Webcurrent although alternating currents or more complex current waveforms have also been used (Meyer and Oddsson, 2003; Reinauer et al., 1993). Current densities of up to 0.5 mA/cm2 are considered safe (Ledger, 1992) but in practice current densities vary between 0.005 – 0.2 mA/cm2. Figure 2. Transdermal iontophoresis in practice. WebDEX-P iontophoresis is generally provided by two widely cited animal, ie, monkey and pig, studies. 11-12 Unfortunately, these iontophoretic studies used methodology or measured endpoints that are not relevant to current clinical iontophor-esis. These studies were also widely disparate in measured DEX/DEX-P delivery amounts. Glass et al 11 ...

WebHow does iontophoresis work? During treatment, the iontophoresis device is plugged into a power source (an outlet), which delivers a mild electrical current to the treatment area, using the minerals found in tap water as a conductor. The current reaches the skin, which is slightly covered in water, through the conductive metal electrodes.
