About this study

Official title: Effects of Alcohol and Energy Drinks on Driving Performance and Bleeding Risk

The main objective of the project is to assess whether there is an interaction between the effects of ethanol and energy drinks on driving performance.

Secondary objectives include: to evaluate subjective effects (drunkenness) after administration of alcohol and energy drinks, to assess pharmacokinetics of alcohol, caffeine and taurine after alcohol and energy drinks administration and to assess if there is an increased risk of bleeding when both drinks are taken together.

Read the detailed description

Consumption of energy drinks improve psychomotor performance and alertness. These drinks contain mostly caffeine, taurine and vitamins. Its consumption associated with ethanol may reduce feelings of drunkenness as the stimulant effects of caffeine could counteract the depressing effects of ethanol on the central nervous system. Reducing the perception of intoxication may predispose the intoxicated person to engage in risky behaviors such as driving under the influence of ethanol and therefore can increase the risk of a traffic accident. Furthermore, the combination of both beverages may increase the risk of bleeding in case of injury as anticoagulant effects have been described for ethanol while antiplatelet effects have been described for caffeine and taurine. A randomized clinical trial will be performed in healthy volunteers administering 4 treatment conditions: alcohol+energy drink, alcohol+placebo of energy drink, placebo of alcohol+energy drink and placebo of alcohol+placebo of energy drink. A multiple dose will be administered separated by 1 hour.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Alcohol and energy drink, Alcohol and Energy drink in people with Alcohol-Related Disorders and Drinking and Driving, run by Parc de Salut Mar at 2 sites in Spain.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 19 Oct 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in tracking test performance (time frame: From baseline till 4 hours after administration). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02771587, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Oct 2016.
