Endo Pharmaceuticals Inc

Endo Pharmaceuticals Inc. is a diversified pharmaceutical company with a history dating back to 1920 when it was founded as Intravenous Products of America, Inc. by the Ushkow family. The modern iteration of the company was formed in 1997 through a management buyout from DuPont Merck, led by Carol Ammon, Louis Vollmer, and Mariann MacDonald. This transaction, financed by Kelso & Co., included several pain management drugs, such as Percocet.

The company operates through four main segments: Branded Pharmaceuticals, Sterile Injectables, Generic Pharmaceuticals, and International Pharmaceuticals. Its business model focuses on developing, manufacturing, and commercializing both branded and generic drugs. Revenue is generated from the sale of these products to a wide range of customers, including primary care physicians, specialists, retail pharmacies, hospitals, and government agencies. A significant portion of its revenue comes from key products like XIAFLEX®, used for treating Dupuytren's contracture and Peyronie's disease, and VASOSTRICT®, an injectable used for hypotension. For the fiscal year 2024, XIAFLEX® revenues surpassed $500 million for the first time.

Endo's product portfolio is extensive, covering therapeutic areas such as urology, orthopedics, endocrinology, and pain management. The Branded Pharmaceuticals segment focuses on specialty products for specialists like urologists and orthopedic surgeons. The Sterile Injectables division partners with hospitals and healthcare systems, providing products like ready-to-use injectables. The Generics segment provides high-quality, lower-cost alternatives to branded drugs. The company has engaged in numerous strategic acquisitions to expand its portfolio, including Qualitest Pharmaceuticals in 2010, American Medical Systems in 2011, and Par Pharmaceutical in 2015.

In August 2022, facing significant litigation primarily related to its opioid products, Endo International plc initiated Chapter 11 bankruptcy proceedings. As part of its restructuring, the company reached settlements to resolve these legal challenges. In March 2024, the court confirmed Endo's plan of reorganization, allowing it to emerge from bankruptcy with a substantially reduced debt load. Substantially all of the company's assets were sold to a new entity, Endo, Inc., which completed the acquisition in April 2024. As of March 2025, Endo has announced a definitive agreement to combine with Mallinckrodt plc.
