Description

THE COMBINATION OF TOPICAL NASAL MAST CELL STABILIZERS AND TOPICAL NASAL STEROIDS
The present invention relates to prevention and treatment of the symptoms of seasonal and perennial allergic rhinitis. More particularly, the present invention relates to the prevention and treatment of the symptoms of seasonal and perennial allergic rhinitis by the application of a combination of topical nasal mast cell stabilizers and topical nasal steroids.
BACKGROUND OF THE INVENTION
Seasonal allergic rhinitis is most frequently caused by pollen, pollen fragments and mold spores. The airborne pollens, pollen fragments and mold spores are deposited on the nasal mucosa. In sensitive individuals, rhinitis symptoms develop which include puffy, sore eyes, sneezing, nasal congestion, sinus headaches and fatigue.
The chronic symptoms of perennial allergic rhinitis are most frequently caused by reaction to perennial allergens, such as, house dust mite, mold, cockroach, animal saliva, urine, and dander. The symptoms resemble those of seasonal allergic rhinitis but the duration is year round or episodic depending upon the source of the allergens.
Employed to treat allergic rhinitis are mast cell stabilizers. In response to a challenge by an allergen, mast cells release mediators, which include, histamine, SRS-A, serotonin, adenosine, proteases, etc. which induce vasodilation, smooth muscle contraction, glandular secretion and stimulation of irritant nerve receptors among other symptoms. Mast cell stabilizers inhibit the release of mediators from the mast cells and thereby block the symptoms of their release.
Suitable mast cell stabilizers known or in use today include cromolyn sodium, nedocromil and lodoxamide. Each of these mast cell stabilizers may be topically applied.
Also employed to treat allergic rhinitis are nasal steroids, particularly the corticosteroids. Such steroids have powerful effects on immunologic and hormonal processes and are very effective in treating the inflammation which accompanies the allergic reaction. Suitable nasal steroids known in use today include beclamethasone, flunisolide, triamcinolone, dexamethasone and budesonide.
SUMMARY OF THE INVENTION
There is provided by the present invention a nasal spray or nasal drops forthe treatment of allergic rhinitis comprising:
a) an effective amount of a topical mast cell stabilizer to inhibit mast cell mediator release where said topical nasal mast cell stabilizer is selected from the group consisting of cromolyn sodium, nedocromil and lodoxamide;
b) an effective amount of a topical nasal steroid to reduce inflammation where said nasal steroid is selected from the group consisting of beclomethasone, flunisolide, triamcinolone, dexamethasone and budesonide; and
c) sterile water.
DETAILED DESCRIPTION OF THE INVENTION
The topical nasal mast cell stabilizers herein function by preventing degranulation of mast cells in response to allergens. When allergens are present, they bind to the immunoglobulin on the surface of mast cells and trigger the breakdown, or degranulation, of the cell. Upon degranulation, mast cell components, including mediators for symptoms associated with allergic rhinitis, are released. Person skilled in the art understand that only a sufficient amount of mast cell stabilizer should be administered to inhibit mast cell mediator release and no more. This amount will vary depending on whether cromolyn sodium, nedrocromiol or lodoxamide is employed. In the case of cromolyn sodium, from about 0.5 to about 20 mg, and preferably from about 3 to about 15 mg should be administered in this combination every 4 to 12 hours. In the case of nedocromil, from about 0.1 to about 20 mg, and preferably from about 2 to about 8 mg should be administered every 4 to 12 hours. Likewise, in the case of lodoxamide, from about 0.1 to about 30 mg, and preferably from about 2 to about 15 mg should be administered every 4 to 12 hours. To achieve these dosage ranges, cromolyn sodium should constitute the nasal spray or nasal drops composition from about 2 to about 80 mg/ml and preferably from about 10 to about 60 mg/ml. Nedocromil should constitute from about 1 to about 80 mg/ml and preferably from about 5 to about 30 mg/ml. Similary, lodoxamide should constitute from about 1 to about 100 mg/ml and preferably from about 5 to about 60 mg/ml.
Cromolyn sodium is also known as disodium cromoglycate or simply "cromolyn". This compound has been marketed under the names Ital and Lomudal (Cox et al., Adv. in Drug Res., 5:115-195 (1970)). Cromolyn is the disodium salt of 1 ,3-bis-(2-carboxy-chromone-5'-yloxy)-2-hydroxypropane. Cromolyn is believed to interface with the mechanism leading to a transiently elevated [Ca2+]j upon antigenic stimulation of the cell. Hence, it prevents histamine release. It has also been shown to inhibit degranulation and the antigen-induced 45Ca2+-influx to a certain degree (Cox, Nature, 216:1328 (1967); Mazurek, et al., Nature, 303:528(1983)). The manufacture of cromolyn is well known and has been described by Fitzmaurice, Lee, Brit. Pat. 1 ,144, 906.
Nedocromil as used herein inlcudes nedocromil and its pharmaceutically acceptable salts. The preferred salts are the sodium and calcium salts. Nedocromil, 9-ethyl-6,9-dihydro-4,6-dioxo-10-propyl-4H- pyrano[3,2-g] guinoline-2,8-dicarboxylic acid, inhibits the release and/or action of pharmacological mediators which result from the in vivo combination of certain types of antibodies and specific antigents, e.g. the combination of reaginic antibody with specific antigen (See Example 27 of Brit. Pat 1 ,292,601). The preparation of nedocromil is described in Brit. Pat. 2022078, U.S. Pat. 4,474,787 and Cairns et al., J. Med. Chem. 28, 1832 (1985).
Lodoxamide as used herein includes lodoxamide and its pharmaceutically acceptable salts and esters. The preferred salt of lodoxamide is its di-tris (hydroxymethyl) methyl ammonium (or bis THAM) salt and the preferred ester is the ethyl ester. Lodoxamide is known to inhibit the release of mast cell mediators of inflammation. The manufacture of lodoxamide, N,N'-(2-chloro-5-cyano-m-phenylene) dioxamic acid, is well known and taught in U.S. Pat. 3,962,308 and U.S. Pat. 3,993,679.
The topical nasal steroids for use herein are corticosteroids which inhibit the release of mediators for the symptoms associated with allergic rhinitis from mast cells and basophils. They also reduce inflammation and suppress neutrophil chemotaxis. The topical nasal steroids herein have relatively few side effects but are known to cause nasal irritation, drying and epistaxis with use of nasal sprays. Thus, persons skilled in the art understand that only a sufficient amount of nasal steroid should be administered to inhibit mast cell mediator release and inflammation and no more. This amount will vary depending on whether beclomethasone, flunisolide, triamcinolone, dexamethasone or budesonide is employed. Further, the nasal steroids are relatively long acting and alone can be administered once or twice daily. However, when used in conjunction with an active ingredient requiring more frequent administration, the amount of nasal steroid must be adjusted accordingly. For beclomethasone, from about 10 to about 100 meg, and preferably from about 15 to about 85 meg should be administered in this combination every 4 to 12 hours. To achieve these dosage ranges, the beclomethasone should constitute of the nasal spray or nasal drops composition from about 0.05 to about 0.5 mg/ml, and preferably from about 0.1 to about 0.3 mg/ml. For flunisolide, from about 30 to about 300 meg, and preferably from about 50 to about 200 meg should be administered in this combination every 4 to 12 hours. To achieve these dosage ranges, the flunisolide should constitute of the nasal spray or nasal drops composition from about 0.1 to about 1.0 mg/ml, and preferably from about 0.15 to about 0.5 mg/ml. For triamcinolone, from about 10 to about 100 meg, and preferably from about 15 to about 85 meg should be administered in this combination every 4 to 12 hours. To achieve these dosage ranges, the triamcinolone should constitute of the nasal spray or nasal drops composition from about 0.05 to about 0.5 mg/ml, and preferably from about 0.1 to about 0.3 mg/ml. For dexamethasone, from about 40 to about 400 meg, and preferably from about 60 to about 340 meg should be administered in this combination every 4 to 12 hours. To achieve these dosage ranges, the dexamethasone should constitute of the nasal spray or nasal drops composition from about 0.2 to about 2.0 mg/ml, and preferably from about 0.4 to about 1.2 mg/ml. For budesonide, from about 40 to about 400 meg, and preferably from about 60 to about 340 meg should be administered in this combination every 4 to 12 hours. To achieve these dosage ranges, the budesonide should constitute of the nasal spray or nasal drops composition from about 0.2 to about 2.0 mg/ml, and preferably from about 0.4 to about 1.2 mg/ml. The corticosteroid topical nasal steroids are, as a general matter, poorly soluble in water. Thus, they are administered in particulate form, as a micronized suspension in a suitable carrier/solvent system. For the treatment of the lung, it is desirable to produce aerosol particle sizes of less than 3 microns. However, in the instant case where it is desirable to treat nasal symptoms, the necessity of producing an aerosol of small particles is removed. For the present invention, it is only necessary to create a stable suspension of the corticosteroid in water which can be delivered by drops or spray directly into the nasal passages. The particle size of the corticosteroid in suspension is not critical so long as the particle is small enough that the amount of compound available for therapeutic activity is not surface area limited and the particle is stable in suspension. The suspension may be maintained with suitable liposomes. Preferably, however, the suspension is maintained by use of solubilizing agents and a suitable surfactant.
