According to Science Daily, an MIT-led research team developed a drug capsule, that can deliver oral insulin instead of injecting insulin to treat patients with type II diabetes. The capsule is said to be the size of a blueberry, which contains a small needle, made of compressed insulin, which is injected after the capsule reached the stomach. Tested on animals, researchers showed that the pill could deliver enough insulin to lower blood sugar as much as the injections given through skin.
Having been developed before, the pill has been modified to contain one needle, which is made of nearly 100% compressed, freeze dried insulin. The way it works is; when the capsule is swallowed, water in the stomach would dissolve the sugar disk, releasing the spring and injecting the needle into the stomach wall. The stomach wall has no pain receptors, therefore patients would not feel the injection. The needle orients itself, where no matter the position, it will target the stomach wall. Once the top of the needle is injected into the stomach wall, insulin dissolves at a controlled rate and is then released into the bloodstream.
This is a very important topic, many people suffer from diabetes. However type II diabetes is often hereditary and non-preventable, and surviving with injections everyday is tough. With this new insulin pill, we can help many people battle type II diabetes and make it easier to manage. I hope that they will do further research and allow this "pill form" insulin to be promoted for pharmaceutical use.
