CONTEXT The usual treatment for opioid-addicted youth is detoxification and counseling. Extended medication-assisted therapy may be more helpful. OBJECTIVE To evaluate the efficacy of continuing buprenorphine-naloxone for 12 weeks vs detoxification for opioid-addicted youth. DESIGN, SETTING, AND PATIENTS Clinical trial at 6 community programs from July 2003 to December 2006 including 152 patients aged 15 to 21 years who were randomized to 12 weeks of buprenorphine-naloxone or a 14-day taper (detox). INTERVENTIONS Patients in the 12-week buprenorphine-naloxone group were prescribed up to 24 mg per day for 9 weeks and then tapered to week 12; patients in the detox group were prescribed up to 14 mg per day and then tapered to day 14. All were offered weekly individual and group counseling. MAIN OUTCOME MEASURE Opioid-positive urine test result at weeks 4, 8, and 12. RESULTS The number of patients younger than 18 years was too small to analyze separately, but overall, patients in the detox group had higher proportions of opioid-positive urine test results at weeks 4 and 8 but not at week 12 (chi(2)(2) = 4.93, P = .09). At week 4, 59 detox patients had positive results (61%; 95% confidence interval [CI] = 47%-75%) vs 58 12-week buprenorphine-naloxone patients (26%; 95% CI = 14%-38%). At week 8, 53 detox patients had positive results (54%; 95% CI = 38%-70%) vs 52 12-week buprenorphine-naloxone patients (23%; 95% CI = 11%-35%). At week 12, 53 detox patients had positive results (51%; 95% CI = 35%-67%) vs 49 12-week buprenorphine-naloxone patients (43%; 95% CI = 29%-57%). By week 12, 16 of 78 detox patients (20.5%) remained in treatment vs 52 of 74 12-week buprenorphine-naloxone patients (70%; chi(2)(1) = 32.90, P < .001). During weeks 1 through 12, patients in the 12-week buprenorphine-naloxone group reported less opioid use (chi(2)(1) = 18.45, P < .001), less injecting (chi(2)(1) = 6.00, P = .01), and less nonstudy addiction treatment (chi(2)(1) = 25.82, P < .001). High levels of opioid use occurred in both groups at follow-up. Four of 83 patients who tested negative for hepatitis C at baseline were positive for hepatitis C at week 12. CONCLUSIONS Continuing treatment with buprenorphine-naloxone improved outcome compared with short-term detoxification. Further research is necessary to assess the efficacy and safety of longer-term treatment with buprenorphine for young individuals with opioid dependence.

Modafinil is a novel compound that is approved for the treatment of narcolepsy. It is now being studied as a potential treatment for cocaine dependence. Cocaine withdrawal symptoms are associated with poor clinical outcome and are likely to be reversed by modafinil. In addition, the neurotransmitter actions of modafinil are opposite to cocaine-induced neuroadaptations affecting dopamine and glutamate reward circuits. Since cocaine-dependent subjects might use cocaine during a clinical trial with modafinil, this study tested the safety of intravenous cocaine (30 mg) in combination with modafinil. Each of seven subjects received a baseline (open-label) cocaine infusion. Three subsequent cocaine infusions were administered after subjects received 4 days of low dose modafinil (200 mg/day), high dose modafinil (400 mg/day), or placebo in randomized double-blind sequences. One subject received placebo prior to all infusions. Our results indicate that co-administering modafinil and a single dose of intravenous cocaine is not associated with medical risk in terms of blood pressure, pulse, temperature, or electrocardiogram measures. Furthermore, pretreatment with modafinil did not intensify cocaine euphoria or cocaine-induced craving. In fact, cocaine euphoria was significantly blunted (P=0.02) in one of our subjective measures.

Propranolol may reduce symptoms of autonomic arousal associated with early cocaine abstinence and improve treatment outcome. This trial was an 8-week, double-blind, placebo-controlled trial of propranolol in 108 cocaine dependent subjects. The primary outcome measure was quantitative urinary benzoylecgonine levels. Secondary outcome measures included treatment retention, addiction severity index results, cocaine craving, mood and anxiety symptoms, cocaine withdrawal symptoms, and adverse events. Propranolol treated subjects had lower cocaine withdrawal symptom severity but otherwise did not differ from placebo treated subjects in any outcome measure. However, in a secondary, exploratory analysis, subjects with more severe cocaine withdrawal symptoms responded better to propranolol in comparison to placebo. In these subjects, propranolol treatment was associated with better treatment retention and lower urinary benzoylecgonine levels as compared with the placebo treatment. Propranolol may be useful only for the treatment of cocaine dependent patients with severe cocaine withdrawal symptoms.

AIMS The objective is to estimate cost, net social cost and cost-effectiveness in a clinical trial of extended buprenorphine-naloxone (BUP) treatment versus brief detoxification treatment in opioid-dependent youth. DESIGN Economic evaluation of a clinical trial conducted at six community out-patient treatment programs from July 2003 to December 2006, who were randomized to 12 weeks of BUP or a 14-day taper (DETOX). BUP patients were prescribed up to 24 mg per day for 9 weeks and then tapered to zero at the end of week 12. DETOX patients were prescribed up to 14 mg per day and then tapered to zero on day 14. All were offered twice-weekly drug counseling. PARTICIPANTS 152 patients aged 15-21 years. MEASUREMENTS Data were collected prospectively during the 12-week treatment and at follow-up interviews at months 6, 9 and 12. FINDINGS The 12-week out-patient study treatment cost was

OBJECTIVE To examine predictors of opioid abstinence in buprenorphine/naloxone (Bup/Nal)-assisted psychosocial treatment for opioid-dependent youth. METHOD Secondary analyses were performed of data from 152 youth (15-21 years old) randomly assigned to 12 weeks of extended Bup/Nal therapy or up to 2 weeks of Bup/Nal detoxification with weekly individual and group drug counseling. Logistic regression models were constructed to identify baseline and during-treatment predictors of opioid-positive urine (OPU) at week 12. Predictors were selected based on significance or trend toward significance (i.e., p < .1), and backward stepwise selection was used, controlling for treatment group, to produce final independent predictors at p ≤ .05. RESULTS Youth presenting to treatment with previous 30-day injection drug use and more active medical/psychiatric problems were less likely to have a week-12 OPU. Those with early treatment opioid abstinence (i.e., weeks 1 and 2) and those who received additional nonstudy treatments during the study were less likely to have a week-12 OPU and those not completing 12 weeks of treatment were more likely to have an OPU. CONCLUSIONS Youth with advanced illness (i.e., reporting injection drug use and additional health problems) and those receiving ancillary treatments to augment study treatment were more likely to have lower opioid use. Treatment success in the first 2 weeks and completion of 12 weeks of treatment were associated with lower rates of OPU. These findings suggest that youth with advanced illness respond well to Bup/Nal treatment and identify options for tailoring treatment for opioid-dependent youth presenting at community-based settings.
