摘要:A graft copolymer for use as an adhesive for drug delivery patches or dressingsthat is resistant to dissolution in the presence of skin penetration enhancers comprisescopolymerized acrylic and, optionally, vinyl monomers, to form a backbone polymer, towhich are grafted polymeric moieties that do not absorb greater than 3% by weight of askin- penetration enhancer under thermodynamic equilibrium at 25° C. if independentlyintroduced into an excess of the enhancer. Preferably, the grafted polymers are selectedfrom the classes of polybutylene, polysaccharide, poly(ethyleneoxide/propyleneoxide),and polyamide polymers, and specific grafted polymers will depend on the specificenhancers used in a particular drug delivery system.
