Disposable dosage unit for iontophoresis-facilitated transdermal delivery, related devices and processes

摘要

Provided are disposable dosage units for use in iontophoresis-facilitated transdermal delivery which have hydrophilic polymer first and second layers, the first layer having ionic resin particles dispersed therein and the second layer having an ionized pharmaceutical contained. The second layer having on its surface a thin fabric layer bearing an adhesive layer. The polymer first and second layers are separated by a permselective membrane. Also provided are related devices and processes using the novel disposable dosage units.
