Naltrexone, an opioid antagonist, has been utilized for treating addiction to both drugs and alcohol. VIVITROL, a medication containing naltrexone, is approved for patients with alcohol dependence who can abstain from alcohol before medication initiation. At the initial administration of VIVITROL, patients must not be actively drinking. Following opioid detoxification, VIVITROL can also be utilized to prevent relapse to opioid dependence. It is vital to keep in mind that VIVITROL should be incorporated into a comprehensive management program that includes psychosocial support. Naltrexone works by blocking opioid receptors, specifically the mu/kappa/delta receptors, thus preventing the effects of opioids. Unlike buprenorphine and methadone that activate opioid receptors to suppress cravings, naltrexone binds and blocks opioid receptors, reducing opioid cravings. Moreover, it does not cause withdrawal symptoms upon discontinuation and does not possess abuse and diversion potential.
