ADI Product How-To: Skin Impedance Analysis Aids Active and Passive Transdermal Delivery
Transdermal drug-delivery methods offer a noninvasive delivery of medication through the patient's skin. Active delivery methods, which are described in this paper, use ultrasonic energy to speed up drug diffusion, using RF energy to create microchannels through the stratum corneum (outer layer of the epidermis), and iontophoresis.
