Like Ozempic and Wegovy, Eli Lilly's tirzepatide is a weekly injection that changes the way patients eat and leads to decreased appetite by mimicking certain hormones in the gut. But Wegovy only mimics one hunger-regulating hormone called GLP-1, while tirzepatide mimics GLP-1 and another hormone called GIP
Pfizer's weight-loss drug Known as danuglipron, the diabetes and obesity treatment is in a class of drugs called GLP-1 agonists and mimics a hormone the body releases when a person eats food.
