In our article on abuse-deterrent opioids (Med Lett Drugs Ther 2017; 59:95), the information on Targiniq ER in Table 1 is incorrect. The drug, which is not available in the US, is a combination of oxycodone ER and naloxone, not naltrexone, and naloxone is dispersed throughout the tablet, not sequestered. Targiniq ER will be deleted from the table in the article as it appears on our website.
