This study evaluated the efficacy of a combination tablet formulation of buprenorphine containing 8 mg of buprenorphine and 2 mg of naloxone for every other day treatment and whether increasing the daily maintenance dose was essential for maintaining an efficacious alternate-day treatment. Twenty-six opioid-dependent outpatients completing a 16-day baseline(More)
AIMS The clinical effectiveness of buprenorphine-naloxone (bup-nx) and clonidine for opioid detoxification in in-patient and out-patient community treatment programs was investigated in the first studies of the National Institute of Drug Abuse Clinical Trials Network. DESIGN Diagnostic and Statistical Manual version IV (DSM IV)-diagnosed opioid-dependent(More)
Eight opioid-dependent individuals were maintained on daily sublingual buprenorphine (8 mg) for 28 days and assigned randomly to one of two outpatient detoxification schedules under double-blind, double-dummy conditions. The two detoxification schedules were buprenorphine gradual (36 days; N = 3) or buprenorphine rapid (12 days; N = 5). Outcome variables(More)
AIMS Information concerning the association between marijuana use and opioid dependence and its treatment is needed to determine effective clinical guidelines for addressing marijuana use among opioid abusers. SETTING AND PARTICIPANTS Marijuana use was assessed in 107 people enrolled in treatment for opioid dependence. DESIGN AND MEASUREMENT Univariate(More)
OBJECTIVE To test associations between parental drug abuse and children's problems, children of cocaine- and opiate-dependent parents were compared with demographically matched referred and nonreferred children. METHOD Cocaine- and opiate-dependent parents in treatment completed the Child Behavior Checklist for 410 children (218 boys, 192 girls) from ages(More)
The relationship among topographic brain electrical activity mapping, auditory-evoked response potentials (ERPs), plasma ethanol levels and subjective reports of intoxication was examined in 4 male volunteers. The source of the auditory P300 ERP (a measure of selective attention and memory encoding) was estimated using a recently developed computer program.(More)
The confluence of the heroin injection epidemic and the human immunodeficiency virus (HIV) infection epidemic has increased the call for expanded access to effective treatments for both conditions. Buprenorphine and methadone are now listed on the World Health Organization's Model Essential Drugs List. In France, which has the most extensive experience,(More)
Rationale: Administration of double the maintenance dose of buprenorphine has been shown to permit every-other-day dosing. Whether longer periods between dosing can be achieved is unknown. Objectives: To examine whether triple the maintenance dose can be administered every 72 h without opioid withdrawal or intoxication. Methods: Sixteen opioid-dependent(More)
This study examined how having a history of sexual, physical, or emotional abuse is related to overall functioning as assessed by the Addiction Severity Index during short-term opioid maintenance treatment with either buprenorphine/naloxone or methadone. Furthermore, the relation between abuse history and overall functioning by sex was explored.(More)
The unique pharmacology of buprenorphine at the mu-opioid receptor (i.e. high affinity, low intrinsic activity and slow dissociation) results in buprenorphine having: (1) a good safety profile, (2) low physical dependence, and (3) flexibility in dose scheduling. Early studies assessed the effectiveness of buprenorphine for the treatment of opioid dependence(More)
