The present invention provides an inhalable formulation containing SAE-CD and a corticosteroid. The formulations are suitable for administration to the subject by spraying with any known nebulizer. Formulations may be included in a kit. The formulations are administered as an aqueous solution, but may be stored as a dry powder, an already prepared solution, or a concentrated composition. The formulations are used in an improved spray system for administering corticosteroids by inhalation. The SAE-CD present in the formulation significantly improves the chemical stability of the wasesonide. The present invention provides a method of administering a formulation by inhalation. The formulations may also be administered by conventional nasal delivery devices. |
