First claim

Opening claim text (preview).

The invention claimed is: 1. A method for treating an allergic symptom or disorder in a subject in need thereof, comprising: nasally administering by a pump sprayer to the subject a solution comprising a therapeutically effective amount of budesonide, SAE-CD, an antihistamine, and a pharmaceutically acceptable aqueous liquid carrier, wherein the molar ratio of SAE-CD to budesonide is about 47:1, wherein the budesonide is present in an amount of about 30 μg per unit dose, and wherein the antihistamine is present in an amount of about 137 μg per unit dose; wherein the therapeutically effective amount is administered in one unit dose per nostril; wherein the antihistamine is azelastine or a pharmaceutically acceptable salt thereof; wherein the SAE-CD is sulfobutylether β-cyclodextrin; and wherein the method provides more rapid relief from the allergy symptom or disorder compared to a budesonide suspension at the same unit dose. 2. The method of claim 1 , wherein the allergic symptom or disorder includes a non-nasal symptom selected from the group consisting of: itchy or gritty eyes, tearing or watery eyes, red or burning eyes, itchy ears or palate, and combinations thereof. 3. The method of claim 1 , wherein the allergic symptom or disorder further comprises symptoms selected from the group consisting of runny nose, itchy nose, nasal congestion, sneezing and combinations thereof. 4. The method of claim 1 , wherein the solution is administered to the subject 1-2 times per day. 5. A method for treating an ocular symptom or disorder in a subject in need thereof, comprising: nasally administering by a pump sprayer to the subject a solution comprising a therapeutically effective amount of budesonide, SAE-CD, an antihistamine and a pharmaceutically acceptable aqueous liquid carrier, wherein the molar ratio of SAE-CD to budesonide is about 47:1, wherein the budesonide is present in an amount of about 30 μg per unit dose, and wherein the antihistamine is present in an amount of about 137 μg per unit dose; wherein the therapeutically effective amount is administered in one unit dose per nostril; wherein the antihistamine is azelastine or a pharmaceutically acceptable salt thereof; wherein the SAE-CD is sulfobutylether β-cyclodextrin; wherein the method provides more rapid relief from the ocular symptom or disorder compared to a budesonide suspension at the same unit dose. 6. The method of claim 5 , wherein the ocular symptom or disorder includes a non-nasal symptom selected from the group consisting of itchy or gritty eyes, tearing or watery eyes, red or burning eyes, itchy ears or palate, and combinations thereof. 7. The method of claim 5 , wherein the solution is administered to the subject 1-2 times per day. 8. A method for treating ocular inflammation in a subject in need thereof, comprising: ophthalmically administering to the subject a solution comprising a therapeutically effective amount of budesonide, SAE-CD, an antihistamine and a pharmaceutically acceptable aqueous liquid carrier, wherein the molar ratio of SAE-CD to budesonide is about 47:1, wherein the budesonide is present in an amount of about 30 μg per unit dose, and wherein the antihistamine is present in an amount of about 137 μg per unit dose; wherein the therapeutically effective amount is administered in one unit dose per nostril; wherein the budesonide solution provides more rapid reduction in ocular inflammation compared with a budesonide suspension at the same unit dose; wherein the SAE-CD is sulfobutylether β-cyclodextrin; wherein the antihistamine is azelastine or a pharmaceutically acceptable salt thereof. 9. The method of claim 8 , wherein the solution is administered to the subject 1-2 times per day.
