Aerosolized Dapsone as a Therapy for Inflammation of the Airway and Abnormal Mucociliary Transport
Aerosolized dapsone (or alternatively, an aqueous formulation of dapsone) is used to treat airway inflammation, particularly chronic neutrophil-dominated inflammation. Diseases that may be prevented or treated by the methods include chronic obstructive pulmonary diseases (COPDs), asthma, cystic fibrosis, and others.

9 . A method of treating inflammation in an airway of a patient in need thereof, comprising administering to said airway of said patient a pharmaceutical composition comprising dapsone and a pharmaceutically acceptable carrier suitable for use in inhalation, wherein said pharmaceutical composition is an aerosolized composition and said administration is carried out using a device selected from the group consisting of a metered-dose inhaler and a dry powder inhaler.
10 . The method of claim 9 , wherein the inflammation comprises abnormal mucociliary transport.
11 . The method of claim 9 , wherein said patient is suffering from a disease or condition selected from the group consisting of cystic fibrosis, bronchiectasis, bronchiolitis obliterans, emphysema, chronic bronchitis, chronic rhinosinusitis, toxic inhalation injury, chronic obstructive pulmonary disease, idiopathic pulmonary fibrosis, asthma, and chronic airway inflammation.
12 . The method of claim 9 , wherein the pharmaceutical composition is administered once per day.
13 . The method of claim 9 , wherein the pharmaceutical composition is administered two to twelve times per day in approximately equally timed doses.
14 . The method of claim 9 , wherein the pharmaceutical composition is administered twice per day.
15 . The method of claim 9 , wherein the pharmaceutical composition is administered three times per day.

18 . The method of claim 9 , wherein the pharmaceutical composition is given in a dosage of about 0.5 mg/kg of body weight to about 5.0 mg/kg of body weight, per dose.
19 . The method of claim 9 , wherein the pharmaceutical composition is given in a dosage of about 1.0 mg/kg of body weight to about 4.0 mg/kg of body weight, per dose.

21 . The method of claim 9 , wherein the pharmaceutical composition is given in a dosage of about 2.0 mg/kg of body weight per dose.
22 . A method of treating inflammation in an airway of a patient in need thereof, comprising administering to said airway of said patient a pharmaceutical composition comprising dapsone and a pharmaceutically acceptable carrier suitable for use in inhalation, wherein said pharmaceutical composition is an aqueous composition suitable for aerosolization and said administration is carried out by inhalation of said aqueous composition suitable for aerosolization.
23 . The method of claim 22 , wherein the inflammation comprises abnormal mucociliary transport.
24 . The method of claim 22 , wherein said patient is suffering from a disease or condition selected from the group consisting of cystic fibrosis, bronchiectasis, bronchiolitis obliterans, emphysema, chronic bronchitis, chronic rhinosinusitis, toxic inhalation injury, chronic obstructive pulmonary disease, idiopathic pulmonary fibrosis, asthma, and chronic airway inflammation.
25 . The method of claim 22 , wherein the pharmaceutical composition is administered once per day.
26 . The method of claim 22 , wherein the pharmaceutical composition is administered two to twelve times per day in approximately equally timed doses.
27 . The method of claim 22 , wherein the pharmaceutical composition is administered twice per day.
28 . The method of claim 22 , wherein the pharmaceutical composition is administered three times per day.
29 . The method of claim 22 , wherein the pharmaceutical composition is administered four times per day.
30 . The method of claim 22 , wherein the pharmaceutical composition is administered five or more times per day.
31 . The method of claim 22 , wherein the pharmaceutical composition is given in a dosage of about 0.5 mg/kg of body weight to about 5.0 mg/kg of body weight, per dose.
32 . The method of claim 22 , wherein the pharmaceutical composition is given in a dosage of about 1.0 mg/kg of body weight to about 4.0 mg/kg of body weight, per dose.
33 . The method of claim 22 , wherein the pharmaceutical composition is given in a dosage of about 1.5 mg/kg of body weight to about 3.0 mg/kg of body weight, per dose.
34 . The method of claim 22 , wherein the pharmaceutical composition is given in a dosage of about 2.0 mg/kg of body weight per dose.
35 . A pharmaceutical composition for administration by inhalation for treating inflammation in an airway of a patient in need thereof comprising a therapeutically effective amount of dapsone and a pharmaceutically acceptable carrier suitable for use in inhalation, wherein said composition is a dry powder composition suitable for use in a metered dose inhaler or dry powder inhaler.
36 . A pharmaceutical composition for administration by inhalation for treating inflammation in an airway of a patient in need thereof comprising a therapeutically effective amount of dapsone and a pharmaceutically acceptable carrier suitable for use in inhalation, wherein the composition is an aqueous solution.
