Method of treating rhinitis with C-type natriuretic peptides
View Patent ↗The problem to be solved by the present invention is to provide an effective and safe therapeutic preparation for rhinitis, which not only has significant effects on improvement in rhinitis, in particular allergic rhinitis, but also is rapid in manifestation of efficacy, fast-acting, and long-lasting, without local side effects. Means for solving the problem is a therapeutic preparation for rhinitis, in particular allergic rhinitis, comprising C-type natriuretic peptide (CNP) or B-type natriuretic peptide (BNP) as the active ingredient.
1. A method of treating rhinitis, the method comprising applying a composition that comprises an effective amount of C-type natriuretic peptide (CNP) to a nasal cavity or nostril of a subject in need of such treatment,
wherein the CNP is selected from the group consisting of CNP-22 and CNP-53, wherein the amino acid sequence of CNP-22 is SEQ ID NO: 1 and the amino acid sequence of CNP-53 is SEQ ID NO:22.
2. The method of treating rhinitis according to claim 1 , wherein the concentration of the CNP is 20-200 μg/g weight of the composition.
3. The method of treating rhinitis according to claim 1 , wherein the concentration of the CNP is 50-200 μg/g weight of the composition.
4. The method of treating rhinitis according to claim 1 , wherein the concentration of the CNP is 50-100 μg/g weight of the composition.
5. The method of treating rhinitis according to claim 1 , wherein the rhinitis is infectious rhinitis, hypersensitive non-infectious rhinitis, irritant rhinitis, atrophic rhinitis, or specific granulomatous rhinitis.
6. The method of treating rhinitis according to claim 5 , wherein the infectious rhinitis is acute rhinitis or chronic rhinitis.
7. The method of treating rhinitis according to claim 5 , wherein the hypersensitive non-infectious rhinitis is combined-type rhinitis (hypersensitive nose), rhinorrhea-type rhinitis, congestive-type rhinitis, or dry-type rhinitis.
8. The method of treating rhinitis according to claim 7 , wherein the combined-type rhinitis (hypersensitive nose) is allergic rhinitis.
9. The method of treating rhinitis according to claim 8 , wherein the allergic rhinitis is allergic rhinitis against at least one allergen selected from the group consisting of house dust, mite, cedar, orchard grass, ragweed, and cat hair.
10. The method of treating rhinitis according to claim 5 , wherein the irritant rhinitis is physical irritant-induced rhinitis, chemical irritant-induced rhinitis or radiation-induced rhinitis.
11. The method of treating rhinitis according to claim 1 , wherein the rhinitis is atrophic rhinitis or specific granulomatous rhinitis.
12. The method of treating rhinitis according to claim 1 , wherein the rhinitis is mixed-type rhinitis, sneezing/rhinorrhea-type rhinitis, or nasal-occlusion-type rhinitis.
13. The method of treating rhinitis according to claim 1 , wherein the composition is selected from an ointment preparation, a gel preparation, a cream preparation, a lotion preparation, a liquid preparation, a powder preparation or a spray preparation.
14. The method of treating rhinitis according to claim 13 , wherein the composition is selected from a gel preparation, a liquid preparation or a spray preparation.
15. The method of treating rhinitis according to claim 1 , wherein the rhinitis is rhinitis in a subject suffering from atopic dermatitis.
16. The method of treating rhinitis according to claim 1 , wherein the rhinitis is rhinitis with treatment resistance to steroids.
17. The method of treating rhinitis according to claim 1 , wherein the rhinitis is rhinitis in a subject having a difficulty in withdrawal from steroids.
18. The method of treating rhinitis according to claim 1 , wherein the rhinitis is rhinitis with treatment resistance to antihistamine drugs.
