Abstract
Aims: Xtampza® ER (Collegium Pharmaceutical, MA, USA) is an abuse-deterrent formulation (ADF) of oxycodone intended to deter tampering for use by unintended routes of administration. We assessed whether Xtampza ER exposures were less likely to result in severe medical outcomes relative to other opioid analgesic exposures. Materials & methods: Exposures reported to participating poison centersbetween2016 and2021 inclusivethat were followed to a known medical outcome were analyzed. Xtampza ER was compared with other ADF opioids, non-ADF extended-release opioids, single-entity oxycodone immediate-release, unspecified oxycodoneand unspecified morphine. Results & conclusion: No Xtampza ER exposures involved unintended routes of administration. Xtampza ER exposures were less likely to be abuse, misuse or suspected suicidal, and medical outcomes were less severe than comparators.
