The IontoPatch contains an innovative self-contained battery that produces an electric current to carry drug molecules non-invasively across the skin and to underlying tissue. There is no need for an external power source. Drug delivery is shut off automatically when the prescribed dosage has been administered. The IontoPatch is single use and disposable. Since there are no external batteries or wires, patients are able to return to their daily activities wearing the patch and receiving time-released iontophoresis.
