Localized therapy of lower airways inflammatory disorders with proinflammatory cytokine inhibitors
Methods and compositions for treating inflammatory disorders of the lower airways are disclosed herein. In one aspect, a method for treating an inflammatory disorder of lower airways in a human subject in need thereof is disclosed, including administering directly to the lower airways in the human subject an effective amount of anakinra, where the effective amount of anakinra is 0.01 mg to 100 mg per day.
1. A method for treating an inflammatory disorder of lower airways in a human subject in need thereof, comprising administering directly to the lower airways in the human subject an effective amount of anakinra, wherein the effective amount of anakinra is 0.01 mg to 100 mg per day.
2. The method of claim 1 , wherein the inflammatory disorder of the lower airways is chronic obstructive pulmonary disease (COPD).
3. The method of claim 1 , wherein the inflammatory disorder of the lower airways is lung injury.
4. The method of claim 1 , wherein anakinra is administered via inhalation or via direct instillation into the lower airways.
5. The method of claim 1 , wherein the effective amount of anakinra is 0.1 mg to 50 mg per administration.
6. The method of claim 1 , wherein the effective amount of anakinra is 0.5 mg to 5.0 mg per administration.
7. The method of claim 1 , wherein the inflammatory disorder of the lower airways is cystic fibrosis.
8. The method of claim 1 , wherein the inflammatory disorder of the lower airways is bronchiolitis obliterans syndrome.
9. The method of claim 1 , wherein the inflammatory disorder of the lower airways is allograft rejection.
10. The method of claim 1 , wherein the method further includes administering a pharmaceutical carrier.
11. The method of claim 10 , wherein the pharmaceutical carrier is selected from the group consisting of saline, Ringer's solution, dextrose solution, and a combination thereof.
12. The method of claim 1 , wherein the method comprises administering two or more dosages of anakinra in less than 5 minutes apart.
13. The method of claim 1 , wherein the effective amount of anakinra is delivered using a device selected from the group consisting of a metered dose inhaler, a sprayer, a nebulizer, and a dry powder generator.
14. The method of claim 13 , wherein the effective amount of anakinra is delivered using a nebulizer.
15. The method of claim 14 , wherein the nebulizer is selected from the group consisting of an AERX Aradigm nebulizer, a Ultravent nebulizer (Mallinckrodt), and an Acorn II nebulizer.
16. The method of claim 13 , wherein the device releases a mixture containing anakinra and having an average particle size of less than 20 microns in diameter.
17. The method of claim 16 , wherein the device releases a mixture containing anakinra and having an average particle size of less than 10 microns in diameter.
18. The method of claim 17 , wherein the device releases a mixture containing anakinra and having an average particle size of less than 5 microns in diameter.
19. The method of claim 17 , wherein the device releases a mixture containing anakinra and having an average particle size of between 1 micron and 5 microns in diameter.
20. The method of claim 19 , wherein the device releases a mixture containing anakinra and having an average particle size of between 3 microns and 5 microns in diameter.
