An iontophoresis device (10) includes a membrane applied to said skin having a drug delivery aperture, a solvent delivery aperture and a vent aperture for applying a vacuum between the membrane and skin. A drug cartridge defines a drug containing chamber in communication with the drug delivery aperture and a drug air chamber separated by a first flexible membrane. A solvent cartridge defines a solvent containing chamber and a solvent air chamber separated by a second flexible membrane. An electrode is positioned between the membrane and the skin and surrounds the drug delivery aperture and the solvent delivery aperture. A drug cartridge may also include two separate chambers, one containing a lyophilized agent, the other containing a solvent. The solvent and the agent remain separate until mixed during operation of the device.
