This drug, not bigger than a blueberry, contains a small needle made of compressed insulin, which is injected as it reaches the stomach. The shaft of the needle, which does not enter the stomach wall, is made from another biodegradable material. When the capsule is swallowed, water in the stomach dissolves the sugar disk, releasing the spring and injecting the needle into the stomach wall. The stomach wall has no pain receptors, so the researchers believe that patients would not be able to feel the injection. In tests in pigs, the researchers showed that they could successfully deliver up to 300 micrograms of insulin.
