PHILADELPHIA, PA – November 16, 2004 – LANNETT ® COMPANY, INC. (AMEX: LCInews), a manufacturer of generic pharmaceuticals, is pleased to announce the launch of three new drug products: Hydromorphone 2 and 4 milligram tablets and a veterinary drug product. Hydromorphone tablets, generic versions of Dilaudid®, marketed by Abbott Laboratories, are narcotic analgesics prescribed for pain. The veterinary drug is the Company’s first product in the field of veterinary medicine—it is used in small dogs and cats. All three products are manufactured by Lannett.

The active pharmaceutical ingredient (API) used in Lannett’s Hydromorphone tablets is supplied by Cody Laboratories (Cody), based in Cody, Wyoming. Lannett and Cody have collaborated on several generic drug projects, including projects in which Cody manufactures the API exclusively for Lannett. Hydromorphone is the first collaborative project between the two companies which has been successfully brought to the commercial market. The other projects are still in development. The current total annual brand retail sales market volume for Dilaudid® 2 and 4 milligram tablets is approximately $10 million. The size of the market for the new veterinary product is unknown as this time.
