Craving in heroin addicts maintained on the opiate antagonist naltrexone

Abstract

The level of heroin craving was monitored in patiens receiving naltrexone on a regular basis. Meetings and interviews conducted twice weekly attested to a pattern of craving reduction in most but not all the addicts. It was also found that it usually took 3 to 5 weeks for this effect to occur. The possible relationship between drug craving and participation in the naltrexone program is discussed.
