Methadone

Buprenorphine Formulation

(Buprenorphine Formulation) "Buprenorphine is a long-acting partial opioid agonist91,92 that is classified as a Schedule III narcotic, in contrast to methadone and levomethadyl, which are Schedule II. Its potential advantages include a higher degree of safety than with methadone, coupled with an ameliorated withdrawal syndrome. This is due to its partial agonist property at the ?-receptor along with its being a weak antagonist at the k-receptor.93-95 It is available in a tablet form for sublingual administration and in parenteral form.

Barry McCaffrey on Methadone

(Barry McCaffrey on Methadone) "Science-based methadone maintenance treatment [MMT] helps those addicted to opiates sustain their recovery. The result is less crime, fewer emergency room admissions, more citizens working, and less suffering for families and the community. More individuals contribute in taxes instead of costing in health or imprisonment."

Factors Influencing Methadone-Related Mortality

(Factors Influencing Methadone-Related Mortality) "Still, methadone is a potent drug; fatal overdoses have been reported over the years (Baden, 1970; Gardner, 1970; Clark, et al., 1995; Drummer, et al., 1992). As with most other opioids, the primary toxic effect of excessive methadone is respiratory depression and hypoxia, sometimes accompanied by pulmonary edema and/or aspiration pneumonia (White and Irvine, 1999; Harding-Pink, 1993).

Pain Patients in Methadone Treatment

(Pain Patients in Methadone Treatment) "Pain was very prevalent in representative samples of 2 distinct populations with chemical dependency, and chronic severe pain was experienced by a substantial minority of both groups. Methadone patients differed from patients recently admitted to a residential treatment center in numerous ways and had a significantly higher prevalence of chronic pain (37% vs. 24%).

Undertreated Chronic Pain and Development of Substance Dependence

(Undertreated Chronic Pain and Development of Substance Dependence) "In our study, there was greater evidence for an association between substance use and chronic pain among inpatients than among MMTP [Methadone Maintenance Treatment Program] patients. Among inpatients, there were significant bivariate relationships between chronic pain and pain as a reason for first using drugs, multiple drug use, and drug craving. In the multivariate analysis, only drug craving remained significantly associated with chronic pain.

Frequency of Dosing with Buprenorphine

(Frequency of Dosing with Buprenorphine) The New England Journal of Medicine published a study comparing methadone with LAAM [levomethadyl acetate] and buprenorphine. According to the report, "Most of the development and evaluation research on buprenorphine has been based on daily doses. Our study used thrice-weekly doses and found that outcomes were approximately equivalent to those with either daily methadone or thrice-weekly levomethadyl acetate. Thus, thrice-weekly buprenorphine may also offer greater convenience to patients and clinic staff."

Effectiveness of OBOT

(Effectiveness of OBOT) Researchers from Yale University "investigated the use of counseling and different frequencies of medication dispensing in primary care treatment with buprenorphine-naloxone. Neither the primary outcomes (the frequency of illicit opioid use, the percentage of opioid-negative urine specimens, and the maximum number of consecutive weeks of abstinence from illicit opioids) nor the proportion of patients who completed the study differed significantly among the three groups.
