Open Label Pharmaco- Magnetic Resonance Spectrography (MRS) Study of Clavulanic Acid

Summary

The main purpose of this study is to determine how the study drug, clavulanic acid, affects glutamate in the brain using Magnetic Resonance (MR/MRI) scans. In this study, subjects will receive the study drug, clavulanic acid and undergo 4 MRI scans. This is being studied to determine the correct dosing of clavulanic acid, and to gather data so future studies can be done to find out if this drug is helpful in treating cocaine dependence. Currently, there is no available medication treatment for cocaine dependence.
