| Application Number: | US15353301 |
| Patent Claims: | 1. A method of treating a skin ailment in a subject , the method comprising:administering to a subject a topical composition comprising nitric oxide-releasing polysiloxane macromolecules anda hydrophobic, non-aqueous gel base, the hydrophobic, non-aqueous gel base comprising mineral oil, wherein the nitric oxide (NO) storage per gram is in a range of 100 nmol NO/g to 1 mmol NO/g of the topical composition and at least 70% of NO of the nitric oxide-releasing polysiloxane macromolecule remains in the topical composition two days after initial formulation when the topical composition is stored at room temperature.2. The method of claim 1 , wherein the nitric oxide-releasing polysiloxane macromolecules are diazeniumdiolate-functionalized polysiloxane macromolecules.3. The method of claim 1 , wherein the method decreases inflammation in the subject.4. The method of claim 1 , wherein the method decreases inflammatory response factors in the subject.5. The method of claim 1 , wherein the method modulates inflammatory cytokines in the subject.6. The method of claim 1 , wherein the skin ailment is an inflammatory skin condition.7. The method of claim 1 , wherein the skin ailment is impetigo claim 1 , psoriasis claim 1 , tinea pedis claim 1 , or onychomycosis.8. The method of claim 1 , wherein the topical composition is antimicrobial.9. The method of claim 1 , wherein the topical composition disperses a biofilm.10. The method of claim 1 , wherein the topical composition disrupts the structure of the biofilm and/or prevents biofilm formation.11. The method of claim 1 , wherein the topical composition kills bacteria present in a biofilm.12. A method of treating a skin ailment in a subject claim 1 , the method comprising:administering to a subject a topical composition comprising nitric oxide-releasing polysiloxane macromolecules and a hydrophilic gel base, the hydrophilic gel base comprising an alcohol, wherein the nitric oxide (NO) storage per gram is in a range of 100 nmol NO/g to 1 mmol NO/g of the topical composition and at least 70% of NO of the nitric oxide-releasing polysiloxane macromolecule remains in the topical composition two days after initial formulation when the topical composition is stored at room temperature.13. The method of claim 12 , wherein the nitric oxide-releasing polysiloxane macromolecules are diazeniumdiolate-functionalized polysiloxane macromolecules.14. The method of claim 12 , wherein the method decreases inflammation in the subject.15. The method of claim 12 , wherein the method decreases inflammatory response factors in the subject.16. The method of claim 12 , wherein the method modulates inflammatory cytokines in the subject.17. The method of claim 12 , wherein the skin ailment is an inflammatory skin condition.18. The method of claim 12 , wherein the skin ailment is impetigo claim 12 , psoriasis claim 12 , tinea pedis claim 12 , or onychomycosis.19. The method of claim 12 , wherein the topical composition is antimicrobial.20. The method of claim 12 , wherein the topical composition disperses a biofilm.21. The method of claim 12 , wherein the topical composition disrupts the structure of the biofilm and/or prevents biofilm formation.22. The method of claim 12 , wherein the topical composition kills bacteria present in a biofilm. |
