Eli Lilly developed the blockbuster diabetes drug Mounjaro and obesity drug Zepbound.
Both medicines contain tirzepatide, a drug that activates receptors for two hormones involved in blood-sugar regulation and appetite. Mounjaro is marketed for type 2 diabetes, while Zepbound is marketed for chronic weight management in eligible patients. Their success made Eli Lilly one of the world's most valuable pharmaceutical companies.
Eli Lilly and Company was founded in Indianapolis in 1876 by Colonel Eli Lilly, a pharmaceutical chemist and Union army veteran. The company became known for insulin, antibiotics, psychiatric medicines, and other prescription treatments.
Mounjaro and Zepbound are brand names, not separate active compounds. The active ingredient is tirzepatide. They are also distinct from semaglutide products such as Ozempic and Wegovy, which are made by Novo Nordisk.
