Abstract

The present invention relates generally to an electrotransport device (10) for transdermally or transmucosally delivering a beneficial agent (e.g., a drug) to the body surface of a patient or for transdermally or transmucosally sampling a body analyte. Most particularly, the present invention relates to a configured and electrochemically reactive electrode assembly (60) having improved start-up electrical performance and improved lag time to compliant agent delivery.
