Filter by:Buprenorphine is a medication used to treat opioid addiction, but individuals who use this drug are at risk of abusing it. A buprenorphine and naloxone combination may reduce the likelihood of buprenorphine addiction. This study will evaluate the potential for abuse of buprenorphine and a buprenorphine and naloxone combination in non-dependent opioid users.
The purpose of this study is to examine the abuse liability of oxycodone and codeine in individuals with, and without, a history of prescription opioid abuse. The subjective and reinforcing effects of each drug will also be examined in the presence, and absence, of experimentally induced pain.
A randomized study is planned over 5 years to evaluate the effectiveness of the Therapeutic Workplace in promoting naltrexone ingestion and abstinence in unemployed opiate-dependent injection drug users. Participants will be offered an opioid detoxification and naltrexone induction. Participants who complete the naltrexone induction will be randomly assigned to one of two groups. Both groups will be invited to work in the Therapeutic Workplace and prescribed naltrexone for 26 weeks. The groups will differ in the contingencies imposed to work and earn salary. Work Plus Naltrexone Contingency participants will be required to ingest naltrexone to work, and will receive a brief pay decrease for missing a dose. Work Plus Naltrexone Prescription participants will be prescribed naltrexone, but will not be required to ingest it to work. This study will provide a rigorous evaluation of a novel employment-based intervention, the Therapeutic Workplace, to promote naltrexone ingestion and drug abstinence in a population of injection drug users who are at considerable risk of spreading or contracting HIV infection. Hypotheses being tested in this study are: Naltrexone ingestion will be maintained in the group exposed to the employment-based naltrexone treatment significantly more than the group exposed to usual-care treatment package. Opiate abstinence will be maintained in the group exposed to the employment-based naltrexone treatment significantly more than the group exposed to usual-care treatment package.
Previous research has shown that disulfiram, a medication sometimes used for treating alcoholism, discourages cocaine use among cocaine addicts who are undergoing methadone treatment. By blocking the enzyme dopamine beta hydroxylase (DBH), disulfiram increases levels of dopamine and produces an unpleasant sense of hyperstimulation and discomfort in cocaine users. This study will evaluate the effectiveness of disulfiram in preventing drug relapse among cocaine and opiate addicts with varying inherited levels of DBH.
Buprenorphine is a treatment for opioid dependence. Naloxone is given in addition to buprenorphine in order to limit the abuse potential that is commonly associated with buprenorphine. The purpose of this study is to determine the abuse potential of high doses of buprenorphine/naloxone in opioid dependent individuals.
Much of the HIV/AIDS epidemic is driven by transmission from or to persons addicted to opiates. Many of these individuals pass through a correctional setting each year, creating an opportunity for linkage to substance abuse treatment. The purpose of this study was to evaluate the effectiveness of initiating opiate replacement therapy prior to release from incarceration on reducing HIV risk behaviors and drug relapse. In addition, this study evaluated the effectiveness of short-term payment versus non-payment of community opiate replacement therapy immediately following release from incarceration.
Lofexidine is an experimental medication that may be beneficial in reducing opiate withdrawal symptoms, such as sleep difficulty, anxiety, and tension. The purpose of this study is to determine whether lofexidine in combination with naltrexone can improve an individual's ability to cope with stress and subsequently increase the chances of remaining abstinent from opiates.
Individuals with opioid addiction often experience serious withdrawal symptoms that may make relapse unavoidable. Tramadol, a medication that is currently used to treat pain caused by chronic conditions such as cancer or joint pain, may also be effective at reducing opioid withdrawal symptoms. This study will evaluate the effectiveness of tramadol at reducing withdrawal symptoms in individuals addicted to opioid drugs.
Cocaine addiction is a serious health problem with no available medical treatment for preventing relapse. Fluoxetine, a medication that is currently used to treat depression and anxiety disorders, may also be effective at diminishing cocaine use in individuals with severe cocaine addiction. This study will evaluate the effectiveness of fluoxetine at reducing cocaine use in individuals addicted to cocaine and opioids who are concurrently receiving methadone treatment.
The purpose of this study is to examine the acute agonist and antagonist effects of a full opioid agonist medication, an opioid antagonist medication, and a partial opioid agonist medication in individuals who have different levels of physical opioid dependence.
