About this study
Official title: Impact of Energy Drink Brands on Heart Rhythm in Healthy Volunteers: A Randomized Controlled Trial
To assess the cardiac effects of energy drink brands in healthy volunteers
Read the detailed description
Energy drinks are widely available and globally consumed. There are many brands of energy drinks on the market, and there are differences in the ingredients included. Previous studies have tried to evaluate the safety of energy drinks and have demonstrated a signal for some electrocardiographic (ECG) and hemodynamic effects. However, product related differences need further exploration. This study is designed to assess the effects of 2 different energy drink products on heart rhythm and blood pressure in healthy subjects.
- Conditions
- Electrical Alternation of Heart, Blood Pressure
- Being tested
- Energy Drink Brand 1, Energy Drink Brand 2, Placebo
- Keywords
- ECG, Blood Pressure, Energy Drinks

Questions about this trial
What is this clinical trial studying?
A study testing Energy Drink Brand 1 and Energy Drink Brand 2 in people with Electrical Alternation of Heart and Blood Pressure, run by University of the Pacific at 1 site in United States.
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 2 inclusion and 6 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 24 Dec 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. 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.
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?
Corrected QT (QTc) Interval (time frame: 4 hours). 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 NCT03196908, 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 24 Dec 2018; AzTrials last refreshed its copy on 7 Nov 2026.
