Official title

A Human Laboratory Assessment of the Safety and Potential Efficacy of Varenicline in Methamphetamine-dependent Volunteers Receiving Methamphetamine

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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.
