Iontophoresis is defined as what?

• A. Transcutaneous delivery of ions into the body for therapeutic purposes using an electrical current.
• B. Application of heat to tissues
• C. Delivery of nutrients via patch
• D. Electrical stimulation without ions

Answer: (A)

Iontophoresis uses a mild electrical current to push charged drug ions through the skin into underlying tissues for therapeutic effect. It’s a transcutaneous delivery method that relies on electromigration—the same-charged electrode repels the drug ions into the body, so the drug must be ionized to move under the current. This is different from simply applying heat, delivering nutrients passively via a patch, or providing electrical stimulation without moving ions through the skin.
