Lipid micropellet parenteral solution of auspicious bank of Changchun and its preparation method
Technical field
The present invention relates to medical technical field, relate to a kind of Lipid micropellet parenteral solution of auspicious bank of Changchun and its preparation method in particular.
Background technology
Along with the development and the progress of medicine and pharmacology technology, the mankind have controlled the infectious disease that in the past mainly threatens human health basically, then become the archenemy of human health gradually such as noninfectiouss such as tumor, cardiovascular and cerebrovascular diseases.According to 1997 years of World Health Organization (WHO), because of cancer mortality 6,300,000 people are arranged approximately in the whole world 5,800,000,000 populations in 1996, account for 12% of total death toll, wherein nearly 60% dies from pulmonary carcinoma, gastric cancer, breast carcinoma, colorectal carcinoma, oral cancer, hepatocarcinoma, cervical cancer and the esophageal carcinoma, is the second largest cause of the death that is only second to cardiovascular disease.The annual tumor patient of newly making a definite diagnosis in the whole world is all more than 1,030 ten thousand people since 1996, to the end of the year 1999 whole world tumor patient sum exceeded 4,000 ten thousand people.World Health Organization's calendar year 2001 report, world's cancer morbidity and mortality rate have risen 22% than the nineteen ninety, also will rise about 50% in 20 years from now on.The epidemiological study prompting, China not only tumor mortality rate is obvious ascendant trend, and the characteristics that have developing country and developed country spectrum occurred frequently concurrently and deposit, and China increases tumor patient 160-170 ten thousand people newly every year in recent years, and Estimate of Total Number is about 4,500,000 people.Therefore, the exploitation of antitumor drug is the most important thing of many pharmacy worker's researchs.In addition, because most antitumor drug untoward reaction are serious, body and mind to the patient in therapeutic process causes very major injury, therefore how when improving curative effect of medication, improve patient's life quality and become new direction and the emphasis of present antitumor drug research gradually thereby reduce the zest of medicine and toxicity.
Vinorelbine is a kind of semisynthetic vinca anti-cancer agent, the active anticancer height, and antitumor spectra is wide, and through external clinical research, single medicine or drug combination treatment nonsmall-cell lung cancer, breast carcinoma, ovarian cancer, malignant lymphoma etc. have shown outstanding curative effect.But the injection of this medicine has bigger zest when clinical use, such as the vinorelbine tartrate injection of the present clinical use commodity Navelbine by name of company (French Pierre Fabre) is hypertonicity solution, and it is acid that its aqueous solution is, too high or medicinal liquid exosmoses and can produce bigger toxicity to transfusion vein and stimulate as local concentration, and can cause phlebitic generation.Its phlebitis incidence rate 47.2% of research is arranged.Toxicity mainly is that leukocyte count descends overall reaction rate 72%.Therefore the injection that uses clinically at present all requires and must be diluted to 50mL with normal saline earlier, in the short time (6-10 minute), import through vein, use 250-500 mL normal saline flushing vein then, and must confirm that injection needle can start injection at intravenous, in case medicine liquid leakage should stop injection immediately, surplus medicine changes vein in addition and injects.This brings a lot of miseries to the patient undoubtedly, brings a lot of inconvenience on using, and has limited vinorelbine generally popularization and application clinically.
Therefore in view of above-mentioned characteristic, bring into play clinical efficacy better for making vinorelbine, the research and development novel form, cover the zest of medicine with the advantage of novel form, the toxicity that reduces medicine is to give full play to the vinorelbine anti-tumor activity, and this undoubtedly will be significant to further promotion and the application of popularization vinorelbine in clinical.
Lipomul is applied to clinical nearly half a century as the important supply mode of the outer energy of intestinal.Between 1920~nineteen thirty, Japanese scholar was that raw material, lecithin are emulsifying agent with Oleum Ricini once, and at first the synthetic lipomul is tried out in animal; The U.S. has released Lipomul based on cotton seed oil the fifties and has been applied to patient but all fails to promote because of serious toxicity.1964, the U.S. stopped to produce and using lipomul.But in Europe, with Wretling be a collection of scholar of representative to study untiringly and use based on soybean oil, with the lecithin be emulsifying agent, be the lipomul Introlipid of isotonic agent with glycerol.1962, Introlipid was used for clinical in Sweden by official approval.1967, article " lipomul the is applied to complete intravenous nutrition " comprehensive summing up of delivering by Hallberg etc. experiment and the clinical research of Introlipid, prove that it is applied to clinical is safe and reliable, and proposed the criterion of Introlipid clinical practice." obtaining growth, growth and positive nitrogen balance under the long-term complete parenteral nutrition " literary composition that this literary composition and nineteen sixty-eight Dudrick etc. deliver is acknowledged as parenteral nutrition is developed into two pieces of classical works that routine clinical is used significant impact.After this more than 20 year, Introlipid obtained extensive use all over the world, and developed countries such as moral, method, Japan and the United States have developed national lipomul in succession.1976, U.S. appropriate authorities have ratified lipomul again can be in routine clinical application.At present, kind of a lipomul appeared on the market surplus the whole world had 20 at least.China is also joint the end of the eighties and Sweden Kabi company, and mass production Introlipid is for clinical practice.1973, that Solassol etc. have at first introduced is three-in-one, and (All-in-one, the AIO) notion of solution proved that lipomul and all other nutritional solutions can be mixed in the bottle or in the bag, can keep stable and nutritional support effect at certain condition with in the time.After this promoted AIO transfusion plastic bag, the preparation and the infusion of parenteral nutrition liquid simplified in this simple but relevant improvement greatly, for the wide clinical application of lipomul has been widened road.Up to the present, it is oil-in-water type (oil in water, the o/w) submicronized emulsion of emulsifying agent as decentralized photo with the Ovum Gallus domesticus Flavus lecithin that common lipomul is meant with fatty glyceride.Because the Chylomicron that exists behind the composition of lipomul emulsion droplet and particle diameter and the oral fat group food is very similar, therefore it has been generally acknowledged that the emulsion droplet of lipomul is also similar with Chylomicron in the intravital behavior of people in blood.Along with the further investigation to lipomul, it is also just bringing into play more and more important effect at pharmaceutical field.
The special physicochemical property and the hypotoxicity of lipomul have determined it to can be used as fat-soluble medicine, particularly the good carrier of cancer therapy drug, anaesthetic and anti-inflammatory drug.The normal method that adopts is the lipid core part that pharmaceutical pack is wrapped in lipomul because this structure also is similar to microsphere, so lipid microsphere (LipidMicrosphere, title LM) is also arisen at the historic moment.It is generally acknowledged that lipid microsphere is by medicine is dissolved in the fatty oil, and after phospholipid emulsifying is scattered in water, make, be a kind of be soft substrate and the microparticulate system sealed by immobilized artificial membrane with fatty oil, mean diameter is about 200nm.The structural representation of LM is seen accompanying drawing 1.
LM has many physical chemistry and advantage biologically:
1. be the good carrier of fat-soluble medicine.Clinical many medicine poorly water-solubles must rely on the effect of organic solvent competence exertion, and organic solvent not only itself have certain toxicity, also may the interference medicament effect.
2. can effectively increase stability of drug.In the pastille lipid microsphere, quite a few drug distribution is arranged in oil phase or oil-water interfacial film, avoided directly contacting with water.Change responsive medicine for facile hydrolysis or to pH, this " isolation " played the effect that increases stability.
3.LM Chinese medicine partly is wrapped in oil phase or the interfacial film, avoided with body fluid until contacting, thereby reduced issuable part of medicine self and blood vessel irritation.In addition, medicine is by slowly discharge the untoward reaction that can avoid medicine to cause owing to the initial stage excessive concentration in the oil phase when injection in vivo.
4. the small particle of particle diameter about 200 nm can be engulfed by the phagocyte of the reticular tissue system of body and be trapped in the reticular tissue system (as liver, lung etc.), have targeting, this characteristics for antitumor drug improve drug effect, to reduce toxic and side effects particularly important.
We are decided to be encapsulation ratio with the medicine total amount of oil phase and emulsifying agent layer, and assay method is as follows:
(1) the accurate vinorelbine liposome micro ball 100 μ L that draw of the mensuration of medicine total amount add 2mL chromatographically pure ether in the 10mL measuring bottle, add chromatographically pure methanol to scale, mixing, ultrasonic 10min, 0.22 μ m filtering with microporous membrane, get subsequent filtrate, measure, record peak area A with the HPLC method

(3) encapsulation ratio=preparation of Chinese medicine total amount-aqueous phase medication amount
Computing formula is as follows:
Vinorelbine O-I=1-vinorelbine W
Vinorelbine W=(1-W oil) * Cw/CT=(1-W oil) * Aw/AT
Wherein: vinorelbine O-I is the distribution sum of medicine at oil phase and emulsifying agent layer;
Vinorelbine W is the distribution of medicine at aqueous phase;
Cw is the aqueous phase drug level;
CT is the preparation of Chinese medicine total concentration;
W oil is the percentage by weight of oil phase in the preparation.
So, encapsulation ratio=[1-(1-W oil) * Cw/CT] * 100%=[1-(1-W oil) * Aw/AT] and * 100%
