Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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 using a driving simulator.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Active Ethanol and Active Iomazenil

Participants will receive in a randomized, double-blind, cross-over design, ethanol or placebo and iomazenil or placebo.

Potential Randomizations: a) active ethanol and placebo iomazenil, b) active ethanol and active iomazenil, c) placebo ethanol and active iomazenil, and d) placebo ethanol and placebo iomazenil

Group Type EXPERIMENTAL

Active Ethanol

Intervention Type DRUG

Target BrAC of 0.1% reached over 30 minutes and then clamped to maintain this dose for an additional 60 minutes. This dose is equivalent to consuming approximately 5 drinks. Administered over a total of 90 minutes.

Active Iomazenil

Intervention Type DRUG

Active iomazenil, administered intravenously at a dose of 3.7 ug/kg. Administered over 10 minutes, beginning 10 minutes after the start of the ethanol/placebo clamp.

Active Ethanol and Placebo Iomazenil

Participants will receive in a randomized, double-blind, cross-over design, ethanol or placebo and iomazenil or placebo.

Potential Randomizations: a) active ethanol and placebo iomazenil, b) active ethanol and active iomazenil, c) placebo ethanol and active iomazenil, and d) placebo ethanol and placebo iomazenil

Group Type EXPERIMENTAL

Active Ethanol

Intervention Type DRUG

Target BrAC of 0.1% reached over 30 minutes and then clamped to maintain this dose for an additional 60 minutes. This dose is equivalent to consuming approximately 5 drinks. Administered over a total of 90 minutes.

Placebo

Intervention Type DRUG

Control: no iomazenil, administered for a total of 10 minutes

Placebo Ethanol and Active Iomazenil

Participants will receive in a randomized, double-blind, cross-over design, ethanol or placebo and iomazenil or placebo.

Potential Randomizations: a) active ethanol and placebo iomazenil, b) active ethanol and active iomazenil, c) placebo ethanol and active iomazenil, and d) placebo ethanol and placebo iomazenil

Group Type EXPERIMENTAL

Active Iomazenil

Intervention Type DRUG

Placebo

Intervention Type DRUG

Control: no alcohol, administered for a total of 90 minutes.

Placebo Ethanol and Placebo Iomazenil
