Description

This application claims the benefit of priority in provisional application serial No. 60/410,661 filed on Sep. 13, 2002.[0001]

FIELD OF THE INVENTION

The present invention generally relates to the treatment and/or prevention of upper respiratory pathology and/or disease in humans (and other susceptible animals). In particular, the present invention relates to novel compositions, for the acute treatment and also the long term treatment and/or prevention of mixed rhinitis in man and in animals which does not predispose the patient to development of rhinitis medicamentosa.

BACKGROUND OF THE INVENTION

Rhinitis is a term used to describe the symptom complex related to irritation and inflammation of the nasal passageways (see, e.g., Middleton's Allergy Principles & Practice Volume II Fifth Edition Copyright 1998). Rhinitis affects 50 to 60 million Americans and the prevalence of allergic rhinitis has increased dramatically over the past 30 years.

Patients with rhinitis may experience a variety of symptoms including sneezing, rhinorrhea, nasal itching, congestion, and/or postnasal drainage. As a result, patients with these symptoms often experience headaches, fatigue, impaired concentration, reduced productivity, loss of sleep, increased occupational risk, increase in asthma, sinusitis, and otitis, and decreased emotional well being and social functioning (see, e.g., “ Advice From Your Allergist” published by American College of Allergy, Asthma & Immunology, revised July 2000). Occasionally, children with chronic rhinitis develop altered facial growth and orthodontic problems. (See Table 1)

Chronic rhinitis, (rhinitis of greater than 6 weeks duration), is among the most common problem presenting to primary care physicians. Rhinitis can be caused by an allergy to inhalants, i.e., pollen, mold, animal dander and allergy to foods (58 million Americans). Non-allergic causes including strong odors, sudden temperature changes, alcohol ingestion, airborne irritants, skiing/jogging, pregnancy, spicy foods, and certain medications (e.g., topical agents such as certain alpha-adrenergic vasoconstrictors, ***e, eye drops and oral agents such as antihypertensives, birth control pills, and certain phenothiazines) affect approximately 19 million Americans. Forty-four percent of the patients with allergic rhinitis have concomitant non-allergic rhinitis. This later group of patients with mixed rhinitis represents an estimated 26 million people in the United States. Prior to the present invention, however, there has not been an effective single entity medication for treatment and/or prevention of mixed rhinitis in patients.

The attached flowchart (See, FIG. 1) is useful in establishing a pattern for pharmacalogic therapy for mixed rhinitis, which embraces an integrated approach (Figure Source: “Middleton's Allergy Principles & Practice”, Vol. II, 5 ^thEdition, Copyright 1998). Currently, there are many single entry topical medications for treatment of allergic rhinitis. Nasal steroids, which top the list, (See, Table 5 below) help both the immediate and late phase response by modulating the production and effects of the ever-growing family of cytokines. Recently, cytokines have been shown to play a role in non-allergic rhinitis pathophysiology as well.

The diagnosis of mixed rhinitis is made when patients are known to have allergic rhinitis but their symptoms are clearly worsened by non-allergic triggers. Mixed rhinitis is one of the more difficult entities to treat, probably because of the great variety of provocative stimuli and its unremittingly perennial nature. Patients with mixed rhinitis may also already have an iatrogenic addiction to topical decongestants (rhinitis medicamentosa), chronic sinusitis, and/or nasal polyps as a result of their long-standing illness.

Empiric treatment with a topical broad based agent that is indicated for allergic rhinitis and non allergic rhinitis is a reasonable choice for first line therapy, but most patients need immediate relief of their symptoms to reinforce their long term plan with short term relief (see, e.g., Clinician's Manual on Rhinitis: Both Allergic and Nonallergic, published by Science Press, Copyright 2001). Topical decongestants fit this need, but used alone, they can induce rhinitis medicamentosa (iatrogenic rhinitis). Botanical agents which cool the nasal membranes such as menthol, camphor and eucalyptus give an immediate sensation of improved airflow. Interestingly, this sensation occurs without any actual change in nasal airway diameter or restriction. Thus, there is a subjective feeling of improvement with immediate results from the patient's perspective gives the patient the “security” of being able to breathe more easily (see, e.g., “Asthma and Rhinitis” edited by William W. Busse, & Stephen T. Holgate, published by Blackwell Science, Copyright 1995).

When it is not possible to definitively diagnose the type of rhinitis present (i.e, allergic vs. non-allergic), emphasis on broad based treatment should be considered. At present all of these broad based treatment components are available only as single entity formulations, i.e., single entity topical steroids, single entity topical decongestants (some with cooling aromatic components), single entity topical antihistamines or topical anticholinergic agents. Thus, there is a need in the art for a fixed integrated pharmacotherapy composition which can effectively treat the allergic as well as the non-allergic components of mixed rhinitis without harmful sequella, e.g., rhinitis medicamentosa. Prior to the present invention there had been no formulation useful for treatment of acute mixed rhinitis which combined effective amounts of a suitable nasal decongestant and a suitable corticosteroid that can also be used on a long term basis without inducing long term use complications such as rhinitis medicamentosa. The cost and compliance benefits of a such a composition are also of undeniable importance.

Presently, when long-term decongestant use is indicated, physicans must rely on systemic decongestants to avoid the adverse effects of long term topical use. Systemic therapy with decongestants can also produce adverse effects including; nervousness, insomnia, irritability headache, palpitations, tachycardia, hypertension, glaucoma, and decreased urinary flow as well as sexual dysfunction in males which greatly limits the use of oral decongestants. One of the only three alpha-adrenergic agonists available, phenylpropanolomine, was recently removed from the market because of fatal cardiovascular events related to its use, further limiting this choice of therapy. With only two systemic decongestants left, the therapy dilemma is even more complicated. Accordingly, there is a need in the art for a topical composition (as provided by the present invention) which can immediately alleviate congestion and can also be used on a long term basis without the risk of developing rhinitis medicamentosa or the risk adverse effects encountered with systemic decongestant therapy. The novel compositions provided by the present invention combine the use of topical nasal decongestant with an anti-inflammatory agent (topical steroid) and substantially eliminates the risk of rhinitis medicamentosa and concomitantly eliminates the risk of systemic decongestant use.

Likewise, in animals, especially companion animals such as dogs, cats and horses, there exists a need in the art for a composition adapted for topical administration and or nebulization which can effectively treat upper respiratory conditions in patients suffering from allergies, and/or infectious/inflammatory disorders such as inflammatory airway disease (IAD) and/or mixed rhinitis and that also may be used for treatment of lower respiratory conditions, e.g., recurrent airway obstruction (heaves). In horses, especially competition animals such as racing thoroughbreds, for example, inflammatory airway disease and/or upper respiratory inflamation can be troublesome and economically devastating. Pharyngitis, sinusitis and guttural pouch inflammation and/or infection if not properly treated can become a chronic manifestation in training animals and decrease performance. Inflammatory airway disease and pharyngitis or mixed rhinitis is often observed in young athletic horses, e.g., in two year olds in training. Mechanical irritation from breathing cold air in conjunction with environmental contaminants (dust, mold spores and the like) with or without an infectious component can predispose the animal to a lingering bout with upper airway inflammation such as pharyngitis or inflammatory airway disease. Clinical signs may be subtle and are often manifested as a chronic cough, excess mucus in the trachea and poor performance. Otherwise, the animal may have a normal attitude and appetite.

Treatment approaches to upper airway disease in the horse have largely been directed at treatment of the inflammation and broncho constriction which manifest especially with IAD. Aerosolized therapy with anti-inflammatory agents such as corticosteroids has been tried via nebulization or metered dose inhalation (MDI). In addition, bronchodilators such as albuterol have been used with some measure of success and also immunostimulants and antibiotic have been advocated. Treatment of pharangitis and gutteral pouch inflammation has been directed to various throat washes and lavages such as e.g., sodium iodide with or without DMSO. These may be used in conjunction with systemic antibiotic and or corticosteroid or other systemic anti-inflammatory agents such as NSAIDs, e.g., phenylbutazone or flunixin megulamine. However, prior to the present invention there has not been a single entity medication adapted for direct topical application which utilizes a unique combination of active agents for the effective treatment of upper airway disease in animals.

SUMMARY OF THE INVENTION

The present invention provides compositions and methods useful for the non-addictive treatment and/or prevention of allergic, non-allergic and mixed rhinitis. In one embodiment, the compositions of the invention are comprised of effective amounts of a suitable nasal decongestant; a suitable synthetic or non-synthetic corticosteroid; and a suitable anticholinergic agent.

The compositions and methods provided by the invention may be used for relief of acute symptoms of allergic as well as non-allergic rhinitis, but are especially useful for long term use in patients with mixed rhinitis. The compositions and methods of the invention can be used for treatment and/or prevention of mixed rhinitis on a long term basis and substantially reduce or eliminate the risk of the patient developing rhinitis medicamentosa (e.g., as currently is frequently seen with long term use of the presently available topical nasal decongestant formulations). The compositions and methods of treatment provided by the invention also eliminate the risk of adverse sequella seen from therapeutic regimens which employ the systemic use of decongestants.

In one embodiment of the invention, the compositions provided can further comprise a suitable aromatic, e.g., a Botanical agent such as camphor, menthol or eucalyptus. Yet another embodiment of the invention, provides the compositions for treatment and/or prevention of allergic, non-allergic and/or mixed rhinitis which may further comprise an effective amount of a suitable antihistamine.

Another embodiment of the invention provides compositions comprised of effective amounts of a suitable nasal decongestant; a suitable corticosteroid; a suitable anticholinergic agent and a suitable antihistamine with or without the addition of a suitable aromatic agent. The core compositions of the invention comprised of a suitable nasal decongestant; a suitable corticosteroid and a suitable anticholinergic agent may further comprise optional suitable antimicrobials (antibiotics and/or antifungal and/or antiviral agents); cytokine modulators and/or inhibitors; leukotriene antagonists cromolyn sodium and/or a suitable NSAID agent.

The compositions of the invention are also useful for the long term treatment of sequella (e.g., constricted upper airway) in patients suffering from sleep apnea and receiving treatment with a constant positive pressure airway (CPAP) machine.

DETAILED DESCRIPTION OF THE INVENTION

The present invention provides compositions and methods for the treatment and/or prevention of upper respiratory pathology and/or disease in man and in animals. The compositions provided herein can be used to treat and/or prevent any of a variety of upper respiratory conditions in man and animals including, but not limited to, allergic, non-allergic and mixed conditions having both allergic and non-allergic components (See, e.g., Table 4).

In one embodiment, the compositions of the invention are adapted for topical, e.g., intranasal use and may be used in patients on a long term basis (for therapy of chronic or recurring upper respiratory conditions requiring daily or as needed, PRN, treatment) with a substantially reduced risk of adverse side effects such as rhinitis medicamentosa. Thus, the present invention also particularly provides methods of use for the novel compositions, for acute as well as long term treatment and/or prevention of upper respiratory conditions (e.g., mixed rhinitis in man and pharyngitis in animals) which does not predispose the patient to development of iatrogenic rhinitis (rhinitis medicamentosa).

In one embodiment, the present invention provides a composition that is useful for the non-addictive treatment and/or prevention of allergic, non-allergic and/or mixed rhinitis comprised of effective amounts of a suitable nasal decongestant; a suitable synthetic or non-synthetic corticosteroid; and a suitable anticholinergic agent. Examples of suitable nasal decongestants include, but are not limited to, any of a number of nasal decongestants that are currently used in prescription and over the counter preparations. Specific examples of suitable nasal decongestants include, but are not limited to, oxymetazoline, phenylephrine hydrochloride, phenylpropolamine hydrochloride, pseudophedrine and the like. Other examples of suitable decongestants (as well as other required agents, i.e., suitable corticosteroids and anticholinergic agents) that are adaptable for topical intranasal use can be found e.g., in Middleton, Elliott, Jr. et al., “Allergy Principles and Practice”, 5 ^thEd., Volumes I & II, Mosby-Year Book, Inc. (1988)) (ISBN 0-8151-0072-8) the contents of which are incorporated herein by reference in its entirety. (See also, The Physicians Desk Reference 56^thEd., Medical Economics, Inc.

In general, it is preferable that the compositions of the invention be adapted for localized, e.g., intranasal delivery, with the active agents in a solution suitable for spraying or misting or other direct topical application. However, as can be appreciated, other variations such as powders and the like are possible and are within the scope of the invention. A presently preferred method of localized delivery of the compositions is via intranasal administration of a fine mist utilizing a standard metered dose pump, which can be calibrated to deliver an exact amount of the solution per administration, e.g., 0.1 ml per pump. It can also be appreciated that other forms of application are possible and are within the scope of the invention.

Given the many possible combinations of the required classes of active agents that are possible, it can be appreciated by one of skill in the art that the effective amount for any particular component of the compositions of the invention can vary depending upon the agent and/or the combination of agents selected, the condition being treated and the therapeutic regimen that is desired. However, given the teachings set forth herein one of skill in the art can optimize the effective amount of a given active agent given the identity of the other required agents of the combination for the compositions of the invention, the subject and condition being treated and the desired therapeutic regimen.

Thus, in one embodiment, a core combination of effective amounts of a suitable nasal decongestant; a suitable synthetic or non-synthetic corticosteroid; and a suitable anticholinergic agent are provided for the treatment of upper respiratory conditions in man and in animals. It is contemplated that other active agents may be added to the core compositions as desired. In particular, in another embodiment of the invention, the compositions for treatment and/or prevention of allergic, non-allergic and/or mixed rhinitis set forth above may further comprise an effective amount of a suitable aromatic agent such as e.g., camphor, eucalyptus, menthol or the like.

In another embodiment of the invention, the compositions for treatment and/or prevention of allergic, non-allergic and/or mixed rhinitis set forth above may further comprise an effective amount of a suitable antihistamine. Examples of suitable antihistamines include, but are not limited to, cetirizine, chlorpheniramine, diphenhydramine, dexchloropheniramine, astemizole, azelastine, acrivastine, loratadine, terfenadine, cyproheptidine and the like.

Also contemplated by the present invention are the optional addition of suitable antibiotics and/or suitable antifungal agents and/or antiviral agents to the core compositions, as desired. The antibiotic and or antifungal agents can be selected from any of the currently available antimicrobial agents useful for treatment of upper respiratory infections. Examples of suitable antibiotics include any of the antibiotics commonly used to treat upper respiratory infections, e.g., penicillins, cephalosporins, sulfonamides, neosporin, polysporin, mupirocin and the like. In humans, it may be less desirable to utilize penicillin derivatives due to allergic problems associated with their use. Examples of suitable antifungal agents include, but are not limited to miconazole, ketaconazole and the like. One of skill in the art may also appreciate that other natural antimicrobial agents may be utilized including but not limited to, e.g., pentisols such as xylitol. Antimicrobial, e.g., antibiotic selection and dosage may, of course, vary depending upon physician or veterinarian preference and the infectious agent to be treated and the desired therapeutic regimen.

Other agents which may be added to the core compositions of the invention include, cytokine modulators or inhibitors and/or antileukotrienes or leukotriene receptor antagonists. Examples of cytokine modulators can include pimecrolimus, tacrolimus, zileuton and the like. Examples of suitable leukotriene receptor antagonists include, but are not limited to montelukast sodium, and zafirulakast.

Cromolyn sodium (also known as sodium cromoglycrate (SCG)) and/or pryanoquinolones such as, e.g., nedocromil sodium, and other mast cell stabilizers may also be added to the core compositions set forth herein. Likewise, in certain instances, non-steroidal anti-inflammatory agents such as, e.g., acetominophen, ibuprofen, ketofen and/or Cox-2 inhibitors such as, e.g., rofecoxib or celecoxib may be added to the core compositions of the invention. To further reduce inflammation and in certain embodiments these NDAID agents may be used in place of corticosteroid agents in the core formulations. Anti-serotonin agents may also be utilized as an adjunct to the core formulations.

In another embodiment, the invention provides a method for the non-addictive treatment and/or prevention of allergic, non-allergic and/or mixed rhinitis comprised of administering a therapeutic and/or a preventative amount of a composition comprised of a suitable nasal decongestant; a suitable synthetic or non-synthetic corticosteroid; and a suitable anticholinergic agent. In a presently preferred embodiment, the method comprises the intranasal administration of the compositions set forth herein. Depending upon the severity of the rhinitic condition, the compositions may be administered 1×/day or 2×/day or as needed for symptomatic relief.

In a presently preferred therapeutic regimen for treatment of rhinitis, e.g., mixed rhinitis, the compositions of the invention can be administered, e.g. as an intranasal spray, in a split dosage fashion wherein a first treatment can be administered to relieve the acute nasal congestion and decrease swelling of nasal passages. The first administration is followed up by a second administration of the nasal spray at a preselected time after the first administration to provide a more long term and effective relief of the mixed rhinitis being treated. For example, a first administration of the composition is administered to the subject and a second administration is followed at between about 5 and about 45 minutes but preferably at about 10-15 minutes following the first administration. This split dosage regimen can be repeated daily or 2×/day or as needed to control or provide symptomatic relief of the rhinitic condition being treated.

3. Add only one of the items listed below: [0043]
1. 6 cc of 0.25 gm/cc Triamcinolone Acetate with buffers, stabilizers & surfactants (the volume, and thus the concentration of Triamcinolone Acetate in the final composition can range from about 3 cc to about 24 cc of a 0.25 gm/cc solution); or [0044]
2. 6 cc of Betamethasone Dipropionate @ 84 meq/0.1 cc with buffers, stabilizers & surfactants (the volume, and thus the concentration of Betamethasone Dipropionate in the final composition can range from about 3 cc to about 24 cc of a 84 meq/0.1 cc solution); or [0045]
3. 5 cc Budesonide 384 meq/cc with buffers, stabilizers & surfactants (the volume, and thus the concentration of Budesonide in the final composition can range from about 3 cc to about 24 cc of a 384 meq/cc solution); or [0046]
4. 11 cc Flunisolide in 0.025% solution with buffers, stabilizers & surfactants (the volume, and thus the concentration of Flunisolide in the final composition can range from about 3 cc to about 24 cc of a 0.025% solution); or [0047]

6. 10 grams of 0.05% Mometasone Furoate Monohydrate to allow 100 meq per 0.10 cc (the volume, and thus the concentration of Mometasone Furoate Monohydrate in the final composition can range from about 5 cc to about 40 cc of a of 0.05% Mometasone Furoate Monohydrate solution at 100 meq per 0.10 cc). [0049]
Optional: [0050]
4. 5 cc Azelastine HCl in a 0.1% solution (0.137 mg) an antihistamine helpful for extra allergy and vasomotor rhinitis control may be added (the volume, and thus the concentration of Azelastine HCl in the final composition can range from about 1.25 cc to about 7.5 cc of a of 0.1% Azelastine HCl solution) [0051]
The above composition, for example, can be useful for the methods of treatment and or prevention of upper respiratory conditions in man and in animals provided herein. However, it can be appreciated by one of skill in the art that other of the embodiments provided by the invention are, likewise, useful in the methods set forth herein. For example, in one embodiment the invention provides a composition useful in a method for the non-addictive treatment and/or prevention of an upper airway condition in a subject, comprising administering to the subject a composition comprising effective amounts of a suitable nasal decongestant; a suitable corticosteroid; and a suitable anticholinergic agent. The subject can be a human or animal subject and the upper airway condition can be, e.g., rhinitis (allergic, non-allergic and mixed) in man or pharyngitis in horses. The compositions set forth herein are also useful in methods of treatment of other upper respiratory and respiratory conditions, e.g., for treatment of inflammatory airway disease, heaves, guttural pouch inflammation and/or infection and sinusitis in horses. [0052]
In one embodiment, the compositions of the invention are adapted for intranasal administration such as via spraying, misting, or other direct topical application to the membranes or the compositions can be adapted for inhalation via a metered dose inhalation device or nebulization of the composition. The condition being treated, will likely dictate the choice of administration. For example, in humans suffering from mixed rhinitis, the compositions may be administered by a metered dose inhaler or spray or mist intranasal applicator. Whereas, in a horse, for example, the route of administration for pharyngitis may be via direct topical administration of the composition to the oropharynx via the use of a catheter (e.g., a canine urinary catheter or the like) or nasal cannula that is passed up the nasal passages such that the tip of the catheter or cannula is adjacent the target pharyngeal tissue and the composition is sprayed on topically.
