US scientists have developed an oral insulin capsule for daily use in patients with type 2 diabetes

Recently, American researchers developed an oral insulin capsule, which can transport insulin to the small intestine wall for absorption According to research published in the British journal Nature Medicine, the capsule has a micro needle inside and a polymer material outside, which can withstand the acidity of gastric juice When the acidity in the small intestine is reduced, the capsule will open and spring open three folded forearms, each of which is equipped with a 1 mm long needle The needle contains insulin The elasticity just makes the needle penetrate into the surface of the small intestine and release the drug (http:// Experiments with pigs showed that the capsules could carry the same amount of insulin as the subcutaneous injection In addition, in order to reduce the risk of the capsule blocking the intestinal tract, the needle will dissolve in a few hours after it enters the intestinal wall, and the folding forearm will be disconnected The researchers said the new method could also be used for other protein drugs such as hormones, enzymes, antibodies or RNA drugs.
