A team of addiction researchers at the Medical University of South Carolina (MUSC) report in Psychopharmacology that oxytocin, a hormone produced naturally in the hypothalamus, has significant gender differences when used as a treatment for cocaine-addicted individuals with a history of childhood trauma.
The MUSC team was led by Jane E. Joseph, Ph.D., a professor in the Department of Neuroscience, and Kathleen T. Brady, M.D., Ph.D., a professor in the Department of Psychiatry and Behavioral Sciences and MUSC vice president for research.
Oxytocin has been shown to have therapeutic action in addiction, reducing cravings that could result in a relapse while also reducing brain activity associated with stress. Despite previous studies showing some potential therapeutic actions of oxytocin, it was not yet known how oxytocin influenced cravings induced by the sight of cocaine paraphernalia or whether gender-based differences existed.
