Humulin

Humulin is the brand name for a group of biosynthetic human insulin products, developed by Arthur Riggs, working with Genentech in 1978 (Generic names regular insulin, insulin isophane and the Lente series consisting of Lente (known generically as insulin zinc suspension) is actually a mixture of Ultralente and Semilente) and later acquired by Eli Lilly and Company, the company who arguably facilitated the product's approval with the U.S. Food and Drug Administration. The Lente series was discontinued by Lilly in 2005. Prior to the development of synthesized human insulin, patients were dependent on animal insulin which was more costly, less accessible, and caused infections in some patients.
