About one in four older adults suffers from chronic pain. Many of those people take medication, usually as pills. But this is not an ideal way of treating pain: Patients must take medicine frequently, and can suffer side effects, since the contents of pills spread through the bloodstream to the whole body. Now researchers at MIT have refined a technique that could enable pain medication and other drugs to be released directly to specific parts of the body — and in steady doses over a period of up to 14 months. The method uses biodegradable, nanoscale “thin films” laden with drug molecules that are absorbed into the body in an incremental process. Professor Paula Hammond and Brian Hsu PdD ’14 have been instrumental in the development.” Continue reading at MIT News.
