The introducer has a drug-providing portion, and the applicator has current-generating element to pass through it an electrical current. Passing an electrical current through the drug-providing portion causes the drug to eject into treated tissue.Also disclosed are charged drugs suitable for iontophoretic administration, which include a bioactive agent encapsulated in charged nano-particles.
