Gel formulations for topical drug release

摘要

Invention Patent: B '' GEL FORMULATIONS FOR TOPICAL DRUG RELEASE ''. Pharmaceutical gel formulations for topical drug release include drugs, colloidal silicon dioxide, triacetin and, preferably, propylene glycol. Gel formulations are well suited for the topical release of the drug 4-amino-2-ethoxymethyl- 244, 244 -dimethyl-1H-imidazo [4,5-c] quinoline -1-ethanol, which when applied topically induces cytokines, such as interferon and tumor necrosis factor, locally on the skin or on mucous membranes of a mammal. Gel formulations are also well suited for topical release of drugs for treating diseases involving lesions on the skin and / or mucous membranes due to the fact that gel formulations do not need to include irritating components.
