ABSTRACT:
The disclosed invention relates to an improved electrotransport device. The improvement relates to a membrane assembly including a low porosity membrane adhered or sealed to one or two high porosity membranes. The high porosity membranes protect the low porosity membrane from being damaged by components or contaminates on the body surface and/or in the drug reservoir which can lead to undesirable passive flux and/or insufficient iontophoretic flux. As a result, the electrotransport device having the membrane assembly more reliably, precisely, and accurately delivers drug and/or therapeutic agent through the body surface by electrotransport.
