Description
Technical field
The present invention relates to a kind of imbedibility liquid preparation and preparation method thereof, be specifically related to a kind of non-organic solvent system
Standby sinomenine hydrochloride is imbedibility liquid preparation of raw material and preparation method thereof.
Background technology
Sinomenine is from menispermaceous plants Caulis Sinomenii Sinomenium acutum the earliest by Ishiwari etc.
(Thunb.) rhizome of Rehd.et Wils. is separated, have antiinflammatory, immunosuppressant, analgesia, blood pressure lowering,
The pharmacological actions such as arrhythmia.
In Caulis Sinomenii, main component is alkaloid, and the composition having now been found that has sinomenine (Sinomenine), different green grass or young crops
Rattan alkali (Igoginomenine), China's sinomenine (SinoAcutine), short Sinomenium acutum time alkali (Acutumidine), point sinomenine
And disinomenine (Diginomenine), ethyl sinomenine (ethylsinomenine), four hydrogen meter Radix Berberidis Amurensis (Sinaetine)
Alkali (sinactine), tetrahydrochysene epiberberine, Caulis menispermi ripple phenol alkali, bianfugenine, Tetrahydropalmatine etc..
At present commercial production sinomenine hydrochloride uses alkalization water extraction process, its be in Caulis Sinomenii addition water and
A certain amount of Calx, alkalizes a period of time, is subsequently adding a certain amount of technical benzene, reflux, extract, in water-bath,
Rear acidifying, standing, crystallize.Also document report is had to introduce extraction and the purification process of sinomenine, the dilute sulfur of Caulis Sinomenii
Acid percolate, adjusts pH value 9 with lime water, and benzene carries out counter-current extraction at 50 DEG C, and benzene extraction liquid is carried out with 1% hydrochloric acid
Anticountra flow extracts, activated carbon decolorizing, and crystallization carries out recrystallization in the hot water, obtains sterling.(Chen Yukun " Chinese medicine
Extraction process ", 1992)
This several method all uses benzene that toxicity is the biggest as Extraction solvent, and benzene is one-level toxic solvent, in pharmacy
Industry is the most disabled, and need to can be only achieved environmental protection by the most cumbersome technique in terms of the recycling of solvent and want
Ask, and chloroform is two grades of toxic solvents, thus should avoid using benzene and chloroform solvent in Chinese medicine extraction as far as possible.
Fog inhalation therapy is, with atomising device, atomization preparation such as imbedibility liquid preparation is dispersed into small droplet
Or microgranule so that it is it is suspended in gas in entrance respiratory tract and lung, reaches quickly to absorb and the purpose of local treatment.

Experimental example 5: optimization
The prescription of imbedibility liquid preparation generally uses injection water as solvent, add if desired a small amount of ethanol or
Propylene glycol.Adjuvant includes HCl, NaOH, tartaric acid, NaCl etc..For increasing medicine stability, it is also possible to
Add sodium sulfite or EDTA.
Sinomenine hydrochloride is soluble in water, it is not necessary to add cosolvent.But sinomenine hydrochloride easily aoxidizes, PH is too high i.e.
Sinomenine can be made to decompose.Therefore, the pH value of imbedibility liquid preparation should be maintained between 3～4, and adds Asia
Sodium bisulfate and disodium edetate stabilizer are to ensure the stability of medicine.
1.1 deposition ratio in the effective position measure
Imbedibility liquid preparation means one or more medicine, through special doser, enters and breathes
Road deep lung, plays a kind of drug-supplying system locally or systemically acted on.Drug particle in imbedibility liquid agent should
The finest (0.5～5 μm), can arrive site of action, but nonetheless, the most only medicine of 1%～20%
Can deposit in effective site, play curative effect.Therefore, British Pharmacopoeia, American Pharmacopeia and Chinese Pharmacopoeia all specify needs
The deposition ratio in the effective position of imbedibility liquid preparation is measured.
1.1.1 instrument and equipment and operation
Using imitated TI device, see Fig. 1,1. rubber interface uses rubber stopper, selects not according to suction apparatus
Same interface.2. plastic screw cap: need mold to prepare, do not satisfy the requirements, easily causes when using rubber stopper
Device is not parallel, tests poor reproducibility, therefore will use glass frit seal herein.3. small size polypropylene filter is used
The transformation of the way, connects with vertical tube at H with latex tubing.4. trunnion is simulated: be first at round-bottomed flask and vertical tube c
Level (stage I), is equivalent to main bronchus；Conical flask and bend pipe E, be the second level (stage II) at vertical tube H,
Be equivalent to lung bronchioles with lower portion, i.e. effective site.
Operational approach: 1. device such as figure, should ensure that two vertical tubes are parallel.2. place at first order round-bottomed flask
Acceptable solution 7ml, places acceptable solution 30ml at the conical flask of the second level, acceptable solution kind is relevant with given the test agent.
3. regulate the height of G, make just to contact with bottom conical flask at the protrusion of center.4. vacuum pump is connect, speed of bleeding
Degree is adjusted to 60L min-1, it is ensured that the medicine of unit dose discharges completely.5. with blank acceptable solution by bend pipe E and
Medicament elution at vertical tube, and close with the acceptable solution in conical flask, measure the content of medicine, calculate medicine and exist
Deposition percentage rate at the second level.

nullB、Upper prop eluting: by good cation exchange resin processed on percolate or 152 type resins，Blade diameter length ratio is 1:10，Loading speed be 3 times of column volumes/hour，Precipitation is had to effluent silico-tungstic acid test solution inspection，And stop loading during thin layer chromatography detection inanimate object alkaline spot point，It is eluted to eluent without stopping during color by purified water，With 8～15% ammonia solution soak resin or 3～10% hydrochloric acid solution soak 152 type resin 12 hours，Again with the ammonia that pH value is 11-ethanol solution eluting or 152 type resins, 6% hydrochloric acid solution eluting，Elution speed is 2-5BV/h，Eluent silico-tungstic acid test solution inspection receives when having precipitation，Receive when eluent silico-tungstic acid test solution checks without precipitation and stop，Merge eluent，Being neutralized to PH with hydrochloric acid or ammonia is 8，Desalination，Concentrate drying，Obtain sinomenine hydrochloride crude product.
C, refined: to remove sinomenine hydrochloride crude product 7 weight portion, 95% ethanol or purified water with 60ml are heated to reflux to being completely dissolved, add the activated carbon of 4% times of weight, insulation backflow 20 minutes, filters while hot, and filtrate concentrates, cooling, crystallize, filtering, it is colourless to filter cake that the ethanol solution with 80% cleans filter cake, obtains sinomenine hydrochloride.
6. the preparation method of the imbedibility liquid preparation as described in claim 1-4 is arbitrary, it is characterised in that the method is:
Take appropriate water for injection, nitrogen charging, add recipe quantity sinomenine hydrochloride and be stirred to dissolve；Add sodium sulfite, disodium edetate, sodium chloride are stirred to dissolve, and continue nitrogen charging, add 0.10～the activated carbon of 0.20%, and 35～45 DEG C are incubated 10 minutes, filter carbon removal, add water for injection to 1000 parts by volume, inspection, fine straining is to clear and bright, nitrogen charging embedding, 100 DEG C of sterilizings 30 minutes, to obtain final product.
7. the application in the medicine of preparation treatment pharyngolaryngitis, rheumatoid arthritis, chronic nephritis or interstitial pulmonary fibrosis of the imbedibility liquid preparation as described in claim 1-4 is arbitrary.
8. the imbedibility liquid preparation as claimed in claim 5 application in the medicine of preparation treatment rheumatoid pharyngolaryngitis, arthritis, chronic nephritis or interstitial pulmonary fibrosis.
