Eli Lilly makes the diabetes drug Mounjaro and the obesity drug Zepbound.
Both medicines contain tirzepatide, a prescription compound that activates GIP and GLP-1 receptors. Mounjaro was approved for type 2 diabetes, while Zepbound was approved for chronic weight management in adults with obesity or overweight plus a related condition.
Eli Lilly is an American pharmaceutical company founded in Indianapolis in 1876 by Colonel Eli Lilly. The company became one of the world’s most valuable publicly traded drugmakers as demand grew for its diabetes and obesity treatments.
A common mix-up is confusing the brand names with the compound: tirzepatide is the active ingredient, Mounjaro is the diabetes brand, and Zepbound is the weight-management brand. Novo Nordisk’s Ozempic and Wegovy contain semaglutide instead.
