection 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.
The present invention solves the problems referred to above and be the technical scheme is that the group improving Codeine Hydrochloride ejection preparation stability
Compound preparation method, comprises the steps:
(1) extracting solution 2g～40g of Codeine Hydrochloride, benzoic acid and/or sodium benzoate 5mg～3g are weighed；
(2) benzoic acid, sodium benzoate are configured to the solution of 5mg/100ml～3g/100ml respectively, standby；
(3), during the extracting solution of Codeine Hydrochloride adds the water for injection 500ml of 30 DEG C～40 DEG C, stir to after being completely dissolved, add
The activated carbon entered, described activated carbon dosage is 0.02g/100ml, stirs 15 minutes, filters decarburization；
(4) step (3) gained filtrate step (2) configures benzoic acid and/or PhCOONa solution regulation pH value be 5.0～
7.0, add the water for injection of 30 DEG C～40 DEG C to 1000ml；
(5) by step (4) gained medical filtration to clarification, fill, sterilizing, to obtain final product.
In described step (1) benzoic acid consumption be 5mg～3g, sodium benzoate consumption be 5mg～3g.
Described step also includes osmotic pressure regulator 12.0g in (1).
Described osmotic pressure regulator is sodium chloride.
In such scheme, what addition benzoic acid and/or sodium benzoate referred to addition can be in benzoic acid, sodium benzoate
Any one, or benzoic acid, sodium benzoate are with arbitrary proportion proportioning；In step (2), the benzoic acid of addition, sodium benzoate
In one, then make a kind of solution, as included benzoic acid, sodium benzoate two kinds, be configured to solution for standby the most respectively；Hydrochloric acid can
Treat because of extracting solution, the consumption of osmotic pressure regulator can use the consumption of prior art, adjust according to the consumption of prior art.
In sum, the invention has the beneficial effects as follows: the present invention, by experimental studies have found that, notes at Codeine Hydrochloride medicine
Penetrating in preparation, when using benzoic acid, sodium benzoate as pH adjusting agent, medicinal liquid pH value is more stable, Codeine Hydrochloride degradation product
Matter relatively prior art is substantially reduced, in the case of avoiding using other to increase the cosolvent of clinical practice risk, satisfactory
Solve Codeine Hydrochloride injection and use prior art products easily to separate out tiny white point, white block, molten in storage process
The problem that liquid is muddy, it is ensured that keeping that Codeine Hydrochloride injection can be stable in storage process is different seen from injection
Analyte detection meets the regulation of drug standard, it is simple to clinical application and popularization.
The present invention passes through creative work, to the tiny white point separated out in Codeine Hydrochloride injection, white block, solution muddiness
Reason be analyzed and study, determine that deposit is mainly raw material free alkali crystallize and a small amount of catabolite, occur above-mentioned
Reason may be relevant with the kind of acid used by the pH value of solution and pH adjusting agent, alkali.Therefore sodium benzoate is used to adjust as pH
Joint agent, and use benzoic acid as pH value counter regulation agent, avoiding using the feelings of the cosolvent of other increase clinical practice risks
Under condition, to solve this product easily tiny white point of precipitation, white block, muddy asking of solution under the conditions of long-term storage and winter low temperature
Topic.
