    Methadone, a pharmacological agent used to treat heroin dependence is relatively safe, but may cause cardiac arrhythmias in the concurrent presence of other risk factors. APPROACH AND KEY FINDINGS: This case report highlights the risk of torsade de pointes, a life-threatening cardiac arrhythmia, in a heroin-dependent patient receiving methadone substitution therapy who was prescribed itraconazole for vaginal thrush. The patient presented to the accident and emergency department for chest discomfort and an episode of syncope following two doses of itraconazole (200 mg). Electrocardiogram monitoring at the accident and emergency department showed prolonged rate-corrected QT interval leading to torsade de pointes. The patient was admitted for cardiac monitoring, and electrocardiogram returned to normal upon discontinuation of methadone.

    BACKGROUND: The commencement of methadone maintenance therapy (MMT) in 2005 represents a quantum leap in the management of heroin dependence in Malaysia.
    OBJECTIVE: To examine the 2-year outcomes of this modality in the treatment of heroin dependence with respect to the quality of life (QOL), heroin abstinence, and rate of employment among heroin dependants attending the Tengku Ampuan Afzan Hospital (HTAA) MMT clinic.
    METHOD: This was an experimental study in which the second QOL assessment was conducted 2 years after treatment initiation.
    RESULTS: A total of 172 patients enrolled at the point of entry to the MMT program. The authors examined 107 patients who remained in the program 2 years later (62.6% retention rate). A paired t test demonstrated significant improvements in all 4 domains of QOL (physical, psychological, social relationships, and environment; P < .001). The most marked improvement was noted in the psychological domain.
    CONCLUSION: The MMT program at HTAA is effective in improving the QOL among heroin dependants.

    AIMS: To aid public health policymaking, we studied the cost-effectiveness of buprenorphine, naltrexone, and placebo interventions for heroin dependence in Malaysia.

    DESIGN: We estimated the cost-effectiveness ratios of three treatments for heroin dependence. We used a microcosting methodology to determine fixed, variable, and societal costs of each intervention. Cost data were collected from investigators, staff, and project records on the number and type of resources used and unit costs; societal costs for participants' time were estimated using Malaysia's minimum wage. Costs were estimated from a provider and societal perspective and reported in 2004 US dollars.

    SETTING: Muar, Malaysia.

    PARTICIPANTS: 126 patients enrolled in a randomized, double-blind, placebo-controlled clinical trial in Malaysia (2003-2005) receiving counseling and buprenorphine, naltrexone, or placebo for treatment of heroin dependence.

    MEASUREMENTS: Primary outcome measures included days in treatment, maximum consecutive days of heroin abstinence, days to first heroin use, and days to heroin relapse. Secondary outcome measures included treatment retention, injection drug use, illicit opiate use, AIDS Risk Inventory total score, and drug risk and sex risk subscores.

    FINDINGS: Buprenorphine was more effective and more costly than naltrexone for all primary and most secondary outcomes. Incremental cost-effectiveness ratios were below $50 for primary outcomes, mostly below $350 for secondary outcomes. Naltrexone was dominated by placebo for all secondary outcomes at almost all endpoints. Incremental treatment costs were driven mainly by medication costs, especially the price of buprenorphine.

    CONCLUSIONS: Buprenorphine appears to be a cost-effective alternative to naltrexone that might enhance economic productivity and reduce drug use over a longer term.

    BACKGROUND: This paper describes the rationale, implementation and operation of a "world first" Islamic inspired methadone maintenance treatment project delivered in a mosque setting and presents the outcome for the first group of participants. The project explored the viability of expanding addiction recovery services through the network of mosques in Muslim communities.
    METHODS: The project combined methadone maintenance with peer and religious counseling. Participants consisted of 36 male Muslim heroin users who went through the project. Urine tests and self-reported measures on various dimensions relevant to drug use and quality of life were collected at baseline and 12 months.
    RESULTS: The project had a 12 month retention rate of 80%. At 12 months all but one participant tested negative for opioids and other substances. Self-report measures showed significant reductions in the degree and variety of drug use, improvements in general health, and psychological and social functioning of participants. Qualitative data showed that availability of methadone, convenient location and religion were the main reasons drawing participants to the program.
    CONCLUSIONS: Mosques are viable venues for offering medication assisted recovery services and offer an alternative approach for managing addiction in Muslim communities. The prospect of mobilizing community resources to offer community-oriented long-term recovery management programs in mosques and other places of worship deserves consideration.

    A young male presented with many years of delusions and hallucinations, with concurrent heroin use and subsequent amphetamine uses. There were no depressive or manic symptoms and psychotic symptoms prior to the amphetamine use. After the trials of two atypical antipsychotics and later clozapine due to treatment resistance, adherence and functionality were poor and there was still persistent drug use. As a result, a long acting injectable adjunct was commenced, but only minimal effects were observed. However after initiation of directly observed treatment of clozapine with methadone, there has been functional and clinical response and drug use has ceased.

    INTRODUCTION: Methadone has long been regarded as an effective treatment for opioid dependence. However, many patients discontinue maintenance therapy because of its side effects, with one of the most common being sexual dysfunction. Buprenorphine is a proven alternative to methadone. This study aimed to investigate sexual dysfunction in opioid-dependent men on buprenorphine maintenance treatment (BMT) and methadone maintenance treatment (MMT). The secondary aim was to investigate the correlation between sexual dysfunction and the quality of life in these patients.

    METHODS: Two hundred thirty-eight men participated in this cross-sectional study. Four questionnaires were used, the Mini International Neuropsychiatric Interview, Opiate Treatment Index, Malay version of the International Index of Erectile Function 15 (Mal-IIEF-15), and World Health Organization Quality of Life-BREF Scale. Multivariate analysis of covariance was used to examine the relationship between MMT and BMT and the Mal-IIEF 15 scores while controlling for all the possible confounders.

    RESULTS: The study population consisted of 171 patients (71.8%) on MMT and 67 (28.2%) on BMT. Patients in the MMT group who had a sexual partner scored significantly lower in the sexual desire domain (p < 0.012) and overall satisfaction (p = 0.043) domain compared with their counterparts in the BMT group. Similarly, patients in the MMT group without a sexual partner scored significantly lower in the orgasmic function domain (p = 0.008) compared with those in the BMT group without a partner. Intercourse satisfaction (p = 0.026) and overall satisfaction (p = 0.039) were significantly associated with the social relationships domain after adjusting for significantly correlated sociodemographic variables.

    CONCLUSIONS: Sexual functioning is critical for improving the quality of life in patients in an opioid rehabilitation program. Our study showed that buprenorphine causes less sexual dysfunction than methadone. Thus, clinicians may consider the former when treating heroin dependents who have concerns about sexual function.

    Expansion of access to effective treatments for heroin dependence is a worldwide health priority that will also reduce HIV transmission. We compared the efficacy of naltrexone, buprenorphine, and no additional treatment, in patients receiving detoxification and subsequent drug counselling, for maintenance of heroin abstinence, prevention of relapse, and reduction of HIV risk behaviours.

    Drugs with complex pharmacology are used in the management of drug use disorder (DUD) and HIV/AIDS in Malaysia and in parts of South-East Asia. Their multiethnic populations suggest complexity due to the genetic polymorphism, such as CYP2B6 that metabolizes methadone and anti-retroviral.

    Methadone as the most prevalent opioid substitution medication has been shown to influence the neurophysiological functions among heroin addicts. However, there is no firm conclusion on acute neuroelectrophysiological changes among methadone-treated subjects as well as the effectiveness of methadone in restoring brain electrical abnormalities among heroin addicts. This study aims to investigate the acute and short-term effects of methadone administration on the brain's electrophysiological properties before and after daily methadone intake over 10 weeks of treatment among heroin addicts. EEG spectral analysis and single-trial event-related potential (ERP) measurements were used to investigate possible alterations in the brain's electrical activities, as well as the cognitive attributes associated with MMN and P3. The results confirmed abnormal brain activities predominantly in the beta band and diminished information processing ability including lower amplitude and prolonged latency of cognitive responses among heroin addicts compared to healthy controls. In addition, the alteration of EEG activities in the frontal and central regions was found to be associated with the withdrawal symptoms of drug users. Certain brain regions were found to be influenced significantly by methadone intake; acute effects of methadone induction appeared to be associative to its dosage. The findings suggest that methadone administration affects cognitive performance and activates the cortical neuronal networks, resulting in cognitive responses enhancement which may be influential in reorganizing cognitive dysfunctions among heroin addicts. This study also supports the notion that the brain's oscillation powers and ERPs can be utilized as neurophysiological indices for assessing the addiction treatment traits.
