About this study
This study evaluates the use of Rhodiola rosea in the treatment of Attention Deficit/Hyperactivity Disorder (ADHD) in adults. Half of participants will receive Rhodiola rosea, while the other half will receive placebo.
Read the detailed description
Rhodiola rosea is an herbal medicine used for centuries in various medical conditions. Many randomized controlled trials have evaluated its usefulness in stress and fatigue. There were benefits in attention in some of these studies. Mild side effects and beneficial antioxidant properties make reasonable an assessment of its potential benefits in adults with ADHD. To our knowledge, Rhodiola rosea was never studied in ADHD.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Rhodiola in people with Attention Deficit/Hyperactivity Disorder, run by Hospital de Clinicas de Porto Alegre at 1 site in Brazil.
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 3 inclusion and 10 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: status not confirmed, as of the sponsor's last update on 29 May 2019. 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 Brazil. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Eugenio Grevet, PhD (55 51 3359-8094, ehgrevet@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in Swanson, Nolan and Pelham Rating Scale - Version IV (SNAP-IV) adapted to adults (time frame: Change from baseline SNAP-IV at 4 weeks). 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 NCT02737020, which also lists 19 linked publications.
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 29 May 2019.
