Eli Lilly is the pharmaceutical company among the world's largest by market cap that developed the diabetes drug Mounjaro.
Mounjaro is the brand name for tirzepatide, a prescription medicine approved in the United States for adults with type 2 diabetes alongside diet and exercise. Eli Lilly developed and markets the drug.
Tirzepatide acts on GIP and GLP-1 hormone pathways. Its effects include helping regulate blood sugar and reducing appetite. The medicine is administered as a once-weekly injection under medical supervision.
Mounjaro is sometimes confused with Zepbound, which contains the same active ingredient, tirzepatide, but is marketed in the United States for chronic weight management in eligible adults. Novo Nordisk is another major diabetes-drug company, but its best-known products include semaglutide medicines such as Ozempic and Wegovy.
