Active clinical trials for "Opioid-Related Disorders"

The purpose of this study is to treat Adult Attention Deficit Hyperactivity Disorder (ADHD) in methadone patients.

The purpose of this study is to evaluate the effect, pharmacokinetics and dose proportionality of buprenorphine when administered to non-dependent opiate users. 1) To evaluate whether plasma concentrations of buprenorphine increase proportionally to buprenorphine dose. 2) To evaluate the dose-response of subjective and physiological effects of buprenorphine; and 3) To determine the safety of buprenorphine.

The CS 1018 study will recruit a total of 600 patients seeking treatment for opiate dependence. They will be recruited from six states (Florida, New York, Texas, California, Washington, and Illinois), with up to ten private physician sites or clinics participating in each state. Coordination of the participating sites and clinics in each of the six states will be performed from an associated Department of Veterans Affairs Medical Center (Tampa VAMC, New York City VAMC, San Antonio VAMC, Long Beach VAMC, Seattle VAMC, and Hines VAMC). The Principal Investigator (PI) at each of the six VAMC?s will be a physician experienced in the treatment of opiate dependent patients. Patients will be recruited by any of numerous strategies including word of mouth, self-referral, local fliers, newspapers, and radio advertisements. This study will be conducted open label with no random assignment or stratification. Patients may be accepted for detoxification or longer-term treatment (6 to 12 months of buprenorphine/naloxone therapy). Patients under the age of 21 will initially be admitted for detoxification; longer treatment of these patients will be based on physician judgement of the necessary of continued treatment. Patients will be inducted directly into buprenorphine/naloxone 4:1 combination tablets. Patients treated in private practice will be asked to sign a treatment contract which will delineate the terms and conditions of treatment.

The purpose of this study is to determine the efficacy of buprenorphine as a substitution pharmacotherapy for opiate dependence.

The purpose of this study is to compare the clinical efficacy of maintenance on low and high doses of buprenorphine with methadone for cocaine abusing opiate addicts.

The purpose of this study is to determine if two times a subject's daily maintenance dose will hold for 48 hours without changes in agonist and antagonist effects.

The purpose of this study is to determine if three times a subject's daily maintenance dose will hold for 72 hours without changes in agonist and antagonist effects.

The purpose of this study is to evaluate buprenorphine and behavioral treatment with and without contingent payment on compliance with pro-social activities. In addition, we will examine whether blind naltrexone dosing is effective in indicating naltrexone consumption.

The purpose of this study is to determine if four times a subjects' daily maintenance dose will hold for 120 hours without changes in agonist and antagonist effects.

The purpose of this study is to determine how subjects will make changes in the amount of medication received when given a monetary alternative to buprenorphine.
