Abstract

An inhalable formulation containing SEA-gamma-CD and corticosteroid is provided. The formulation is adapted for administration to a subject by nebulization with any known nebulizer. The formulation can be included in a kit. The formulation is administered as an aqueous solution, however, it can be stored as a dry powder, ready-to-use solution, or concentrated composition. The formulation is employed in an improved nebulization system for administering corticosteroid by inhalation. SAE-gamma-CD present in the formulation significantly enhances the chemical stability of budesonide. A method of administering the formulation by inhalation is provided. The formulation can also be administered by conventional nasal delivery apparatus.

Description

Inhalation formulations containing sulfoalkyl ether cyclodextrins and corticosteroids Inventors: JamesD.Pipkin, RupertO.Zimmerer, DianeO.Thompson, GeroldL.Mosher technical field The present invention relates to a method and formulation for administering sulfoalkyl ether cyclodextrins and corticosteroids such as budesonide by inhalation. The present invention also relates to methods of treating pulmonary diseases and conditions. Background technique Drug delivery by inhalation results in drug deposition in various parts of the respiratory tract, such as the throat, trachea, bronchi, and alveoli. In general, the smaller the particle size, the longer the particles remain suspended in the air, so the drug can be delivered deeper into the respiratory tract. Corticosteroids are delivered by inhalation using a nebulizer, metered dose inhaler, or dry powder inhaler. The main advantages of nebulizers are that they do not require patient cooperation and are simpler to deliver hi...
