Andrx Corporation develops and commercializes: bioequivalent versions of controlled-release brand name pharmaceuticals, using its proprietary drug delivery technologies; bioequivalent versions of specialty, niche and immediate-release pharmaceutical products, including oral contraceptives; and brand name or proprietary controlled-release formulations of existing immediate-release or controlled-release drugs where it believes the application of Andrx's drug delivery technologies may improve the efficacy or other characteristics of those products. Andrx also has distribution operations, which purchase primarily generic pharmaceuticals manufactured by third parties and sell them primarily to independent pharmacies, pharmacy chains, pharmacy buying groups and, to a lesser extent, physicians' offices. Andrx intends to grow its business through internal research and development, brand sales and marketing efforts, strategic alliances and selected-acquisitions and dispositions.
