Getting (drugs) under your skin
Date:9/14/2012

to the researchers. It has already been shown that injections into the skin can induce the type of immune response necessary for immunization, so vaccination by skin patch could be a needle-free, pain-free way to deliver vaccines. This would be especially beneficial in developing countries, since the training required to administer such patches would be less intensive than that needed to give injections. The Blankschtein and Langer groups are now pursuing this line of research.

They are also working on a prototype for a handheld ultrasound device, and on ways to boost skin permeability even more. Safety tests in animals would be needed before human tests can begin. The U.S. Food and Drug Administration has previously approved single-frequency ultrasound transdermal systems based on Langer and Blankschtein's work, so the researchers are hopeful that the improved system will also pass the safety tests.
