For example, the FDA recently approved lofexidine, a non-opioid medicine deed to reduce opioid withdrawal symptoms. Methadone and buprenorphine are other medications approved for this purpose.
Methadone is a synthetic opioid agonist that eliminates withdrawal symptoms and relieves drug cravings by acting on opioid receptors in the brain—the same receptors that other opioids such as heroin, morphine, and opioid Does methadone treatment work medications activate. Although it occupies and activates these opioid receptors, it does so more slowly than other opioids and, in an opioid-dependent person, treatment doses do not produce euphoria. It has been used successfully for more than 40 years to treat opioid use disorder and must be dispensed through specialized opioid treatment programs.
Buprenorphine is a partial opioid agonistmeaning that it binds to those same opioid receptors but activates them less strongly than full agonists do. Like methadone, it can reduce cravings and withdrawal symptoms in a person with an opioid use disorder without producing euphoria, and patients tend to tolerate it well. Research has found buprenorphine to be similarly effective as methadone for treating opioid use disorders, as long as it is given at a sufficient dose and for sufficient duration.

These formulations are available to patients stabilized on buprenorphine and will eliminate the treatment barrier of daily dosing for these patients.

Instead of controlling withdrawal and cravings, it treats opioid use disorder by preventing any opioid drug from producing rewarding effects such as euphoria. Its use for ongoing opioid use disorder treatment has been somewhat limited because of poor adherence and tolerability by patients.
