Official title
Pharmacogenetic Trial of Noradrenergic Medication for Treatment of Cocaine Abuse
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Cocaine use disorders affect approximately 1.5 million Americans annually. Currently, there are no US Food and Drug Administration approved medications for treatment of cocaine dependence; however, both animal and human studies suggest that medications affecting the noradrenergic system can reduce cocaine craving and use. The investigators will study the effect of doxazosin, an alpha-1 adrenergic antagonist, in reducing cocaine use and anxiety symptoms among cocaine-dependent individuals. In addition, the investigators will identify genetic subpopulations of participants who preferentially respond to the medication.
