Claim:
1. A composition for the transdermal delivery of methylphenidate in the form of a flexible finite system for topical application consisting of a backing layer, a single skin-contacting polymer matrix layer, and, optionally, a release liner layer, wherein: the single skin-contacting polymer matrix layer consists essentially of: (a) methylphenidate and/or a pharmaceutically acceptable salt thereof; and (b) at least one non-reactive acrylic polymer that is polymerized from monomers including one or more monomers selected from the group consisting of methyl acrylate, methyl methacrylate, butyl acrylate, butyl methacrylate, hexyl acrylate, hexyl methacrylate, 2-ethylbutyl acrylate, 2-ethylbutyl methacrylate, isooctyl acrylate, isooctyl methacrylate, 2-ethylhexyl acrylate, 2-ethylhexyl methacrylate, decyl acrylate, decyl methacrylate, dodecyl acrylate, dodecyl methacrylate, tridecyl acrylate, tridecyl methacrylate, and amide group-containing monomers, wherein the polymer matrix is free of polymers with reactive functional groups and is free of silicone polymers.
