  Purpose
Alcohol is abused commonly, but there is no remedy for alcohol intoxication. This project is looking at the substance iomazenil and its effect on alcohol intoxication and alcohol's effects on driving an automobile.

Detailed Description:
Alcohol is abused commonly, but there is no antidote for alcohol intoxication the way naltrexone or naloxone is an antidote for opioids. A medication that has the potential to block alcohol actions in the Central Nervous System could act as a unique medication in the treatment of alcohol intoxication and alcoholism. This project is evaluating the benzodiazepine partial inverse agonist, iomazenil, as an agent that could reverse alcohol's effects on subjective intoxication, alcohol's effects on driving using a driving simulator and on measures of electrophysiology in the laboratory in healthy subjects.
