Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: All Patients hospitalized in Caen University Hospital with a prescription of hydroxyzine drug. From there, after informing the patient, we will collect the measurement of QT interval before introducing hydroxyzine and the same measure will be performed again on the 3rd day. QT will be corrected by heart rate by Bazett's formula (the most commonly used) and Fridericcia (most reliable). Reproducibility of analyzes inter and intra-individual will be carried out to ensure the reliability of the measurements.

Who may be able to join

  • Patients hospitalized at the University Hospital of Caen with a new prescription of oral hydroxyzine by their referring doctor.
  • Patient 'stable' in hospital in a health service or surgery.
  • Age > 18 years old.

Who cannot join

  • Unstable Patient hospitalized in an intensive care unit or intensive care.
  • Patient refusing participation in the study.
  • Age <18 years old.

About this study

On 04/30/2015, ANSM (the National Security Agency of Medicines and Health Products) shared an information for general practicioners, pediatricians, anesthesiologists, dermatologists, geriatricians, psychiatrists, community pharmacists and hospital about using hydroxyzine and the associated risk of QT prolongation on the electrocardiogram.

Drugs containing hydroxyzine (the best known and most used is the Atarax®) are used in France in various indications including the treatment of minor manifestations of anxiety, premedication with general anesthesia and the symptomatic treatment of urticaria.

A prolonged QT interval is a known risk factor for occurrence of torsades de pointes which can cause sudden death. We distinguish congenital and acquired long QT interval. The main cause of acquired long QT interval is a drug inhibition of the HERG potassium channel 1. Many drugs have been reported to cause sudden death by prolongation of QT interval and occurrence of torsades de pointes (macrolides, anti -arythmics, some psychotropic ...) The molecules based on hydroxyzine are known to be at risk of prolongation of QT interval in an experimental point of view but is not clearly identified in daily clinical practice. Pharmacology unit of Caen was the first to publish a case of QT prolongation under hydroxyzine . Through this publication, associated with other clinical data, hydroxyzine has been added to the list of drugs that can induce QT prolongation .

Despite these recent recommendations, it does not seem that hydroxyzine prescriptions were changed daily and therefore the risk of QT prolongation persists. We therefore propose the study of the impact of hydroxyzine on the QT interval measured on the electrocardiogram in patients hospitalized at the University Hospital of Caen.

What is being measured

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

    Measured: 1 day

Secondary outcomes (2)
  1. Number of Incoming of torsade de pointe

    polymorphic ventricular tachycardia with a characteristic illusion of a twisting of the QRS complex

    Measured: up to 1 month

  2. risk of sudden death by ventricular arythmia

    Measured: up to 1 year

Questions about this trial

What is this clinical trial studying?

An observational study of Hydroxyzine and Long QT Syndrome, run by University Hospital, Caen at 1 site in France.

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 3 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 28 Jun 2016. 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 France. 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.

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?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Measure of the corrected QT interval in ms (time frame: 1 day). 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 28 Jun 2016.
