Eli Lilly is the pharmaceutical company that developed the diabetes and obesity drug Mounjaro and became one of the richest companies by market cap.
Eli Lilly and Company was founded in Indianapolis in 1876 by Colonel Eli Lilly, a pharmaceutical chemist and Union veteran. The company became known for standardized medicines and later developed major products in diabetes, oncology, immunology, and neuroscience.
Mounjaro is the brand name for tirzepatide when prescribed for type 2 diabetes in the United States. Tirzepatide acts on GIP and GLP-1 pathways, while the company markets it for chronic weight management under the name Zepbound. Eli Lilly is often confused with Novo Nordisk, another leading diabetes-drug company that makes semaglutide products.
