A drug used to treat Type 2 diabetes and obesity could also slow down the process of ageing, researchers believe. Semaglutide, better known as Ozempic, "has far-reaching benefits beyond what we initially imagined," Prof Harlan Krumholz, from the Yale School of Medicine, said following the publication of several new studies. They found that the drug could be used to treat a wide range of illnesses linked to heart failure, arthritis, Alzheimer's and even cancer. The new data has been published in a number of medical journals, including the Journal of the American College of Cardiology (JACC), which Prof Krumholz edits.
