Long-acting depot formulations of naltrexone for heroin dependence: a review

Curr Opin Psychiatry. 2010 May;23(3):210-4. doi: 10.1097/YCO.0b013e3283386578.

Abstract

Purpose of review: The major problem with the oral formulation of naltrexone for heroin dependence is poor compliance (adherence). Long-acting sustained release formulations of naltrexone (implantable and injectable) might help to improve compliance and, thus, increase the efficacy of abstinence-oriented treatment of heroin dependence with naltrexone.

Recent findings: There have been several implantable and injectable formulations of naltrexone developed within the last decade. It was demonstrated that some of them are effective and relatively well tolerated medications for relapse prevention in heroin addicts. However, advantages and disadvantages of these new medications have never been systematically analyzed.

Summary: Long-acting sustained release formulations of naltrexone are well tolerated and more effective for relapse prevention in heroin addicts than the oral ones.
