Abstract:
1. An adhesive peel-forming formulation for dermal delivery of a drug, comprising: a) a drug, wherein the drug comprises less than 10 wt % of the formulation; b) a solvent vehicle, comprising: c) a peel-forming agent, wherein the peel-forming agent comprises 20.8 wt % to 40.9 wt % of the formulation excluding the drug, wherein the formulation has a viscosity suitable for application ranging from 1,000 cPs to 1,000,000 cPs, and adhesion to a skin surface prior to evaporation of the volatile solvent system, wherein the formulation applied to the skin surface forms a coherent and soft solidified peelable layer without a backing after at least partial evaporation of the volatile solvent system, and wherein the drug continues to be delivered after the volatile solvent system is substantially evaporated, and wherein the solidified peelable layer has sufficient tensile strength so that it can be peeled off the skin in one piece or several large pieces.
