ABSTRACT:
A device is disclosed for administration of an active agent to a host, e.g., for transdermal administration. The device includes an impermeable adhesive layer which surrounds the permeable adhesive layer of the device and which with the outer surface layer of the device forms a pocket so that, when the device is adhered to the skin or mucosa, the active agent can be released to the skin or mucosa to provide a continuous dose of the active agent to the skin or mucosa but cannot permeate through the outer surface layer or radially outwardly through the active agent impermeable adhesive layer.
