Background of the invention
The present invention relates to new compounds, including:
3,5-diamino-N-(N-(4-(4-((S)-2-amino-3-(4-(3-(bis((2S,3R,4R,5R))-

Carboxamide and related compounds and their pharmaceutically accepted salts are useful in the form of sodium channel blockers, their composition, therapeutic methods, uses, and preparation processes.
Mucosal surfaces at the interface between the environment and the body have developed a number of “innate 10 defences,” that is, protective mechanisms. The initial picture is the defense
The fungal infection mentioned in cleaning those surfaces using liquid. Typically, the amount of liquid layer on the mucosal surface reflects the balance between surfaces with liquid, typically anion (Cl- and/or HCO3-) secretion (and the corresponding anion cation), and absorption of epithelial cell liquid surfaces with liquid. liquid, reversing Na+ absorption,
15 Combined with water and the corresponding anion (Cl- and/or HCO3-). Many diseases caused by mucous surfaces are caused by the presence of too little protective fluid on said mucosal surfaces due to an imbalance between secretion (too little) and absorption (relatively too much). Defective salt transport processes that characterize mucosal dysfunction reside in the epithelial layer of the mucosal surface.
٥٦٧٣

One way to replenish the protective fluid layer on mucosal surfaces is to “re-balance
balance "system by blocking the Na+ channel and liquid absorption. The epithelial protein that stimulates the Na+ restriction step and liquid absorption is represented in the epithelial Na+ channel ("ENaC").
5 ENaC placed the apical surface of the epithelium, i.e. the mucosal surface-environmental interface. Typically, to inhibit ENaC-induced Na+ and fluid absorption, an amiloride-type ENaC inhibitor is delivered to the mucosal surface and maintained in that position for maximum therapeutic benefit.
10 The use of ENaC blockers has been suggested for a range of diseases that occur with increased mucosal hydration. Specifically, ENaC inhibitors are proposed for the treatment of respiratory diseases such as chronic bronchitis (CB chronic bronchitis), cystic fibrosis (CF), and COPD, which reflects the body's inability to eliminate mucus normally. From lungs
15 It eventually leads to chronic infection of the airways. See:
Evidence for airway surface dehydration as the initiating event in CF airway disease, R. C. Boucher, Journal of Internal Medicine, Vol. 261, Issue 1, January 2007, pages 5-16; and Cystic fibrosis: a disease of vulnerability to airway surface dehydration, R. C. Boucher, Trends in Molecular Medicine, Vol. 13, Issue 6, June 2007, pages 231-240 20
Data indicate that the primary problem in both chronic bronchitis and cystic fibrosis is a failure to clear mucus from airway surfaces. Failure to eliminate mucus reflects an imbalance in the amounts of mucus as airway surface liquid (ASL) on the surfaces of the airways.

Concentration of mucus, reduced lubricating activity of pericilial fluid (PCL) activity, adhesion of mucus to the surface of the airways, and failure to remove mucus through ciliary activity to the mouth. Decreased ability to remove mucus leads to the formation of bacterial colonies Chronic bacterial colonization of mucus

Chronic retention of bacteria, the inability of local antimicrobial substances to kill mucus entrapped bacteria on a chronic basis, subsequent to a chronic inflammatory response of the aforementioned type following surface injury, is evident in chronic bronchitis chronic bronchitis and fibrosis
10 Cystic fibrosis.
There is currently a significant unmet medical need for products that treat a range of ailments that are improved by increased mucus hydrolysis, including COPD, chronic bronchitis, cystic fibrosis, and more. Current treatments for chronic bronchitis, COPD and cystic fibrosis focus on treating the following symptoms and/or effects:
15 That mother has land. However, none of the treatments effectively address the underlying problem of clearing mucus from the lungs.
RC Boucher, in US Patent No. 6,264,975, describes the use of the sodium channel blocker pyrazinoylguanidine sodium to hydrolyze mucosal surfaces embolized by the well-known diuretics amiloride, Ben-Izmil, and phenamyl. However, these compounds are latent
20 Relatively speaking, taking into account the restricted mass of the drug that can be inhaled into the lung; (2) which is done
They are rapidly absorbed and thus exhibit a short, undesired half-life at the mucosal surface; and (3) can be freely separated from ENaC. More latent drugs that have longer half-lives on the mucosal surface are needed.
The presence of a small amount of surface protective fluid on other mucosal surfaces is known in physics

From the oral cavity due to parotopathy Sublingual glands Submandibular glands secrete fluid despite continuous Na+ transport (ENaC) induced by absorption of fluid from the oral cavity. Keratoconjunctivitis sicca (dry eye) results from failure of the lacrimal glands Liquid rice at the surface of the liquid absorption process of Na+ continuous 5 harmonic surfaces In rhinosinusitis, there is an imbalance between mucin secretion and related ASL depletion. Lack of secretion of Cl- (and fluid) near the small intestine, combined with increased absorption of Na+ (and fluid) at the end of the ileum results in
in . DIOS (distal intestinal obstruction syndrome).
In elderly patients, increased Na+ absorption (and volume) in the descending 10 colon leads to constipation and diverticulitis.

In recent years, several research programs and biodefense standards have been activated to deal with matters relating to the use of biological agents in terrorism. The aforementioned criteria relate to bioterrorism or the use of microorganisms or biological toxins to kill individuals, spread fear, and disrupt society. For example, the National Institute of Allergy and Infectious Diseases developed

Research on a broad spectrum of bioterrorism and integration of re-emerging infectious diseases. According to the plan, the exposure of a civilian group in the United States of America to Bacillus anthracis spores shows a gap in the overall preparedness of nations against the phenomenon of bioterrorism. Moreover, the report explains that these attacks expose the unmet need for rapid tests, vaccines, and therapeutics.

Further efforts also include many research efforts to study the biology of pathogens that are presumed to be dangerous, such as bioterrorism agents, study the host response to the aforementioned agents, develop vaccines against infectious diseases, evaluate the therapeutic agents currently available and subject to investigation against the aforementioned agents, and develop Diagnostics to identify signs and symptoms of threatening factors. Count those
15 The efforts are benign, but given the large number of potential bioterrorism pathogens available, these efforts have not been able to provide satisfactory responses to all potential bioterrorism risks. In addition, many potentially dangerous pathogens such as bioterrorism agents do not provide sufficient economic incentives for the development of therapeutic or preventive standards in the field. Moreover, even if preventive standards such as vaccines for each pathogen are available, which can...

Until appropriate and effective treatments are available against the risk of bioterrorism, there is still a great need for preventive and curative treatments that can prevent or reduce the incidence of infection resulting from the pathogens causing the disease.
The present invention provides preventive treatment methods. In one aspect, a preventive treatment method is provided including:

In another aspect, post-exposure prophylaxis or a therapeutic method for treating infection with an airborne pathogen includes administering an effective amount of compounds having formula (I) into the lung of an individual in need of said treatment against infections with an airborne pathogen. It includes pathogens that Immunization is carried out through post-exposure prophylaxis, rescue methods and treatment of any pathogen that enters the body through the mouth, nasal tract, and then reaches the lungs. Typically, the pathogens are airborne pathogens15, occurring naturally or by spraying. Pathogens can occur naturally or can be introduced into the media spontaneously after spraying or other methods of introducing pathogens into the media. Many pathogens can be naturally airborne or aerosolized for use in bioterrorism.

Another pathogen that must be prevented is the coronavirus, which causes severe acute respiratory syndrome (SARS).

Currently, most research has focused on ways to mitigate the health effects resulting from internal deposition of radionuclides by accelerating their excretion or removal. These methods focused on soluble chemical forms that have the ability to reach the bloodstream and are deposited at distant systemic sites specific to a specific radioactive element. These methods do not work in cases where the deposited radionuclide 5 is in a relatively insoluble form. Studies have shown that it is most, if not,
All the physicochemical profiles of the precipitated radionuclides obtained as RDDs are in a relatively insoluble form.
A known method to effectively reduce the radiation dose to the lung from inhaled insoluble radioactive aerosols is bronchoalveolar lavage.
<p dir="rtl">10 bronchoalveolar lavage or BAL. The technique, which was adapted from techniques already used to treat patients with alveolar proteinosis, appeared to be a safe, repeatable procedure when performed over an extended period of time. Although there are variations in procedures, the basic method for BAL is to anesthetize the patient, followed by slow infusion of isotonic saline into a single lobe of the lung until residual capacity for function is reached. An additional 15 volumes are then added and dried through gravity cavitation.</p>
Results from animal BAL studies indicate that approximately 40% of deep lung content is removed by the acceptable succession of BALs. In some studies, there is significant variation between animals in terms of the amount of radionuclide. The reasons for the change are not currently clear.
Moreover, on the basis of an animal study, it appears that reducing the high dose of BAL treatment leads to attenuation of the health effects resulting from the inhalation of radionuclides.
Insoluble radionuclides. In the study, adult dogs inhaled insoluble 144Ce-FAP particles. Two groups of dogs are given 144Ce lung contents that cause radiation-induced pneumonia and lung fibrosis (about 2 minimum batch amount/kg body mass), with one group treated with 10-sided lavage between 2 and 56 days post-exposure The group was exposed to the infection and the untreated group

The third infection level is below 144Ce compared to the level seen in the group treated with post-treatment BAL (about 1 minimum batch/kg), but these organisms are untreated. These animals are allowed to survive for the duration of their lives, which extends to 16 years. As the initial lung content of 144Ce among the dogs in each group, the dose rates overlap the cumulative doses in each group. However, the effect of BAL in reducing the risk of pneumonia/fibrosis is evident from the survival curves. In the untreated CAPS group with lung contents of 1.5-2.5 minimum batch volume/kg, median survival was 370 ± 65 days. For the dogs that were done
treated, the mean survival is 1270±240 days, which is statistically significantly different. The third group, which receives lung contents of 144Ce of 0.6-1.4, has the lowest boost amount.

The mean survival time was 1800±230, which was statistically significantly different from the treated group. Importantly, compared to the increased survival time, dogs in the group not treated with high doses die from serious lung effects (pneumonitis/fibrosis) while untreated dogs survive. Alternatively, dogs that have been treated, such as dogs in The group not treated with low doses developed lung cancer (hemangiosarcoma or carcinoma). Thus, the dose reduction resulting from treatment with BAL appears to produce biological effects in the lung that would be expected on the basis of radiation doses received by the lungs.
received
On the basis of these results, it is clear that further reducing residual radiation dose using any method or combination of methods to enhance particle clearance from the lung can potentially reduce lung health effects. However, BAL is a procedure that has several drawbacks. BAL is a highly invasive procedure that should be performed in specialized medical centers by trained pulmonologists. Therefore, BAL is expensive. Based on the disadvantages of BAL, it is not the treatment of choice that is readily available and accessible to thousands of individuals who require accelerated removal of radioactive particles, for example, in the event of a nuclear attack. In the event of a nuclear attack or

In nuclear accidents, there is a need for direct and easy treatment of thousands of individuals at risk of injury. Sodium channel blockers administered via inhaled aerosol restore rehydration of airway surfaces. Hydration of these surfaces of the airways helps in eliminating the accumulation of mucus secretions and related particulate matter.

As previously explained, significant lung hazards following a radiation attack, such as contaminant explosion, result from inhalation and retention of insoluble radioactive particles. As a result of detention
<p dir="rtl">10 With radioactive particles, cumulative lung injury is greatly increased, eventually leading to lung fibrosis/pneumonitis and possible death. Insoluble particles are not completely eliminated by chelating agents due to the absence of those particles in solution. To date, physical removal of particulate matter via the BAL method is a treatment method that appears to be effective for remission of radiation-induced lung disease. As explained previously, BAL is not an actual mitigation treatment</p>
<p dir="rtl">15 Radioactive particles inhaled into the body. Therefore, it is preferable to provide a treatment that helps eliminate radioactive particles from the airways. Unlike BAL, the treatment is simple to apply and is graduated according to a large-scale radiation injury scenario. In addition, it is also required that the treatment method be available to a number of individuals in short periods of time.</p>

Various types of dry powder inhalers, high-pressure metered dose inhalers, wet inhalers, nebulizers, or puffs. The appropriate method of administration can depend on several factors including the patient and the condition or disorder being treated.
<p dir="rtl">5 The formula can be presented in the form of a unit dosage or in mass form, for example in the case of formulas intended to be measured by inhalation means, and it can be prepared by any of the methods well known in the field of pharmacy. Generally, the method includes the step of combining the active ingredient with a carrier, diluent or excipient and optionally one or more additional ingredients. Generally, the formula is prepared by systematically or vigorously combining the active ingredient with one or</p>
<p dir="rtl">10 More liquid carriers, excipient diluents or excipients or finely divided solid carriers, diluents or excipients, or both, and then, if necessary, form the product into the desired formulation.</p>
In one preferred embodiment, the composition is an inhalable pharmaceutical composition that is suitable for inhalation and delivery into an endotracheal space. Typically, this is
<p dir="rtl">15 The composition is an aerosol containing particles for delivery using a nebulizer, metered dose inhaler (MDI), nebulizer, or dry powder inhaler (DPI). The aerosol formulation used in the methods of the present invention can be a liquid (e.g., solution) suitable for administration via a nebulizer, nebulizer inhaler, or MDI, or a suitable dry powder</p>
20 To give via MDI or DPI.
Aerosols used for respiratory drug administration are typically polydisperse; As it consists of particles of different sizes. Typically the particle size distribution is described by the Mass Median Aerodynamic Diameter (MMAD).
Geometric Standard (GSD) and Aerodynamic Diameter
25 Deviation. For optimal intrabronchial drug delivery, the MMAD has a range of approx
٥٦٧٣
-٤٨-
1 to about 10 µM and preferably from about 1 to about 5 µM, and a GSD of less than 3, preferably less than about 2. Aerosols with a MMAD greater than 10 µM are usually too large when inhaled to reach the lung. Aerosols with a GSD greater than about 3 are not preferred for delivery as they deliver a large proportion of the drug to the oral cavity. To achieve the desired particle sizes in a powder formulation, the particle size on the active ingredient can be reduced using conventional techniques such as crushing or spray drying. Non-restrictive examples of other processes or techniques that can be used to obtain respirable particles include spray drying, sedimentation, supercritical fluid, and freeze-drying. The required portion can be separated by grading or air sieving. In one
10 Models, the particles are in crystalline form. For crystalline formulations, particle size is determined by selection of a specific model of nebulization unit, nebulization inhaler, or MDI.
Aerosol particle size distributions are determined using equipment well known in the art. For example, a multi-stage cascade device or other appropriate methods such as those specified in the chapters of the American Pharmacology Encyclopedia appear as distinct devices from the metered dose and dry powder inhaler 15.
Dry powder formulations may be formed for topical delivery to the lung by inhalation without the use of excipients or carriers, alternatively including the active ingredients in a dry powder form that have a particle suitable for inhalation. Dry powder formulations may also include a combination of the active ingredient and a suitable powder base (carrier 20 / diluent / excipient) such as mono-, di- or poly-saccharides (e.g.
lactose or starch). Typically lactose is a preferred excipient for dry powder formulations. When a solid excipient such as lactose is used, the particle size of the excipient is generally larger than the active ingredient to aid in dispersion of the formulation in the inhaler.
Examples of non-captive dry powder inhalers include a 25-dose multi-dose inhaler, multiple pre-measured dose devices, and capsule-based inhalers.

and single-dose inhalers. An inhaler reservoir contains a large number of doses (such as 60) in a single container. Before inhalation, the patient turns on the inhaler, causing the inhaler to measure a single dose of medication obtained from the reservoir and prepare it for inhalation. Examples of inhaler reservoirs include DPIs for example
5 Exclusively Turbohaler® by AstraZeneca and ClickHaler® by Vectura.
In a pre-measured multi-dose nebulizer, each single dose is prepared in a separate container, and turning on the nebulizer before inhalation releases a new dose of drug from its container and prepares it for inhalation. Examples of multidose DPI sensors include but are not limited to SKUS® acquired from GSK,
10 Gyrohaler® obtained from Vectura, and Prohaler® obtained from Valois. During inhalation, the patient's respiratory flow accelerates the exit of the powder from the device and into the oral cavity. For a capsule inhaler, the formula is contained in a capsule and stored outside the inhaler. The patient pops the capsule into the inhaler, turns on the inhaler (and pierces the capsule), and then inhales. Examples include the RotohalerTM
(IB) HandiHalerTM, (Novartis) SpinhalerTM, (GlaxoSmithKline) 15
TurboSpinTM (PH&T). With single-use inhalers, the patient turns on the inhaler to prepare it for inhalation, inhales, then disposes of the inhaler and packaging. Examples include TwincerTM (U Groningen), OneDoseTM (U GroningenTM).
(Manta Devices) and Manta InhalerTM (GFE).
20 In general, a dry powder inhaler uses the turbulent flow properties of the powder path
To disperse the excipient-drug accumulation products and deposit the active ingredient particles in the lung. However, a specific dry powder inhaler uses a vortex dispersion chamber to produce particles of the desired shape. In a vortex dispersion chamber, the drug enters the circular dispersion chamber tangentially so that the flow path and the drug move along the outer chamber wall. As the drug formula moves along the wall
25 The aforementioned round bounces off and the agglomeration product is broken away by the impact forces. The air path turns towards
٥٦٧٣
-٥٠-
The center of the orthogonally projecting chamber. Particles that have sufficiently small dynamic sizes can follow the flow path and exit the chamber. When applied, the dispersion chamber acts like a small jet mill. Based on the properties of the formulations, macroformulated lactose particles can be added to assist in dispersion through impaction with API particles.
5 The TwincerTM single-dose inhaler appears to operate using a circular vortex dispersion chamber referred to as an “air classifier” See US Patent Publication No. 2006/0237010 of Rijksuniversiteit Groningen. Research published by the University of Groningen has shown that a 60 mg dose of pure powdered colistin sulfomethate can be effectively delivered as an inhalable dry powder (Technique 10).
In preferred embodiments, the aerosol formulation is delivered in dry powder form using a dry powder inhalation device where particles are emitted from the inhalation device comprising an MMAD in a range from about 1 µm to about 5 µm and a GSD of less than about 2.

These formulations may be administered using commercially available nebulization devices or another nebulization device capable of breaking the formulation into particles or droplets suitable for deposition into the respiratory tract. Non-restrictive examples of nebulization means that may be used for aerosol delivery of the composition of the invention include airjet nebulization means, air or breath-assisted nebulization means, or nebulization means

Commercially available nebulizers are Aeroneb® Go nebulizer (Aerogen) and eFlow nebulizer (Pari (Pharma).
A jet atomizer uses a high-velocity stream of air blown through a water column to produce droplets. Particles unsuitable for inhalation affect walls or aerodynamic barriers.
<p dir="rtl">10 The air-assisted nebulizer, or breather, operates essentially the same as a jet nebulizer except that inhaled air passes through the primary droplet generation area to increase the nebulizer's output rate as the patient inhales.</p>
In the ultrasonic sputtering process, piezoelectric crystal vibration causes surface variations in the drug reservoir such that droplets are formed. In atomization media with porous dishes,
<p dir="rtl">15 The generation of pressure fields by a liquid forces sound energy through the pores of the lattice where it breaks into droplets by the Rayleigh refraction process. The sound energy may be supplied by a vibrating horn or plate guided by a piezoelectric crystal, or by the vibrating grid itself. Examples of non-restricting sprayers include any single or double liquid sprayer or nozzle that produces droplets of the appropriate size. The single fluid spray works by forcing liquid through one or more nozzles.</p>
<p dir="rtl">20 The process of jetting the liquid causes it to disperse into droplets. Dual-fluidic atomizers operate by either gas or liquid forces through one or more nozzles, or by the impingement of the liquid jet by another liquid or gas jet.</p>

Mucus modifying agents or mucins useful in the combinations and methods described herein include reducing agents, surfactants, detergents, expectorants, and 5-deoxyribonuclease agents.
10
Mucin proteins are organized according to high molecular weight polymerases through the formation of covalent (disulfide) and non-covalent bonds. The distribution of covalent bonds with reducing agents is a well-known method of reducing the viscoelastic properties of mucus in the organism and would be expected to act on Reducing mucus adhesion and improving organism clearance Reducing agents are well known in reducing mucus viscosity in the laboratory and are commonly used as adjuncts to processed sputum samples. Examples of reducing agents include sulfide-containing molecules or phosphines capable of cleaving protein di-sulfide bonds including, but not limited to:
N-acetyl cysteine, N-acystelyn, carbocysteine, glutathione, dithiothreitol, thioredoxin containing proteins, and tris (2-carboxyethyl) phosphine.
15 N-acetyl cysteine (NAC) has been approved for use in combination with chest physiotherapy to loosen viscous or thickened airway mucus. Clinical studies evaluating the effects of oral or inhaled NAC in CF and COPD have shown improvement in the rheological properties of mucus and trends in improved function. Lung and pulmonary exacerbations9 However, the preponderance of clinical data suggests that NAC is best used as a marginal therapeutic agent for the treatment of NSAIDs.
20 Airway mucus when covering through the mouth or by inhalation. The recent Cochrane review of current clinical areas on the use of NAC has not provided evidence of the effectiveness of NAC for CF. The marginal clinical benefit of NAC is reflected in:
NAC is a relatively inactive reducing agent that is only partially active on the surface of the airways. Very high concentrations of NAC are 200 mM (or 3.26%).
٥٦٧٣
-٧٨-
It is absolutely required to reduce MuC5B, the major airway mucin reducing gel, in vitro. Moreover, at the average pH of the airway surface (measured in the pH range of 6.0 to 7.2 in CF and COPD airways), NAC exists only partially in the reactive state as a negatively charged thiolate compound. Thus, in vitro, it is given However, current aerosol devices would be expected to be unable to detect NAC 5 at very high concentrations
The therapeutic efficacy of 20% Mucomyst solution was achieved on distal airway surfaces in the relatively short time scales (7.5-15 minutes) typically used.
In nonclinical studies, NAC labeled 14C, administered by inhalation,10 shows rapid elimination from the lung with a half-life ranging from 6 to 36 minutes.
NAC is given in high concentration, hypertonic inhalation solution (20% or 1.22 M) causes bronchoconstriction and cough. In several cases, it is suggested to give NAC with a bronchodilator or to improve the tolerance of the said agent.
Therefore, reducing agents such as NAC are not well suited for bolus or spray administration. 15 However, delivery of reducing agents by pulmonary aerosol infusion is expected to increase efficacy, and allow the concentration of the reducing agent in the inhalation solution to be reduced (expected to increase tolerability).
Surfactants and detergents are diffusion agents that reduce mucus viscosity and improve mucus clearance. Examples include surfactants
palmitoyl-, palmitic acid, PF, dipalmitoylphosphatidylcholine
20 oleoylphosphatidylglycerol, surfactant-binding proteins (such as B, SP-A, or C), or can be derived from animals (such as obtained from lung lavage of cow or calf or minced pig lung) extracted from minced pig lung or combinations thereof.

In vitro measurement of sodium channel blocking activity and reversibility
One experiment used to evaluate the mechanism of action and/or potency of the compounds of the present invention includes determining a cavitary drug inhibition of airway epithelial sodium currents measured at a short circuit current (15 ISC) using airway epithelial monolayer cells mounted in Ussing chambers. . Cells obtained from recent resections of the airways of humans, dogs, sheep or rodents were seeded onto a 0.4-micron CoStar SnapwellTM Inserts device and cultured at air-liquid interface (ALI) conditions in a hormone-specific medium And tested to determine sodium transport activity (ISC) 20 during washing in KBR (Krebs Bicarbonate Ringer) in chambers using. All additions of the test drug to the cavity bath are made using dose addition protocols of the same amount (from 1 x 11-10 M to 3 x 10-5 M), and the cumulative change in the ISC (inhibition) is recorded. All drugs were prepared in dimethyl sulfoxide In the form of crude solutions at a concentration of 1 x 10-2 M and stored at -20 °C, eight preparations were typically provided

After determining the maximum concentration (5 × 10-5 M), the 3-Mart ground bath was exchanged with fresh drug-free KBR solution, and the resulting ISC was measured after each wash for approximately 5 minutes. Reversibility was determined as the percentage of return to the baseline value of the current Sodium after the third wash 5 All data from voltage clamps were collected via a computer interface and analyzed separately.
Dose-effect relationships for all compounds were considered and analyzed using Prism 3.0 software. The values of IC50, maximum effective rate, and reversibility were collected and compared to amiloride and Ben Izmail as positive comparison samples. The potency of the sodium channel blocking activity of the representative compounds relative to amiloride in a freshly excised cell from a calvarial airway is presented in Table 1.

The total radioactive counters are measured every 5 minutes for an hour of observation period. The rate of radiolabeled lung clearance represents the MCC rate in the organism. The advantage of the mentioned system is the precise stimulation of the human lung medium. The model also allows for the collection of concurrent PK/PD information from the plasma and urine sample throughout the testing period. There are also many techniques to measure the property value
5 on the surface of the airways during MCC measurements. This includes collection of sputum condensation products or the paper filter method to obtain ASL through bronchoscopy.
The previously mentioned bovine model was used to evaluate the in vivo effects (potency/persistence) of the aerosol-delivered test agent on MCC. Treatments consisting of either 4 ml of the test agent, or the test agents in combination with HS, were tested to determine Merge HS with

The test solutions were administered by spraying using the Raindrop atomizer at a flow rate of 8 L/min and connected to a dosimeter system consisting of a solenoid valve and a compressed air source (20 psi). The deposited dose of the drug dose in the lung of the sheep after aerosol administration was estimated using the Raindrop atomizer.
