Oral insulin for diabetics showing promise

Posted: Updated:

TAIWAN - Oral insulin for diabetics is showing promise, according to researchers at National Tsing Hua University in Taiwan.

The study, published in Biomacromolecules by the American Chemical Society, said scientists have tested an oral form of insulin in rates, but have yet to test it in humans.  The oral form hasn't worked in the past because it gets diluted by the stomach and doesn't reach the bloodstream in its pure form.

But in these new tests, researchers bundled insulin with a chemical made from the shells of shrimp, crabs and lobsters, which were broken into small particles.  They say the solution was able to lower glucose levels in diabetic male rats.
