The precedent of Mediator, as well as the possible risk of relapse after stopping treatment, are they not obstacles to prescribing? How to reassure doctors?
Research on GLP-1 analogues dates back to the 1980s, so these molecules and their effects have been known for a long time. We marketed our first antidiabetic drug in this therapeutic class in 2008. Today, 42 million patients worldwide have benefited from our treatments, including 40.6 million for diabetes and nearly 1.5 million for obesity. we have been dealing for four years in USA. This decline allows us to see that the beneficial effects on
