Description
Technical field
The invention belongs to medicine and pharmaceutics field, relate to ciprofloxacin Pharmaceutical composition of a kind of pulmonary administration and preparation method thereof.
Background technology
Ciprofloxacin is third generation carbostyril family antibacterial drugs, the various features such as tool has a broad antifungal spectrum, antimicrbial power are strong, simple in structure, convenient drug administration.It is by acting on the A subunit of DNA of bacteria helicase, suppresses the synthetic of DNA and copies and cause antibacterial death.Ciprofloxacin has broad-spectrum antibacterial action, very strong to the antibacterial activity of gram negative bacteria.Following antibacterial is had to good antibacterial action in vitro: most of antibacterial of enterobacteriaceae, comprises that citrobacter belongs to, the Enterobacters such as cloaca, clostridium perfringen, escherichia coli, Klebsiella, Proteus, Salmonella, Shigella, vibrio and Ye Ersen Pseudomonas etc.Multi-drug resistant bacteria is also had to antibacterial activity, as the Diplococcus gonorrhoeae to Penicillin-resistant, product enzyme hemophilus influenza and Moraxella all have antibacterial activity highly.To most of bacterial strain tool antibacterial actions of the Rhodopseudomonass such as Pseudomonas aeruginosa (bacillus pyocyaneus being commonly called as).The staphylococcus of methicillin-sensitivity is also had to an antibacterial activity, to streptococcus pneumoniae, Hemolytic streptococcus and the medium antibacterial activity of enterococcus faecalis tool.To chlamydia trachomatis, mycoplasma, anti-microbial effect that legionella tool is good, mycobacterium and atypical mycobacteria are also had to antibacterial activity; Poor to the antibacterial activity of anaerobe.
The onset of ciprofloxacin oral administration is slow, drug administration by injection patient poor compliance.And that pulmonary administration has sorbent surface is long-pending large, absorption site blood flow is abundant, avoids the first pass effect of liver,, enzymatic activity is low, and the thinner and membrane permeability high of epithelium barrier, therefore, can reach pulmonary effectively to treat concentration fast, and bioavailability is high.Pulmonary inhalation novel form mainly contains aerosol, spray and powder spray, easy to use, onset feature rapidly that inhalation has.Powder spray, for breathing initiatively, has overcome drug release and has sucked inharmonic problem.
Liposome has following characteristics as the carrier of pulmonary administration: alveolar surfactant is mainly by Lipid composition, and main component is dipalmitoyl phosphatidyl choline.Liposome is to be formed by phospholipid bilayer equally, identical with pulmonary endogenous material, thereby both have good biocompatibility; In topical therapeutic, make that medicine directly acts on target spot, rapid-action, dosage is low, long action time, the medication amount that enters body circulation is few, and side effect is low; Medicine, with after liposomal encapsulated, can reduce drug toxicity, alleviates local excitation and injury of lung after pulmonary administration.
Existing Canadian document discloses the preparation (Desai of a kind of ciprofloxacin liposome for Pulmonary inhalation, T.R.et al.2003.Delivery of liposomes in drypowder form:a erodynamic dispersion properties.Eur.J.Pharm.Sci.20,459-467, Jonathan P.Wong, et al.2003.Liposomedelivery of ciprofloxacin against intracellular Francisellatularensis infection.Journal of Controlled Release.92, 265-273.), after it forms ciprofloxacin liposome by lecithin or dipalmitoyl phosphatidyl choline and cholesterol preparation, the powder that spraying lyophilizing makes mixes with lactose, make pulmonary's Foradil Aerolizer formoterol fumarate or directly ciprofloxacin liposome is made to spray (Lyle G.Sweeney et al.2005.Spray-freeze-dried liposomal ciprofloxacin powder for inhaledaerosol drug deliveryInternational Journal ofPharmaceutics.305, 180-185, Tejas R.Desai et al.2001.Determination of surface free energy of interactive dry powderliposome formulations using capillary penetration technique.Colloids and Surfaces B:Biointerfaces.22,107-113, W.H.Finlay, J.P.Wong, 1998, Regional lung deposition of nebulizediposome-encapsulated iprofloxacin.International Journal ofPharmaceutics.167,121-127.).The liposome that this method makes is stable not, and the seepage of liposome easily occurs, and then affects the quality of the pharmaceutical preparations.
The present invention is by phospholipid material directly being connected to PEG molecule or with PEG molecule coated-liposome, obtaining the liposome of PEGization, to improve the stability of liposome, and prolongation action time.The present invention adds absorption enhancer simultaneously, reduces pulmonary's clearance rate, is beneficial to the pulmonary absorption of ciprofloxacin.
Summary of the invention
One aspect of the present invention relates to a kind of ciprofloxacin Pharmaceutical composition of pulmonary administration, and its liposome of modifying using PEG is as the carrier of ciprofloxacin.Particularly, the liposome that described PEG modifies be PEG molecule by covalent bond the nitrogenous base on phospholipid molecule after being combined, prepare liposome, or be injected in PEG solution and form coated-liposome preparing gained liposome.
In one embodiment of the invention, described PEG is PEG1500, PEG2000 or PEG4000, particularly, is PEG2000.
In one embodiment of the invention, described ciprofloxacin is ciprofloxacin or ciprofloxacin lactate, particularly, is ciprofloxacin.
In one embodiment of the invention, described liposome is the complex that phospholipid or itself and other material are connected to form, described phospholipid is selected from one or more in PC (EPC), dipalmitoyl phosphatidyl choline (DPPC), two nutmeg phosphatidyl cholines (DMPC), two nutmeg acyl phosphatidyl glycerols (DMPG), and described complex is selected from one or more in EPC-PEG, DPPC-PEG, DMPC-PEG, DMPG-PEG.Described other material can be, for example, and cholesterol.The mol ratio of described ciprofloxacin and phospholipid and/or phosphatide complexes is 1/1 to 1/10, particularly, is 1/5.
In one embodiment of the invention, described compositions is aerosol, spray or powder spray, particularly, is powder spray.
In one embodiment of the invention, described compositions also comprises propellant, cosolvent, surfactant, absorption enhancer or excipient.
In one embodiment of the invention, described propellant is tetrafluoroethane (HFA134a) and/or heptafluoro-propane (HFA227), described cosolvent is ethanol and/or propylene glycol, described surfactant is selected from one or more in Tween 80, sorbester p37, oleic acid, phosphatidylcholine, and described absorption enhancer is selected from one or more in sodium cholate, sodium caprylate, Brij 78, rare earth compound Gadolinium trichloride.
In one embodiment of the invention, described excipient is selected from lactose, mannitol, aminoacid or phospholipid, particularly, is lactose, and the mass ratio of described ciprofloxacin and excipient lactose is 1/3 to 1/10, and preferably 1/5.
In one embodiment of the invention, the particle size range of described compositions is 100 μ m to 200 μ m, particularly, is 150 μ m.The present invention is by using nano particle size and Zeta potential and molecular weight analyse instrument to measure the granularity of lactose, and selecting its particle size range is 100 μ m to 200 μ m, and preferably 150 μ m, to reach the demand of lactose as powder spray carrier.
Also aspect of the present invention relates to the preparation method of above-mentioned compositions, comprise by PEG molecule by covalent bond the nitrogenous base on phospholipid molecule after being combined, prepare again liposome, or or be injected in PEG solution and form coated-liposome preparing gained liposome.
The beneficial effect of the invention
