Claim 1
Independent Claim 31 words
An effective amount of reduced Glutathione (GSH) in a pharmaceutically acceptable carrier, in the form of an aerosol suitable for administration by inhalation, for augmenting the GSH level in the lungs.
Claim 2
Dependent Claim 31 words
An effective amount of reduced Glutathione (GSH) in a pharmaceutically acceptable carrier, in the form of an aerosol suitable for administration by inhalation, for augmenting the GSH level in the lungs.
Claim 3
