Iontophoresis is used to deliver what therapeutic effect locally?

• A. Local anesthetic
• B. Systemic analgesic
• C. Muscle growth stimulant
• D. Heat therapy

Answer: (A)

Iontophoresis uses an electrical current to push charged drug molecules through the skin to produce a local effect at the treatment site. This makes it well suited for delivering a local anesthetic, which temporarily numbs nerves in the targeted area to reduce pain during procedures or rehab. The goal here is localized relief rather than distributing the drug systemically, which is why systemic analgesia wouldn’t be the intended outcome. Heat therapy or muscle growth stimulation aren’t achieved by delivering a drug this way, so they aren’t what iontophoresis is used for.
