Description

The preparation of injection benflumetol fat milk and the application in malaria treatment thereof
Technical field
The invention belongs to pharmaceutical field, relate to a kind of fat milk injection, particularly a kind of benflumetol fat milk injection and preparation method thereof.
Background technology
Arteannuin is the Chinese scholar a kind of effective malaria monomer that separating-purifying goes out from Herba Artemisiae Annuae in early 1970s, it is the sesquiterpene lactone compound that contains the peroxide bridge structure, have fast, efficient, without Drug resistance, hypotoxic characteristics, be called " maximum for the treatment of malaria is wished " by World Health Organization (WHO), can be considered China pharmacy worker to the maximum contribution of human society.Its discovery becomes world's malaria history another important mileage after quinine.But studies show that, take separately for a long time Arteannuin preparation protozoon is developed immunity to drugs, make compound formulation and arteannuin and other malaria medicine united, also can nearly 95% curative effect be arranged to non-concurrent malaria.Therefore, in February, 2004, WHO reforms malaria treatment medication policy, proposes to stop using artemisine folk prescription antimalarial drug, adopt take artemisinin-based drug as basic combination medicine (Artemisinin-based combination therapies is called for short the ACTs therapy) and advocate.At present, this take artemisinin-based drug as the basis combination medicine mainly contain: Artemether-LUMEFANTRINE, artesunate-amodiaquine, artesunate-sulfamethoxine-pyrimethamine, artesunate-mefloquine, amodiaquine and sulfamethoxine-pyrimethamine drug combinations etc., wherein the effect of Artemether-LUMEFANTRINE drug combination is best.This is because Artemether-LUMEFANTRINE drug combination is can potentiation complementary: the artemisinin derivatives Artemether has stronger killing action to the plasmodium schizont, and is evident in efficacy for multiple resistant malaria and anti-Chloroquine-resistant Falciparum Malaria disease.But it exists again action time short, the shortcomings such as relapse rate height.It is totally thorough that benflumetol is killed plasmodium, and effective percentage reaches more than 95%, and relapse rate is lower than 5%, but onset is slow.So will can overcome simultaneously the high and slow shortcoming of benflumetol effect of Artemether relapse rate behind the two recurrence due to taking drug sides.Have the control symptom fast, kill plasmodium thoroughly, the strain of antagonism worm effectively, the advantage such as delay to develop immunity to drugs.And this compound recipe and existing other antimalarial are without cross tolerance, and be easy to use, safe.This compound oral tablet has obtained the listing approval of U.S. FDA on April 8th, 2009.But at present, the compound recipe dosage form of Artemether and benflumetol only has oral formulations, discloses Artemether/benflumetol compound oral tablet, compound oral syrup, compound suppository etc. such as " number of patent application is 90106722.9 Chinese patent "." number of patent application is 200610037383.5 Chinese patent " discloses the self-emulsifier of Artemether/benflumetol compound recipe." number of patent application is 200710057537.1 Chinese patent " discloses the drop pill of Artemether/benflumetol compound recipe." number of patent application is that 200710057538.6 Chinese patent discloses a kind of preparation method for the treatment of the benflumetol dripping pill of malaria ".These all are peroral dosage forms, when clinical use, can not be used for the emergency treatment of malaria, although they are at the oral administration biaavailability that has improved in varying degrees benflumetol simultaneously, but because the fatty dependency of benflumetol (be the impact that the oral absorption of benflumetol is subjected to food, eat food rich in fat during patient's drug administration, just can have higher drug absorption rate and higher blood drug level to kill the malaria worm) so that benflumetol need to increase the clinical therapeutic efficacy that taking dose and number of times ensure medicine when oral.So benflumetol dosage when clinical use even reaches 2880mg up to 1840mg, taking of so long-term high dose can be accelerated drug-fast generation, thereby greatly shortens the service life of benflumetol, reduces result of use.In addition from patient's angle, high dose, frequently take medicine and increase undoubtedly financial burden, in fact, the high main barrier that has become malaria patients' treatment at present of expense.In order to overcome defects, be necessary to develop the novel form of benflumetol.
Fat milk injection is a kind of new fat-soluble medicine carrier.It is take soybean oil as main component, is emulsifying agent with refined lecithin, and glycerol is isotonic agent, forms through high pressure homogenize.It has good biocompatibility, physical stability high, be convenient to preparation, the characteristic such as safety is good, drug loading is high, be very suitable for injection.Simultaneously, it can also improve malnourished patient's lymphocyte activity, for the patient provides nutrition, is highly suitable for the emergency treatment of subtertian malaria and general malaria.
In sum, in order to protect the clinical service life of benflumetol, improve the bioavailability of benflumetol, the present invention discloses a kind of injection and preparation method of benflumetol fat milk.
Summary of the invention
In order to improve the bioavailability of benflumetol, satisfy the demand that the pernicious treatment malaria of clinical treatment is used for injection, the invention provides a kind of benflumetol injection is the benflumetol lipomul.
Owing to be injection, so its bioavailability is 100%.It need not to add any cosolvent when being used for injection, therefore reduced the incidence rate of toxic and side effects, and it can also improve patient's lymphocyte activity for malaria patients provide health required nutrition, helps the patient to resist malaria and rehabilitation.
