First claim

Opening claim text (preview).

That which is claimed is: 1. An anhydrous topical pharmaceutical composition comprising: hydroxypropyl cellulose present in the composition at a concentration in a range of 0.1% to 15% by weight of the anhydrous topical pharmaceutical composition; ethyl alcohol or isopropyl alcohol present in the composition at a concentration in a range of 45% to 95% by weight of the anhydrous topical pharmaceutical composition; hexylene glycol present in the composition at a concentration in a range of 1% to 20% by weight of the anhydrous topical pharmaceutical composition; cyclomethicone present in the composition at a concentration in a range of 0.5% to 15% by weight of the anhydrous topical pharmaceutical composition; and a diazeniumdiolated co-condensed silica particle at a concentration in a range of 0.1% to 40% by weight of the anhydrous topical pharmaceutical composition. 2. The anhydrous topical pharmaceutical composition of claim 1 , wherein the diazeniumdiolated co-condensed silica particle has a mean particle size of less than 10 μm. 3. The anhydrous topical pharmaceutical composition of claim 1 , wherein the composition is packaged and the packaged composition has a shelf life of at least four weeks. 4. The anhydrous topical pharmaceutical composition of claim 3 , wherein the shelf life is under refrigerated conditions. 5. The anhydrous topical pharmaceutical composition of claim 3 , wherein the shelf life is at least 52 weeks. 6. A method of treating a dermatological condition comprising applying the anhydrous topical pharmaceutical composition of claim 1 to the skin of a patient to treat the dermatological condition. 7. The method of claim 6 , wherein the dermatological condition comprises acne.
