  • Ultrasound enhancement of transdermal drug delivery
    Patent number: 4767402
    Abstract: The present invention is a method using ultrasound to enhance permeation of molecules through the skin and into the blood stream, at a controlled rate. Depending on the drug being infused through the skin, the rate of permeation is increased as well as the efficiency of transfer.
