Automated drug delivery.(Pharmaceutical)(Brief Article)

R & D, October, 2004

Traditional methods of drug delivery require a caretaker or the patient themselves to administer the drugs when needed. All that can change with the advent of automated drug delivery systems. Researchers from the Georgia Institute of Technology, Atlanta, have developed micro-thin implantable films that hold and then release medication according to changes in temperature. A decade's worth of work in targeted drug delivery methods have shown the researchers that films assembled from microparticles allow more control over drug release than films made previously in monolithic form.

"We loaded insulin in layers of microgel films in the lab and released bursts of insulin by applying heat to the films," says Andrew Lyon, associate professor at Georgia Tech's School of...
