Mallinckrodt receives FDA approval for Xartemis XR
DUBLIN — Mallinckrodt Plc last week announced that the Food and Drug Administration approved Xartemis XR (oxycodone hydrochloride and acetaminophen) Extended-Release Tablets (CII), for the management of acute pain severe enough that it requires opioid treatment.
The drug also is indicated for patients for whom alternative treatments have shown to be ineffective. Xartemis XR, previously known as MNK-795, is the first and only extended-release oral combination of two clinically proven pain medications — oxycodone and acetaminophen.
