Hmm...I have to say, I'm not all that excited by it. By the details in the article, it looks like, same as injections, it doesn't really change what happens to the insulin once it gets into the body. You take a specific dose, it gets to your intestines and gets released all at once, works for 5 hours and is done.
Of course, that would be great news for people with a fear of needles. It may also be interesting for folks with gastroparesis, since it guarantees the insulin won't reach the bloodstream until the food does! (Although for the rest of us, that may be a negative point, if you have a sluggish digestion or are eating a large or high-fat meal!)
But by and large I really wish researchers would stop focusing on "fewer injections", because that REALLY isn't the biggest hurdle to insulin use. It only looks like it from the outside - so to me, unless researchers can point to a benefit of non-injected insulin beyond just "fewer injections," projects like this seem like the mark of people researching diabetes who don't know much about actually living with diabetes or what actual diabetics would want to improve their lives. Injected insulin works just fine, and by trying to get away from injections I'm always worried that I would also be getting away from having precision control over just how much insulin is in my body.
Now, an insulin with an adaptive action profile, THAT would be really exciting!
