HAYWARD, Calif. — Another generic drug maker is seeking to market its version of a popular opioid painkiller.
Impax said it had filed applications with the Food and Drug Administration seeking approval for a generic version of Purdue Pharma’s Oxycontin (oxycodone) controlled-release tablets in the 10-, 15-, 20-, 30-, 40-, 60- and 80-mg strengths.
Purdue filed suit against Impax on April 8 in the U.S. District Courts for the Southern District of New York, seeking to prevent Impax from marketing its version before the expiration of Purdue's patents.
