Filter by:More people worldwide use amphetamine-type stimulants than any illicit drug besides cannabis, and methamphetamine (MA) abuse and dependence is the fastest growing drug problem in the United States. Much work remains in identifying an effective pharmacotherapy for MA dependence. The neurobiological actions produced by MA involve dopamine (DA), serotonin, and norepinephrine, but also include alterations to cholinergic neurotransmitter systems. Candidate compounds that target acetylcholine (ACh) are attractive options for development that have not received adequate attention. Varenicline is a drug that increases the release of DA in the brain and it is logical to assume that it would to some extent compensate for the reduction in these neurotransmitters that occurs in MA withdrawal. Current research has linked certain genes that are related to neurotransmitters with drug abuse and memory impairment (e.g., A1 allele for the D2 dopamine receptor and catechol-O-methyltransferase). We will take blood samples and test for these genes in order to relate the findings to brain function. This is a double-blind, placebo-controlled, within-subjects study to determine the safety and tolerability of MA in MA-dependent volunteers treated with varenicline and placebo.
The purpose of this study is to assess the safety and effectiveness dextroamphetamine to help methamphetamine users quit or cut down on their use. The study lasts for 9 weeks. Eligible participants will attend research visits twice per week, and will receive individual counseling sessions once per week for all 9 weeks. 50% of the participants will receive the active medication while the other 50% will receive the placebo (sugar pill). Neither the participant or the study team will know if the participant is receiving the placebo or active drug.
Patients treated for methamphetamine dependence have high rates of relapse, and no pharmacotherapy has yet been demonstrated to be efficacious. Modafinil (d, l-2-[(diphenylmethyl) sulfinyl] acetamide) is a novel wake- and vigilance- promoting agent that is chemically and pharmacologically dissimilar to CNS stimulants such as the amphetamines, methylphenidate, and pemoline. It is well tolerated and has low abuse liability compared to CNS stimulants. Modafinil is FDA approved for a variety of sleep disorders, may relieve methamphetamine withdrawal symptoms, improves cognitive function, has been shown to reduce cocaine use in dependent users, and is safe when co-administered with intravenous methamphetamine. We will conduct a pilot, open-label clinical trial of modafinil to establish its safety and efficacy as a pharmacotherapy for methamphetamine dependence. Specific Aims: 1. Determine the safety of modafinil in the treatment of methamphetamine dependence. 2. Determine the efficacy of modafinil in the treatment of methamphetamine dependence. 3. Assess the effect of modafinil on cognitive function in methamphetamine users. 4. Assess the effect of modafinil on methamphetamine withdrawal symptoms. 5. Compare the validity of a cellular telephone-based reporting system for assessing medication regimen adherence to conventional electronic medication monitoring. Hypotheses: 1. Modafinil will be as safe and well tolerated as placebo in a comparison group from another study. 2. Subjects given modafinil will use less methamphetamine than subjects given placebo. 3. Subjects given modafinil with demonstrate improvements in cognitive function when compared to subjects given placebo. 4. Subjects given modafinil will have reduced withdrawal symptoms when compared to subjects given placebo. 5. Adherence will be recorded more accurately by cellular telephone than by conventional electronic medication monitoring.
The purpose of this study is to find out if GVG can reduce drug use and determine safety and effects of GVG when used together with methamphetamine. This study involves staying in the hospital for 21 days. Participants will receive either placebo or GVG, and a limited amount if methamphetamine will be injected on some study days. This study will enroll people that use methamphetamine. Participants will be compensated.
