Effectiveness of Buprenorphine Treatment

"A number of clinical trials have established the effectiveness of buprenorphine for the maintenance treatment of opioid addiction. These have included studies that compared buprenorphine to placebo (Johnson et al. 1995; Ling et al. 1998; Fudala et al. 2003), as well as comparisons to methadone (e.g., Johnson et al. 1992; Ling et al. 1996; Pani et al. 2000; Petitjean et al. 2001; Schottenfeld et al. 1997; Strain et al. 1994a, 1994b) and to methadone and levo-alpha-acetyl-methadol (LAAM) (Johnson et al. 2000).

Buprenorphine for Maintenance or Detox

"Buprenorphine can be used for either longterm maintenance or for medically supervised withdrawal (detoxification) from opioids. The preponderance of research evidence and clinical experience, however, indicates that opioid maintenance treatments have a much higher likelihood of long-term success than do any forms of withdrawal treatment. In any event, the immediate goals in starting buprenorphine should be stabilization of the patient and abstinence from illicit opioids, rather than any arbitrary or predetermined schedule of withdrawal from the prescribed medication."

Availability of Treatment for Opioid Dependence and the "Treatment Gap"

"Nationally, in 2012, the rate of opioid abuse or dependence was 891.8 per 100,000 people aged 12 years or older compared with national rates of maximum potential buprenorphine treatment capacity and patients receiving methadone in OTPs of, respectively, 420.3 and 119.9. Among states and the District of Columbia, 96% had opioid abuse or dependence rates higher than their buprenorphine treatment capacity rates; 37% had a gap of at least 5 per 1000 people.

Methadone Treatment Associated with Reductions in Frequency of Opioid Use, Fewer Injections, and Lower Rates of HIV

"In summary, data from studies conducted in Australia, Europe, Asia and the United States have, with few exceptions, found strong associations between participation in methadone treatment and reductions in the frequency of opioid use, fewer injections and injection-related HIV risk behaviors, and lower rates of HIV prevalence and incidence. Few randomized controlled trials have been conducted due to ethical concerns regarding the random assignment of individuals to no treatment or other potentially less effective treatment modalities.

Methadone Mortality and Pain Medicine

Methadone Mortality and Pain Medicine: "Taken together, the data confirm a correlation between increased methadone distribution through pharmacy channels and the rise in methadone-associated mortality. The data, thus, support the hypothesis that the growing use of oral methadone, prescribed and dispensed for the outpatient management of pain, explains the dramatic increases in methadone consumption and the growing availability of the drug for diversion to illicit use.

Methadone-Associated Mortality

"Three primary scenarios characterize current reports of methadone-associated mortality:
"1. In the context of legitimate patient care, methadone accumulates to harmful serum levels during the first few days of treatment for addiction or pain (that is, the induction period before methadone steady state is achieved or tolerance develops).
"2. Illicitly obtained methadone is used by some individuals who have diminished or no tolerance to opioids and who may use excessive and/or repetitive doses in an attempt to achieve euphoric effects.

Methadone Dosing

"Methadone's half-life is approximately 24 hours and leads to a long duration of action and once-a-day dosing. This feature, coupled with its slow onset of action, blunts its euphoric effect, making it unattractive as a principal drug of abuse."

Methadone Maintenance And Opioid Substitution Treatment (MMT and OST) Have Highest Probability Of Effectiveness

Methadone Maintenance And Opioid Substitution Treatment (MMT and OST) Have Highest Probability Of Effectiveness: "Of the various treatments available, Methadone Maintenance Treatment, combined with attention to medical, psychiatric and socioeconomic issues, as well as drug counseling, has the highest probability of being effective."
