Determinants of health-related quality of life among individuals with opioid use disorder, recently released from incarceration.

BACKGROUND\OBJECTIVES: Concomitant with low rates of pharmacotherapy for incarcerated individuals with OUD, there is a high rate of opioid overdose following re-entry into the community. Our research objective was to develop a better understanding of the factors that influence health-related quality-of-life (HRQoL) among this population during the high-risk transition period from incarceration to community. Few studies have assessed health-related quality-of-life (HRQoL) among individuals with OUD who are involved with the criminal-legal system, let alone over the period directly surrounding release from incarceration. METHODS: Secondary longitudinal analysis of data from a clinical trial where participants were randomized 1:1 to pre-release extended-release naltrexone (XR-NTX) + referral to community XR-NTX, vs. referral only. We conducted individual, multivariable regressions of EQ-5D domains (mobility, pain/discomfort, anxiety/depression; usual activities and self-care were excluded due to insufficient variation in scores), and the overall preference/utility score. HRQoL data were subset to timepoints immediately before release (baseline) and 12 weeks post-release; treatment groups were collapsed across condition. Multiple imputation by chained equations was conducted to handle missing 3-month data in the dependent variables and covariates, ad hoc. RESULTS: Greater severity in the psychiatric composite score was associated with substantially lower HRQoL, across all measures, following release from incarceration. Greater severity in the medical composite score was associated with lower pain/discomfort-related HRQoL. CONCLUSIONS: Our findings highlight the importance of ensuring individuals with OUD are linked not only to MOUD, but also treatment for their comorbid conditions upon release from incarceration.

Cost-effectiveness of extended-release injectable naltrexone among incarcerated persons with opioid use disorder before release from prison versus after release.

INTRODUCTION: Opioid use disorder (OUD) is highly prevalent among incarcerated populations, and the risk of fatal overdose following release from prison is substantial. Despite efficacy, few correctional facilities provide evidence-based addiction treatment. Extended-release injectable naltrexone (XR-NTX) administered prior to release from incarceration may improve health and economic outcomes. METHODS: We conducted an economic evaluation alongside a randomized controlled trial testing the effectiveness of XR-NTX before release from prison (n = 38) vs. XR-NTX referral after release (n = 48) of incarcerated participants with OUD, both groups continuing treatment at a community addiction treatment center. The incremental cost-effectiveness ratio (ICER) assessed the cost-effectiveness of XR-NTX before release compared to referral after release for three stakeholder perspectives at 12- and 24-week periods: state policymaker, health care sector, and societal. Effectiveness measures included quality-adjusted life-years (QALYs) and abstinent years from opioids. In addition, we categorized resources as OUD-related and non-OUD-related medical care, state transfer payments, and other societal costs (productivity, criminal justice resources, etc.). RESULTS: Results showed an association between XR-NTX and greater OUD-related costs and total costs from the state policymaker perspective. QALYs gained were positive but statistically insignificant between arms; however, results showed XR-NTX had an estimated 15.5 more days of opioid abstinence over 24 weeks and statistically significant at a 95 % confidence level based on the distribution of bootstrapped samples. We found that estimated ICERs to be > $500,000 per QALY for all stakeholder perspectives. For the abstinent-year effectiveness measure, we found XR-NTX before release to be cost-effective at a 95 % confidence level for willingness-to-pay values >$49,000 per abstinent-year, across all perspectives. CONCLUSIONS: XR-NTX administered to persons who are incarcerated with OUD before release may provide value for stakeholders and bridge a well-known treatment gap for this vulnerable population. Lower than expected participant engagement and missing data limit our results, and study outcomes may be sensitive to methods that address missing data if replicated.

Extended release injectable naltrexone before vs. after release: A randomized trial of opioid addicted persons who are in prison.

BACKGROUND: Usual treatment for persons with opioid use disorders who are in prison is detoxification with referral to treatment after release but failure to engage in treatment and relapse is common. Starting medication treatment before release might improve outcomes. OBJECTIVES: Determine if administering extended-release injectable naltrexone (XR-NTX) before release (BR) from prison results in less relapse within the first three months after release than when offered by referral after release (AR). METHODS: The study randomized 1:1 persons who had an OUD, expressed interest in XR-NTX, and met study admission criteria to receive XR-NTX BR or at a local program AR, with continued medication and counseling available at that program. RESULTS: Four-hundred and two persons expressed interest in the study, 222 consented, and the study randomized 146. Uncertainty about release dates resulted in a time lag between randomization and final disposition during which 60 of the randomized patients were sentenced to other facilities, withdrew consent, or became otherwise unavailable for study treatment, leaving 86 for outcome analyses (38, BR; 48 AR). Missed follow-up appointments on the remaining 86 led to development of a phone-based questionnaire to determine presence/absence of relapse. Using it to supplement other data, we were able to confirm relapse or nonrelapse for 63 of the 86 (73%). All BR and a third of the AR patients received their first XR-NTX dose, however dropout was high and nonrelapse by month three was not significantly different between BR (39.5%) and AR (25%) (Chisq (2) = 3.23, p = 0.20). CONCLUSIONS: BR patients were much more likely to receive medication and its extended relapse and overdose protection effects in the first weeks after release. Dropout was high and the study detected no significant difference in relapse by month 3; however, the less-than-planned number of patients and missing data make this finding inconclusive.

Health and economic outcomes of treatment with extended-release naltrexone among pre-release prisoners with opioid use disorder (HOPPER): protocol for an evaluation of two randomized effectiveness trials.

BACKGROUND: Persons with an opioid use disorder (OUD) who were incarcerated face many challenges to remaining abstinent; concomitantly, opioid-overdose is the leading cause of death among this population, with the initial weeks following release proving especially fatal. Extended-release naltrexone (XR-NTX) is the most widely-accepted, evidence-based OUD pharmacotherapy in criminal justice settings, and ensures approximately 30 days of protection from opioid overdose. The high cost of XR-NTX serves as a barrier to uptake by many prison/jail systems; however, the cost of the medication should not be viewed in isolation. Prison/jail healthcare budgets are ultimately determined by policymakers, and the benefits/cost-offsets associated with effective OUD treatment will directly and indirectly affect their overall budgets, and society as a whole. METHODS: This protocol describes a study funded by the National Institute of Drug Abuse (NIDA) to: evaluate changes in healthcare utilization, health-related quality-of-life, and other resources associated with different strategies of XR-NTX delivery to persons with OUD being released from incarceration; and estimate the relative "value" of each strategy. Data from two ongoing, publicly-funded, randomized-controlled trials will be used to evaluate these questions. In Study A, (XR-NTX Before vs. After Reentry), participants are randomized to receive their first XR-NTX dose before release, or at a nearby program post-release. In Study B, (enhanced XR-NTX vs. XR-NTX), both arms receive XR-NTX prior to release; the enhanced arm receives mobile medical (place of residence) XR-NTX treatment post-release, and the XR-NTX arm receives referral to a community treatment program post-release. The economic data collection instruments required to evaluate outcomes of interest were incorporated into both studies from baseline. Moreover, because the same instruments are being used in both trials on comparable populations, we have the opportunity to not only assess differences in outcomes between study arms within each trial, but also to merge the data sets and test for differences across trials. DISCUSSION: Initiating XR-NTX for OUD prior to release from incarceration may improve patient health and well-being, while also producing downstream cost-offsets. This study offers the unique opportunity to assess the effectiveness and cost-effectiveness of multiple strategies, according to different stakeholder perspectives.

Slow-release naltrexone implant versus oral naltrexone for improving treatment outcomes in people with HIV who are addicted to opioids: a double-blind, placebo-controlled, randomised trial.

BACKGROUND: Untreated opioid addiction in people with HIV is associated with poor HIV treatment outcomes. Slow-release, long-acting, implantable naltrexone might improve these outcomes. Here, we present results of a study aimed to test this hypothesis. METHODS: We did a 48 week double-blind, double-dummy, placebo-controlled, phase 3, randomised trial with men and women addicted to opioids who were starting antiretroviral therapy (ART) for HIV and whose viral loads were higher than 1000 copies per mL. Participants were seeking treatment at two HIV and two narcology programme centres in Saint Petersburg, Russia, and the surrounding Leningrad region. The Pavlov statistical department created a table with stratification on gender distribution, viral load, and CD4 cell count. We stratified participants according to gender, viral load, and CD4 cells per µL, and randomly assigned (1:1) them to addiction treatment with a naltrexone implant and oral naltrexone placebo (implant group) or oral naltrexone and placebo implant (oral group). The primary outcome was plasma viral load of less than 400 copies per mL at 24 weeks and 48 weeks. We included all randomly assigned participants in outcome analyses (intention to treat). Treatment staff and patients were masked to group assignment. The study is complete and registered at ClinicalTrials.gov, NCT01101815. FINDINGS: Between July 14, 2011, and April 14, 2014, 238 potential participants were recruited and screened, 35 were excluded for not meeting inclusion criteria, three declined to participate, and 200 were randomly assigned to treatment (100 to each group). At week 24, 38 (38) participants in the implant group and 35 (35%) in the oral group had viral loads less than 400 copies per mL (risk ratio 1·1, 95% CI 0·76-1·56; p=0·77). At week 48, 66 participants in the implant group and 50 in the oral group had viral loads less than 400 copies per mL (risk ratio 1·32, 95% CI 1·04-1·68; p=0·045). There were seven serious adverse events: three deaths in the implant group (one due to heart disease, one trauma, and one AIDS), and four in the oral group (two overdoses, one pancreatic cancer, and one AIDS). The overdose deaths occurred 9-10 months after the last naltrexone dose. INTERPRETATION: The longer the blockade of opioid effects, the more protection an individual gets from missed ART doses and impulsive behaviours that lead to relapse and poor, even fatal, outcomes. Commercial development of implants could result in a meaningful addition to addiction treatment options.

Presence or Absence of QTc Prolongation in Buprenorphine-Naloxone Among Youth With Opioid Dependence.

OBJECTIVES: The aim of the study was to evaluate buprenorphine-naloxone effects on the QTc in youth with opioid dependence. Buprenorphine is a partial agonist that is an effective treatment for opioid dependence. Compared with methadone, it has a lower risk of QTc prolongation in adults, but is less studied in the youth. It may also reduce the risk of torsades de pointes (TdP)--an uncommon variant of polymorphic ventricular tachycardia--that can result in syncope, ventricular fibrillation, and sudden death. METHODS: Secondary analysis of the electrocardiogram data from 95 individuals who participated in a multisite trial for youth with opioid dependence. The participants were randomized to a 2-week (DETOX) or a 12-week course of buprenorphine-naloxone (BUP). At baseline, 12-lead electrocardiograms were done at weeks 4 and 12, and QTc intervals were hand-measured and calculated using Bazett formula. Increases above 60 milliseconds were considered clinically significant, and readings above 450 milliseconds (in men) and 470 milliseconds (in women) indicated a prolonged QTc. RESULTS: Mean QTc intervals were higher for BUP than for DETOX participants at baseline, week 4, and week 12 (P = 0.045), and women had longer mean QTc intervals than men (P < 0.0005). Variations in the QTc intervals were observed in some; however, none were above 500 milliseconds--the level at which risk for TdP becomes more significant. CONCLUSIONS: In this randomized trial, the mean QTc at baseline, before randomization, was higher in BUP than in DETOX patients. Minimal changes in the QTc were seen at 4 and 12 weeks in a few patients in both groups. There was no evidence that buprenorphine-naloxone alone increased the QTc to a level that increased the risk for TdP.

Opioid addicted buprenorphine injectors: drug use during and after 12-weeks of buprenorphine-naloxone or methadone in the Republic of Georgia.

AIMS: The aim of this study is to assess the prevalence of non-opioid drug use among opioid-addicted, buprenorphine injecting individuals in Georgia, during and after a 12-week course of buprenorphine-naloxone (Suboxone®) or methadone. METHODS: Randomized controlled trial with daily observed Suboxone® or methadone and weekly counseling, urine tests and timeline followback (TLFB) in weeks 0-12 and 20, and the Addiction Severity Index (ASI) at weeks 0, 4, 8, 12, 20. RESULTS: Of the 80 patients (40/group, 4 women), 68 (85%) completed the 12-weeks of study treatment and 66 (82.5%) completed the 20-week follow-up. At baseline, injecting more than one drug in the last 30 days was reported by 68.4% of patients in the methadone and 72.5% in the Suboxone® groups. Drug use was markedly reduced in both treatment conditions but there were significant differences in the prevalence of specific drugs with more opioid (1.5 vs. 0.2%; p=0.03), less amphetamine (0.2 vs. 2.8%; p<0.001) and less marijuana (1.7 vs. 10.2%; p<0.001) positive urine tests in the methadone vs. Suboxone® groups. At the 20-week follow-up, TLFB results on the 34 that continued methadone or the 3 on Suboxone® showed less opioid (5.6 vs. 27.6%; p<0.001), illicit buprenorphine (2.7 vs. 13.8%; p=0.005), benzodiazepine (13.5 vs. 34.5%; p<0.001), and marijuana (2.8 vs. 20.7%; p<0.001) use than the 29 who did not continue opioid substitution therapy. CONCLUSIONS: Despite small but significant differences in opioid and other drug use, both treatments were highly effective in reducing opioid and non-opioid drug use.

HIV risk reduction with buprenorphine-naloxone or methadone: findings from a randomized trial.

OBJECTIVES: Compare HIV injecting and sex risk in patients being treated with methadone (MET) or buprenorphine-naloxone (BUP). METHODS: Secondary analysis from a study of liver enzyme changes in patients randomized to MET or BUP who completed 24 weeks of treatment and had 4 or more blood draws. The initial 1:1 randomization was changed to 2:1 (BUP:MET) after 18 months due to higher dropout in BUP. The Risk Behavior Survey measured HIV risk before 30 days at baseline and weeks 12 and 24. RESULTS: Among 529 patients randomized to MET, 391 (74%) were completers; among 740 randomized to BUP, 340 (46%) were completers; 700 completed the Risk Behavior Survey. There were significant reductions in injecting risk (P < 0.0008) with no differences between groups in mean number of times reported injecting heroin, speedball, other opiates, and number of injections; or percent who shared needles; did not clean shared needles with bleach; shared cookers; or engaged in front/back loading of syringes. The percent having multiple sex partners decreased equally in both groups (P < 0.03). For males on BUP, the sex risk composite increased; for males on MET, the sex risk decreased resulting in significant group differences over time (P < 0.03). For females, there was a significant reduction in sex risk (P < 0.02) with no group differences. CONCLUSIONS: Among MET and BUP patients who remained in treatment, HIV injecting risk was equally and markedly reduced; however, MET retained more patients. Sex risk was equally and significantly reduced among females in both treatment conditions, but it increased for males on BUP and decreased for males on MET.

Methadone and buprenorphine-naloxone are effective in reducing illicit buprenorphine and other opioid use, and reducing HIV risk behavior--outcomes of a randomized trial.

AIMS: Determine the extent to which buprenorphine injectors continue treatment with buprenorphine-naloxone or methadone, and the impact of these treatments on substance use and HIV risk in the Republic of Georgia. METHODS: Randomized controlled 12-week trial of daily-observed methadone or buprenorphine-naloxone followed by a dose taper, referral to ongoing treatment, and follow-up at week 20 at the Uranti Clinic in Tbilisi, Republic of Georgia. Eighty consenting treatment-seeking individuals (40/group) aged 25 and above who met ICD-10 criteria for opioid dependence with physiologic features and reported injecting buprenorphine 10 or more times in the past 30 days. Opioid use according to urine tests and self-reports, treatment retention, and HIV risk behavior as determined by the Risk Assessment Battery. RESULTS: Mean age of participants was 33.7 (SD5.7), 4 were female, mean history of opioid injection use was 5.8 years (SD4.6), none were HIV+ at intake or at the 12-week assessment and 73.4% were HCV+. Sixty-eight participants (85%) completed the 12-week medication phase (33 from methadone and 35 from buprenorphine/naloxone group); 37 (46%) were in treatment at the 20-week follow-up (21 from methadone and 16 from the buprenorphine/naloxone group). In both study arms, treatment resulted in a marked reduction in unprescribed buprenorphine, other opioid use, and HIV injecting risk behavior with no clinically significant differences between the two treatment arms. CONCLUSIONS: Daily observed methadone or buprenorphine-naloxone are effective treatments for non-medical buprenorphine and other opioid use in the Republic of Georgia and likely to be useful for preventing HIV infection.

Predictors of attrition with buprenorphine/naloxone treatment in opioid dependent youth.

BACKGROUND: In opioid dependent youth there is substantial attrition from medication-assisted treatment. If youth at risk for attrition can be identified at treatment entry or early in treatment, they can be targeted for interventions to help retain them in treatment. METHODS: Opioid dependent adolescents and young adults (n=152), aged 15-21, were randomized to 12 weeks (BUP, n=74) or 2 weeks of detoxification (DETOX, n=78) with buprenorphine/naloxone (Bup/Nal), both in combination with 12 weeks of psychosocial treatment. Baseline and early treatment related predictors of treatment attrition were identified in each group using bivariate and multivariate logistic regression. RESULTS: In the DETOX group 36% left between weeks 2 and 4, at the end of the dose taper, while in the BUP group only 8% left by week 4. In the BUP group, early adherence to Bup/Nal, early opioid negative urines, use of any medications in the month prior to treatment entry, and lifetime non-heroin opioid use were associated with retention while prior 30-day hallucinogen use was associated with attrition. In the DETOX group, only use of sleep medications was associated with retention although not an independent predictor. A broad range of other pre-treatment characteristics was unrelated to attrition. CONCLUSIONS: Prompt attention to those with early non-adherence to medication or an early opioid positive urine, markers available in the first 2 weeks of treatment, may improve treatment retention. Extended Bup/Nal treatment appeared effective in improving treatment retention for youth with opioid dependence across a wide range of demographics, and pre-treatment clinical characteristics.

Predictors of abstinence: National Institute of Drug Abuse multisite buprenorphine/naloxone treatment trial in opioid-dependent youth.

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.

Cost-effectiveness of extended buprenorphine-naloxone treatment for opioid-dependent youth: data from a randomized trial.

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 $1514 (P < 0.001) higher for BUP relative to DETOX. One-year total direct medical cost was only $83 higher for BUP (P = 0.97). The cost-effectiveness ratio of BUP relative to DETOX was $1376 in terms of 1-year direct medical cost per quality-adjusted life year (QALY) and $25,049 in terms of out-patient treatment program cost per QALY. The acceptability curve suggests that the cost-effectiveness ratio of BUP relative to DETOX has an 86% chance of being accepted as cost-effective for a threshold of $100,000 per QALY. CONCLUSIONS: Extended BUP treatment relative to brief detoxification is cost effective in the US health-care system for the outpatient treatment of opioid-dependent youth.

HIV risk behavior in treatment-seeking opioid-dependent youth: results from a NIDA clinical trials network multisite study.

OBJECTIVE: To assess baseline rates of and changes in HIV drug and sexual risk behavior as a function of gender and treatment in opioid-dependent youth. METHODS: One hundred fifty participants were randomly assigned to extended buprenorphine/naloxone therapy (BUP) for 12 weeks or detoxification for 2 weeks; all received drug counseling for 12 weeks. HIV risk was assessed at baseline and 4-week, 8-week, and 12-week follow-ups. Behavioral change was examined using generalized estimating equations. RESULTS: Baseline rates of past-month HIV risk for females/males were 51%/45% for injection drug use (IDU) (ns), 77%/35% for injection risk (P < 0.001), 82%/74% for sexual activity (ns), 14%/24% for multiple partners (ns), and 68%/65% for unprotected intercourse (ns). IDU decreased over time (P < 0.001), with greater decreases in BUP versus detoxification (P < 0.001) and females versus males in BUP (P < 0.05). Injection risk did not change for persistent injectors. Sexual activity decreased in both genders and conditions (P < 0.01), but sexual risk did not. CONCLUSIONS: Overall, IDU and sexual activity decreased markedly, particularly in BUP patients and females, but injection and sexual risk behaviors persisted. Although extended BUP seems to have favorable effects on HIV risk behavior in opioid-dependent youth, risk reduction counseling may be necessary to extend its benefits.

Extended vs short-term buprenorphine-naloxone for treatment of opioid-addicted youth: a randomized trial.

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.

Why patients sign out against medical advice (AMA): factors motivating patients to sign out AMA.

A retrospective review of the against medical advice (AMA) discharges revealed that the majority of the patients left AMA for personal reasons, i.e., sickness or death in the family; reconciliation with spouse, girl friend, or family members; financial problems; and legal issues such as a court date. Strategies to reduce AMA discharges and increase patient retention in treatment are suggested.

Modafinil and cocaine: a double-blind, placebo-controlled drug interaction study.

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.

A pilot trial of piracetam and ginkgo biloba for the treatment of cocaine dependence.

BACKGROUND: Chronic cocaine use is associated with cognitive deficits that may reduce the effectiveness of psychosocial treatment and promote relapse in newly abstinent cocaine-dependent patients. Nootropic agents, such as piracetam and ginkgo biloba, may improve cognitive function and reduce the incidence of relapse in these patients. METHODS: This was a 10-week, double-blind, placebo-controlled pilot trial involving 44 cocaine-dependent subjects. Subjects received either piracetam (4.8 g/day), ginkgo biloba (120 mg/day), or placebo. Subjects were required to attain abstinence from cocaine during a 2-week baseline phase demonstrated by providing at least one benzoylecgonine (BE)-negative urine toxicology screen. Outcome measures included treatment retention, urine toxicology screens, Clinical Global Impression (CGI) scores, and results from the Addiction Severity Index (ASI). RESULTS: Ginkgo biloba was not superior to placebo in any outcome measure. Piracetam was associated with more cocaine use and lower CGI scores compared to placebo. CONCLUSIONS: Neither piracetam nor ginkgo biloba appears to be a promising medication for the treatment of cocaine dependence.

A randomized, double-blind, placebo-controlled safety study of high-dose dextromethorphan in methadone-maintained male inpatients.

The NMDA antagonist dextromethorphan hydrobromide (DM) may be useful in the treatment of opioid dependence, particularly as a means of reducing tolerance to methadone during replacement therapy. As a prelude to clinical efficacy studies, a randomized, double-blind, placebo-controlled study examined the safety of DM in combination with methadone in inpatient, opiate-dependent volunteers. Male participants received daily methadone (50-70 mg/day) and either DM (n=10) or placebo (n=5) during the 12-day active medication phase of the study. DM participants received doses of 120, 240, and 480 mg/day in increasing order (4 days each). DM at high doses caused mild elevations of heart rate, blood pressure, temperature, and plasma bromide. However, none of these effects was clinically significant. DM caused no significant changes in respiration, pupil diameter, or subjective drug effects measured by standard scales. Participants in the DM group reported many more adverse events than did subjects on placebo (173 vs. 21), but these effects were not clinically serious. The most commonly reported side effects were sleepiness and drowsiness. Several participants reported intoxicating effects at the highest dose. Overall, DM was well-tolerated by the methadone-maintained opiate-dependent subjects studied here. These results support the further exploration of DM as an adjunct medication during methadone replacement therapy.
