Which Sonic technology utilizes high-frequency sound waves to deliver medication?

Sonophoresis is the correct choice because this technology specifically utilizes high-frequency sound waves to facilitate the transdermal delivery of medications. The ultrasonic waves created during sonophoresis enhance the permeability of the skin, allowing for larger molecules to pass through into the bloodstream more effectively than they would through normal application methods. This technique is particularly beneficial in administering drugs that typically have low bioavailability when delivered topically.

In contrast, cavitation therapy involves the formation and collapse of bubbles in liquids, which can create mechanical forces used for various therapeutic purposes but does not specifically relate to the delivery of medication. Thermotherapy focuses on the application of heat for therapeutic effects and does not incorporate sound waves for medication delivery. Lymphatic drainage therapy employs manual techniques to encourage lymph flow, that again does not utilize sound waves as part of its methodology. Thus, sonophoresis clearly stands out as the technology designed specifically for medication delivery using high-frequency sound waves.
