Abstract
A pharmaceutical aerosol composition comprising at least one hydrofluoroalkane propellant; at least one active agent complexed with an adjuvant; and, optionally, at least one pharmaceutically acceptable excipient.
Description
Invention field
The present invention relates to pharmaceutical aerosol composition.Particularly, the present invention relates to stable pharmaceutical aerosol composition, its preparation method is used for the treatment of the application of respiratory disorder (respiratory disorder) with it.
Background and prior art
Metered-dose inhaler (MDIs) be at present the most effectively and the most putative by small dose drug accurate delivery to the instrument of human respiratory.The therapeutic agent generally sent by inhalation route comprises bronchodilator (β-2 agonist and anticholinergic), corticosteroid and antiallergic agent.Sucking also can be for anti-infective, vaccination agent, general action reagent and diagnostic reagent, and the feasible way of anti-leukotriene and protease inhibitor.
MDI comprises pressure vessel, and it is the filling product micronized particle that is such as dissolved in the medicine in liquefied propellant or is suspended in liquefied propellant typically, and wherein said container is equipped with metering valve.Release sub-fraction spray product is allowed in the startup of metering valve, thus liquefied propellant pressure by dissolve or micronized drug particles transport container and arrive patient.Valve actuator is used to guide aerosol spray to enter the oropharynx of patient.
Chlorofluorocarbon (CFCs) has been widely used as the propellant be delivered to via metered-dose inhaler (MDI) in the pharmaceutical preparation of patient.But recent scientific evidence prompting CFC damages earth's ozone layer.Think that the ultraviolet that ozone barrier is harmful to and the loss of ozone layer can cause the generation of skin carcinoma.Result, CFC is now gradually by as the hydrogen fluorohydrocarbon (hydrofluorocarbon) of preferred MDI propellant or HFA (these titles are used interchangeably in this article), and (such as HFA 134a & HFA 227) substitutes.
Propellant HFA 134a, or HFA 134a (these titles are used interchangeably in this article) is nonflammable, has hypotoxicity and have to be suitable for aerocolloidal vapour pressure.But HFA 134a is very bad solvent, under the help not having cosolvent, it can not with valid density is dissolved or fully dispersion is conventional surfactant such as anhydrosorbitol trioleate, dehydrating sorbitol monooleate, lecithin and oleic acid.
Similarly, propellant HFA 227, or HFC-227ea (these titles are used interchangeably in this article) is nonflammable, has hypotoxicity and have to be suitable for aerocolloidal vapour pressure.But the polarity of HFA 227 and dissolubility are different from those of conventional CFC propellant, and many conventional surfactants are soluble or dispersibility is poor in HFA 227.
US5182097 relates to the aerosol preparations be made up of HFA 134a, medicine and oleic acid, described oleic acid as surfactant with the dispersion of ancillary drug in propellant.
US5612053 relates to respirable dry powder formulations, and it comprises the controllable release granule of the adhesive aggregation complex of medicine and carrier, and wherein said carrier is the natural polysaccharide glue added as filler.
EP0384371 discloses aerosol, wherein HFC-227ea or itself and propane, butane, iso-butane, dimethyl ether or 1,1, and the mixture of Difluoroethane serves as propellant.But this application does not disclose suspendible aerosol or pharmaceutical aerosol preparation.
WO93/11747 discloses the medicine mixed suspension preparation being suitable for Aerosol administration, and it is made up of with the propellant being selected from the group be made up of HFA 134a, HFA 227 or its mixture the medicine for the treatment of effective dose substantially.This application specifically discloses the preparation of formoterol fumarate (Formoterol Fumarate) in 1: 1 mixture of HFA 134a, HFA 227 and HFA 134a and HFA 227.Said preparation is not containing surfactant or ethanol.This explanation can regulate the mixture of HFA 134a and HFA 227, to obtain the density of mating with medicine.
WO93/11745 discloses pharmaceutical aerosol preparation, its substantially not containing comprise the surfactant of fluorocarbon or hydrogeneous chlorofluorocarbon propellant and at the most 5% polar co-solvent.Preferred propellant is HFA 134a and HFA 227, and they are preferably used alone.Preferred polar co-solvent is ethanol, and illustrates that the general polar co-solvent of such as 0.05-3.0%w/w in a small amount that only needs is to improve dispersion, and use amount adversely may tend to dissolved substance more than 5%w/w.
The medicinal aerosol formulations of the many HFA of utilization propellants systems is disclosed in, such as, and EP0372777, WO91/11173, and in WO91/14422.The pressurised aerosol preparation being used for drug administration is all paid close attention in these applications.All applications all propose that adding one or more adjuvant such as alcohol, alkane, dimethyl ether, surfactant (comprise and fluoridizing and non-fluorinated surfactants, carboxylic acid, polyethoxylate etc.) and even conventional chlorofluorocarbon propellant is in a small amount intended to minimize potential ozone layer destroying, but still can not determine any beyond thought advantage.
US6303103 discloses a kind of pharmaceutical aerosol preparation, it comprises particulate albuterol (salbutamol) and anticholinergic agents or physiology acceptable salt and solvate thereof, the chlorofluorocarbon propellant of fluorocarbon or hydrogen and substantially not containing or containing the surfactant (by drug weight) being less than 0.0001%.But, about support invention required for protection, not clearly by way of example or any stability study data prove.
Also made great efforts to attempt only with surfactant or substitute to pharmaceutical pack quilt, but result still not very satisfaction.
WO91/04011 describes self-propelled Powder aerosol compositions, it contains that grind, pre-micronized solid drugs, the described solid drugs surface active dispersing agent of the single case where a non-perfluorinated be suspended in aerosol propellant wraps quilt, and described dispersant is substantially insoluble in described aerosol propellant.
PCT/GB2008/002029 describes a kind of preparation comprising tiotropium bromide (tiotropium bromide) with polyvinylpyrrolidone bag quilt.This method for coating has such shortcoming, and namely it needs multiple procedure of processing and spray due to over range and lack uniformity may cause being difficult to amplification scale.
The disclosure of all these patents and patent application is combined in herein all by reference.
The above prior art of major part proposes to use surfactant.But, the use of surfactant may not be feasible to all medicines, because finding suitable suspending agent or dissolving in hydrofluoroalkane (hydrofluoroalkane) and can stablize in the surfactant of drug suspension to have run into a large amount of difficulty.And, described preparation may be made unstable in conjunction with excipient and surfactant in addition.
Due to HFA larger and more moisture absorption than CFC polarity, so find entering of water more significantly in HFAMDI, and polarity, the miscible cosolvent of water, the use of such as alcohol also can make it more serious.Above phenomenon also can be subject to the impact of the character of drug substance or other excipient existed in preparation.The moisture of surrounding is diffused in MDI by valve washer, and by promoting drug particles growth and assembling the physical stability adversely affecting MDI preparation.The gathering of drug particles can block the valve port of aerosol container, thus cause this distributor to work, if or use metering valve, then it can cause inaccurate dosed administration, this can cause undesirable result in the situation of highly effective medicine.Except increase granularity and obstruction valve port, gathering can make suspension physics unstable, and obvious undesirable result, particularly in atomization preparation.
Therefore, still exist providing the method solving the problem that fine drug particles is assembled and the needs providing the stable aerosol composition utilizing hydrogen hydrofluorocarbon propellant.
