Abstract
The invention discloses a ceftazidime and tazobactam sodium medicine composition liposome injection which comprises the following components in parts by weight: 3 parts of ceftazidime, 1 part of tazobactam sodium, 3-20 parts of liposome membrane material, 2.2-15 parts of additive, 5-20 parts of freeze-drying proppant and 1-3 parts of antioxidant. The ceftazidime and the tazobactam sodium are prepared into liposome, thus the stability of the preparation is greatly improved, the medicine quality is increased, and the toxic and side effects are reduced; and the ceftazidime and tazobactam sodium medicine composition liposome injection has a targeting property, so that the treatment effect is improved.
Description
Technical field
The present invention relates to a kind of ceftazidime and tazobactam sodium medicinal composition liposome injection and method for making thereof, belong to field of medicine preparations.
Background technology
Ceftazidime (Ceftazidime CAZ) has another name called ceftazidime, fortum etc., is semi-synthetic third generation cephalosporin class antibiotic, and antibiotic vigor is stronger, and antimicrobial spectrum is wider, Grain-positive or negative bacterium is all had pretend usefulness.The beta lactamase that gram positive bacteria, negative bacterium are produced has the stability of height; Bacillus pyocyaneus, escherichia coli, klebsiella bacillus, Bacillus proteus, enterococcus, salmonella, shigella dysenteriae, NEISSERIA GONORRHOEAE, Neisseria meningitidis, golden Portugal bacterium, Hemolytic streptococcus, streptococcus pneumoniae and aerobacteria etc. had strong antibacterial activity, particularly for the strongest antibiotic of bacillus pyocyaneus effect.
The antibacterial action mechanism of ceftazidime can suppress the transpeptidation of transpeptidase in the synthetic final step interconnection of cell wall for influencing the synthetic of bacteria cell wall, interconnection can not be formed, thereby it is synthetic to influence cell wall, causes the antibacterial bacteriolyze dead.
Sodium-tazobactam is the novel penicillanic acid sulfones beta-lactamase inhibitor after sulbactam sodium and clavulanic acid, and its structural formula increases a triazole ring on the basis of sulbactam sodium, presses down enzymatic activity to improve.The enzyme effect that presses down of sodium-tazobactam is better than sulbactam; And stability is because clavulanic acid; Especially extended spectrum (ESBLs) being had stronger inhibitory action, is the beta-lactamase inhibitor that market prospect is arranged at present very much, and have toxicity low, press down advantages such as enzymatic activity is strong, good stability.
How ceftazidime and sodium-tazobactam are processed compound formulation at present, can improve the antibacterial activity of ceftazidime greatly, reduce bacterial drug resistance.
This series products ceftazidime and the Tazobactam Sodium sodium injection of existing listing, the ubiquity active constituents of medicine is unstable, and the long-term storage related substance is produced more, and content reduces, and this has not only reduced drug effect, and brings drug risk, the harm patients ' interest.
CN 1418632 A disclose ceftazidime for inj and with the compound preparation of sodium-tazobactam, ceftazidime and with the weight ratio of sodium-tazobactam be 3: 1.Form compound preparation by ceftazidime and sodium-tazobactam by 3: 1 (weight ratio) proportionings.At first prepare sodium-tazobactam; Process mixing suspension by Tazobactam Sodium 150g and water for injection; Add sodium bicarbonate solution adjusting pH value to 6.3 ± 0.1 and obtain the Tazobactam Sodium sodium solution; Obtain the Tazobactam Sodium sodium freeze dry through injection activated carbon decolorizing, degerming filtration, lyophilization, obtain the sodium-tazobactam powder after the pulverizing; With ceftazidime 450g and sodium-tazobactam mix homogeneously, 1000 bottles of packing promptly get ceftazidime and sodium-tazobactam and form compound preparation by 3: 1 (weight ratio) proportionings again.Though the document has disclosed ceftazidime and sodium-tazobactam by the best of breed proportioning on 3: 1 therapeutics meanings, its preparation method causes the stability of its pharmaceutics but to be difficult to satisfy the needs of clinical application.
People's such as Huang Hongqian document " study on the stability of ceftazidime for inj/sodium-tazobactam " is introduced after influence factor's experiment, accelerated tests, long-term experiment; Variations such as ceftazidime for inj/sodium-tazobactam outward appearance, pH value, moisture, content, catabolite prove that the stability of ceftazidime for inj/sodium-tazobactam of the prior art is difficult to accept.
According to the inventor's further research, find existing ceftazidime and sodium-tazobactam by 3: 1 (weight ratio) though the combination very extensive at clinical application, adopt the preparation technology of present prior art to amplify after the production; Still there is muddiness in solution after lyophilized powder redissolves, the underproof phenomenon of visible foreign matters, and also stability of solution is very poor; Require to use up at short notice; Otherwise active component is very easily rotten, causes drug quality to descend, and is inappropriate for injection.
Liposome (Liposome) is dispersed in phospholipid by Britain scholar Bangham and Standlish at first and finds when carrying out electron microscopic observation in the water.Phospholipid is dispersed in the water and forms multilamellar vesicle naturally, every layer of equal bilayer of lipid not; Separated by water between vesicle central authorities and each layer, bilayer thickness is about 4nm.Afterwards, this bimolecular folliculus with similar biofilm structure was called liposome.Liposome can be divided into multilamelar liposome and courage and insight liposome.Unilamelar liposome is divided into small unilamellar vesicle and large unilamellar vesicle again.What Bangham and Standlish found at first is exactly multilamelar liposome, and their are prone to preparation, and size is generally the 0.5-5 micron.Small unilamellar vesicle is spherical, and size is generally the 20-50 nanometer; Large unilamellar vesicle is of a size of the micron number magnitude.People such as Britain Lai Men began liposome is used for pharmaceutical carrier in 1971; The main mechanism of action is that drug powder or solution are wrapped in the aqueous phase that the liposome bilayer lipid membrane sealed or embed in the liposome bilayer lipid membrane; This microgranule type of having cellularity; Get into that principal agent is activated the autoimmune function of body in the human body by reticuloendothelial system phagocytic, and change and distributed in the body of entrapped drug, drug main will be put aside in histoorgans such as liver, spleen, lung and bone marrow; Thereby improve the therapeutic index of medicine, reduce the therapeutic dose and the toxicity that reduces medicine of medicine.Mostly liposome as pharmaceutical carrier is large unilamellar vesicle at present, and particle diameter is generally between the 100-1000 nanometer.
Liposome technology has following advantage as a new medicinal preparation: (1) increases the dissolubility of medicine; (2) toxicity of reduction medicine; (3) give medicine organ targeting property, liver, lung, spleen, lymphoid tissue are had stronger affinity, make the contained medicine of liposome keep high concentration, thereby play the effect of medicine organ targeting property in these internal organs parts; (4) slow releasing function of increase medicine; (5) raising is to the protective effect of medicine.
The present invention is directed to the ceftazidime instability, it is big that the long-term storage related substance becomes, shortcomings such as content reduction, and examination combines ceftazidime and tazobactam sodium with liposome technology, medicine stability and toxic and side effects are had beyond thought effect.
