LAST OF THE NEEDLES?
A medical jelly has been developed that could mean the end of painful injections for diabetics.
The gel, which is designed to be swallowed, offers a way to deliver a range of treatments that at present can only be injected.
They include insulin, which about 575,000 diabetics in the UK currently have to administer themselves daily.
The gel could also be used to deliver drugs for inflammatory bowel disease, bowel cancer, and some infections, it is claimed.
Scientists in India have tested the system successfully in the laboratory and now want to move on to human trials.
Many medicines cannot be taken as pills or capsules because they are destroyed by powerful stomach acids and enzymes before being absorbed into the body.
Instead they have to be injected, either under the skin, or into a muscle or vein.
The hydrogel developed at the Government Model Science College in Jabalpur passes through the stomach largely unscathed and protecting the drug trapped within it.
When it reaches the large intestine, more alkaline conditions there cause the gel to swell and release its medicine.
