Mallinckrodt receives FDA approval for generic Duragesic

ST. LOUIS — The Food and Drug Administration has approved a painkiller delivered through a skin patch made by Mallinckrodt, the generic drug maker said Friday.

Mallinckrodt, part of Covidien, said the FDA approved its fentanyl transdermal system patch.

The patch is a generic version of Johnson & Johnson’s Duragesic. The drug, an opioid and Class II controlled substance, is used for managing persistent, moderate-to-severe pain that requires continuous opioid administration.
