A transdermal medication delivery system in which the active drug that is administered to the patient is combined with the agent that holds or adheres the delivery system to the skin. DIA patches are thinner than patches in which the adhesive and active drug layers are separated. They fit the skin more closely and with less bulk than alternative transdermal delivery systems.
