Scientists in the US have designed an oral drug capsule that can carry insulin and protect it from the harsh environment in the digestive tracts.
The study published in this week's Nature Medicine has shown that the capsule containing proteins that cannot be taken orally reaches the small intestine before breaking down to release dissolvable tiny needles, the Xinhua news agency reported.
Those needles then attach to the intestinal wall and release drug for fast uptake into the bloodstream, according to the study.
