BACKGROUND Despite growing concern about illicit methadone use in the US and other countries, there is little data about the prevalence and correlates of methadone use in large urban areas. We assessed the prevalence and examined correlates of lifetime and recent illicit methadone use in New York City (NYC). METHODS 1,415 heroin, crack, and cocaine users aged 15-40 years were recruited in NYC...

substance use disorder is conceptualized as a chronic relapsing condition where relapse is usually defined as the return to problematic substance use following treatment. an issue of great importance is the identification of the predictors of relapse and the development of treatments that may help prevent relapse. one of the strongest predictors of relapse is craving. the purpose of the present...

Methadone is often invoked for detoxification and maintenance of the opioid addict. We have developed and validated a sensitive and specific method for the analysis of methadone and its metabolites, 2-ethylidene-1,5-dimethyl-3, 3-diphenylpyrrolidine (EDDP) and 2-ethyl-5-methyl-3,3-diphenylpyrroline (EMDP), in human plasma, urine, and liver microsomes. This assay uses a solid-phase extraction. S...

conclusions it seems matrix group interventions increase the effectiveness of methadone treatment by reducing the relapse prevention, the dose of methadone and remaining in treatment. results results showed that the effect of matrix group interventions on reducing relapse (p < 0.05), increasing the maintenance of treatment (p < 0.01), increasing the treatment compliance, reducing anger, anxiety...

OBJECTIVE Priapism is defined by persistent, painful penile erection which occurs without sexual stimulation. Methadone is used as an analgesic and is also used in detoxification and maintenance protocol for opioid dependence treatment. Here we will report a case of a male with priapism after rapid discontinuation doses of methadone. CASE PRESENTATION The case was a young married male who ref...

BACKGROUND Opioid dependence is a significant public health problem associated with high risk for relapse if treatment is not ongoing. While maintenance on opioid agonists (i.e., methadone, buprenorphine) often produces favorable outcomes, detoxification followed by treatment with the μ-opioid receptor antagonist naltrexone may offer a potentially useful alternative to agonist maintenance for s...

This study examined the uses of diverted methadone and buprenorphine among opiate-addicted individuals recruited from new admissions to methadone programs and from out-of-treatment individuals recruited from the streets. Self-report data regarding diversion were obtained from surveys and semi-structured qualitative interviews. Approximately 16% (n = 84) of the total sample (N = 515) reported us...

People addicted to heroin often require prescribed medication when attempting to cease their drug use. The most commonly used detoxification agents in UK prisons are buprenorphine, dihydrocodeine and methadone. However, national guidelines do not state a det...
