Description

The method of macrolide formulations that is used to suck and treatment endobronchial infections
Invention field
The present invention relates to be used for by sucking the macrolide formulations that transmission is novel and improve, for example erythromycylamine preparation and treatment susceptibility are acute or the interior modification method that infects of chronic bronchial.Specifically, the present invention relates to preparation, it contains at least a spissated macrolide antibiotic in the acceptable solution of physiology or with dry powder form.Preparation is fit to the macrolide antibiotic medicine to pulmonary branches endotracheal airway space transmit fluid aerosol or dry powder aerosol form, erythromycylamine for example, wherein the major part of aerosol droplets or preparation granules have the quality meta aerodynamic diameter between the 1-5 micron.The effective dose of macrolide preparation and aerosol transmission can effectively treat and/or prevent acute and interior infection of chronic bronchial and pneumonia, and particularly those are because streptococcus pneumoniae (5treptococcus pneumoniae), Haemophilus influenzae (Haemophilus influenzae), staphylococcus aureus (Staphylococcus aureus), morazella catarrhalis (Moraxellacatarrhalis), pneumonia legionella (Legionella pneumophia), Chlamydia pneumoniae (Chlamydiapneumoniae), and mycoplasma pneumoniae (Mycoplasma pneumoniae) causes.The novel formulation volume is little, but the macrolide antibiotic of effective dose can be delivered to sites of infection.In others, the present invention relates to macrolide list agent formulation novel and improvement, transmit to suck by aerosol.
Background of invention
Streptococcus pneumoniae and other typical case and atypical pathogenic infection suffer from the interior space of bronchus [S.Chodosh etc., the Clinical Infectious Diseases1998 of the individual lung of chronic obstructive disease of lung (COPD); 27:730-738].COPD is modal to be chronic bronchitis (CB) and emphysema.
Chronic bronchitis is a kind of pulmonary disease, it is characterized in that lung tissue inflammation and carrying out property destruction.The weakness of lung is assembled relevant with the interior purulent sputum that causes producing that infects of the chronic bronchial that amount of expectoration increases and impaired pulmonary function causes that produces chronic cough, every day among patient CB.The feature of the acute exacerbation of chronic bronchitis (AECB) is generally the increased coughing, produces the clinical decline that purulent sputum and streptococcus pneumoniae, Haemophilus influenzae and morazella catarrhalis cause.Pneumonia also may be because these biologies cause once more or as the syndrome of COPD is infected.Though for CB, particularly whether the antibacterial therapy of CB acute exacerbation treatment suitably has arguement, (JAMA 1995 for Saint etc.; 273:957-960) proof is not when when treating comparison, and the oral cavity antibacterial therapy provides some clinical benefits.In addition, the dosage of antibacterial is important for recurrence time.Therefore, oral cavity antibacterial dosage is high more, does not have interval long more (S.Chodosh etc., the Clinical Infectious Diseases 1998 of medium infection; 27:730-738).
At present, oral administration is for the selected Therapeutic Method of CB for typical case and the activated macrolide of atypia pathogen and fluoroquinolone.Yet the oral administration of macrolide antibiotic has adverse side effect.The modal side effect relevant with oral cavity/parenteral macrolide antibiotic treatment is diarrhoea/forfeiture appetite, feels sick, suffers from abdominal pain and vomiting (R.N.Brogden, D.Peters, Drugs, 1994; 48:599-616 and H.D.Langtry, R.N.Brogden Drugs 1997; 53:973-1004 and the document of wherein quoting).In addition, pseudomembranous colitis is and the oral cavity antibiotic therapy, comprise the relevant serious side effects of oral cavity macrolide treatment (S.H.Anmad etc., Indian J.Pediatr.1993,60:591-594).Macrolide infiltrates lung tissue along with dosage and change of component (R.N.Brogden, D.Peters, Drugs, 1994 behind the oral administration; 48:599-616 and H.D.Langtry, R.N.Brogden Drugs 1997; 53:973-1004 and the document of wherein quoting).In addition, macrolide nothing to do with medicine, for example the change of theophylline systemic concentration is relevant, this be because with the interaction of liver based on the metabolic system of cytochrome.This drug-drug interactions usually needs dosage to regulate or remove a kind of composition from therapeutic scheme.
Erythromycylamine is 14 yuan of ring macrolide, belongs to antibiotic erythromycin family, has similar antibioticogram external to Erythromycin A, and is similar with Erythromycin A, is effective Therapeutic Method of typical and atypical pneumonia.Erythromycylamine has the C-9 amino functional of S-configuration, replaces the C-9 carbonyl of finding in Erythromycin A.A critical limitation of erythromycylamine is that it lacks buccal absorption, therefore in order to realize useful treatment concentration, exploitation prodrug dirithromycin.The prodrug of erythromycylamine is a dirithromycin, it is characterized in that having between C-9 amino and C-11 hydroxyl the acetaldehyde functional group (see figure 1) of bridging.Cyclic acetaldehyde passes through the rapid hydrolysis of non-enzymatic process (about 30 minutes of half-life) in blood plasma.Dirithromycin has shown can successfully treat deterioration (M.Cazzola etc., the Respiratory Medicine that takes place among patient CB; 1998; 92:895-901).(30-44 hour) (R.N.Brogden, D.Peters, Drugs, 1994 long half-lift that the major advantage of erythromycylamine being it; 48:599-616).Unfortunately, the oral cavity usability of dirithromycin 10-14% only in the people most ofly discharges (62-81%) as erythromycylamine at the feces camber.Because erythromycylamine is not absorbed, its prodrug dirithromycin absorbs seldom, and the active drug substance amount that pulmonary infection general typical for treatment and that the atypia antibacterial causes can get seldom.Though this sites of infection has enough erythromycylamine concentration so that curative effect to be provided, drug concentrations is limited.Oral cavity dosage is high more, or the frequent more drug level that improves action site of dirithromycin administration; Yet, easier generation adverse events, and can increase working hard and adaptation of patient.
Reported antibiotic one of the research the earliest of the use solation that is used for the treatment of pulmonary infection among the Lancet 22:1377-9 (1981).Controlled double-blind study for 20 patients CF shows that the aerosol administration of Carbenicillin and glucosamine gentamycin can improve patient's CF health.From then on, dispersive report has detected general aminoglycoside aerosol transmission, particularly tobramycin (seeing for example U.S. Patent number 5,580,269) in the document.Yet the assessment of these researchs and difficult is because antibiotic formulations, breathing technique, aerosol apparatus and compressor are different.In addition, the aerosol transmission is difficult to assessment usually, because differences such as preparation, aerosol transfer device, dosage, granular size, therapies.When for example quality meta aerodynamic diameter (MMAD) is greater than 5 microns, granule is deposited in the upper respiratory tract usually, has reduced the amount that is delivered to the sites of infection in the lower respiratory tract.Arch.Dis.Child., the article of publishing among the 68:788 (1993) has been described the needs of standard method emphatically and to the improvement of patient's CF aerosol-applied medicine.
Because shortage is additive-free and the physiology goes up compatible preparation, particularly granular size homogeneous has been damaged effective aerosol administration at present because some aerosol apparatus can not produce little.With drug delivery space and lung on every side in the bronchus, the particle size range of the aerosol particle that sites of infection is required is about 1-5 micron.Many aerosolized therapeutic agents, the aerosol apparatus that comprises aminoglycoside produce a large amount of particle diameters less than 1 micron or greater than 5 microns aerosol particle.For effective treatment, most of aerosolized particles containing antibotics can not have the MMAD greater than 5 microns.When aerosol contained a large amount of MMAD greater than 5 microns granule, the granule of greater particle size was deposited in the upper respiratory tract, has reduced the antibiotic amount of the sites of infection that is delivered to lower respiratory tract.
The commercially available aerosol apparatus of present three classes, jet nebulizer, vibration porous plate aerosol apparatus and ultrasonic nebulizer can produce and transmit the aerosol particle of diameter between the 1-5 micron, and this particle diameter is preferred for the bacterial infection treatment of lung.Therefore, can in injection, vibration porous plate and ultrasonic nebulizer, effective aerosolized macrolide formulations be very favorable for providing.In addition, newer aerosol generating technique can get at present, comprises that machinery is extruded and passive and energy supply Diskus, is used to transmit the therapeutic agent of dry powder form.
Another requirement of acceptable preparation is suitable storage life.Usually, the antibiotic solution of antibiotic and specific intravenously administrable contains phenol or other antiseptic, to keep drug effect and the generation of catabolite is minimized.Yet phenol and other antiseptic can be induced bronchospasm when aerosolized, and a kind of suffering from pneumonopathy, for example bad incident among the patient of chronic bronchitis.
Use macrolide antibiotic, erythromycylamine for example, be used to suck the aerosol of liquid or dry powder form, have and overcome the weak oral cavity biological utilisation relevant, simultaneously lung is provided the advantage of the antibiotic valid density that can not realize by oral cavity or intravenous route with prodrug.It is its natural high-affinity and persistency in the blood plasma compartment (long blood plasma/organize the half-life) for lung tissue that the erythromycylamine aerosol transmits another advantage.Endobronchial infections can be eliminated or reduce significantly to the transmission of high concentration aerosol, long blood plasma/organize the combination of half-life and high lung affinity will make the macrolide treatment safer after using single agent aerosol.
Therefore, very advantageously provide the macrolide antibiotic preparation, erythromycylamine for example, it does not contain antiseptic, is adjusted to the pH level that slows down or prevent to degrade, and for patient's tolerance, provide be fit to commercially to distribute, storage and suitable half-life of using.
Therefore, an object of the present invention is to provide macrolide antibiotic, the concentrate formulation of erythromycylamine, Erythromycin A, Roxithromycin, Azithromycin and clarithromycin for example, it contains can be by spraying, for example by using injection, vibration porous plate or ultrasonic nebulizer or Diskus effectively aerosolized, become the macrolide antibiotic of valid density of the form of aerosol particle, this aerosol particle particle diameter is mainly between the 1-5 micron.

The pH of preparation transmits no less important for aerosol.As before noticing, when aerosol when being acid or alkaline, it can cause bronchospasm and cough.The safety range of pH is relative; Some patients will tolerate the tart aerosol of appropriateness, and will cause bronchospasm in other people.Any aerosol that has in the susceptibility individuality less than 4.5 pH will cause bronchospasm; Aerosol with the pH between the 4.5-5.0 can cause this problem once in a while.The aerosol of pH between 5.0-7.0 is considered to safe.Avoid pH greater than any aerosol of 10.0, because can cause the stimulation of bronchospasm.The best pH of aerosol preparations is pH5.0-7.0.
In one aspect, the preferred main atomization of liquid preparation of the present invention becomes granule, and this granule can be with end and alveolar bronchiole and the lower respiratory tract of drug delivery to the antibacterial place.In order effectively erythromycylamine to be delivered to pulmonary branches endotracheal airway space by aerosol, the essential aerosol particle of quality meta aerodynamic diameter between the 1-5 micron that form.Be used for the treatment of and prevent endobronchial infections, particularly because the preparation and the transmission capacity of the erythromycylamine of the infection that antibacterial streptococcus pneumoniae, Haemophilus influenzae, staphylococcus aureus, morazella catarrhalis, pneumonia legionella, Chlamydia pneumoniae and mycoplasma pneumoniae cause must be effectively at the bronchus inner surfacies.The formulation dosage of transmitting preferably has minimum actual aerosolized volume, the erythromycylamine of effective dose can be delivered to sites of infection.Preferred preparation also provides the condition that does not influence the airway function.Therefore, preferred formulation contains the medicine of capacity, is allowing its effective transmission, avoids simultaneously preparing under the condition of untoward reaction.Novel formulation of the present invention meets these requirements.
According to the present invention, erythromycylamine is mixed with the dosage form that the patient who is used for chronic bronchitis and pneumonia sucks treatment.Because patient is found everywhere through the world, and needs preparation that rational long shelf life can be arranged.Storage condition and preparation stability thereby become important.
As mentioned above, the pH of solution is important.5.0-7.0 preferred about 6.0 pH is best for storage and long shelf life.
Preparation is stored in 1 milliliter of-2 milliliters of low density polyethylene (LDPE) (LDPE) vial usually.With blowing-fill-the aseptic filling vial of seal process.Seal vial with aluminium foil bag.
Preparation is another very important condition for the stability of oxidation.If medicine is degraded before aerosolized, small amount of drug is passed to lung, and therefore infringement is treated and caused the condition that may cause for the generation of erythromycylamine resistance, because the dosage that transmits very little.In addition, the erythromycylamine catabolite can cause bronchospasm and cough.For the oxidative degradation that prevents erythromycylamine with acceptable stability is provided,, produce product with low oxygen content by the LDPE vial being packaged in the oxygen protective package (comprising aluminium foil bag, 6 every bag).Before the vial filling, the solution in the blending tank leads to nitrogen, and the ring bag head is eliminated nitrogen.With this method, prevent the hydrolysis and the oxidation of erythromycylamine.
II. aerosolized device
The aerosolized device that is used for the present invention's practice for example sprays, vibrates porous plate or ultrasonic nebulizer and preparation spraying of the present invention can be formed aerosol particle usually, and it mainly is a 1-5 micron size.In this application, mainly be meant at least 70%, but the aerosol particle of preferred all generations more than 90% is in the 1-5 micrometer range.
Can produce and transmit size particles between the 1-5 micron, aerosol apparatus for treatment streptococcus pneumoniae, Haemophilus influenzae, staphylococcus aureus, morazella catarrhalis, pneumonia legionella, Chlamydia pneumoniae and mycoplasma pneumoniae infection the best, for example spray, ultrasonic, vibration porous plate and fill can the dry powder inhaler, can buy at present, or with known method and material production.The running of jet nebulizer is by air pressure solution to be broken into aerosol droplets.The running of vibration porous plate aerosol apparatus is the ultrasonic vacuum that produces by the porous plate that uses rapid vibration, so that solvent droplets is pushed through porous plate.The running of ultrasonic nebulizer is by piezoquartz, and it becomes little aerosol droplets with liquid shear.Yet only the preparation of some erythromycylamines can be effectively by these three kinds of atomizer spray, because these pH and the ionic strengths of installing for preparation are responsive.
Though can use various devices, only the aerosol apparatus of limited quantity is applicable to the present invention.Be used for preferred aerosol apparatus of the present invention and comprise for example AeroNeb TMAnd AeroDose TMVibration porous plate aerosol apparatus (AeroGen, Inc., Sunnyvale, California), the Sidestream aerosol apparatus (Medic-Aid Ltd., West Sussex, England), Pari LC Plus With Pari LC Star Jet nebulizer (Pari RespiratoryEquipment, Inc., Richmond, Virginia) and Aerosonic TM(DeVilbiss MedizinischeProdukte (Deutschland) GmbH, Heiden, Germany) and UltraAire (OmronHealthcare, Inc., Vernon Hills, Illinois) ultrasonic nebulizer.
III. aerosol pharmacokinetics
By IV and inhalation route rat is used erythromycylamine solution, measure the drug level in blood plasma and the lung.The data of these researchs are shown in Fig. 8 and 9.Select two kinds of dosage levels for sucking pipeline, 1.7 and 0.7mg/kg, with single vein dosage (25mg/kg) relatively.
The dosage demarcation AUC of erythromycylamine is respectively 24.21,1067.84 and 848.34 μ gh/g in IV (25mg/kg), suction (1.7mg/kg) and the lung (0.7mg/kg).Therefore, directly lung is transmitted erythromycylamine by inhalation route, the lung levels of drugs that reaches on the microgram level than high about 40 times of intravenous route administration.Therefore, should be more effective by sucking antibiotic therapy than oral cavity or the treatment of IV approach.
IV. aerosol is renderd a service
Erythromycylamine vein and aerosol administration are all very effective.At the lowest dose level (10mg/kg every day) of test intravenous use erythromycylamine and make the lung burden of streptococcus pneumoniae drop to (the every gram lung of 10CFU/) but below the detectable limit, shown in embodiment 7.Aerosol also is very effective (see figure 10), with 5mg/ml (calculating dosage 0.13mg/kg every day) aerosol solution streptococcus pneumoniae detectable recovery is only arranged.In addition, when with the concentration when using 3 days greater than required dosage every day, erythromycylamine is very effective.0.13mg/kg single dose (CFU/ gram reduce be no more than 2 orders of magnitude) poorer slightly than 3 days effects of 0.13mg/kg (declines of 5 orders of magnitude) continuous administration.Yet single agent 0.67mg/kg realizes almost completely removing this microorganism from lung tissue, and is similar to the multi-agent effect, shows that in this concentration second and three dose does not almost have extra value (seeing Figure 11).
The pharmacokinetics assessment prompting of aerosolized erythromycylamine, its valid data show, the lung concentration suitable with multi-agent IV every day, oral cavity or aerosol dose can realize that the about 3-5 of dosage that single agent should be more required than the similar effect of three daily doses doubly by single agent aerosol.
Practicality
An aspect of practicality of the present invention is to use the macrolide antibiotic of small size high concentration, for example erythromycylamine preparation and suitable aerosol apparatus, the erythromycylamine of effective dose passed to suffer with chronic bronchitis, space in the people's of bronchiectasis and pneumonia the bronchus, these diseases cause owing to macrolide susceptibility antibacterial or other infection.Preparation safety and cost are very cheap.In addition, preparation can be deposited in the nitrogen environment, and control pH is with tolerance, so that the commercial suitable shelf life that distributes to be provided.
