Abstract

The combination of several synergistic antioxidants, enzymatic co-factors and amino acids in appropriate delivery vehicles employed in aerosol carriers, mist and pump oral sprays, solutions, such as oral irrigators, mouth rinses and mouthwashes, or gels and solid compositions as a means of preventing and ameliorating signs and symptoms and complications to the oro-pharyngeal cavity and mouth including buccal mucosa, gums and tongue and the upper respiratory tract from damage caused by free radical species induced by tobacco smoke, smokeless tobacco, ingested or chewed noxious, malodorous or harmful substances and other inhaled environmental pollutants and particulate matter, including tobacco to secondary smokers.

Claims

1. A method for reducing free radical damage induced by tobacco products and environmental pollutants comprising administering in a suitable carrier in concentrations for effectively reducing said free radical damage to the oro-pharynx and upper respiratory tract of a user a combination of from 0.01 and 10% (weight) glutathione, from 1.0 to 25% (weight) ascorbic acid, from 0.001 to 10% (weight) of a source of selenium and from 0.001 to 2.0% (weight) of a sulphur containing amino acid.

2. The method of claim 1 wherein said combination and carrier are introduced to the oro-pharynx and upper respiratory tract of a user by use of an intranasal vapor inhaler or humidifiers, steam inhalers or oral dental irrigators.

3. The method of claim 1 wherein said combination and carrier are introduced to the oro-pharynx and upper respiratory tract of a user by use of an intra-oral spray.

4. The method of claim 1 wherein said combination and carrier are introduced to the oro-pharynx and upper respiratory tract of a user by use of an aerosol.

5. The method of claim 1 wherein said combination and carrier are introduced to the oro-pharynx and upper respiratory tract of a user by use of a stream inhaler, nebulizer or vaporizer.

6. The method of claim 1 wherein said source of selenium comprises a member selected from the group consisting of elemental selenium and selenomethionine.

7. The method of claim 1 wherein said sulphur containing amino acid comprises a member selected for the group consisting of L-cysteine and L-methionine.

8. The method of claim 1 wherein said combination further comprises between 0.1 and 5.0% (weight) D, L-alpha tocopherol acetate based upon the total weight of said combination.
