Robert Doyle, a chemist from Syracuse University (New York), has invented chewing gum with insulin.
This invention was applied for to the WIPO.

The number of diabetes diseased in the world is such that the specialists speak of the epidemic. All these diseased get insulin by means of injections. There’s existed no other effective ways to deliver this kind of hormone of peptide nature to blood flow till this time. Though in 2006 insulin inhaler appeared in the American market, it was taken out from production because of its unprofitability.

Many diabetics would like to get insulin in tablets, though the research work of many years has shown that the digestive system easily destroys this hormone, and the unhurt insulin cells penetrate into blood with much ado.

Fortunately, Robert Doyle has found the way to deliver insulin, which will make the life of diabetes diseased much easier. The scientist noticed that the organism has a specific mechanism of protection and absorption of the molecules of nutrients, which are usually damaged in the digestive tract. E.g. vitamin B12 gets combined with salivary protein haptocorrine in the mouth, due to which it remains whole in the stomach. As soon as haptocorrine gets to the intestine, other chemicals start working; this helps vitamin B12 to penetrate into the blood flow.

Doyle offers to tie insulin molecules with vitamin B12, which will trail the hormone to the circulatory system. The experiment on rats has shown that the scheme works perfectly. The rats got the new medicine in liquid state, but for a man the best way to get the hormone will be to chew the insulin.
