Abstract
The present invention is drawn to sprayable formulations, methods of drug delivery, and resultant solidified layers for dermal delivery of a drug. The formulation can include a drug, a non-volatile solvent system, a solidifying agent, and a propellant. The formulation can have an initial viscosity suitable to be expelled out of a pressurized or manual pump container and applied onto a skin surface as a layer. When applied to the skin, the formulation can form a solidified layer after at least a portion of the propellant is evaporated.
