New drug delivery system uses magnetism
There are many medical conditions that involve medication with intermittent doses on an as-needed basis, and often, that medication cannot be taken orally.
Scientists have long struggled with how best to deliver medication under these circumstances, where the delivery system might meet three key needs: intermittent dosing, with extreme precision, over the long term.
Research led by Daniel Kohane at Children's Hospital Boston may have hit on an effective new approach: a tiny, implantable device that releases the medication through a membrane whose porousness responds to the switching on or off of a magnetic field.
The membrane is embedded … Read more
