A kind of injection anidulafungin redissolves medicament and preparation method thereof
Fields
The invention belongs to technical field of medicine, and in particular to a kind of injection anidulafungin redissolves medicament and its preparation
Method.
Background technique
Echinocandin is the inhibitor of fungal cell wall biosynthesis.Its synthesis by destroying 1,3- callose
It plays a role.Anidulafungin (anidulafungin) is the semi-synthetic antifungal of third generation echinocandin class, is echinocandin
The derivative of B is docked by the echinocandin B generated from aspergillus nidulans with the side chain synthesized.
Its molecular structural formula is as follows:
Injection anidulafungin is the Injectable sterile freeze-dried powder of anidulafungin, is developed by Vicuron drugmaker, the U.S.,
In December, 2006 in U.S.'s Initial Public Offering, trade name ERAXIS, anidulafungin does not list at home at present.
Anidulafungin is not soluble in water, is slightly soluble in ethyl alcohol, and the redissolution of anidulafungin is larger problem after freeze-drying, and ERAXIS was once
The use of 20% sterile ethanol solution is to redissolve solvent, rapidly, but ethyl alcohol increases the adverse reaction of patient for dissolution, after change
For the sterile water for injection of same volume, although reducing adverse reaction, dissolution is slack-off, and the redissolution time extends to 5 minutes,
Particulate matter in medical fluid be above standard possibility increase, and redissolve overlong time, equally increase the risk of microbiological contamination, institute
It is needed with developing the injection anidulafungin for being easy to redissolve.Chinese patent application CN12345229A discloses a kind of spine
The prescription of the freeze-dried powder of white rhzomorph, the freeze-dried powder that its echinocandin is mentioned in background of invention was usually redissolved at 1 minute, but was not said
The conditions such as the bright redissolution solvent used.Chinese patent application CN106860856A discloses a kind of prescription of injection anidulafungin
And preparation process, but the data of redissolution are not mentioned.
In conclusion anidulafungin is insoluble in water, it is sterile water for injection that injection anidulafungin, which redissolves solvent, at present,
Redissolve that situation is simultaneously unstable, addition 3ml sterile water for injection dissolves that form anidulafungin dense in the anidulafungin of usual every 10mg
Degree be about 3.33mg/mL solution, dissolve it is slower, can make the particulate matter in medical fluid be above standard possibility increase, and
Time extension is redissolved, the risk of microbiological contamination is equally increased.
Summary of the invention
For the above the deficiencies in the prior art, the purpose of the present invention is to provide a kind of injection anidulafungins to redissolve medicament
And preparation method thereof.Injection anidulafungin provided by the invention redissolves medicament and preparation method thereof, from the redissolution medicament of drug
And lyophilized technique is set about, and by many experiments, is surprised to find that injection anidulafungin prepared by the present invention redissolves answering for medicament
The molten time is obviously shortened, and for particulate matter well below limit value, sample is placed in (sample storage temperature under 25 DEG C of acceleration environments
It is 2~8 DEG C) 6 months, the redissolution time still conforms to require with effect is redissolved.
Technical scheme is as follows:
A kind of injection anidulafungin redissolution medicament, including following component and mass fraction:
45~55 parts of anidulafungin, 45~55 parts of fructose, 220~280 parts of mannitol, 5~7 parts of tartaric acid, cosolvent 150
~200 parts, 2~3.7 parts of pH adjusting agent.
Further, the injection anidulafungin redissolves medicament, including following component and mass fraction:
50 parts of anidulafungin, 50 parts of fructose, 250 parts of mannitol, 5.6 parts of tartaric acid, 175 parts of cosolvent, pH adjusting agent 2.6
Part.
Further, the cosolvent is by polyoxyethylene sorbitan monoleate and polyoxyethylene hydrogenated castor oil 60 8~11:4 in mass ratio
Composition.
Further, the cosolvent is by polyoxyethylene sorbitan monoleate and polyoxyethylene hydrogenated castor oil 60 10:4 group in mass ratio
At.
Further, the pH adjusting agent is sodium hydroxide.
The injection anidulafungin redissolves the preparation process of medicament, comprises the following steps:
S1, match liquid: tartaric acid, fructose, mannitol, cosolvent being added in the water for injection that quality is 5~10 times and dissolved,
Adjusting pH with pH adjusting agent is 4.0~5.5, and temperature remains 10~15 DEG C, and anidulafungin, which is added, to be made to dissolve, and obtains mixed raw material
Liquid A;
S2, water for injection of the quality in step S1 20~40% will be added in mixed raw material liquid A made from step S1,
Temperature remains 10~15 DEG C, is uniformly mixed, obtains mixed raw material liquid B;
S3, it removes endotoxin: active carbon being added into the mixed raw material liquid B that step S2 is obtained and stirs 30min, filtering obtains
Mixed raw material liquid C;
S4, degerming: it is filling in cillin bottle by the degerming membrane filtration degerming of mixed raw material liquid C made from step S3, often
Bottle 5mL;
S5, freeze-drying:
1) pre-freeze: the canned cillin bottle of step S4 is placed on drying box shelf, baffle temperature is reduced to -10~-5
DEG C, 10~30min is kept, baffle temperature is down to -50~-45 DEG C in 20~30min, keeps 1~3h, baffle temperature liter
Temperature keeps 1~2h to -35~-30 DEG C, then temperature is down to -55~-50 DEG C, keeps 2~3h, obtains pre- agar;
2) the pre- agar for obtaining step 1) pre-freeze carries out dry for the first time: drying box vacuum degree is 10~20Pa, partition
