ABSTRACT:
A method for making transdermal drug delivery devices is provided which includes: laminating an adsorbent source layer to a pressure-sensitive, pharmaceutically acceptable contact adhesive; depositing a drug in liquid form on one face of the source layer; laminating an anchor adhesive layer to the opposing face of the source layer; and applying a drug-impermeable backing layer to the anchor adhesive, which backing layer then defines the upper surface of the device. The invention also encompasses transdermal drug delivery devices having a source layer in contact with and contained between anchor and contact adhesive layers, with a backing layer adjacent the anchor adhesive defining the upper surface of the device.
