Anchor Lede: Your future flu shot could be as easy as swallowing a pill. One concept in development has a Halloween-like twist – the needles come out inside your body.
Randy Atkins: The goal is to engineer a pill for drugs that currently require an injection. Giovanni Traverso, a gastroenterologist at Massachusetts General Hospital and an MIT researcher, has created a device with an easily-swallowed smooth outer coating.
Giovanni Traverso: But then, once it reaches the G-I tract, that coating would dissolve revealing the needles.
Randy Atkins: Injections would happen as the digestive system squeezes and pushes the pill along…or through a biodegradable needle that breaks off like a bee’s stinger. In animal tests with insulin…
Giovanni Traverso: …we could deliver it and actually it seemed to be delivered more effectively, at least in this very preliminary work.
Randy Atkins: The needles are tiny but, even so, Traverso points out that the GI tract doesn’t have much sensation…so you, literally, wouldn’t feel a thing. With the National Academy of Engineering, Randy Atkins, WTOP News.
