Abstract

An electrotransport system (50) includes a reusable controller (52) having a power source (60) and a separable disposable drug-containing unit (70). The controller (52) contains a switch (62) which disconnects the power source (60) from current drain when the controller (52) is uncoupled from the drug unit (70). A coupling means (74, 66, 105, 72, 64, 104) physically and electrically connects together the controller (52) and the drug unit (70) such that the controller (52) provides electrical current to the drug unit (70) for electrotransport delivery of the drug to a body surface (e.g., the skin) of a patient.
