Trial summary

Citalopram is sometimes used in the treatment for gastro-esophageal reflux disease, however, there are no empirical data to support this. The investigators would like to know if citalopram has an effect on the lower esophageal sphincter pressure, transient lower esophageal sphincter relaxations and reflux episodes.

About this study

Official title: Effect of Citalopram on Fasting and Postprandial Lower Esophageal Sphincter Function in Healthy Subjects: a Double-blind, Placebo-controlled, Randomized, Cross-over Study

Citalopram is sometimes used in the treatment for gastro-esophageal reflux disease, however, there are no empirical data to support this. The investigators would like to know if citalopram has an effect on the lower esophageal sphincter pressure, transient lower esophageal sphincter relaxations and reflux episodes. The investigators will investigate this by performing high resolution impedance manometry in healthy volunteers before and after a solid meal. This will be compared to placebo, in a cross-over, randomized, double-blind condition.

Being tested
Citalopram HCl, Placebos
Medical subject headings
Gastroesophageal Reflux

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Citalopram HClDrug

    Citalopram HCl IV 20 mg in 100 ml saline will be infused IV over the course of 30 minutes. Volunteers will receive a standard meal, and recordings using high resolution impedance manometry, will be continued for 2 hours.

  • PlacebosDrug

    Placebo (100 ml saline IV) will be infused IV over the course of 30 minutes. Volunteers will receive a standard meal, and recordings using high resolution impedance manometry, will be continued for 2 hours.

Study groupRoleWhat they receive
Citalopram, 20 mg, IVExperimentalAfter placement of a high resolution impedance manometry catheter (transnasally), citalopram will be administered IV over 30 minutes (20 mg in 100ml saline). Thereafter, the investigators will wait for 20 minutes, after which the volunteers will receive 10 wet swallows (5ml saline), to investigate esophageal peristalsis. Thereafter, a standard meal (1000kcal) will be given to the volunteers and recordings will continue for another 2 hours.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in LES pressure

    The investigators will measure lower esophageal sphincter pressure after a meal between placebo and citalopram, using a high resolution impedance manometry system. LES pressures will be measured in the first hour postprandial and will be compared (preprandial vs postprandial hour 1).

    Measured: LES pressure will be measured for 4 times (a 5 sec time window) per hour. The average of the first hour will be taken as the LES pressure for the first hour postprandially.

  2. Change in the number of reflux episodes

    The investigators will measure the number of reflux episodes after a meal between placebo and citalopram, using a high resolution impedance manometry system.

    Measured: The number of reflux episodes will be counted in a 3 hour time period, to have 1 number of reflux episodes.

  3. Change in the number of TLESRs

    The investigators will measure the number of transient lower esophageal sphincter relaxations after a meal between placebo and citalopram, using a high resolution impedance manometry system.

    Measured: The total number of TLESRs will be counted in a 3 hour time period, to have 1 number of TLESRs.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Citalopram HCl in people with Gastro Esophageal Reflux, run by Universitaire Ziekenhuizen KU Leuven at 1 site in Belgium.

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 1 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 20 Nov 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 Belgium. 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?

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 LES pressure (time frame: LES pressure will be measured for 4 times (a 5 sec time window) per hour. The average of the first hour will be taken as the LES pressure for the first hour postprandially.). The study lists 3 primary outcomes in all. 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 20 Nov 2018.
