PURDUE LAUNCHES OXYCONTIN AUTHORIZED GENERIC WITH IVAX
Purdue Pharma has launched an authorized generic of its blockbuster painkiller OxyContin -- a move that comes shortly after Endo Pharmaceuticals became the first firm to launch a generic version of the drug in 10-, 20- and 40-mg and dosage strengths.
Purdue launched its authorized generic in partnership with Ivax, which recently said it had begun selling generic OxyContin (oxycodone HCl) in 10-, 20-, 40- and 80-mg dosage strengths.
Endo moved forward with its generic product June 7 after a three-judge panel of the U.S. Court of Appeals for the Federal Circuit, affirmed a January 2004 decision by the U.S. District Court for the Southern District of New York, which invalidated three of Purdue's patents.
Teva Pharmaceutical was the first generic firm in the OxyContin market, launching an 80-mg tablet product in March 2004.
