Abstract
The present invention is drawn to adhesive formulations, methods of drug delivery, and solidified layers for dermal delivery of a drug. The formulation can include a drug, a solvent vehicle, and a solidifying agent. The solvent vehicle can have a volatile solvent system including at least one volatile solvent, and a non-volatile solvent system including at least two non-volatile solvents. The formulation can have a viscosity suitable for application to a skin surface prior to evaporation of the volatile solvents system. When applied to the skin, the formulation can form a solidified layer after at least a portion of the volatile solvent system is evaporated.
