Phonophoresis uses ultrasound to enhance absorption of which substances?

Phonophoresis uses ultrasound to enhance absorption of which substances?

• A. Anti-inflammatory drugs and local analgesics
• B. Antibiotics only
• C. Vasodilators
• D. Anesthetic gases

Answer: (A)

Phonophoresis uses ultrasound to temporarily increase skin permeability, allowing topical drugs to diffuse more deeply into underlying tissues. This makes anti-inflammatory medications and local analgesics especially well-suited for this modality, as they can reach the site of inflammation or pain and exert their effects more effectively. That’s why anti-inflammatory drugs (to reduce inflammation) and local analgesics (to numb the area) are the typical choices enhanced by this technique. Antibiotics have been explored in some studies, but they’re not the standard agents used with phonophoresis. Vasodilators and anesthetic gases are not the common substances delivered this way, either.
