About Opioid Drugs
Opioids are a class of drugs that include the illegal drug heroin, synthetic opioids such as fentanyl, and pain relievers available legally by prescription, such as oxycodone (OxyContin), hydrocodone (Vicodin), codeine, morphine, and many others.
All opioids are chemically related and interact with opioid receptors on nerve cells in the body and brain. Opioid pain relievers are generally safe when taken for a short time and as prescribed by a doctor, but because they produce euphoria in addition to pain relief, they can be misused (taken in a different way or in a larger quantity than prescribed, or taken without a doctor’s prescription). Regular use—even as prescribed by a doctor—can lead to dependence and, when misused, opioid pain relievers can lead to addiction, overdose incidents, and deaths.

An opioid overdose can be reversed with the drug naloxone when given right away. Improvements have been seen in some regions of the country in the form of decreasing availability of prescription opioid pain relievers and decreasing misuse among the nation’s teens. However, from 2007 until 2011, overdose deaths involving heroin increased dramatically. Fortunately, effective medications exist to treat opioid use disorders, including methadone, buprenorphine, and naltrexone.
A NIDA study found that once treatment is initiated, both a buprenorphine/naloxone combination and an extended release naltrexone formulation are similarly effective in treating opioid addiction. However, naltrexone requires full detoxification, so initiating treatment among active users was more difficult. These medications help many people recover from opioid addiction.
