The present invention is drawn to adhesive solidifying formulations, and methods for dermal delivery of a drug. The formulation can include a drug, a solvent vehicle, and a polyvinyl alcohol. The solvent vehicle can include a volatile solvent system including water and an alcohol solvent, e.g., ethanol, propanol, and/or isopropanol, and a non-volatile solvent system including at least one non-volatile solvent which is compatible with polyvinyl alcohol. The formulation is formulated such that the water to polyvinyl alcohol weight ratio is in the range of from about 4:1 to about 1:1, and water to alcohol solvent weight ratio in the range of from about 0.33:1 to about 6:1.
