Which of the following is a pro of phonophoresis?

• A. Spreads over a large area
• B. Not systemic
• C. Noninvasive
• D. All of the above

Answer: (D)

Phonophoresis uses ultrasound to push a topical medication through the skin, enhancing its absorption. This brings several practical advantages. Because it delivers the drug through the skin without needling, it is noninvasive. The ultrasound can drive the medication over a broader treated area rather than just a single spot, expanding the region that benefits from the therapy. And with the drug entering mainly through the skin rather than being taken orally or injected, systemic exposure tends to be reduced, lowering the risk of systemic side effects. When you combine these benefits—coverage over a wider area, noninvasive administration, and lower systemic exposure—it makes sense that all of these are considered pros of phonophoresis.
