Naltrexone Addiction

Naltrexone was first synthesized in 1963 by scientists at Endo Laboratories in New York. The drug worked better than previously discovered opioid antagonists and subsequently chosen for further testing and trials due to the great promise it showed. Clinical trials for opioid dependence began in 1973, culminating in FDA approval for the oral treatment of opioid dependence in 1984 as the drug Trexan, and for the oral treatment of alcohol dependence in 1995 as Revia. A new version that could be administered via intramuscular injection was approved by the FDA under the brand name Vivitrol for alcohol dependence in 2006 and opioid dependence in 2010.
