    • The present invention is drawn to adhesive peel-forming formulations for dermal delivery of a drug. The formulation can include a drug, a solvent vehicle, and a peel-forming agent. The solvent vehicle can include a volatile solvent system having one or more volatile solvent, and a non-volatile solvent system having one or more non-volatile solvent, wherein the non-volatile solvent system has a solubility for the drug that is within a window of operable solubility for the drug such that the drug can be delivered at therapeutically effective rates over a sustained period of time. 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 peelable layer after at least a portion of the volatile solvent system is evaporated.
    • 本发明涉及用于药物真皮递送的粘合剂剥离形成制剂。 制剂可以包括药物,溶剂载体和剥离形成剂。 溶剂载体可以包括具有一种或多种挥发性溶剂的挥发性溶剂体系和具有一种或多种非挥发性溶剂的非挥发性溶剂体系,其中所述非挥发性溶剂体系对于在窗口内的药物具有溶解性 对于药物具有可操作的溶解性,使得药物可以在持续的时间段内以治疗有效的速率递送。 在挥发性溶剂体系蒸发之前,配方可以具有适用于皮肤表面的粘度。 当施用于皮肤时,在挥发性溶剂系统的至少一部分蒸发之后,制剂可以形成固化的可剥离层。
