CNN -- Out with the old, and in with the new? Daily Insulin shots for Diabetics could soon be replaced with an oral alternative.
There have been ongoing efforts to develop a more simple method to administer Insulin, for the more than 400 million people living with Diabetes.
About 40 percent who are Type 1 or Type 2, use Insulin, most commonly with a syringe, pen injection or a pump. Scientists have been working on a way to make the injections a thing of the past by developing an oral alternative.
A bioengineering professor at Harvard believes a pill form would make it easier for Diabetics. However, the biggest challenge would be keeping the Insulin from deteriorating as it makes it way through the digestive system.
A new study found that a liquid form of Insulin inside a capsule, not only lowered the blood glucose levels on test rats, but the levels dropped nearly 40 percent in just two hours. An encouraging sign, but there is still more clinical trials to be done before testing on humans.
Some experts hope that will be possible within the next 3 to 5 years.
In addition to further testing, more research is also needed to address any potential risks that may come with Insulin capsules.
