Description

Injection butyrate clevidipine composition and preparation method thereof
Technical field
The present invention relates to a kind of butyrate clevidipine composition and preparation method thereof, more particularly to a kind of injection butyric acid Clevidipine emulsion and preparation method thereof.
Background technology
Clevidipine (Clevidipine) belongs to dihydrogen pyridine derivative, is that a kind of calcium used for intravenous injection of ultrashort effect leads to Road blocking agent.Clevidipine has the blood vessel and cardiac muscle selectivity of height, and its is rapid-action, and effect elimination is also fast, can ascending-dose Accurately control blood pressure.
The chemical name of butyrate clevidipine is (±) -4- (2 ', 3 '-dichlorophenyl) -2,6- dimethyl-Isosorbide-5-Nitrae-dihydro pyrroles Pyridine -3,5- dicarboxyl acid methyl (butyryl acyloxy methyl) ester, its molecular formula are C21H23Cl2NO6, molecular weight 456.3, structural formula For:
Butyrate clevidipine is not soluble in water, and the liquid emulsion for being adapted to intravenous injection need to be made.The butyric acid chlorine listed at present The auxiliary material used in dimension Horizon parenteral solution (trade name Cleviprex) for refined soybean oil, refined lecithin, oleic acid, concentrated glycerin, Natrium adetate, sodium hydroxide, water for injection.
Many impurity of butyrate clevidipine are described in patent CN102170786, it can pass through water by clevidipine Solution, decarboxylation and condensation reaction produce.It is using the method for reducing temperature that it, which controls the approach of degradation impurity,.The butyric acid chlorine listed Pointed out in dimension Horizon parenteral solution specification, said preparation must be stored in 2~8 DEG C of refrigerators, but can not be freezed, if room temperature (25 DEG C) can not then refrigerate again after rewarming, and place at ambient temperature, the storage period of said preparation may not exceed 2 months.Butyric acid chlorine The packing specification for tieing up Horizon parenteral solution is 50 and 100ml (0.5mg/ml), so big specification, for transport and storage all It is no small challenge.Nonetheless, referred to (Instructions Page 9) in patent CN102186351, butyric acid chlorine is tieed up under the conditions of 5 ± 3 DEG C In Horizon emulsion the content of hydrolysis impurity be up to 0.5% and the content of decarboxylation impurity be up to 0.4%, illustrate that the product is very unstable It is fixed.
Secondly, to be pointed out in the butyrate clevidipine parenteral solution specification listed, said preparation can not be further diluted, and The dosage of said preparation because injection speed is excessively slow, clinically needs to lead to be per hour 2ml (1mg)~32ml (16mg) The infusion device of fine adjustment dosage " special can " be crossed, with other Large Copacity liquid fit applications, this brings to Clinical practice Very big inconvenience.Patent 201210033558.0 discloses a kind of delivery system, is made up of main preparation and auxiliary emulsion two parts, Main preparation contains medicine organic solution, and auxiliary emulsion is the blank emulsion of not drug containing, is administered after mixing.Patent 201210054616.2 disclose a kind of Clevidipine butyrate injection, including medicine, oil, phosphatide and organic solvent, during use Become emulsion after dilution.Above two mode all using add organic solvent mode, and organic solvent all have compare Big excitant, therefore, safety risks still be present.
Patent 201210595653.X has been made into lyophilized breast, adds its stability, has been also convenient for clinical injection, its It is prepared by the supplementary material of following weight proportion:0.01~1.2 part of butyrate clevidipine, glycerine 10-50 parts, acidity regulator In right amount, stabilizer 0.01-1.2 parts, freeze drying protectant 30-100 parts, oil for injection 80-130 parts, aqueous phase surfactant 0.1- 15 parts, oil phase surfactant 0.1-15 parts, water for injection adds to 1000 parts.In its aqueous phase surfactant used, tween All there is certain excitant with poloxamer, moreover, after adding glycerine in prescription, sample easily collapses in freeze-drying process, The envelop rate of medicine declines after more seriously redissolving, and causes the seepage of medicine to increase.
Therefore, the prescription that we freeze breast to butyrate clevidipine has carried out bold improvement, the work of aqueous phase surface is eliminated Property agent, and use oil phase coemulsifier instead, emulsifying effectiveness is not only ensure that, more improves security;Glycerine is eliminated, is added The operability of freeze-drying prods, meanwhile, it is found surprisingly that, improves the envelop rate of product, reduces the seepage of medicine.
The content of the invention
The technical problems to be solved by the invention are to overcome the defect of prior art, there is provided a kind of injection butyric acid chlorine dimension ground Flat breast and preparation method thereof.
Technical scheme is as follows:
A kind of injection butyrate clevidipine composition, is made up of, butyrate clevidipine the supplementary material of following weight proportion 25-50 parts, oil for injection 100-1000 parts, egg yolk lecithin 6-180 parts, oleic acid 0.3-9 parts, natrium adetate 0.05-5 parts, 50~4000 parts of freeze drying protectant.
Described oil for injection be selected from refined soybean oil, peanut oil, safflower oil, cottonseed oil, olive oil, coconut oil, sesame oil, Fish oil, medium chain mono, medium chain triglyceride dibasic acid esters, medium chain triglyceride, ethyl oleate, acetylated monoglyceride, propane diols are double In ester, glyceryl linoleate, polyethylene glycol glyceryl laurate ester or it is combined.Preferably exquisite soybean oil and medium chain triglyceride Combination, both weight ratios be 1:1.
Described freeze drying protectant is selected from lactose, sucrose, trehalose, dextran or its combination.
The present invention provides a kind of preparation method of injection butyrate clevidipine composition, comprises the following steps:
(1) preparation of oil phase:Egg yolk lecithin, oleic acid and butyrate clevidipine are separately added into oil for injection, stirring makes It dissolves, as oil phase;
