Mylan Comments on Fentanyl OpportunityPITTSBURGH--(BUSINESS WIRE)--Nov. 25, 2003--Yesterday, Mylan Laboratories Inc. (NYSE:MYL) announced that its subsidiary, Mylan Technologies, Inc., received final approval from the U.S. Food and Drug Administration (FDA) for its fentanyl transdermal system, which is bioequivalent to Alza Corporation's Duragesic^®. Final approval was granted by the FDA notwithstanding patent litigation in the U.S. District Court for the District of Vermont and the grant of pediatric exclusivity to Alza for Duragesic. This approval confirmed Mylan's position that neither a 30 month stay, nor pediatric exclusivity, applied to Mylan to receive approval because Alza failed to sue within 45 days after receiving notice of Mylan's Paragraph IV certification. Mylan's final post-trial brief setting forth this position was filed by the close of business on Monday.

Vice Chairman and CEO Robert J. Coury stated, "We have always viewed fentanyl as a substantial opportunity for Mylan, its shareholders and the consumers. We intend to launch the product upon appropriate findings in the litigation but in no event later than when the Alza patent expires on July 23, 2004."

Mylan Laboratories Inc. is a leading pharmaceutical company with four subsidiaries, Mylan Pharmaceuticals Inc., Mylan Technologies Inc., UDL Laboratories Inc. and Bertek Pharmaceuticals Inc., that develop, manufacture and market an extensive line of generic and proprietary products.
