1. An inhalable composition comprising about 250 μ
- g or less of a single corticosteroid, a solvent and a solubility enhancer, wherein upon administration of the composition to a subject through a device, the composition achieves a rate of increasing concentration of the corticosteroid inside the device of about 5 μ
g/ml per minute or less over administration of the corticosteroid through the device, and wherein the composition is substantially free of active pharmaceutical agents other than the corticosteroid.

Abstract
The present invention relates to methods and systems for the delivery of a corticosteroid comprising (1) an inhalable aqueous mixture comprising a corticosteroid and a solubility enhancer and (2) an inhalable nebulizer, wherein the delivery of the aqueous mixture comprising the corticosteroid by the nebulizer results in an enhanced pharmacokinetic profile of the corticosteroid as compared to conventional inhalable therapies and/or increase lung deposition.
