Filter by:This study will measure the amount of buprenorphine found in the blood after taking sublingual buprenorphine tablets versus after implantation with 4 Probuphine (buprenorphine implants).
This is a 16 week study of the efficacy of quetiapine in treating symptoms of generalized anxiety disorder (GAD) in subjects with comorbid opiate dependence. The study will be conducted in a prospective, randomized, double-blind, and placebo-controlled fashion. Study subjects will be inpatients at a residential drug-treatment facility, enrolled in a 1 year methadone-to-abstinence treatment plan. Subjects will be randomized to receive either quetiapine or placebo in addition to ongoing drug addiction treatment. Subjects will be followed for 16 weeks and a variety of psychometric assessments will be made. Hypothesis One: Compared to placebo, Quetiapine will demonstrate a greater reduction in symptoms of anxiety in subjects with GAD and remitted comorbid opiate abuse. Exploratory Hypotheses: Compared to placebo, Quetiapine will demonstrate a greater improvement in psychosocial functioning and compliance with community norms in subjects enrolled in a residential drug addiction treatment facility.
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.
The purpose of this study is to examine two medications, modafinil and citalopram, in the treatment of cocaine dependent individuals who are maintained on methadone.
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.
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.
Buprenorphine, a treatment for opioid dependence, can be mixed with another drug, naloxone, to limit abuse potential. Parenteral administration (intravenous or intramuscular injection) of buprenorphine/naloxone causes withdrawal symptoms in opioid dependent individuals. However, naloxone does not cause withdrawal symptoms in non-dependent opioid abusers. This study will investigate whether naloxone decreases the opioid agonist effect from injected buprenorphine, hence decreasing the abuse potential of buprenorphine/naloxone, in non-dependent opioid abusers.
Buprenorphine is a drug that may be helpful in treating opioid dependent individuals who were previously maintained on methadone. The purpose of this study is to determine the effects of different doses of buprenorphine/naloxone in treating opioid dependent individuals who were previously maintained on methadone.
