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.

Abstract: A product retention package is disclosed, wherein the package is configured to form a sealed internal cavity for receiving a product, particularly transdermal delivery systems, patches, bandages, films, sheets, and the like. A retention apparatus is formed in association with the cavity to maintain the position of the product distal to a predetermined opening location. By controlling the position of the product within its packaging, the user can more easily and safely open the package at its predetermined opening location without damaging the product.

Abstract: A device and method for stabilizing a drug, particularly a chiral drug or the active enantiomer(s) thereof, in a carrier composition of a transdermal delivery system prior to the systems use by providing a product packaging system to prevent or control degradation reactions that can result from certain packaging materials and moisture contamination, while at the same time providing a child-resistant wrapping for the transdermal system.

Abstract: A method of and system for identifying an individual drug delivery device and tracing its ownership. An individual drug delivery device, such as a patch, is coded with a unique identifier. Such coding is performed by using a bar code or by storing the identifier in a memory device in the drug delivery device. A database contains a record of the identifier, representing the drug delivery device. The identifier is read upon a transfer of the drug delivery device and the database is updated to include information such as the date of the transfer, the identity of the transferee and the prescribing physician. The ability to retrieve such information regarding specific drug delivery devices can result in the prevention of abuse of controlled substances contained therein.

Abstract: Compositions and methods for the transdermal delivery of active agents up to a period of seven days or more at substantially a zero-order release rate comprising a pharmaceutically acceptable adhesive matrix and a polymeric plastic material that provides a release rate regulating effect on the active agents.

Abstract: A composition and method for the continuous and controlled transdermal delivery of an active agent comprising a pharmaceutically acceptable active agent carrier and cellulose derivative which provides a solubilizing and stabilizing effect on the active agents incorporated therein.

Abstract: A method and apparatus for making a patch comprising a foam supplier for supplying a foam backing having a predetermined porosity, a dispensing device for applying an ointment to the foam backing in a predetermined pattern, and a cooling device for cooling the foam backing prior to application of the ointment, wherein the ointment thickens and cures upon contact with the cooled foam backing.
