Active clinical trials for "Opioid-Related Disorders"

A randomized clinical trial evaluating whether Behavioral Drug and HIV Risk Reduction Counseling (BDRC), abstinence-contingent take-home buprenorphine (ACB), or the combination of the two improve efficacy and cost-effectiveness of standard buprenorphine treatment for opiate-dependent individuals in Malaysia.

Managed detoxification is a first and necessary step prior to treatment and rehabilitation. Detoxification can be a major obstacle for some patients, and the availability of managed and safe withdrawal is a prerequisite for long-term treatment. In our clinical practice we have felt the need for a standardised and safe detoxification treatment regimen for our opioid addicts, as dependence on multiple drugs is so common. Objectives To assess whether a novel standardised treatment regimen - Buprenorphine (BPN) combined with Valproate (VPA) - will result in fewer withdrawal symptoms during detoxification of opiate-polydrug users than the existing treatment regimen, i.e. Clonidine (CLN) combined with Carbamazepine (CBZ). To determine whether there are differences in treatment retention between the BPN/VPA and the CLN/CBZ groups. To assess differences in clinical side-effects and biochemical interactions between the two treatment regimens.

Buprenorphine, a treatment for opioid dependence, can be mixed with naloxone, to limit abuse potential. The purpose of this study is to examine the effectiveness of buprenorphine/naloxone that is given at less than daily intervals, in order to prevent withdrawal symptoms associated with stopping opioid abuse.

Drug abuse and HIV/AIDS are serious global health problems. Injection drug use is currently the major mode of transmission of HIV in many countries. The purpose of this study is to determine the effectiveness of drug and risk reduction counseling combined with either substitution drug treatment with buprenorphine/naloxone (BUP/NX) or short-term detoxification with BUP/NX in preventing HIV transmission among injection drug users. Participants will be recruited for this study in China and Thailand.

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.

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.

Many opioid-dependent individuals are also dependent on cocaine. Methadone is a widely used and effective method for treating opioid dependence. However, it is not effective in treating other drugs of abuse. The purpose of this study is to determine the effectiveness of another drug, tiagabine, for treating cocaine dependence in opioid-dependent individuals already receiving methadone treatment.

The purpose of this study is to determine the efficacy and safety of a buprenorphine/naloxone sublingual tablet formulation as an office-based therapy for opiate-dependence treatment. The developmental objective for this combination product is an expansion of therapeutic options for the treatment of opiate dependence.

The purpose of this study is to evaluate the steady-state pharmacokinetics and bioavailability of buprenorphine sublingual tablets vs. sublingual solution.

The purpose of this study is to determine the safety of lofexidine in the treatment of opiate withdrawal. Preliminary data will also be obtained to assess the ability of lofexidine to alleviate opiate withdrawal signs and symptoms.
