Combined Donepezil and Selegiline Effects on Cocaine-Reinforced Behavior

Summary

No medications are currently available for treatment of psychostimulant addiction, a compulsive preoccupation with use of cocaine and related compounds. Donepezil is a medication that is currently prescribed for Alzheimer's disease, and selegiline is a medication used for treatment of Parkinson's Disease. Both of these medications can decrease the amount of cocaine injections that laboratory animals choose to inject by vein. This project will determine if combined treatment with donepezil and selegiline can also decrease cocaine-motivated behavior for human subjects in a laboratory setting.
