Breakthrough set to help cut diabetics' injections.
Researchers at a Sunderland University developed a simple, once-a-day nasal gel to help with the chronic condition.
Dr Hamde Nazar, a senior lecturer in pharmacy practice, said the project could put an end to daily injections of insulin for people with Type 1 diabetes and some Type 2 diabetics.
Results from tests showed that gel loaded with insulin reduces the blood glucose levels over 24 hours in a diabetic model when administered through the nose and into the bloodstream.
When insulin was taken via an injection, it took just nine hours to return to their normal levels. Dr Nazar said: "This process could potentially be beneficial because it would reduce the number of injections patients would have to administer.
"Some people have to take up to five injections per day. This could replace some of those injections."
The research was published yesterday to coincide with World Diabetes Day.
The event is held annually on November 14, the birthday of Frederick Banting, the man who co-discovered insulin.
It is thought around 300,000 people in the UK suffer from Type 1 diabetes which destroys insulin-making cells in the pancreas. Globally, an estimated 346 million people have Type 2 diabetes. Sufferers of the condition must inject themselves a number of times each day to prevent blood glucose levels going too high.
The research led by Dr Nazar has been published in the Royal Society of Chemistry journal, Biomaterials Science.
