ABSTRACT:
A transdermal drug delivery device for topical application of active agents is disclosed. The invention comprises the use of a flexible and soft backing layer, in particular a cellular foam, having an inner surface and an outer surface, wherein an impermeable polymeric barrier film is affixed to its inner surface. The barrier film functions to anchor and support an active agent carrier composition disposed thereon, and to prevent passage of such composition into the backing layer. The system provides excellent flexibility and conformability for topical application to sites subject to frequent movement or which are greatly contoured. Methods of use are also disclosed.
