HealthDay News — The FDA has approved oxycodone hydrochloride and naloxone hydrochloride extended release (Targiniq ER) as a long-term, around-the-clock treatment for severe pain when other therapies are ineffective or unavailable.

Targiniq ER has properties that are designed to deter abuse of the drug by snorting or injection, the FDA said in a news release.

It contains naloxone, which is designed to block the euphoric effects of oxycodone. The drug can still be abused by taking too many pills, the agency warned, stressing that an overdose could cause death. The drug is not meant for as-needed pain relief repeating its warning of the potential for abuse and addiction.

The agency said it is requiring the manufacturer to conduct additional post-marketing studies to assess the drug’s risks of misuse, addiction, and abuse.
