<p>A dermal drug delivery system is provided which comprises at least two components, for example, a sheet of a solid and flexible material, and a vehicle liquid comprising a solvent and optionally other ingredients. A drug can be impregnated in the sheet. Other ingredients, such as agents for fastening the drug on the sheet can also be impregnated in the sheet. These two components may be stored separately and joined either shortly before or at the time of application. To use the system, the vehicle liquid may be applied either on the target skin area or on the sheet, and the sheet may then be applied on the target skin area so that the vehicle liquid is positioned between the sheet and the skin and brought into contact with the ingredients impregnated in the sheet.</p> |
