In particular, described herein are electtotransport drug delivery systems includ - ing constant current delivery systems having a feedback current and/or voltage control module that is isolated from the patient con - tacts (e.g., anodes and cathodes). The feedback module may be isolated by a transistor from the patient contacts; feedback current and/or voltage control measurements may be performed at the transistor rather than the at patient contact (e.g., cathode).
