Abstract
A polyacrylate formulation suitable for delivery of drug to through a body surface of an individual. By loading the drug and permeation enhancers at a high concentration into a polyacrylate proadhesive that has inadequate adhesive properties for typical adhesive application on the skin, a formulation with desirable adhesive characteristics and effective therapeutic properties can be made. The proadhesive has higher glass transition temperature than typical pressure sensitive adhesives.
