Andrx Granted Summary Judgment for Generic Toprol-XL

January 18, 2006

Andrx Corporation (Nasdaq: ADRX) (“Andrx” or the “Company”) announced today that the U.S. District Court for the Eastern District of Missouri granted motions for summary judgment filed by Andrx and two other pharmaceutical companies with respect to each company’s abbreviated new drug applications (ANDA) for the generic version of Toprol-XL(R) (metoprolol succinate extended-release tablets). The District Court held that the patents asserted by AstraZeneca AB, Aktiebolaget Hassle and AstraZeneca LP (collectively “Astra”), are both invalid due to double patenting and are unenforceable due to inequitable conduct.

The approval and launch of Andrx’s ANDAs for the 25mg, 50mg, 100mg and 200mg strengths of its metoprolol succinate extended-release tablets are subject to, among other things, the Food and Drug Administration’s (FDA) removal of Andrx’s Official Action Indicated (OAI) status, satisfying all other FDA approval requirements, successful validation and potential future legal proceedings by Astra.

Andrx believes it may be entitled to 180 days of market exclusivity on the 50mg strength of generic Toprol-XL, which had U.S. sales of approximately $500 million for the trailing 12 months ended September 2005, based on IMS data.
