Eli Lilly developed the diabetes medicine Mounjaro and obesity treatment Zepbound. Eli Lilly and Company is an American pharmaceutical corporation headquartered in Indianapolis, Indiana.
The company was founded in 1876 by Colonel Eli Lilly, a pharmaceutical chemist and Union army veteran. It began with a focus on producing medicines with consistent quality and later became a major international drug manufacturer.
Mounjaro is the brand name for tirzepatide when prescribed for type 2 diabetes. The same active ingredient is marketed as Zepbound in the United States for chronic weight management. Tirzepatide acts on GIP and GLP-1 hormone pathways.
These products are not insulin, although both diabetes and weight-management treatments are often discussed alongside insulin medicines. Their rapid commercial growth made Eli Lilly a central company in pharmaceutical market-cap rankings.
