Which pharmaceutical company makes the weight-loss drug Zepbound and diabetes drug Mounjaro?

The story behind the answer

Eli Lilly makes the weight-loss drug Zepbound and diabetes drug Mounjaro.

Eli Lilly and Company is an American pharmaceutical corporation founded in Indianapolis in 1876 by Colonel Eli Lilly. The company developed a long-term focus on medicines for diabetes, cancer, immunology, neuroscience, and other conditions.

Zepbound and Mounjaro contain tirzepatide, a medicine that acts on two hormone pathways 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.

These brand names should not be confused with semaglutide products such as Ozempic and Wegovy, which are made by Novo Nordisk. Drug approvals and labels differ by country, so medical use should always be checked against local regulatory information and professional advice.
