Iontophoretic Application of Acyclovir Gel to Treat Cold Sores

Summary

Currently approved drugs for the treatment of herpes labialis (cold sores) exhibit low levels of efficacy due to the limited ability of the drugs to penetrate the skin to the sites where the herpes virus is replicating. Iontophoresis uses electric current to enhance delivery of drugs through the skin. This trial is testing a new iontophoretic device with a new acyclovir gel to treat cold sores.
