About this study
Official title: Efficacy of Imipramine for Treatment of Patients With Esophageal
Esophageal hypersensitivity/Functional heartburn are common among non-erosive reflux disease (NERD) patients who do not response to proton pump inhibitors. Whether tricyclic antidepressant improves NERD patient's symptoms remains unknown
Aim of this randomized controlled trial study is to determine the efficacy of imipramine, which could increase esophageal pain thresholds in healthy volunteers, in comparison with placebo for treatment patients with esophageal hypersensitivity or functional heartburn evaluated by improvement of specific-symptom score and quality of life
- Conditions
- Gastroesophageal Reflux Disease

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing imipramine in people with Gastroesophageal Reflux Disease, run by Mahidol University at 1 site in Thailand.
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 5 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 18 Aug 2014. 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 Thailand. 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. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
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?
improvement of GERD score (time frame: 6 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 18 Aug 2014; AzTrials last refreshed its copy on 8 Nov 2026.
