bonustime MIT develops capsule as needle-free alternative to medications
Updated:2024-11-22 03:23 Views:87
MIT and Novo Nordisk researchers have developed a capsule that lets patients receive medications without injections.
MIT News says it can deliver insulin, antibodies and vaccines.
Also, it can become a more sustainable alternative because it won’t require disposable needles.

Soon, your next shot might be a smooth, prick-free experience!

— Massachusetts Institute of Technology (MIT) (@MIT) January 2, 2024Giovanni Traverso, director of the Laboratory for Translational Engineering at MIT, explained how he and his team created the capsule.

A carbohydrate trigger keeps the gas or spring in a compressed state. Then, it dissolves once it enters the stomach’s acidic and humid environment.

The researchers also designed different versions for specific parts of the digestive tract.
The first had a flat bottom and a high dome, allowing it to sit on the stomach lining.
On the other hand, the second has a tube-like structure that lets it align itself within the esophagus or small intestine.
The first can carry 80 microliters of medication, and the second can hold 200 microliters.
Moreover, they can pass through and exit the digestive tract.
“This technology is a significant leap forward in oral drug delivery of macromolecule drugs like insulin and GLP-1 agonists,” said Omid Veiseh, a professor of bioengineering at Rice University.
“While many approaches for oral drug delivery have been attempted in the past, they tend to be poorly efficient in achieving high bioavailability.”
“This is an exciting approach which could be impactful for many biologics which are currently administered through injections or intravascular infusions.”
