In October 2002, the U.S. Food and Drug Administration approved buprenorphine-naloxone (Suboxone ® ) sublingual tablets as an opioid dependence treatment available for use outside traditionally licensed opioid treatment programs. The NIDA Center for Clinical Trials Network (CTN) sponsored two clinical trials assessing buprenorphine-naloxone for short-term opioid detoxification. These trials provided an unprecedented field test of its use in twelve diverse community-based treatment programs. Opioid-dependent men and women were randomized to a thirteen-day buprenorphine-naloxone taper regimen for short-term opioid detoxification. The 234 buprenorphine-naloxone patients averaged 37 years old and used mostly intravenous heroin. Direct and rapid induction onto buprenorphine-naloxone was safe and well tolerated. Most patients (83%) received 8 mg buprenorphine-2 mg naloxone on the first day and 90% successfully completed induction and reached a target dose of 16mg buprenorphine-4 mg naloxone in three days. Medication NIH-PA Author ManuscriptNIH-PA Author Manuscript NIH-PA Author Manuscript compliance and treatment engagement was high. An average of 81% of available doses was ingested, and 68% of patients completed the detoxification. Most (80.3%) patients received some ancillary medications with an average of 2.3 withdrawal symptoms treated. The safety profile of buprenorphine-naloxone was excellent. Of eighteen serious adverse events reported, only one was possibly related to buprenorphine-naloxone. All providers successfully integrated buprenorphinenaloxone into their existing treatment milieus. Overall, data from the CTN field experience suggest that buprenorphine-naloxone is practical and safe for use in diverse community treatment settings, including those with minimal experience providing opioid-based pharmacotherapy and/or medical detoxification for opioid dependence.Opioid dependence and its associated disorders represent a serious public health problem in the United States and many other countries. Less than 20% of an estimated 898,000 U.S. heroin users 1 currently receive agonist treatment with methadone or LAAM. Further, sales and distribution of LAAM in the United States were discontinued in August 2003 as a result of severe cardiac-related adverse events associated with its use. Even fewer users receive antagonist treatment with naltrexone or some type of medical detoxification, followed by additional treatment such as that provided through a therapeutic community, short-term residential program, or drug-free outpatient program. Although each of these treatments can be effective, their availability and attractiveness to patients vary and are not sufficient to meet the current demand for treatment. The reasons are complex but include inadequate resources for patients to pay for current care, community resistance to new drug treatment programs (especially methadone), patient preference, and regulatory barriers that limit access to treatment.Buprenorphine hydrochloride (HCl), a derivative of the morp...

The purpose of this study was to investigate whether asynchronous video posts and synchronous videoconferencing would create higher levels of teaching and social presence within an online course when compared with the university's current text-based discussion platform. Undergraduate students in an online teacher education course were randomly assigned to either the text-based discussion platform or the video-based discussion platform. A switched replications design was used and halfway through the semester students switched platforms. Analysis of student interviews and surveys administered at the end of the semester indicated self-reported perceptions of social and teaching presence were significantly higher when using the video-enabled discussion site. Implications of the added value of video, both in synchronous and asynchronous contexts, are discussed and recommendations for further study are provided.

A feasibility study was conducted to pilot test the ability of five sites to recruit, treat, and retain opioid-dependent offenders in a trial of extended-release injectable naltrexone (XR-NTX). The participants, 61 previously opioid-dependent individuals under legal supervision in the community, received up to six monthly injections of Depotrex® brand naltrexone and completed a six-month follow-up interview. Six-month outcomes showed that those who completed treatment had significantly fewer opioid-positive urines and were less likely to have been incarcerated than those who had not completed treatment. The findings indicate that XR-NTX holds promise as a feasible, effective treatment option for opioid-dependent offenders.
