Cocaine Use Disorder and Cortical Dopamine

Early Phase 1
Completed
Conditions
Cocaine Dependence
Interventions
Radiation: [C-11]FLB 457
Registration Number
NCT03349606
Lead Sponsor
University of Pittsburgh
Brief Summary

The goal of this study is to use \[C-11\]FLB 457 and amphetamine (oral, 0.5 mg/kg) to measure cortical dopamine transmission in cocaine dependent individuals and healthy controls

Detailed Description

This study seeks to examine dopamine (DA) transmission in vivo, using positron emission tomography (PET) with \[C-11\]FLB 457, in cortical regions of interest in subjects who have a history of cocaine dependence. We hypothesize that cocaine dependence is associated with decreases in dopamine in the prefrontal cortical regions compared to controls. This may explain the impulsivity and cognitive deficits that underlie relapse in this disorder.
