Abstract

This systematic review summarises evidence of the effectiveness of naltrexone (NTX) and the added value of psychosocial treatment in the maintenance treatment of opioid and alcohol dependence.

Studies were selected through a literature search conducted in March 2004. Seven opioid and seventeen alcohol studies were identified. When possible, meta-(regression) analyses were performed. There is lack of evidence about the effectiveness of NTX in the maintenance treatment of opioid dependence. There is evidence for the effectiveness and applicability of NTX in the management of alcohol dependence. The opioid studies combined NTX with a variety of psychosocial interventions, which plagued the evaluation of their value. Concomitant psychosocial interventions used in the alcohol studies were mainly cognitive behavioural, which seems to be more effective than NTX combined with supportive therapy. Available data do not allow firm conclusions regarding the added effect of psychosocial interventions. However, the data suggest that a combination of naltrexone with cognitive behavioural relapse prevention therapy is beneficial in alcohol dependent patients.

Introduction

Naltrexone (NTX), an opioid antagonist, blocks intrinsic properties of psychoactive substances that act on the μ, κ, and δ opioid receptor sites by competitive occupation. It is ascertained that alcohol acts on the opioid receptor sites. By blocking these sites, NTX prevents the reinforcing effects of alcohol consumption (O'Brien et al., 1996). The metabolic pattern of NTX predominantly involves the reduction of NTX into 6-β-hydroxy naltrexone (6-β-naltrexol; Wall et al., 1981). The long acting properties of NTX are mainly due to this metabolite, which has an elimination half-life (T1/2) of approximately 13 h compared to the parent drug with a T1/2 value of 4 h. The dose-related antagonism on both subjective and objective responses has been subject to some research, although these findings are based on small samples (Resnick et al., 1974, Verebey, 1981). NTX and 6-β-naltrexol are dose proportional (linear increase) in terms of AUC and Cmax over the range of 50 to 200 mg. A bio-equivalence was demonstrated after 100-mg single doses (Meyer et al., 1984). Despite the excellent pharmacological (blocking) properties, in practice NTX treatment is often hampered by dropout, non-compliance and consequently relapses into opioid or alcohol abuse (Rothenberg et al., 2002, Tucker et al., 2004).

However, evidence is scant regarding the question whether and which type of psychosocial intervention should be combined with NTX treatment in order to optimise its effectiveness.

First and foremost, the current study was conducted to unfold and update the effectiveness of NTX. To summarise the available (recent) evidence on the effectiveness of NTX, in the maintenance treatment of alcohol and opioid dependence, a systematic (meta-analytic) review was conducted with the following aims:

  • 1.

    to study the effects of NTX compared to placebo in the maintenance treatment of opioid and alcohol dependence;

  • 2.

    to study whether combining NTX with psychosocial treatment is more effective than treatment with NTX alone.

Criteria for considering studies for this review

Randomised (placebo) controlled trials (RCTs) and controlled clinical trials (CCTs) with NTX maintenance treatment were included. When group allocation in a trial was determined randomly, the study could be labelled as an RCT. If the randomisation procedure was unclear, but considered as randomised (e.g. double-blind study), the trial was assumed to be a CCT.

RCTs and CCTs had to include participants with alcohol or opiate abuse or dependence (DSM-III-R or DSM-IV) between 18 and 75 years of age.

Study selection: NTX in opioid studies

After consulting Pubmed, EMBASE, PsychINFO and CCTR 119, 275, 149 and 65 publications, including duplicates, were identified respectively. Only seven placebo-controlled trials on maintenance treatment of opioid dependence met the selection criteria and were included in the review (Brahen et al., 1977, Guo et al., 2001, Hollister, 1978, Lerner et al., 1992, Mello et al., 1981, San et al., 1991, Shufman et al., 1994).

Study selection: NTX in alcohol studies

The search via Pubmed, EMBASE, PsychINFO and CCTR yielded 136, 461, 101 and 165

Discussion

We conducted a review on the effectiveness of NTX in the maintenance treatment of opioid and alcohol dependence. Where possible, studies were statistically pooled using the random effects model. This model takes into account the within-study sampling error and between-studies variation.

      With regards to the community-reinforcement approach, dual treatment with disulfiram significantly improved pharmacotherapy compliance, resulting in near-total sobriety in a study in outpatients at a rural community alcoholism treatment clinic (Azrin et al., 1982). For nicotine and heroin dependence, treatment with both the community-reinforcement approach and naltrexone increased rates of abstinence (Roozen et al., 2003; Roozen et al., 2006). However, there are also several studies that did not see enhanced efficacy with combinatory pharmacotherapy and psychosocial treatment in cocaine (Mancino et al., 2014; Mooney et al., 2009; Walsh et al., 2013; Wardle et al., 2017), cocaine and opioid (Umbricht et al., 2014), cocaine and alcohol (Schmitz et al., 2009), or methamphetamine dependence (Heinzerling et al., 2012; Shoptaw et al., 2008).

      Active drug use was defined as a positive urine toxicology screen for either opioids or cocaine on the first interview post-release. XR-NTX treatment duration was stratified based on receiving at least 12 weeks of treatment (4 injections or more), based on a systematic review (Bouza et al., 2004) and confirmatory meta-analysis (Roozen et al., 2006) showing that this treatment was associated with better alcohol treatment outcomes. Though the primary outcome for the parent study involved the proportion achieving HIV-1 RNA viral suppression, the primary outcome for this analysis was related to alcohol consumption, which was assessed both before incarceration and after release using the following outcomes: 1) time to first heavy drinking day post-incarceration, 2) total number of drinks per drinking day; 3) the percent of heavy drinking days; 4) comparison of pre- and post-incarceration change in average drinks per drinking day; and 5) the total number of drinking days.
