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.
1 . A method for preventing or treating inflammation in an airway of a patient in need thereof, comprising the step of
administering to said airway of said patient a formulation comprising dapsone, wherein said formulation is an aerosolized formulation or an aqueous formulation.
2 . The method of claim 1 , wherein said formulation is an aerosolized formulation and said step of administering is carried out using a device selected from the group consisting of a metered-dose inhaler and a dry powder inhaler.
3 . The method of claim 1 , wherein said formulation is an aqueous formulation and said step of administering is carried out via installation.
4 . The method of claim 1 , 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.
5 . A method of preventing or treating abnormal mucociliary transport in an airway of a patient in need thereof, comprising the step of
administering to said airway of said patient a formulation comprising dapsone, wherein said formulation is an aerosolized formulation or an aqueous formulation.
6 . The method of claim 5 , wherein said formulation is an aerosolized formulation and said step of administering is carried out using a device selected from the group consisting of a metered-dose inhaler and a dry powder inhaler.
7 . The method of claim 5 , wherein said formulation is an aqueous formulation and said step of administering is carried out via installation.
8 . The method of claim 5 , 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.
