“The guidance we’re finalizing today is one of the many steps we’re taking to help advance the development of new treatments for opioid use disorder, and promote novel formulations or delivery mechanisms of existing drugs to better tailor available medicines to individuals’ needs,” Gottlieb said. “Our goal is to advance the development of new and better ways of treating opioid use disorder to help more Americans access successful treatments.”

There are currently only three drugs approved by the FDA for medication-assisted treatment (MAT) – buprenorphine, methadone and naltrexone. Physicians wishing to prescribe buprenorphine to patients must have a special certification from the DEA and are limited in the number of patients they can treat.

Buprenorphine is an opioid that is also used to treat pain. When combined with naloxone, buprenorphine reduces cravings for opioids and lowers the risk of abuse.

Some addicts have discovered that buprenorphine can also be used to get high or to ease their withdrawal pain from heroin and other opioids. Buprenorphine is such a popular street drug that the National Forensic Laboratory Information System ranked buprenorphine as the third most diverted opioid medication in the U.S. in 2014.
