Pharmaceuticals Grows : 1969

In Depth

Founded in 1920 as an independent, family-run pharmaceuticals business, Endo had achieved success with the anticoagulant drug Coumadin®. During the 1970s, DuPont worked to expand Endo’s line of analgesics and to develop treatments for drug addiction, but Endo proved unable to accommodate the expansion and squabbling among research groups slowed development of new drugs. In anticipation of an effort to acquire new drug companies, Endo was renamed DuPont Pharmaceuticals in 1982. Eight years later, DuPont Pharmaceuticals and drug giant Merck & Company formed a joint venture known as the DuPont Merck Pharmaceuticals Company. Endo re-emerged in 1994 as Endo Laboratories, LLC as the generics division of DuPont Merck. In 1997 three executives from DuPont Merck purchased Endo Laboratories and renamed the company Endo Pharmaceuticals, Incorporated.
