The Sustained Effects of Ketamine

Status Terminated

Clinical Trial Summary

The purpose of the study is to characterize the effects of a single, sub-anesthetic dose of ketamine in rs-fMRI in healthy subjects. Post-ketamine rs-fMRI data will demonstrate a pattern of increased global brain connectivity (GBC) in fronto-temporal cortex.

Clinical Trial Description

In this study, healthy participants will be randomized into one of two parallel groups: (a) open-label ketamine and active lamotrigine, or (b) open-label ketamine with a matched-placebo control (i.e., sugar pill). All participants will complete a baseline rs-fMRI approximately 1-week prior to the ketamine infusion and a follow-up rs-fMRI 24-hours post-infusion. The subanesthetic dose of ketamine (0.23mg/kg bolus followed by 0.58mg/kg infusion over approximately 60 minutes) will be administered via intravenous infusion to occur during the MRS scan. Participants will be administered lamotrigine (300 mg oral dose) or the matched-placebo control about 2-hours prior to the start of the infusion. ;
