what is naltrexone and vivitrol
Vivitrol is an extended-release, injectable form of naltrexone. It is a non-addictive opiate antagonist that has helped many individuals remain drug-free during their initial recovery period. It has been used to treat both alcohol and opioid drug dependence.
Naltrexone is a medication that stops the activity of opioids. It is used primarily in the management of alcohol dependence and opioid dependence. The closely related medication, methylnaltrexone, is used to treat opioid-induced constipation but does not treat addiction as it does not cross the blood brain barrier.
