Abstract:
1. An agent-containing reservoir for incorporation into an electrotransport delivery system adapted to be placed in agent-transmitting contact with a subject body surface for delivering the agent through the body surface by means of an electrotransport current (i) applied to the reservoir via a reservoir-contacting electrode, the reservoir being permeable to electrically assisted flux of the agent and having: (a) a predetermined volume that holds a quantity of the agent sufficient to achieve therapeutically effective delivery of the agent during the entire intended duration of use, wherein the predetermined volume for a given reservoir thickness is defined by the reservoir average cross-sectional area A (b) a surface that is placed in contact with the body of the subject during use, the body-contacting surface having an area A (c) a surface in contact with the electrode, the electrode-contacting surface having an area A
