Naltrexone is an opioid receptor antagonist used primarily in the management of alcohol dependence and opioid dependence . It is marketed in generic form as its hydrochloride salt , naltrexone hydrochloride , and marketed under the trade names Revia and Depade . In some countries including the United States, an extended-release formulation is marketed under the trade name Vivitrol . It should not be confused with naloxone , which is used in emergency cases of overdose rather than for longer-term dependence control. This is not to say that Naltrexone cannot be used to reverse an overdose from opioids, since being a full antagonist, it will reverse an overdose. However, given that Naltrexone is a longer-acting antagonist, Naloxone would be a more ideal antidote in emergency situations. less
