Clinical Trial Summary

Stress is likely involved in relapse to cocaine use. This project will investigate the role oxytocin may play in the stress response in cocaine-dependent men and women and examine how oxytocin may impact brain activity in individuals exposed to cocaine-related cues.

Clinical Trial Description

Stress is an important predictor of relapse, and targeting stress-activated pathways may lead to therapeutic advancements in the treatment of substance use disorders. Oxytocin has been shown to promote trust, social bonding, and calmness; however, its potential effects have not been explored in cocaine-dependent individuals. Oxytocin receptors have been localized to brain regions that are activated by drug-paired cues and preclinical studies have shown that oxytocin attenuates the acute and long-term behavioral effects of psychostimulants. However, little is known about the role of oxytocin in mediating the affective response to cocaine-paired cues and associated neural activity in cocaine-dependent men and women. This project is a direct evolution from our previous SCOR-supported research. Our work has progressed from characterizing sex/gender differences in response to social stressors and cocaine cues in cocaine-dependent men and women, to our on-going work evaluating whether stress potentiates cue-induced craving and the impact of hormones on this response. The proposed study will investigate the role of oxytocin in the sex/gender differences in stress response and craving in cocaine-dependent individuals and preliminarily explore its therapeutic potential. ;
