Abstract

Consensus on the optimal dosing of methadone in the treatment of opioid dependence has not yet been achieved, with some programs committed to low dose regimens. This paper presents outcome results for 95 opioid abusers who remained in treatment through a stable dosing period in a double-blind fixed dose clinical trial comparing the relative efficacies of 50 (n = 44) and 20 mg (n = 34) of methadone to methadone-free treatment (n = 17). All patients showed improvements over time on measures of psychosocial functioning and psychological symptoms, emphasizing the important role of non-pharmacologic factors in methadone treatment. Furthermore, orderly dose effect relationships were seen, with patients receiving 50 mg of methadone having significantly lower rates of opioid positive urines (36% vs. 60–73%), and self-reporting a lower frequency of heroin use (3 days vs. 11–12 days per month). These results illustrate the dose-related efficacy of methadone in decreasing illicit opioid use and improving drug-related behavior.

      However, 50 mg methadone was significantly more effective than placebo (MD −2.50 days; CI −7.63, −2.63). Comparing the number of crimes committed, both 20 mg (MD 4.0 fewer crimes) and 50 mg (MD 9.23 fewer crimes) methadone were significantly more effective than the placebo (Strain et al., 1993). Another RCT that randomized 111 offenders with OUD to receive oral naltrexone with standard psychological treatment or standard psychological treatment alone (control) reported no significant difference between groups in the average number of charges (MD-0.30 fewer charges) or convictions per month (MD 0.00 fewer charges; SD not reported; Coviello et al., 2010).

      The average methadone dose in community clinics has increased over the past few decades, with the proportion of patients receiving doses <80 mg decreasing from 94% in 1988 to 56% in 2005 (Maddux et al., 1991; D’Aunno and Vaughn, 1992; D’Aunno et al., 1999; D’Aunno and Pollack, 2002; Pollack and D’Aunno, 2008), and prior outside approval of doses over 100 mg/day is no longer required (Rettig and Yarmolinsky, 1995). The trend toward higher doses has been supported by clinical trials and by retrospective analyses of outcome in clinical populations (Caplehorn and Bell, 1991; Strain et al., 1993; Maremmani et al., 1994; Hartel et al., 1995; Ling et al., 1996; Schottenfeld et al., 1997; Strain et al., 1999; Farré et al., 2002). A Cochrane review of randomized trials found that higher doses of methadone (60–100 mg/day) were more effective than lower doses (1–39 mg/day) in reducing heroin use (Faggiano et al., 2003).
