A transdermal delivery system is provided where the drug delivery rates, onset and profiles of at least one active agent are controlled by selectively manipulating the monomeric make up of an acrylic-based polymer in the transdermal drug delivery system. The drug carrier composition may be comprised of (a) one or more acrylic-based polymers having one or more different monomers selected from the group consisting of hard and soft monomers; (b) one or more silicone-based polymers; and (c) one or more active agents where the device provides a desired solubility for the active agent and controls drug delivery rates, onset and profiles of at least one active agent.
