Amerigen Pharmaceuticals

Amerigen Pharmaceuticals was a privately held generic pharmaceutical company focused on the development, manufacture, and commercialization of multisource prescription medicines, primarily for the U.S. market, with additional operating links to China. The company operated through entities including Amerigen Pharmaceuticals Limited and Amerigen Pharmaceuticals, Inc., and pursued Abbreviated New Drug Applications for generic versions of marketed products. Publicly referenced products and approvals included generic mixed amphetamine salts extended-release capsules and penicillamine capsules. Available business-directory sources indicate the company was based in Lyndhurst, New Jersey and employed roughly 51-100 people before later being marked as closed by company-data platforms. It was not a biotechnology innovator with a novel clinical pipeline; rather, it was a commercial-stage generic drug developer and marketer.
